+=============================================================================
+The changes below are pre Qt 4.7.0 RC1
+
+TextInput
+   - copy(), cut() and paste() functions added
+Font.letterSpacing
+   - was percentage based.  Now specified in pixels.
+Item
+   - wantsFocus renamed to activeFocus
+   - forceFocus() renamed to forceActiveFocus()
+   - focus now returns the scoped focus (i.e. focus read/write now manipulate
+     the same value)
+TextInput and TextEdit:
+   - focusOnPress renamed to activeFocusOnPress
+
+=============================================================================
+The changes below are pre Qt 4.7.0 beta 2
+
+QDeclarativeView
+   - initialSize() function added
+TextInput and TextEdit: 
+   - openSoftwareInputPanel() and closeSoftwareInputPanel() functions added
+Flickable:
+   - overShoot is replaced by boundsBehavior enumeration
+   - flickingHorizontally and flickingVertically properties added
+   - movingHorizontally and movingVertically properties added
+   - flickDirection is renamed flickableDirection
+Component:
+    - isReady, isLoading, isError and isNull properties removed, use
+      status property instead
+    - errorsString() renamed to errorString()
+ListView:
+    - ListView.prevSection property changed to ListView.previousSection
+TextInput:
+    - xToPosition -> positionAt (to match TextEdit.positionAt)
+Image:
+    - pixmap property removed, use QDeclarativeImageProvider to serve pixmaps
+      instead
+
+QList<QObject*> models no longer provide properties in model object.  The
+properties are now updated when the object changes.  An object's property
+"foo" may now be accessed as "foo", modelData.foo" or model.modelData.foo"
+component.createObject has gained a mandatory "parent" argument
+TextEdit and TextInput now have a "selectByMouse" property that defaults to false.
+
+C++ API
+-------
+QDeclarativeExpression::value() has been renamed to
+QDeclarativeExpression::evaluate()
+
+The QDeclarativeExpression constructor has changed from
+    QDeclarativeExpression(context, expression, scope)
+to
+    QDeclarativeExpression(context, scope, expression, parent = 0)
+
+QDeclarativeImageProvider::request() has been renamed to
+QDeclarativeImageProvider::image() and the class can now provide
+both qimages and qpixmaps, and qimages can be served synchronously
+
+QML Viewer
+------------
+The standalone qml executable has been renamed back to Qml Viewer. Runtime warnings
+can be now accessed via the menu (Debugging->Show Warnings).
+
+=============================================================================
+The changes below are pre Qt 4.7.0 beta 1
+
+TextEdit: wrap property is replaced by wrapMode enumeration.
+Text: wrap property is replaced by wrapMode enumeration.
+Removed Q-prefix from validators (IntValidator, DoubleValidator, and RegExpValidator)
+PathView: offset property now uses range 0-1.0 rather than 0-100
+ListView, GridView::positionViewAtIndex() gained a 'mode' parameter
+Removed Qt.playSound (replaced by SoundEffect element)
+Removed Qt.closestAngle (use RotationAnimation instead)
+Removed NumberFormatter
+Removed DateTimeFormatter (use Qt.formatDateTime() instead)
+Using WebView now requires "import QtWebKit 1.0"
+Using Particles now requires "import Qt.labs.particles 1.0"
+AnchorAnimation must now be used to animate anchor changes (and not NumberAnimation)
+Removed ParentAction (use ParentAnimation instead)
+ScriptAction: renamed stateChangeScriptName -> scriptName
+Animation: replace repeat with loops (loops: Animation.Infinite gives the old repeat behavior)
+AnchorChanges: use natural form to specify anchors (anchors.left instead of left)
+AnchorChanges: removed reset property. (reset: "left" should now be anchors.left: undefined)
+PathView: snapPosition replaced by preferredHighlightBegin, preferredHighlightEnd
+createQmlObject: Moved to the Qt object, now use Qt.createQmlObject()
+createComponent: Moved to the Qt object, now use Qt.createComponent()
+
+C++ API
+-------
+QDeclarativeContext::addDefaultObject() has been replaced with
+QDeclarativeContext::setContextObject()
+
+Behavior and Animation syntax
+-----------------------------
+Previously animations and behaviors could be "assigned" to properties like this:
+    Item { x: Behavior {}; y: NumberAnimation {} }
+To make it more obvious that these are not regular value assignments a new "on"
+syntax has been introduced:
+    Item { Behavior on x {}; NumberAnimation on y {} }
+Only the syntax has changed, the behavior is identical.
+
+EaseFollow renamed to SmoothedFollow
+---------------------------------------
+This element shares the internal implementation with SmoothedAnimation,
+both providing the same easing function, but with SmoothedFollow it's
+easier to set a start value to animate intially and then start to follow,
+while SmoothedAnimation is still convenient for using inside Behaviors
+and Transitions.
+
+
+Add SmoothedAnimation element
+---------------------------------------
+SmoothedAnimation inherits from NumberAnimaton and as a
+consequence SmoothedAnimation can be used inside Behaviors,
+as PropertySourceValues or in state transitions, like any other animation.
+
+The old EaseFollow properties changed to comply with the other declarative
+animations ('source' changed to 'to'), so now 'to' changes are not
+automatically 'followed' anymore.
+
+If you want to follow an hypothetical rect1, you should do now:
+
+     Rectangle {
+         color: "green"
+         width: 60; height: 60;
+         x: rect1.x - 5; y: rect1.y - 5;
+         Behavior on x { SmoothedAnimation { velocity: 200 } }
+         Behavior on y { SmoothedAnimation { velocity: 200 } }
+     }
+
+instead of the old automatic source changed tracking:
+
+     Rectangle {
+         color: "green"
+         width: 60; height: 60;
+         EaseFollow on x { source: rect1.x - 5; velocity: 200 }
+         EaseFollow on y { source: rect1.y - 5; velocity: 200 }
+    }
+
+This is a syntax and behavior change.
+
+
+Script element removed
+----------------------
+Inline Script{} blocks have been deprecated, and will soon be removed entirely.
+If you used Script to write inline javascript code, it can simply be removed.
+For example
+
+Item {
+    Script {
+        function doSomething() {}
+    }
+}
+
+becomes
+
+Item {
+    function doSomething() {}
+}
+
+If you used Script to include external JavaScript files, you can replace the
+Script element with an “import” line.  For example
+
+MouseArea {
+    Script {
+        source: “foo.js”
+    }
+    onClicked: foo()
+}
+
+becomes
+
+import “foo.js” as Foo
+MouseArea {
+    onClicked: Foo.foo()
+}
+
+The “as” qualifier is mandatory for script imports (as opposed to type
+imports where it is optional).
+
+
+=============================================================================
+The changes below are pre Qt 4.7.0 alpha
+
+Flickable: renamed viewportWidth -> contentWidth
+Flickable: renamed viewportHeight -> contentHeight
+Flickable: renamed viewportX -> contentX
+Flickable: renamed viewportY -> contentY
+Removed Flickable.reportedVelocitySmoothing
+Renamed MouseRegion -> MouseArea
+Connection: syntax and rename:
+    Connection { sender: a; signal: foo(); script: xxx }
+    Connection { sender: a; signal: bar(); script: yyy }
+  becomes:
+    Connections { target: a; onFoo: xxx; onBar: yyy }
+
+ListView::sectionExpression has been replaced by section.property, section.criteria
+
+ListModel
+---------
+- types are strictly checked (previously, everything was a string)
+ - foo: "bar"  continues to work as before
+ - foo: bar  is now invalid, use  foo: "bar"
+ - foo: true  is now a bool (not string "true")
+ - foo: false  is now a bool (not string "false" == true!)
+
+PropertyAnimation
+------------------
+matchProperties and matchTargets have been renamed back to properties and targets.
+The semantics are explained in the PropertyAnimation::properties documentation
+and the animation overview documentation.
+
+Easing curves and their parameters are now specified via dot properties:
+* easing.type : enum
+* easing.amplitude : real
+* easing.overshoot : real
+* easing.period : real
+For example:
+PropertyAnimation { properties: "y"; easing.type: "InOutElastic"; easing.amplitude: 2.0; easing.period: 1.5 }
+
+C++ API
+-------
+QML_DEFINE_... definition macros, previously global macros, are replaced by
+qmlRegisterType registration functions, which must be called explicitly.
+C++ API users should also consider using the QmlExtensionPlugin (previously
+named QmlModulePlugin) as a cleaner mechanism for publishing libraries of QML
+types, or the upcoming application plugin features of the qmlviewer /
+qmlruntime / qml.
+
+QmlView
+-------
+The API of QmlView has been narrowed and its role as a convenience class
+reinforced.
+- remove addItem()
+- remove clearItems() - use 'delete root()'
+- remove reset()
+- resizeContent -> enum ResizeMode { SizeViewToRootObject, SizeRootObjectToView }
+- remove setQml(), qml()
+- rename setUrl(), ur() to setSource(), source()
+- root() -> rootObject(),  returns QGraphicsObject rather than QmlGraphicsItem
+- remove quit() signal -> use quit() signal of engine()
+- initialSize() signal removed
+- Added status() to determine status of the internal QmlComponent
+- removed execute() - setSource() will also execute the QML.
+
+
+=============================================================================
+The changes below are pre-4.6.0 release.
+
+QML API Review
+==============
+
+The QML API is being reviewed.  This file documents the changes.
+Note that the changes are incremental, so a rename A->B for example may be followed
+by another subsequent rename B->C, if later reviews override earlier reviews.

+/*!
+  \class QPacketProtocol
+  \internal
+
+  \brief The QPacketProtocol class encapsulates communicating discrete packets
+  across fragmented IO channels, such as TCP sockets.
+
+  QPacketProtocol makes it simple to send arbitrary sized data "packets" across 
+  fragmented transports such as TCP and UDP.
+
+  As transmission boundaries are not respected, sending packets over protocols
+  like TCP frequently involves "stitching" them back together at the receiver.
+  QPacketProtocol makes this easier by performing this task for you.  Packet
+  data sent using QPacketProtocol is prepended with a 4-byte size header
+  allowing the receiving QPacketProtocol to buffer the packet internally until
+  it has all been received.  QPacketProtocol does not perform any sanity
+  checking on the size or on the data, so this class should only be used in
+  prototyping or trusted situations where DOS attacks are unlikely.
+
+  QPacketProtocol does not perform any communications itself.  Instead it can
+  operate on any QIODevice that supports the QIODevice::readyRead() signal.  A
+  logical "packet" is encapsulated by the companion QPacket class.  The
+  following example shows two ways to send data using QPacketProtocol.  The
+  transmitted data is equivalent in both.
+
+  \code
+  QTcpSocket socket;
+  // ... connect socket ...
+
+  QPacketProtocol protocol(&socket);
+
+  // Send packet the quick way

+
+  \brief The QPacket class encapsulates an unfragmentable packet of data to be
+  transmitted by QPacketProtocol.
+
+  The QPacket class works together with QPacketProtocol to make it simple to
+  send arbitrary sized data "packets" across fragmented transports such as TCP
+  and UDP.
+
+  QPacket provides a QDataStream interface to an unfragmentable packet.
+  Applications should construct a QPacket, propagate it with data and then
+  transmit it over a QPacketProtocol instance.  For example:
+  \code
+  QPacketProtocol protocol(...);
+
+  QPacket myPacket;
+  myPacket << "Hello world!" << 123;
+  protocol.send(myPacket);
+  \endcode
+
+  As long as both ends of the connection are using the QPacketProtocol class,
+  the data within this packet will be delivered unfragmented at the other end,
+  ready for extraction.
+
+  \code
+  QByteArray greeting;
+  int count;
+
+  QPacket myPacket = protocol.read();
+
+  myPacket >> greeting >> count;
+  \endcode
+
+  Only packets returned from QPacketProtocol::read() may be read from.  QPacket
+  instances constructed by directly by applications are for transmission only 
+  and are considered "write only".  Attempting to read data from them will 
+  result in undefined behavior.

+
+    The AnimatedImage element extends the features of the \l Image element, providing
+    a way to play animations stored as images containing a series of frames,
+    such as those stored in GIF files.
+
+    Information about the current frame and totla length of the animation can be
+    obtained using the \l currentFrame and \l frameCount properties. You can
+    start, pause and stop the animation by changing the values of the \l playing
+    and \l paused properties.
+
+    The full list of supported formats can be determined with QMovie::supportedFormats().
+
+    \section1 Example Usage
+
+    \beginfloatleft
+    \image animatedimageitem.gif
+    \endfloat
+
+    The following QML shows how to display an animated image and obtain information
+    about its state, such as the current frame and total number of frames.
+    The result is an animated image with a simple progress indicator underneath it.

+    \qmlclass BorderImage QDeclarativeBorderImage
+    \brief The BorderImage element provides an image that can be used as a border.
+    \inherits Item
+    \since 4.7
+    \ingroup qml-basic-visual-elements
+
+    The BorderImage element is used to create borders out of images by scaling or tiling
+    parts of each image.
+
+    A BorderImage element breaks a source image, specified using the \l url property,
+    into 9 regions, as shown below:
+
+    \image declarative-scalegrid.png
+
+    When the image is scaled, regions of the source image are scaled or tiled to
+    create the displayed border image in the following way:
+
+    \list
+    \i The corners (regions 1, 3, 7, and 9) are not scaled at all.
+    \i Regions 2 and 8 are scaled according to
+       \l{BorderImage::horizontalTileMode}{horizontalTileMode}.
+    \i Regions 4 and 6 are scaled according to
+       \l{BorderImage::verticalTileMode}{verticalTileMode}.
+    \i The middle (region 5) is scaled according to both
+       \l{BorderImage::horizontalTileMode}{horizontalTileMode} and
+       \l{BorderImage::verticalTileMode}{verticalTileMode}.
+    \endlist
+
+    The regions of the image are defined using the \l border property group, which
+    describes the distance from each edge of the source image to use as a border.
+
+    \section1 Example Usage
+
+    The following examples show the effects of the different modes on an image.
+    Guide lines are overlaid onto the image to show the different regions of the
+    image as described above.
+
+    \beginfloatleft
+    \image qml-borderimage-normal-image.png
+    \endfloat
+
+    An unscaled image is displayed using an Image element. The \l border property is
+    used to determine the parts of the image that will lie inside the unscaled corner
+    areas and the parts that will be stretched horizontally and vertically.
+
+    \snippet doc/src/snippets/declarative/borderimage/normal-image.qml normal image
+
+    \clearfloat
+    \beginfloatleft
+    \image qml-borderimage-scaled.png
+    \endfloat
+
+    A BorderImage element is used to display the image, and it is given a size that is
+    larger than the original image. Since the \l horizontalTileMode property is set to
+    \l{BorderImage::horizontalTileMode}{BorderImage.Stretch}, the parts of image in
+    regions 2 and 8 are stretched horizontally. Since the \l verticalTileMode property
+    is set to \l{BorderImage::verticalTileMode}{BorderImage.Stretch}, the parts of image
+    in regions 4 and 6 are stretched vertically.
+
+    \snippet doc/src/snippets/declarative/borderimage/borderimage-scaled.qml scaled border image
+
+    \clearfloat
+    \beginfloatleft
+    \image qml-borderimage-tiled.png
+    \endfloat
+
+    Again, a large BorderImage element is used to display the image. With the
+    \l horizontalTileMode property set to \l{BorderImage::horizontalTileMode}{BorderImage.Repeat},
+    the parts of image in regions 2 and 8 are tiled so that they fill the space at the
+    top and bottom of the element. Similarly, the \l verticalTileMode property is set to
+    \l{BorderImage::verticalTileMode}{BorderImage.Repeat}, the parts of image in regions
+    4 and 6 are tiled so that they fill the space at the left and right of the element.
+
+    \snippet doc/src/snippets/declarative/borderimage/borderimage-tiled.qml tiled border image
+
+    \clearfloat
+    In some situations, the width of regions 2 and 8 may not be an exact multiple of the width
+    of the corresponding regions in the source image. Similarly, the height of regions 4 and 6
+    may not be an exact multiple of the height of the corresponding regions. It can be useful
+    to use \l{BorderImage::horizontalTileMode}{BorderImage.Round} instead of
+    \l{BorderImage::horizontalTileMode}{BorderImage.Repeat} in cases like these.
+
+    The \l{declarative/imageelements/borderimage}{BorderImage example} shows how a BorderImage
+    can be used to simulate a shadow effect on a rectangular item.
+
+    \section1 Quality and Performance
+
+    By default, any scaled regions of the image are rendered without smoothing to improve
+    rendering speed. Setting the \l smooth property improves rendering quality of scaled
+    regions, but may slow down rendering.
+
+    The source image may not be loaded instantaneously, depending on its original location.
+    Loading progress can be monitored with the \l progress property.

+/*!
+    \qmlproperty int KeyEvent::key
+
+    This property holds the code of the key that was pressed or released.
+
+    See \l {Qt::Key}{Qt.Key} for the list of keyboard codes. These codes are
+    independent of the underlying window system. Note that this
+    function does not distinguish between capital and non-capital
+    letters, use the text() function (returning the Unicode text the
+    key generated) for this purpose.
+
+    A value of either 0 or \l {Qt::Key_unknown}{Qt.Key_Unknown} means that the event is not
+    the result of a known key; for example, it may be the result of
+    a compose sequence, a keyboard macro, or due to key event
+    compression.
+*/
+

+
+/*!
+    \qmlproperty bool KeyEvent::accepted
+
+    Setting \a accepted to true prevents the key event from being

+    so that ancestor items do not also respond to the same event.
+*/
+
+/*!
+    \qmlproperty int KeyEvent::modifiers

+
+    \brief The Flickable item provides a surface that can be "flicked".
+    \inherits Item
+
+    The Flickable item places its children on a surface that can be dragged
+    and flicked, causing the view onto the child items to scroll. This
+    behavior forms the basis of Items that are designed to show large numbers
+    of child items, such as \l ListView and \l GridView.
+
+    In traditional user interfaces, views can be scrolled using standard
+    controls, such as scroll bars and arrow buttons. In some situations, it
+    is also possible to drag the view directly by pressing and holding a
+    mouse button while moving the cursor. In touch-based user interfaces,
+    this dragging action is often complemented with a flicking action, where
+    scrolling continues after the user has stopped touching the view.
+
+    Flickable does not automatically clip its contents. If it is not used as
+    a full-screen item, you should consider setting the \l{Item::}{clip} property
+    to true.
+
+    \section1 Example Usage
+
+    \div {class="float-right"}
+    \inlineimage flickable.gif
+    \enddiv
+
+    The following example shows a small view onto a large image in which the
+    user can drag or flick the image in order to view different parts of it.
+
+    \snippet doc/src/snippets/declarative/flickable.qml document
+
+    \clearfloat
+
+    Items declared as children of a Flickable are automatically parented to the
+    Flickable's \l contentItem.  This should be taken into account when
+    operating on the children of the Flickable; it is usually the children of
+    \c contentItem that are relevant.  For example, the bound of Items added
+    to the Flickable will be available by \c contentItem.childrenRect
+
+    \section1 Limitations
+
+    \note Due to an implementation detail, items placed inside a Flickable cannot anchor to it by
+    \c id. Use \c parent instead.

+    \since 4.7
+    \ingroup qml-basic-interaction-elements
+    \brief The Flipable item provides a surface that can be flipped.
+    \inherits Item
+
+    Flipable is an item that can be visibly "flipped" between its front and
+    back sides, like a card. It is used together with \l Rotation, \l State
+    and \l Transition elements to produce a flipping effect.
+
+    The \l front and \l back properties are used to hold the items that are
+    shown respectively on the front and back sides of the flipable item.
+
+    \section1 Example Usage
+
+    The following example shows a Flipable item that flips whenever it is
+    clicked, rotating about the y-axis.
+
+    This flipable item has a \c flipped boolean property that is toggled
+    whenever the MouseArea within the flipable is clicked. When
+    \c flipped is true, the item changes to the "back" state; in this
+    state, the \c angle of the \l Rotation item is changed to 180
+    degrees to produce the flipping effect. When \c flipped is false, the
+    item reverts to the default state, in which the \c angle value is 0.
+
+    \snippet doc/src/snippets/declarative/flipable/flipable.qml 0
+
+    \image flipable.gif
+
+    The \l Transition creates the animation that changes the angle over
+    four seconds. When the item changes between its "back" and
+    default states, the NumberAnimation animates the angle between
+    its old and new values.
+
+    See \l {QML States} for details on state changes and the default
+    state, and \l {QML Animation and Transitions} for more information on how
+    animations work within transitions.

+    \qmlclass GridView QDeclarativeGridView
+    \since 4.7
+    \ingroup qml-view-elements
+
+    \inherits Flickable
+    \brief The GridView item provides a grid view of items provided by a model.
+
+    A GridView displays data from models created from built-in QML elements like ListModel
+    and XmlListModel, or custom model classes defined in C++ that inherit from
+    QAbstractListModel.
+
+    A GridView has a \l model, which defines the data to be displayed, and
+    a \l delegate, which defines how the data should be displayed. Items in a 
+    GridView are laid out horizontally or vertically. Grid views are inherently flickable
+    as GridView inherits from \l Flickable.
+
+    \section1 Example Usage
+
+    The following example shows the definition of a simple list model defined
+    in a file called \c ContactModel.qml:
+
+    \snippet doc/src/snippets/declarative/gridview/ContactModel.qml 0
+
+    \div {class="float-right"}
+    \inlineimage gridview-simple.png
+    \enddiv
+
+    This model can be referenced as \c ContactModel in other QML files. See \l{QML Modules}
+    for more information about creating reusable components like this.
+
+    Another component can display this model data in a GridView, as in the following
+    example, which creates a \c ContactModel component for its model, and a \l Column element
+    (containing \l Image and \l Text elements) for its delegate.
+
+    \clearfloat
+    \snippet doc/src/snippets/declarative/gridview/gridview.qml import
+    \codeline
+    \snippet doc/src/snippets/declarative/gridview/gridview.qml classdocs simple
+
+    \div {class="float-right"}
+    \inlineimage gridview-highlight.png
+    \enddiv
+
+    The view will create a new delegate for each item in the model. Note that the delegate
+    is able to access the model's \c name and \c portrait data directly.
+
+    An improved grid view is shown below. The delegate is visually improved and is moved 
+    into a separate \c contactDelegate component.
+
+    \clearfloat
+    \snippet doc/src/snippets/declarative/gridview/gridview.qml classdocs advanced
+
+    The currently selected item is highlighted with a blue \l Rectangle using the \l highlight property,
+    and \c focus is set to \c true to enable keyboard navigation for the grid view.
+    The grid view itself is a focus scope (see \l{qmlfocus#Acquiring Focus and Focus Scopes}{the focus documentation page} for more details).
+
+    Delegates are instantiated as needed and may be destroyed at any time.
+    State should \e never be stored in a delegate.
+
+    GridView attaches a number of properties to the root item of the delegate, for example
+    \c {GridView.isCurrentItem}.  In the following example, the root delegate item can access
+    this attached property directly as \c GridView.isCurrentItem, while the child
+    \c contactInfo object must refer to this property as \c wrapper.GridView.isCurrentItem.
+
+    \snippet doc/src/snippets/declarative/gridview/gridview.qml isCurrentItem
+
+    \note Views do not set the \l{Item::}{clip} property automatically.
+    If the view is not clipped by another item or the screen, it will be necessary
+    to set this property to true in order to clip the items that are partially or
+    fully outside the view.

+
+    Positions the view such that the \a index is at the position specified by
+    \a mode:
+
+    \list
+    \o GridView.Beginning - position item at the top (or left for \c GridView.TopToBottom flow) of the view.
+    \o GridView.Center - position item in the center of the view.
+    \o GridView.End - position item at bottom (or right for horizontal orientation) of the view.
+    \o GridView.Visible - if any part of the item is visible then take no action, otherwise
+    bring the item into view.
+    \o GridView.Contain - ensure the entire item is visible.  If the item is larger than
+    the view the item is positioned at the top (or left for \c GridView.TopToBottom flow) of the view.
+    \endlist
+
+    If positioning the view at the index would cause empty space to be displayed at
+    the beginning or end of the view, the view will be positioned at the boundary.
+
+    It is not recommended to use \l {Flickable::}{contentX} or \l {Flickable::}{contentY} to position the view
+    at a particular index.  This is unreliable since removing items from the start
+    of the view does not cause all other items to be repositioned.
+    The correct way to bring an item into view is with \c positionViewAtIndex.
+
+    \bold Note: methods should only be called after the Component has completed.  To position
+    the view at startup, this method should be called by Component.onCompleted.  For
+    example, to position the view at the end:

+    \qmlclass Image QDeclarativeImage
+    \since 4.7
+    \ingroup qml-basic-visual-elements
+    \brief The Image element displays an image in a declarative user interface
+    \inherits Item
+
+    The Image element is used to display images in a declarative user interface.
+
+    The source of the image is specified as a URL using the \l source property.
+    Images can be supplied in any of the standard image formats supported by Qt,
+    including bitmap formats such as PNG and JPEG, and vector graphics formats
+    such as SVG. If you need to display animated images, use the \l AnimatedImage
+    element.
+
+    If the \l{Item::width}{width} and \l{Item::height}{height} properties are not
+    specified, the Image element automatically uses the size of the loaded image.
+    By default, specifying the width and height of the element causes the image
+    to be scaled to that size. This behavior can be changed by setting the
+    \l fillMode property, allowing the image to be stretched and tiled instead.
+
+    \section1 Example Usage
+
+    The following example shows the simplest usage of the Image element.
+
+    \snippet doc/src/snippets/declarative/image.qml document
+
+    \beginfloatleft
+    \image declarative-qtlogo.png
+    \endfloat
+
+    \clearfloat
+
+    \section1 Performance
+
+    By default, locally available images are loaded immediately, and the user interface
+    is blocked until loading is complete. If a large image is to be loaded, it may be
+    preferable to load the image in a low priority thread, by enabling the \l asynchronous
+    property.
+
+    If the image is obtained from a network rather than a local resource, it is
+    automatically loaded asynchronously, and the \l progress and \l status properties
+    are updated as appropriate.
+
+    Images are cached and shared internally, so if several Image elements have the same \l source,
+    only one copy of the image will be loaded.
+
+    \bold Note: Images are often the greatest user of memory in QML user interfaces.  It is recommended
+    that images which do not form part of the user interface have their
+    size bounded via the \l sourceSize property. This is especially important for content
+    that is loaded from external sources or provided by the user.

+    \qmlproperty QSize Image::sourceSize
+
+    This property holds the actual width and height of the loaded image.
+
+    Unlike the \l {Item::}{width} and \l {Item::}{height} properties, which scale
+    the painting of the image, this property sets the actual number of pixels
+    stored for the loaded image so that large images do not use more
+    memory than necessary. For example, this ensures the image in memory is no
+    larger than 1024x1024 pixels, regardless of the Image's \l {Item::}{width} and 
+    \l {Item::}{height} values:
+
+    \code
+    Rectangle {
+        width: ...
+        height: ...
+
+        Image {
+           anchors.fill: parent
+           source: "reallyBigImage.jpg"
+           sourceSize.width: 1024
+           sourceSize.height: 1024
+        }
+    }
+    \endcode
+
+    If the image's actual size is larger than the sourceSize, the image is scaled down.
+    If only one dimension of the size is set to greater than 0, the
+    other dimension is set in proportion to preserve the source image's aspect ratio.
+    (The \l fillMode is independent of this.)
+
+    If the source is an instrinsically scalable image (eg. SVG), this property
+    determines the size of the loaded image regardless of intrinsic size.
+    Avoid changing this property dynamically; rendering an SVG is \e slow compared
+    to an image.
+
+    If the source is a non-scalable image (eg. JPEG), the loaded image will
+    be no greater than this property specifies. For some formats (currently only JPEG),
+    the whole image will never actually be loaded into memory.
+
+    Since QtQuick 1.1 the sourceSize can be cleared to the natural size of the image
+    by setting sourceSize to \c undefined.
+ 
+    \note \e {Changing this property dynamically causes the image source to be reloaded,
+    potentially even from the network, if it is not in the disk cache.}

+    \brief The Rotation object provides a way to rotate an Item.
+
+    The Rotation object gives more control over rotation than using \l Item's \l{Item::rotation}{rotation} property.
+    Specifically, it allows (z axis) rotation to be relative to an arbitrary point.

+    \qmlclass KeyNavigation QDeclarativeKeyNavigationAttached
+    \ingroup qml-basic-interaction-elements
+    \since 4.7
+    \brief The KeyNavigation attached property supports key navigation by arrow keys.
+
+    Key-based user interfaces commonly allow the use of arrow keys to navigate between
+    focusable items.  The KeyNavigation attached property enables this behavior by providing a
+    convenient way to specify the item that should gain focus when an arrow or tab key is pressed.
+
+    The following example provides key navigation for a 2x2 grid of items:
+
+    \snippet doc/src/snippets/declarative/keynavigation.qml 0
+
+    The top-left item initially receives focus by setting \l {Item::}{focus} to
+    \c true. When an arrow key is pressed, the focus will move to the
+    appropriate item, as defined by the value that has been set for
+    the KeyNavigation \l left, \l right, \l up or \l down properties.
+
+    Note that if a KeyNavigation attached property receives the key press and release
+    events for a requested arrow or tab key, the event is accepted and does not
+    propagate any further.
+
+    By default, KeyNavigation receives key events after the item to which it is attached.
+    If the item accepts the key event, the KeyNavigation attached property will not
+    receive an event for that key.  Setting the \l priority property to
+    \c KeyNavigation.BeforeItem allows the event to be used for key navigation
+    before the item, rather than after.
+
+    If item to which the focus is switching is not enabled or visible, an attempt will
+    be made to skip this item and focus on the next. This is possible if there are
+    a chain of items with the same KeyNavigation handler. If multiple items in a row are not enabled
+    or visible, they will also be skipped.

+    \qmlclass LayoutMirroring QDeclarativeLayoutMirroringAttached
+    \since QtQuick 1.1
+    \ingroup qml-utility-elements
+    \brief The LayoutMirroring attached property is used to mirror layout behavior.
+
+    The LayoutMirroring attached property is used to horizontally mirror \l {anchor-layout}{Item anchors},
+    \l{Using QML Positioner and Repeater Items}{positioner} elements (such as \l Row and \l Grid)
+    and views (such as \l GridView and horizontal \l ListView). Mirroring is a visual change: left
+    anchors become right anchors, and positioner elements like \l Grid and \l Row reverse the
+    horizontal layout of child items.
+
+    Mirroring is enabled for an item by setting the \l enabled property to true. By default, this
+    only affects the item itself; setting the \l childrenInherit property to true propagates the mirroring
+    behavior to all child elements as well. If the \c LayoutMirroring attached property has not been defined
+    for an item, mirroring is not enabled.
+
+    The following example shows mirroring in action. The \l Row below is specified as being anchored
+    to the left of its parent. However, since mirroring has been enabled, the anchor is horizontally
+    reversed and it is now anchored to the right. Also, since items in a \l Row are positioned
+    from left to right by default, they are now positioned from right to left instead, as demonstrated
+    by the numbering and opacity of the items:
+
+    \snippet doc/src/snippets/declarative/layoutmirroring.qml 0
+
+    \image layoutmirroring.png
+
+    Layout mirroring is useful when it is necessary to support both left-to-right and right-to-left
+    layout versions of an application to target different language areas. The \l childrenInherit
+    property allows layout mirroring to be applied without manually setting layout configurations
+    for every item in an application. Keep in mind, however, that mirroring does not affect any
+    positioning that is defined by the \l Item \l {Item::}{x} coordinate value, so even with
+    mirroring enabled, it will often be necessary to apply some layout fixes to support the
+    desired layout direction. Also, it may be necessary to disable the mirroring of individual
+    child items (by setting \l {enabled}{LayoutMirroring.enabled} to false for such items) if
+    mirroring is not the desired behavior, or if the child item already implements mirroring in
+    some custom way.
+
+    See \l {QML Right-to-left User Interfaces} for further details on using \c LayoutMirroring and
+    other related features to implement right-to-left support for an application.

+    \qmlclass Keys QDeclarativeKeysAttached
+    \ingroup qml-basic-interaction-elements
+    \since 4.7
+    \brief The Keys attached property provides key handling to Items.
+
+    All visual primitives support key handling via the Keys
+    attached property.  Keys can be handled via the onPressed
+    and onReleased signal properties.
+
+    The signal properties have a \l KeyEvent parameter, named
+    \e event which contains details of the event.  If a key is
+    handled \e event.accepted should be set to true to prevent the
+    event from propagating up the item hierarchy.
+
+    \section1 Example Usage
+
+    The following example shows how the general onPressed handler can
+    be used to test for a certain key; in this case, the left cursor
+    key:
+
+    \snippet doc/src/snippets/declarative/keys/keys-pressed.qml key item
+
+    Some keys may alternatively be handled via specific signal properties,
+    for example \e onSelectPressed.  These handlers automatically set
+    \e event.accepted to true.
+
+    \snippet doc/src/snippets/declarative/keys/keys-handler.qml key item
+
+    See \l{Qt::Key}{Qt.Key} for the list of keyboard codes.
+
+    \section1 Key Handling Priorities
+
+    The Keys attached property can be configured to handle key events
+    before or after the item it is attached to. This makes it possible
+    to intercept events in order to override an item's default behavior,
+    or act as a fallback for keys not handled by the item.
+
+    If \l priority is Keys.BeforeItem (default) the order of key event processing is:
+
+    \list 1
+    \o Items specified in \c forwardTo
+    \o specific key handlers, e.g. onReturnPressed
+    \o onKeyPress, onKeyRelease handlers
+    \o Item specific key handling, e.g. TextInput key handling
+    \o parent item
+    \endlist
+
+    If priority is Keys.AfterItem the order of key event processing is:
+
+    \list 1
+    \o Item specific key handling, e.g. TextInput key handling
+    \o Items specified in \c forwardTo
+    \o specific key handlers, e.g. onReturnPressed
+    \o onKeyPress, onKeyRelease handlers
+    \o parent item
+    \endlist
+
+    If the event is accepted during any of the above steps, key
+    propagation stops.

+/*!
+    \qmlproperty list<Object> Keys::forwardTo
+
+    This property provides a way to forward key presses, key releases, and keyboard input

+
+    All visual items in Qt Declarative inherit from Item.  Although Item
+    has no visual appearance, it defines all the properties that are
+    common across visual items - such as the x and y position, the
+    width and height, \l {anchor-layout}{anchoring} and key handling.
+
+    Item is also useful for grouping items together.

+        Image {
+            source: "tile.png"

+
+
+    \section1 Key Handling
+
+    Key handling is available to all Item-based visual elements via the \l {Keys}{Keys}
+    attached property.  The \e Keys attached property provides basic handlers such
+    as \l {Keys::onPressed}{onPressed} and \l {Keys::onReleased}{onReleased},
+    as well as handlers for specific keys, such as
+    \l {Keys::onCancelPressed}{onCancelPressed}.  The example below
+    assigns \l {qmlfocus}{focus} to the item and handles
+    the Left key via the general \e onPressed handler and the Select key via the
+    onSelectPressed handler:
+
+    \qml
+    Item {
+        focus: true
+        Keys.onPressed: {
+            if (event.key == Qt.Key_Left) {
+                console.log("move left");
+                event.accepted = true;
+            }
+        }
+        Keys.onSelectPressed: console.log("Selected");
+    }
+    \endqml
+
+    See the \l {Keys}{Keys} attached property for detailed documentation.
+
+    \section1 Layout Mirroring
+
+    Item layouts can be mirrored using the \l {LayoutMirroring}{LayoutMirroring} attached property.

+    \qmlclass LayoutItem QDeclarativeLayoutItem
+    \ingroup qml-utility-elements
+    \since 4.7
+    \brief The LayoutItem element allows declarative UI elements to be placed inside Qt's Graphics View layouts.
+
+    LayoutItem is a variant of \l Item with additional size hint properties. These properties provide the size hints
+    necessary for items to work in conjunction with Qt \l{Graphics View Framework}{Graphics View} layout classes
+    such as QGraphicsLinearLayout and QGraphicsGridLayout. The Qt layout mechanisms will resize the LayoutItem as appropriate,
+    taking its size hints into account, and you can propagate this to the other elements in your UI via anchors and bindings.
+
+    This is a QGraphicsLayoutItem subclass, and its properties merely expose the QGraphicsLayoutItem functionality to QML.
+
+    The \l{declarative/cppextensions/qgraphicslayouts/layoutitem}{LayoutItem example}
+    demonstrates how a LayoutItem can be used within a \l{Graphics View Framework}{Graphics View}
+    scene.

+    \qmlclass ListView QDeclarativeListView
+    \ingroup qml-view-elements
+    \since 4.7
+    \inherits Flickable
+    \brief The ListView item provides a list view of items provided by a model.
+
+    A ListView displays data from models created from built-in QML elements like ListModel
+    and XmlListModel, or custom model classes defined in C++ that inherit from
+    QAbstractListModel.
+
+    A ListView has a \l model, which defines the data to be displayed, and
+    a \l delegate, which defines how the data should be displayed. Items in a
+    ListView are laid out horizontally or vertically. List views are inherently
+    flickable because ListView inherits from \l Flickable.
+
+    \section1 Example Usage
+
+    The following example shows the definition of a simple list model defined
+    in a file called \c ContactModel.qml:
+
+    \snippet doc/src/snippets/declarative/listview/ContactModel.qml 0
+
+    Another component can display this model data in a ListView, like this:
+
+    \snippet doc/src/snippets/declarative/listview/listview.qml import
+    \codeline
+    \snippet doc/src/snippets/declarative/listview/listview.qml classdocs simple
+
+    \image listview-simple.png
+
+    Here, the ListView creates a \c ContactModel component for its model, and a \l Text element
+    for its delegate. The view will create a new \l Text component for each item in the model. Notice
+    the delegate is able to access the model's \c name and \c number data directly.
+
+    An improved list view is shown below. The delegate is visually improved and is moved 
+    into a separate \c contactDelegate component.
+
+    \snippet doc/src/snippets/declarative/listview/listview.qml classdocs advanced
+    \image listview-highlight.png
+
+    The currently selected item is highlighted with a blue \l Rectangle using the \l highlight property,
+    and \c focus is set to \c true to enable keyboard navigation for the list view.
+    The list view itself is a focus scope (see \l{qmlfocus#Acquiring Focus and Focus Scopes}{the focus documentation page} for more details).
+
+    Delegates are instantiated as needed and may be destroyed at any time.
+    State should \e never be stored in a delegate.
+
+    ListView attaches a number of properties to the root item of the delegate, for example
+    \c {ListView.isCurrentItem}.  In the following example, the root delegate item can access
+    this attached property directly as \c ListView.isCurrentItem, while the child
+    \c contactInfo object must refer to this property as \c wrapper.ListView.isCurrentItem.
+
+    \snippet doc/src/snippets/declarative/listview/listview.qml isCurrentItem
+
+    \note Views do not enable \e clip automatically.  If the view
+    is not clipped by another item or the screen, it will be necessary
+    to set \e {clip: true} in order to have the out of view items clipped

+    instantiated as it can fit within the buffer specified.  For example,

+
+    Note that cacheBuffer is not a pixel buffer - it only maintains additional
+    instantiated delegates.
+
+    Setting this value can improve the smoothness of scrolling behavior at the expense
+    of additional memory usage.  It is not a substitute for creating efficient
+    delegates; the fewer elements in a delegate, the faster a view can be

+
+    These properties hold the expression to be evaluated for the \l section attached property.
+
+    The \l section attached property enables a ListView to be visually
+    separated into different parts. These properties determine how sections
+    are created.
+    
+    \c section.property holds the name of the property that is the basis
+    of each section.
+
+    \c section.criteria holds the criteria for forming each section based on
+    \c section.property. This value can be one of:
+
+    \list
+    \o ViewSection.FullString (default) - sections are created based on the 
+    \c section.property value.
+    \o ViewSection.FirstCharacter - sections are created based on the first
+    character of the \c section.property value (for example, 'A', 'B', 'C' 
+    sections, etc. for an address book)
+    \endlist
+
+    \c section.delegate holds the delegate component for each section.
+
+    Each item in the list has attached properties named \c ListView.section,
+    \c ListView.previousSection and \c ListView.nextSection.  These may be
+    used to place a section header for related items.
+
+    For example, here is a ListView that displays a list of animals, separated 
+    into sections. Each item in the ListView is placed in a different section 
+    depending on the "size" property of the model item. The \c sectionHeading
+    delegate component provides the light blue bar that marks the beginning of
+    each section.

+
+    \note Adding sections to a ListView does not automatically re-order the
+    list items by the section criteria.
+    If the model is not ordered by section, then it is possible that
+    the sections created will not be unique; each boundary between
+    differing sections will result in a section header being created
+    even if that section exists elsewhere.

+    \qmlclass Loader QDeclarativeLoader
+    \ingroup qml-utility-elements
+    \since 4.7
+    \inherits Item
+
+    \brief The Loader item allows dynamically loading an Item-based
+    subtree from a URL or Component.
+
+    Loader is used to dynamically load visual QML components. It can load a
+    QML file (using the \l source property) or a \l Component object (using 
+    the \l sourceComponent property). It is useful for delaying the creation 
+    of a component until it is required: for example, when a component should 
+    be created on demand, or when a component should not be created 
+    unnecessarily for performance reasons.
+
+    Here is a Loader that loads "Page1.qml" as a component when the 
+    \l MouseArea is clicked:
+
+    \snippet doc/src/snippets/declarative/loader/simple.qml 0
+
+    The loaded item can be accessed using the \l item property.
+
+    If the \l source or \l sourceComponent changes, any previously instantiated
+    items are destroyed. Setting \l source to an empty string or setting
+    \l sourceComponent to \c undefined destroys the currently loaded item,
+    freeing resources and leaving the Loader empty.
+
+    \section2 Loader sizing behavior
+
+    Loader is like any other visual item and must be positioned and sized
+    accordingly to become visible.
+
+    \list
+    \o If an explicit size is not specified for the Loader, the Loader
+    is automatically resized to the size of the loaded item once the
+    component is loaded.
+    \o If the size of the Loader is specified explicitly by setting
+    the width, height or by anchoring, the loaded item will be resized
+    to the size of the Loader.
+    \endlist
+
+    In both scenarios the size of the item and the Loader are identical.
+    This ensures that anchoring to the Loader is equivalent to anchoring
+    to the loaded item.
+
+    \table
+    \row
+    \o sizeloader.qml
+    \o sizeitem.qml
+    \row
+    \o \snippet doc/src/snippets/declarative/loader/sizeloader.qml 0
+    \o \snippet doc/src/snippets/declarative/loader/sizeitem.qml 0
+    \row
+    \o The red rectangle will be sized to the size of the root item.
+    \o The red rectangle will be 50x50, centered in the root item.
+    \endtable
+
+
+    \section2 Receiving signals from loaded items
+
+    Any signals emitted from the loaded item can be received using the 
+    \l Connections element. For example, the following \c application.qml
+    loads \c MyItem.qml, and is able to receive the \c message signal from
+    the loaded item through a \l Connections object:
+
+    \table
+    \row 
+    \o application.qml
+    \o MyItem.qml
+    \row
+    \o \snippet doc/src/snippets/declarative/loader/connections.qml 0
+    \o \snippet doc/src/snippets/declarative/loader/MyItem.qml 0
+    \endtable
+
+    Alternatively, since \c MyItem.qml is loaded within the scope of the
+    Loader, it could also directly call any function defined in the Loader or
+    its parent \l Item.
+
+
+    \section2 Focus and key events
+
+    Loader is a focus scope. Its \l {Item::}{focus} property must be set to 
+    \c true for any of its children to get the \e {active focus}. (See 
+    \l{qmlfocus#Acquiring Focus and Focus Scopes}{the focus documentation page} 
+    for more details.) Any key events received in the loaded item should likely
+    also be \l {KeyEvent::}{accepted} so they are not propagated to the Loader.
+
+    For example, the following \c application.qml loads \c KeyReader.qml when
+    the \l MouseArea is clicked.  Notice the \l {Item::}{focus} property is 
+    set to \c true for the Loader as well as the \l Item in the dynamically 
+    loaded object:
+
+    \table
+    \row 
+    \o application.qml
+    \o KeyReader.qml
+    \row
+    \o \snippet doc/src/snippets/declarative/loader/focus.qml 0
+    \o \snippet doc/src/snippets/declarative/loader/KeyReader.qml 0
+    \endtable
+
+    Once \c KeyReader.qml is loaded, it accepts key events and sets 
+    \c event.accepted to \c true so that the event is not propagated to the
+    parent \l Rectangle.

+    \qmlproperty enumeration Loader::status
+
+    This property holds the status of QML loading.  It can be one of:
+    \list
+    \o Loader.Null - no QML source has been set
+    \o Loader.Ready - the QML source has been loaded
+    \o Loader.Loading - the QML source is currently being loaded
+    \o Loader.Error - an error occurred while loading the QML source
+    \endlist
+
+    Use this status to provide an update or respond to the status change in some way.
+    For example, you could:
+
+    \list
+    \o Trigger a state change:
+    \qml
+        State { name: 'loaded'; when: loader.status == Loader.Ready }
+    \endqml
+
+    \o Implement an \c onStatusChanged signal handler:
+    \qml
+        Loader {
+            id: loader
+            onStatusChanged: if (loader.status == Loader.Ready) console.log('Loaded')

+    \endqml
+
+    \o Bind to the status value:
+    \qml
+        Text { text: loader.status == Loader.Ready ? 'Loaded' : 'Not loaded' }
+    \endqml
+    \endlist
+
+    Note that if the source is a local file, the status will initially be Ready (or Error). While

+
+    A MouseArea is an invisible item that is typically used in conjunction with

+    By effectively acting as a proxy, the logic for mouse handling can be
+    contained within a MouseArea item.
+
+    For basic key handling, see the \l{Keys}{Keys attached property}.
+
+    The \l enabled property is used to enable and disable mouse handling for
+    the proxied item. When disabled, the mouse area becomes transparent to
+    mouse events.
+
+    The \l pressed read-only property indicates whether or not the user is
+    holding down a mouse button over the mouse area. This property is often
+    used in bindings between properties in a user interface. The containsMouse
+    read-only property indicates the presence of the mouse cursor over the
+    mouse area but, by default, only when a mouse button is held down; see below
+    for further details.
+
+    Information about the mouse position and button clicks are provided via
+    signals for which event handler properties are defined. The most commonly
+    used involved handling mouse presses and clicks: onClicked, onDoubleClicked,
+    onPressed, onReleased and onPressAndHold.
+
+    By default, MouseArea items only report mouse clicks and not changes to the
+    position of the mouse cursor. Setting the hoverEnabled property ensures that
+    handlers defined for onPositionChanged, onEntered and onExited are used and
+    that the containsMouse property is updated even when no mouse buttons are
+    pressed.

+    \enddiv
+
+    The following example uses a MouseArea in a \l Rectangle that changes
+    the \l Rectangle color to red when clicked:

+    \codeline
+    \snippet doc/src/snippets/declarative/mousearea/mousearea.qml intro
+
+    \clearfloat
+    Many MouseArea signals pass a \l{MouseEvent}{mouse} parameter that contains
+    additional information about the mouse event, such as the position, button,
+    and any key modifiers.
+
+    Here is an extension of the previous example that produces a different
+    color when the area is right clicked:

+    \c drag provides a convenient way to make an item draggable.
+
+    \list
+    \i \c drag.target specifies the id of the item to drag.
+    \i \c drag.active specifies if the target item is currently being dragged.
+    \i \c drag.axis specifies whether dragging can be done horizontally (\c Drag.XAxis), vertically (\c Drag.YAxis), or both (\c Drag.XandYAxis)
+    \i \c drag.minimum and \c drag.maximum limit how far the target can be dragged along the corresponding axes.
+    \endlist
+
+    The following example displays a \l Rectangle that can be dragged along the X-axis. The opacity
+    of the rectangle is reduced when it is dragged to the right.
+
+    \snippet doc/src/snippets/declarative/mousearea/mousearea.qml drag
+
+    \note Items cannot be dragged if they are anchored for the requested 
+    \c drag.axis. For example, if \c anchors.left or \c anchors.right was set
+    for \c rect in the above example, it cannot be dragged along the X-axis.
+    This can be avoided by settng the anchor value to \c undefined in 
+    an \l onPressed handler.
+
+    If \c drag.filterChildren is set to true, a drag can override descendant MouseAreas.  This
+    enables a parent MouseArea to handle drags, for example, while descendants handle clicks:

+    \class QDeclarativePaintedItem
+    \brief The QDeclarativePaintedItem class is an abstract base class for QDeclarativeView items that want cached painting.
+    \internal
+
+    This is a convenience class for implementing items that cache their painting.
+    The contents of the item are cached behind the scenes.
+    The dirtyCache() function should be called if the contents change to
+    ensure the cache is refreshed the next time painting occurs.
+
+    To subclass QDeclarativePaintedItem, you must reimplement drawContents() to draw
+    the contents of the item.
+*/

+    sub-classing QDeclarativePaintedItem this function should be implemented so as to
+    paint the contents of the item using the given \a painter for the
+    area of the contents specified by \a rect.

+
+    The PathAttribute object allows attributes consisting of a name and
+    a value to be specified for various points along a path.  The
+    attributes are exposed to the delegate as
+    \l{qdeclarativeintroduction.html#attached-properties} {Attached Properties}.
+    The value of an attribute at any particular point along the path is interpolated
+    from the PathAttributes bounding that point.
+
+    The example below shows a path with the items scaled to 30% with
+    opacity 50% at the top of the path and scaled 100% with opacity
+    100% at the bottom.  Note the use of the PathView.iconScale and

+    of the delegate.

+/*!
+    \qmlclass PathView QDeclarativePathView
+    \ingroup qml-view-elements
+    \since 4.7
+    \brief The PathView element lays out model-provided items on a path.
+    \inherits Item
+
+    A PathView displays data from models created from built-in QML elements like ListModel
+    and XmlListModel, or custom model classes defined in C++ that inherit from
+    QAbstractListModel.
+
+    The view has a \l model, which defines the data to be displayed, and
+    a \l delegate, which defines how the data should be displayed.  
+    The \l delegate is instantiated for each item on the \l path.
+    The items may be flicked to move them along the path.
+
+    For example, if there is a simple list model defined in a file \c ContactModel.qml like this:
+
+    \snippet doc/src/snippets/declarative/pathview/ContactModel.qml 0
+
+    This data can be represented as a PathView, like this:
+
+    \snippet doc/src/snippets/declarative/pathview/pathview.qml 0
+
+    \image pathview.gif
+
+    (Note the above example uses PathAttribute to scale and modify the
+    opacity of the items as they rotate. This additional code can be seen in the
+    PathAttribute documentation.)
+
+    PathView does not automatically handle keyboard navigation.  This is because
+    the keys to use for navigation will depend upon the shape of the path.  Navigation
+    can be added quite simply by setting \c focus to \c true and calling
+    \l decrementCurrentIndex() or \l incrementCurrentIndex(), for example to navigate
+    using the left and right arrow keys:
+
+    \qml
+    PathView {
+        // ...
+        focus: true
+        Keys.onLeftPressed: decrementCurrentIndex()
+        Keys.onRightPressed: incrementCurrentIndex()
+    }
+    \endqml
+
+    The path view itself is a focus scope (see \l{qmlfocus#Acquiring Focus and Focus Scopes}{the focus documentation page} for more details).
+
+    Delegates are instantiated as needed and may be destroyed at any time.
+    State should \e never be stored in a delegate.
+
+    PathView attaches a number of properties to the root item of the delegate, for example
+    \c {PathView.isCurrentItem}.  In the following example, the root delegate item can access
+    this attached property directly as \c PathView.isCurrentItem, while the child
+    \c nameText object must refer to this property as \c wrapper.PathView.isCurrentItem.
+
+    \snippet doc/src/snippets/declarative/pathview/pathview.qml 1
+
+    \bold Note that views do not enable \e clip automatically.  If the view
+    is not clipped by another item or the screen, it will be necessary
+    to set \e {clip: true} in order to have the out of view items clipped

+    \brief The QDeclarativeBasePositioner class provides a base for QDeclarativeGraphics layouts.
+
+    To create a QDeclarativeGraphics Positioner, simply subclass QDeclarativeBasePositioner and implement
+    doLayout(), which is automatically called when the layout might need
+    updating. In doLayout() use the setX and setY functions from QDeclarativeBasePositioner, and the
+    base class will apply the positions along with the appropriate transitions. The items to
+    position are provided in order as the protected member positionedItems.
+
+    You also need to set a PositionerType, to declare whether you are positioning the x, y or both
+    for the child items. Depending on the chosen type, only x or y changes will be applied.
+
+    Note that the subclass is responsible for adding the spacing in between items.

+  \brief The Grid item positions its children in a grid.
+  \inherits Item
+
+  The Grid item positions its child items so that they are
+  aligned in a grid and are not overlapping. 
+
+  The grid positioner calculates a grid of rectangular cells of sufficient
+  size to hold all items, placing the items in the cells, from left to right
+  and top to bottom. Each item is positioned in the top-left corner of its
+  cell with position (0, 0).
+
+  A Grid defaults to four columns, and as many rows as are necessary to
+  fit all child items. The number of rows and columns can be constrained
+  by setting the \l rows and \l columns properties.
+
+  Spacing can be added between child items by setting the \l spacing
+  property. The amount of spacing applied will be the same in the
+  horizontal and vertical directions.
+
+  See \l{Using QML Positioner and Repeater Items} for more details about this item and other
+  related items.
+
+  \section1 Example Usage
+
+  The following example demonstrates this.
+
+  \image gridLayout_example.png
+
+  \snippet doc/src/snippets/declarative/grid/grid.qml document
+
+  \section1 Using Transitions
+
+  Transitions can be used to animate items that are added to, moved within,
+  or removed from a Grid item. The \l add and \l move properties can be set to
+  the transitions that will be applied when items are added to, removed from,
+  or re-positioned within a Grid item.
+
+  \section1 Limitations
+
+  Note that the positioner assumes that the x and y positions of its children
+  will not change. If you manually change the x or y properties in script, bind
+  the x or y properties, use anchors on a child of a positioner, or have the
+  width or height of a child depend on the position of a child, then the
+  positioner may exhibit strange behaviour. If you need to perform any of these
+  actions, consider positioning the items without the use of a Grid.
+
+  Items with a width or height of 0 will not be positioned.

+  \brief The Flow item arranges its children side by side, wrapping as necessary.
+  \inherits Item
+
+  The Flow item positions its child items like words on a page, wrapping them
+  to create rows or columns of items that do not overlap.
+
+  Spacing between items can be added using the \l spacing property.
+  Transitions can be used for cases where items managed by a Column are
+  added or moved. These are stored in the \l add and \l move properties
+  respectively.
+
+  See \l{Using QML Positioner and Repeater Items} for more details about this item and other
+  related items.
+
+  \section1 Example Usage
+
+  The following example positions \l Text items within a parent item using
+  a Flow item.
+
+  \image qml-flow-snippet.png
+
+  \snippet doc/src/snippets/declarative/flow.qml flow item
+
+  \section1 Using Transitions
+
+  Transitions can be used to animate items that are added to, moved within,
+  or removed from a Flow item. The \l add and \l move properties can be set to
+  the transitions that will be applied when items are added to, removed from,
+  or re-positioned within a Flow item.
+
+  The use of transitions with positioners is described in more detail in the
+  \l{Using QML Positioner and Repeater Items#Using Transitions}{Using QML
+  Positioner and Repeater Items} document.
+
+  \section1 Limitations
+
+  Note that the positioner assumes that the x and y positions of its children
+  will not change. If you manually change the x or y properties in script, bind
+  the x or y properties, use anchors on a child of a positioner, or have the
+  width or height of a child depend on the position of a child, then the
+  positioner may exhibit strange behaviour.  If you need to perform any of these
+  actions, consider positioning the items without the use of a Flow.
+
+  Items with a width or height of 0 will not be positioned.

+/*!
+    \qmlproperty Transition Flow::add
+
+    This property holds the transition to be applied when adding an
+    item to the positioner. The transition will only be applied to the
+    added item(s).  Positioner transitions will only affect the
+    position (x, y) of items.
+
+    For a positioner, adding an item can mean that either the object
+    has been created or reparented, and thus is now a child or the
+    positioner, or that the object has had its opacity increased from
+    zero, and thus is now visible.

+    \brief The Gradient item defines a gradient fill.
+
+    A gradient is defined by two or more colors, which will be blended seamlessly.
+
+    The colors are specified as a set of GradientStop child items, each of
+    which defines a position on the gradient from 0.0 to 1.0 and a color.
+    The position of each GradientStop is defined by setting its
+    \l{GradientStop::}{position} property; its color is defined using its
+    \l{GradientStop::}{color} property.
+
+    A gradient without any gradient stops is rendered as a solid white fill.
+
+    Note that this item is not a visual representation of a gradient. To display a
+    gradient, use a visual element (like \l Rectangle) which supports the use
+    of gradients.

+
+    \clearfloat
+    \section1 Performance and Limitations
+
+    Calculating gradients can be computationally expensive compared to the use
+    of solid color fills or images. Consider using gradients for static items
+    in a user interface.
+
+    In Qt 4.7, only vertical, linear gradients can be applied to items. If you
+    need to apply different orientations of gradients, a combination of rotation
+    and clipping will need to be applied to the relevant items. This can
+    introduce additional performance requirements for your application.
+
+    The use of animations involving gradient stops may not give the desired
+    result. An alternative way to animate gradients is to use pre-generated
+    images or SVG drawings containing gradients.

+    \brief The Rectangle item provides a filled rectangle with an optional border.
+    \inherits Item
+
+    Rectangle items are used to fill areas with solid color or gradients, and are
+    often used to hold other items.
+
+    \section1 Appearance
+
+    Each Rectangle item is painted using either a solid fill color, specified using
+    the \l color property, or a gradient, defined using a Gradient element and set
+    using the \l gradient property. If both a color and a gradient are specified,
+    the gradient is used.
+
+    You can add an optional border to a rectangle with its own color and thickness
+    by settting the \l border.color and \l border.width properties.
+
+    You can also create rounded rectangles using the \l radius property. Since this
+    introduces curved edges to the corners of a rectangle, it may be appropriate to
+    set the \l smooth property to improve its appearance.

+
+    \clearfloat
+    \section1 Performance
+
+    Using the \l smooth property improves the appearance of a rounded rectangle at
+    the cost of rendering performance. You should consider unsetting this property
+    for rectangles in motion, and only set it when they are stationary.

+    rectangle itself or its position relative to other items if anchors are used.
+
+    If \c border.width is an odd number, the rectangle is painted at a half-pixel offset to retain
+    border smoothness. Also, the border is rendered evenly on either side of the
+    rectangle's boundaries, and the spare pixel is rendered to the right and below the
+    rectangle (as documented for QRect rendering). This can cause unintended effects if

+    \qmlclass Repeater QDeclarativeRepeater
+    \ingroup qml-utility-elements
+    \since 4.7
+    \inherits Item
+
+    \brief The Repeater element allows you to repeat an Item-based component using a model.
+
+    The Repeater element is used to create a large number of
+    similar items. Like other view elements, a Repeater has a \l model and a \l delegate:
+    for each entry in the model, the delegate is instantiated
+    in a context seeded with data from the model. A Repeater item is usually
+    enclosed in a positioner element such as \l Row or \l Column to visually
+    position the multiple delegate items created by the Repeater.
+
+    The following Repeater creates three instances of a \l Rectangle item within
+    a \l Row:
+
+    \snippet doc/src/snippets/declarative/repeaters/repeater.qml import
+    \codeline
+    \snippet doc/src/snippets/declarative/repeaters/repeater.qml simple
+
+    \image repeater-simple.png
+
+    A Repeater's \l model can be any of the supported \l {qmlmodels}{data models}.
+    Additionally, like delegates for other views, a Repeater delegate can access
+    its index within the repeater, as well as the model data relevant to the
+    delegate. See the \l delegate property documentation for details.
+
+    Items instantiated by the Repeater are inserted, in order, as
+    children of the Repeater's parent.  The insertion starts immediately after
+    the repeater's position in its parent stacking list.  This allows
+    a Repeater to be used inside a layout. For example, the following Repeater's
+    items are stacked between a red rectangle and a blue rectangle:
+
+    \snippet doc/src/snippets/declarative/repeaters/repeater.qml layout
+
+    \image repeater.png
+
+
+    \note A Repeater item owns all items it instantiates. Removing or dynamically destroying
+    an item created by a Repeater results in unpredictable behavior.
+
+
+    \section2 Considerations when using Repeater
+
+    The Repeater element creates all of its delegate items when the repeater is first
+    created. This can be inefficient if there are a large number of delegate items and
+    not all of the items are required to be visible at the same time. If this is the case,
+    consider using other view elements like ListView (which only creates delegate items 
+    when they are scrolled into view) or use the \l {Dynamic Object Creation} methods to 
+    create items as they are required.
+
+    Also, note that Repeater is \l {Item}-based, and can only repeat \l {Item}-derived objects. 
+    For example, it cannot be used to repeat QtObjects:
+    \badcode
+    Item {
+        //XXX does not work! Can't repeat QtObject as it doesn't derive from Item.
+        Repeater {
+            model: 10
+            QtObject {}
+        }
+    }
+    \endcode
+ */
+
+/*!
+    \qmlsignal Repeater::onItemAdded(int index, Item item)
+    \since Quick 1.1
+
+    This handler is called when an item is added to the repeater. The \a index
+    parameter holds the index at which the item has been inserted within the

+    \qmlproperty Component Repeater::delegate
+    \default
+
+    The delegate provides a template defining each item instantiated by the repeater.
+
+    Delegates are exposed to a read-only \c index property that indicates the index
+    of the delegate within the repeater. For example, the following \l Text delegate
+    displays the index of each repeated item:
+
+    \table
+    \row
+    \o \snippet doc/src/snippets/declarative/repeaters/repeater.qml index
+    \o \image repeater-index.png
+    \endtable
+
+    If the \l model is a \l{QStringList-based model}{string list} or
+    \l{QObjectList-based model}{object list}, the delegate is also exposed to
+    a read-only \c modelData property that holds the string or object data. For
+    example:
+
+    \table
+    \row
+    \o \snippet doc/src/snippets/declarative/repeaters/repeater.qml modeldata
+    \o \image repeater-modeldata.png
+    \endtable
+
+    If the \l model is a model object (such as a \l ListModel) the delegate
+    can access all model roles as named properties, in the same way that delegates
+    do for view classes like ListView.

+    \inherits Item
+
+    Text items can display both plain and rich text. For example, red text with
+    a specific font and size can be defined like this:
+
+    \qml
+    Text {
+        text: "Hello World!"
+        font.family: "Helvetica"
+        font.pointSize: 24
+        color: "red"
+    }
+    \endqml
+
+    Rich text is defined using HTML-style markup:
+
+    \qml
+    Text {
+        text: "<b>Hello</b> <i>World!</i>"
+    }
+    \endqml
+
+    \image declarative-text.png
+
+    If height and width are not explicitly set, Text will attempt to determine how
+    much room is needed and set it accordingly. Unless \l wrapMode is set, it will always
+    prefer width to height (all text will be placed on a single line).
+
+    The \l elide property can alternatively be used to fit a single line of
+    plain text to a set width.
+
+    Note that the \l{Supported HTML Subset} is limited. Also, if the text contains
+    HTML img tags that load remote images, the text is reloaded.
+
+    Text provides read-only text. For editable text, see \l TextEdit.

+    \qmlclass TextEdit QDeclarativeTextEdit
+    \ingroup qml-basic-visual-elements
+    \since 4.7
+    \brief The TextEdit item displays multiple lines of editable formatted text.
+    \inherits Item
+
+    The TextEdit item displays a block of editable, formatted text.
+
+    It can display both plain and rich text. For example:
+
+    \qml
+TextEdit {
+    width: 240
+    text: "<b>Hello</b> <i>World!</i>"
+    font.family: "Helvetica"
+    font.pointSize: 20
+    color: "blue"
+    focus: true
+}
+    \endqml
+
+    \image declarative-textedit.gif
+
+    Setting \l {Item::focus}{focus} to \c true enables the TextEdit item to receive keyboard focus.
+
+    Note that the TextEdit does not implement scrolling, following the cursor, or other behaviors specific
+    to a look-and-feel. For example, to add flickable scrolling that follows the cursor:
+
+    \snippet snippets/declarative/texteditor.qml 0
+
+    A particular look-and-feel might use smooth scrolling (eg. using SmoothedFollow), might have a visible
+    scrollbar, or a scrollbar that fades in to show location, etc.
+
+    Clipboard support is provided by the cut(), copy(), and paste() functions, and the selection can
+    be handled in a traditional "mouse" mechanism by setting selectByMouse, or handled completely
+    from QML by manipulating selectionStart and selectionEnd, or using selectAll() or selectWord().
+
+    You can translate between cursor positions (characters from the start of the document) and pixel
+    points using positionAt() and positionToRectangle().

+    \brief The TextInput item displays an editable line of text.
+    \inherits Item
+
+    The TextInput element displays a single line of editable plain text.
+
+    TextInput is used to accept a line of text input. Input constraints
+    can be placed on a TextInput item (for example, through a \l validator or \l inputMask),
+    and setting \l echoMode to an appropriate value enables TextInput to be used for
+    a password input field.
+
+    On Mac OS X, the Up/Down key bindings for Home/End are explicitly disabled.
+    If you want such bindings (on any platform), you will need to construct them in QML.

+    text range.

+    \o TextEdit.SelectCharacters - Sets either the selectionStart or selectionEnd (whichever was at

+        moveCursorSelection(7, TextInput.SelectCharacters)

+    and then retract the selection end from 9 to 7, leaving the text from position 5 to 7
+    selected (the 6th and 7th characters).

+\class QDeclarativeTextLayout
+\brief The QDeclarativeTextLayout class is a version of QStaticText that works with QTextLayouts.
+\internal
+
+This class is basically a copy of the QStaticText code, but it is adapted to source its text from
+QTextLayout.
+
+It is also considerably faster to create a QDeclarativeTextLayout than a QStaticText because it uses 
+a single, shared QPainter instance.  QStaticText by comparison creates a new QPainter per instance.
+As a consequence this means that QDeclarativeTextLayout is not re-enterant.  Adding a lock around 
+the shared painter solves this, and only introduces a minor performance penalty, but is unnecessary 
+for QDeclarativeTextLayout's current use (QDeclarativeText is already tied to the GUI thread).

+    \brief The VisualItemModel allows items to be provided to a view.
+
+    A VisualItemModel contains the visual items to be used in a view.
+    When a VisualItemModel is used in a view, the view does not require
+    a delegate since the VisualItemModel already contains the visual
+    delegate (items).
+
+    An item can determine its index within the
+    model via the \l{VisualItemModel::index}{index} attached property.
+
+    The example below places three colored rectangles in a ListView.
+    \code
+    import QtQuick 1.0
+
+    Rectangle {
+        VisualItemModel {

+            Rectangle { height: 30; width: 80; color: "green" }

+    \class QDeclarativeComponent
+    \since 4.7
+    \brief The QDeclarativeComponent class encapsulates a QML component definition.
+    \mainclass
+
+    Components are reusable, encapsulated QML elements with well-defined interfaces.
+    They are often defined in \l {qdeclarativedocuments.html}{Component Files}.
+
+    A QDeclarativeComponent instance can be created from a QML file.
+    For example, if there is a \c main.qml file like this:
+
+    \qml
+    import QtQuick 1.0
+
+    Item {
+        width: 200
+        height: 200
+    }
+    \endqml
+
+    The following code loads this QML file as a component, creates an instance of
+    this component using create(), and then queries the \l Item's \l {Item::}{width}
+    value:
+
+    \code
+    QDeclarativeEngine *engine = new QDeclarativeEngine;
+    QDeclarativeComponent component(engine, QUrl::fromLocalFile("main.qml"));
+
+    QObject *myObject = component.create();
+    QDeclarativeItem *item = qobject_cast<QDeclarativeItem*>(myObject);
+    int width = item->width();  // width = 200
+    \endcode
+
+
+    \section2 Network Components
+
+    If the URL passed to QDeclarativeComponent is a network resource, or if the QML document references a
+    network resource, the QDeclarativeComponent has to fetch the network data before it is able to create
+    objects.  In this case, the QDeclarativeComponent will have a \l {QDeclarativeComponent::Loading}{Loading}
+    \l {QDeclarativeComponent::status()}{status}.  An application will have to wait until the component
+    is \l {QDeclarativeComponent::Ready}{Ready} before calling \l {QDeclarativeComponent::create()}.
+
+    The following example shows how to load a QML file from a network resource.  After creating
+    the QDeclarativeComponent, it tests whether the component is loading.  If it is, it connects to the
+    QDeclarativeComponent::statusChanged() signal and otherwise calls the \c {continueLoading()} method
+    directly. Note that QDeclarativeComponent::isLoading() may be false for a network component if the
+    component has been cached and is ready immediately.
+
+    \code
+    MyApplication::MyApplication()
+    {
+        // ...
+        component = new QDeclarativeComponent(engine, QUrl("http://www.example.com/main.qml"));
+        if (component->isLoading())
+            QObject::connect(component, SIGNAL(statusChanged(QDeclarativeComponent::Status)),
+                             this, SLOT(continueLoading()));
+        else
+            continueLoading();
+    }
+
+    void MyApplication::continueLoading()
+    {
+        if (component->isError()) {
+            qWarning() << component->errors();
+        } else {
+            QObject *myObject = component->create();
+        }
+    }
+    \endcode

+    \qmlclass Component QDeclarativeComponent
+    \ingroup qml-utility-elements
+    \since 4.7
+    \brief The Component element encapsulates a QML component definition.
+
+    Components are reusable, encapsulated QML elements with well-defined interfaces.
+
+    Components are often defined by \l {qdeclarativedocuments.html}{component files} -
+    that is, \c .qml files. The \e Component element essentially allows QML components
+    to be defined inline, within a \l {QML Document}{QML document}, rather than as a separate QML file.
+    This may be useful for reusing a small component within a QML file, or for defining
+    a component that logically belongs with other QML components within a file.
+
+    For example, here is a component that is used by multiple \l Loader objects.
+    It contains a single item, a \l Rectangle:
+
+    \snippet doc/src/snippets/declarative/component.qml 0
+
+    Notice that while a \l Rectangle by itself would be automatically 
+    rendered and displayed, this is not the case for the above rectangle
+    because it is defined inside a \c Component. The component encapsulates the
+    QML elements within, as if they were defined in a separate QML
+    file, and is not loaded until requested (in this case, by the
+    two \l Loader objects).
+
+    Defining a \c Component is similar to defining a \l {QML Document}{QML document}.
+    A QML document has a single top-level item that defines the behaviors and
+    properties of that component, and cannot define properties or behaviors outside
+    of that top-level item. In the same way, a \c Component definition contains a single
+    top level item (which in the above example is a \l Rectangle) and cannot define any
+    data outside of this item, with the exception of an \e id (which in the above example
+    is \e redSquare).
+
+    The \c Component element is commonly used to provide graphical components
+    for views. For example, the ListView::delegate property requires a \c Component
+    to specify how each list item is to be displayed.
+
+    \c Component objects can also be created dynamically using
+    \l{QML:Qt::createComponent()}{Qt.createComponent()}.

+    \qmlmethod object Component::createObject(Item parent, object properties)
+
+    Creates and returns an object instance of this component that will have
+    the given \a parent and \a properties. The \a properties argument is optional.
+    Returns null if object creation fails.
+
+    The object will be created in the same context as the one in which the component
+    was created. This function will always return null when called on components
+    which were not created in QML.
+
+    If you wish to create an object without setting a parent, specify \c null for
+    the \a parent value. Note that if the returned object is to be displayed, you 
+    must provide a valid \a parent value or set the returned object's \l{Item::parent}{parent} 
+    property, or else the object will not be visible.
+
+    If a \a parent is not provided to createObject(), a reference to the returned object must be held so that
+    it is not destroyed by the garbage collector.  This is true regardless of whether \l{Item::parent} is set afterwards,
+    since setting the Item parent does not change object ownership; only the graphical parent is changed.
+
+    As of QtQuick 1.1, this method accepts an optional \a properties argument that specifies a
+    map of initial property values for the created object. These values are applied before object
+    creation is finalized. (This is more efficient than setting property values after object creation,
+    particularly where large sets of property values are defined, and also allows property bindings
+    to be set up before the object is created.)
+
+    The \a properties argument is specified as a map of property-value items. For example, the code
+    below creates an object with initial \c x and \c y values of 100 and 200, respectively:
+
+    \js
+        var component = Qt.createComponent("Button.qml");
+        if (component.status == Component.Ready)
+            component.createObject(parent, {"x": 100, "y": 100});
+    \endjs
+
+    Dynamically created instances can be deleted with the \c destroy() method.
+    See \l {Dynamic Object Management in QML} for more information.

+/*!
+    \class QDeclarativeContext
+    \since 4.7
+    \brief The QDeclarativeContext class defines a context within a QML engine.
+    \mainclass
+
+    Contexts allow data to be exposed to the QML components instantiated by the
+    QML engine.
+
+    Each QDeclarativeContext contains a set of properties, distinct from its QObject
+    properties, that allow data to be explicitly bound to a context by name.  The
+    context properties are defined and updated by calling
+    QDeclarativeContext::setContextProperty().  The following example shows a Qt model
+    being bound to a context and then accessed from a QML file.
+
+    \code
+    QDeclarativeEngine engine;
+    QStringListModel modelData;
+    QDeclarativeContext *context = new QDeclarativeContext(engine.rootContext());
+    context->setContextProperty("myModel", &modelData);
+
+    QDeclarativeComponent component(&engine);
+    component.setData("import QtQuick 1.0\nListView { model: myModel }", QUrl());
+    QObject *window = component.create(context);
+    \endcode
+
+    Note it is the responsibility of the creator to delete any QDeclarativeContext it
+    constructs. If the \c context object in the example is no longer needed when the
+    \c window component instance is destroyed, the \c context must be destroyed explicitly.
+    The simplest way to ensure this is to set \c window as the parent of \c context.
+
+    To simplify binding and maintaining larger data sets, a context object can be set
+    on a QDeclarativeContext.  All the properties of the context object are available
+    by name in the context, as though they were all individually added through calls
+    to QDeclarativeContext::setContextProperty().  Changes to the property's values are
+    detected through the property's notify signal.  Setting a context object is both
+    faster and easier than manually adding and maintaing context property values.
+
+    The following example has the same effect as the previous one, but it uses a context
+    object.
+
+    \code
+    class MyDataSet : ... {
+        ...
+        Q_PROPERTY(QAbstractItemModel *myModel READ model NOTIFY modelChanged)
+        ...
+    };
+
+    MyDataSet myDataSet;
+    QDeclarativeEngine engine;
+    QDeclarativeContext *context = new QDeclarativeContext(engine.rootContext());
+    context->setContextObject(&myDataSet);
+
+    QDeclarativeComponent component(&engine);
+    component.setData("import QtQuick 1.0\nListView { model: myModel }", QUrl());
+    component.create(context);
+    \endcode
+
+    All properties added explicitly by QDeclarativeContext::setContextProperty() take
+    precedence over the context object's properties.
+
+    \section2 The Context Hierarchy
+
+    Contexts form a hierarchy. The root of this hierarchy is the QML engine's
+    \l {QDeclarativeEngine::rootContext()}{root context}. Child contexts inherit
+    the context properties of their parents; if a child context sets a context property
+    that already exists in its parent, the new context property overrides that of the
+    parent.
+
+    The following example defines two contexts - \c context1 and \c context2.  The
+    second context overrides the "b" context property inherited from the first with a
+    new value.
+
+    \code
+    QDeclarativeEngine engine;
+    QDeclarativeContext *context1 = new QDeclarativeContext(engine.rootContext());
+    QDeclarativeContext *context2 = new QDeclarativeContext(context1);
+
+    context1->setContextProperty("a", 12);
+    context1->setContextProperty("b", 12);
+
+    context2->setContextProperty("b", 15);
+    \endcode
+
+    While QML objects instantiated in a context are not strictly owned by that
+    context, their bindings are.  If a context is destroyed, the property bindings of
+    outstanding QML objects will stop evaluating.
+
+    \warning Setting the context object or adding new context properties after an object
+    has been created in that context is an expensive operation (essentially forcing all bindings
+    to reevaluate). Thus whenever possible you should complete "setup" of the context
+    before using it to create any objects.

+    \class QDeclarativeCustomParser
+    \brief The QDeclarativeCustomParser class allows you to add new arbitrary types to QML.
+    \internal
+
+    By subclassing QDeclarativeCustomParser, you can add a parser for
+    building a particular type.
+
+    The subclass must implement compile() and setCustomData(), and register
+    itself in the meta type system by calling the macro:
+
+    \code
+    QML_REGISTER_CUSTOM_TYPE(Module, MajorVersion, MinorVersion, Name, TypeClass, ParserClass)
+    \endcode
+*/
+
+/*
+    \fn QByteArray QDeclarativeCustomParser::compile(const QList<QDeclarativeCustomParserProperty> & properties)
+
+    The custom parser processes \a properties, and returns
+    a QByteArray containing data meaningful only to the
+    custom parser; the type engine will pass this same data to
+    setCustomData() when making an instance of the data.
+
+    Errors must be reported via the error() functions.
+
+    The QByteArray may be cached between executions of the system, so
+    it must contain correctly-serialized data (not, for example,
+    pointers to stack objects).
+*/
+
+/*
+    \fn void QDeclarativeCustomParser::setCustomData(QObject *object, const QByteArray &data)
+
+    This function sets \a object to have the properties defined
+    by \a data, which is a block of data previously returned by a call
+    to compile().
+
+    Errors should be reported using qmlInfo(object).
+
+    The \a object will be an instance of the TypeClass specified by QML_REGISTER_CUSTOM_TYPE.

+
+\keyword QmlGlobalQtObject
+
+\brief The \c Qt object provides useful enums and functions from Qt, for use in all QML files. 
+
+The \c Qt object is a global object with utility functions, properties and enums.
+
+It is not instantiable; to use it, call the members of the global \c Qt object directly.
+For example:
+
+\qml
+import QtQuick 1.0
+
+Text {
+    color: Qt.rgba(1, 0, 0, 1)
+    text: Qt.md5("hello, world")
+}
+\endqml
+
+
+\section1 Enums
+
+The Qt object contains the enums available in the \l {Qt Namespace}. For example, you can access
+the \l Qt::LeftButton and \l Qt::RightButton enum values as \c Qt.LeftButton and \c Qt.RightButton.
+
+
+\section1 Types
+The Qt object also contains helper functions for creating objects of specific
+data types. This is primarily useful when setting the properties of an item
+when the property has one of the following types:
+
+\list
+\o \c color - use \l{QML:Qt::rgba()}{Qt.rgba()}, \l{QML:Qt::hsla()}{Qt.hsla()}, \l{QML:Qt::darker()}{Qt.darker()}, \l{QML:Qt::lighter()}{Qt.lighter()} or \l{QML:Qt::tint()}{Qt.tint()}
+\o \c rect - use \l{QML:Qt::rect()}{Qt.rect()}
+\o \c point - use \l{QML:Qt::point()}{Qt.point()}
+\o \c size - use \l{QML:Qt::size()}{Qt.size()}
+\o \c vector3d - use \l{QML:Qt::vector3d()}{Qt.vector3d()}
+\endlist
+
+There are also string based constructors for these types. See \l{qdeclarativebasictypes.html}{QML Basic Types} for more information.
+
+\section1 Date/Time Formatters
+
+The Qt object contains several functions for formatting QDateTime, QDate and QTime values.
+
+\list
+    \o \l{QML:Qt::formatDateTime}{string Qt.formatDateTime(datetime date, variant format)}
+    \o \l{QML:Qt::formatDate}{string Qt.formatDate(datetime date, variant format)}
+    \o \l{QML:Qt::formatTime}{string Qt.formatTime(datetime date, variant format)}
+\endlist
+
+The format specification is described at \l{QML:Qt::formatDateTime}{Qt.formatDateTime}.
+
+
+\section1 Dynamic Object Creation
+The following functions on the global object allow you to dynamically create QML
+items from files or strings. See \l{Dynamic Object Management in QML} for an overview
+of their use.
+
+\list
+    \o \l{QML:Qt::createComponent()}{object Qt.createComponent(url)}
+    \o \l{QML:Qt::createQmlObject()}{object Qt.createQmlObject(string qml, object parent, string filepath)}
+\endlist

+/*!
+    \qmlproperty object QML:Qt::application
+    \since QtQuick 1.1
+
+    The \c application object provides access to global application state
+    properties shared by many QML components.
+
+    Its properties are:
+
+    \table
+    \row
+    \o \c application.active
+    \o
+    This read-only property indicates whether the application is the top-most and focused
+    application, and the user is able to interact with the application. The property
+    is false when the application is in the background, the device keylock or screen
+    saver is active, the screen backlight is turned off, or the global system dialog
+    is being displayed on top of the application. It can be used for stopping and
+    pausing animations, timers and active processing of data in order to save device
+    battery power and free device memory and processor load when the application is not
+    active.
+
+    \row
+    \o \c application.layoutDirection
+    \o
+    This read-only property can be used to query the default layout direction of the
+    application. On system start-up, the default layout direction depends on the
+    application's language. The property has a value of \c Qt.RightToLeft in locales
+    where text and graphic elements are read from right to left, and \c Qt.LeftToRight
+    where the reading direction flows from left to right. You can bind to this
+    property to customize your application layouts to support both layout directions.
+
+    Possible values are:
+
+    \list
+    \o Qt.LeftToRight - Text and graphics elements should be positioned
+                        from left to right.
+    \o Qt.RightToLeft - Text and graphics elements should be positioned
+                        from right to left.
+    \endlist
+    \endtable

+    The following example uses the \c application object to indicate
+    whether the application is currently active:

+  \brief The QDeclarativeEngine class provides an environment for instantiating QML components.
+  \mainclass
+
+  Each QML component is instantiated in a QDeclarativeContext.
+  QDeclarativeContext's are essential for passing data to QML
+  components.  In QML, contexts are arranged hierarchically and this
+  hierarchy is managed by the QDeclarativeEngine.
+
+  Prior to creating any QML components, an application must have
+  created a QDeclarativeEngine to gain access to a QML context.  The
+  following example shows how to create a simple Text item.
+
+  \code
+  QDeclarativeEngine engine;
+  QDeclarativeComponent component(&engine);
+  component.setData("import QtQuick 1.0\nText { text: \"Hello world!\" }", QUrl());
+  QDeclarativeItem *item = qobject_cast<QDeclarativeItem *>(component.create());
+
+  //add item to view, etc
+  ...
+  \endcode
+
+  In this case, the Text item will be created in the engine's
+  \l {QDeclarativeEngine::rootContext()}{root context}.

+  used on objects with CppOwnership.  This option is similar to

+  call or property access, QML will delete the object if there are no

+  QObject::parent().  This option is similar to
+  QScriptEngine::ScriptOwnership.
+
+  Generally an application doesn't need to set an object's ownership
+  explicitly.  QML uses a heuristic to set the default object
+  ownership.  By default, an object that is created by QML has
+  JavaScriptOwnership.  The exception to this are the root objects
+  created by calling QDeclarativeCompnent::create() or
+  QDeclarativeComponent::beginCreate() which have CppOwnership by
+  default.  The ownership of these root-level objects is considered to
+  have been transferred to the C++ caller.
+
+  Objects not-created by QML have CppOwnership by default.  The
+  exception to this is objects returned from a C++ method call.  The

+    \class QDeclarativeError
+    \since 4.7
+    \brief The QDeclarativeError class encapsulates a QML error.
+
+    QDeclarativeError includes a textual description of the error, as well
+    as location information (the file, line, and column). The toString()
+    method creates a single-line, human-readable string containing all of
+    this information, for example:
+    \code
+    file:///home/user/test.qml:7:8: Invalid property assignment: double expected
+    \endcode
+
+    You can use qDebug() or qWarning() to output errors to the console. This method
+    will attempt to open the file indicated by the error
+    and include additional contextual information.
+    \code
+    file:///home/user/test.qml:7:8: Invalid property assignment: double expected
+            y: "hello"
+               ^

+/*!
+    \since 4.7
+    \class QDeclarativeExtensionPlugin
+    \brief The QDeclarativeExtensionPlugin class provides an abstract base for custom QML extension plugins.
+
+    \ingroup plugins
+
+    QDeclarativeExtensionPlugin is a plugin interface that makes it possible to
+    create QML extensions that can be loaded dynamically into QML applications.
+    These extensions allow custom QML types to be made available to the QML engine. 
+    
+    To write a QML extension plugin:
+    
+    \list
+    \o Subclass QDeclarativeExtensionPlugin, implement registerTypes() method
+    to register types using qmlRegisterType(), and export the class using the Q_EXPORT_PLUGIN2() macro
+    \o Write an appropriate project file for the plugin
+    \o Create a \l{Writing a qmldir file}{qmldir file} to describe the plugin
+    \endlist
+
+    QML extension plugins can be used to provide either application-specific or
+    library-like plugins. Library plugins should limit themselves to registering types,
+    as any manipulation of the engine's root context may cause conflicts
+    or other issues in the library user's code.
+
+
+    \section1 An example
+
+    Suppose there is a new \c TimeModel C++ class that should be made available
+    as a new QML element. It provides the current time through \c hour and \c minute 
+    properties, like this:
+
+    \snippet examples/declarative/cppextensions/plugins/plugin.cpp 0
+    \dots
+
+    To make this class available as a QML type, create a plugin that registers
+    this type with a specific \l {QML Modules}{module} using qmlRegisterType(). For this example the plugin
+    module will be named \c com.nokia.TimeExample (as defined in the project
+    file further below).
+
+    \snippet examples/declarative/cppextensions/plugins/plugin.cpp plugin
+    \codeline
+    \snippet examples/declarative/cppextensions/plugins/plugin.cpp export
+
+    This registers the \c TimeModel class with the 1.0 version of this 
+    plugin library, as a QML type called \c Time. The Q_ASSERT statement 
+    ensures the module is imported correctly by any QML components that use this plugin.
+
+    The project file defines the project as a plugin library and specifies 
+    it should be built into the \c com/nokia/TimeExample directory:
+
+    \code
+    TEMPLATE = lib
+    CONFIG += qt plugin
+    QT += declarative
+
+    DESTDIR = com/nokia/TimeExample
+    TARGET = qmlqtimeexampleplugin
+    ...
+    \endcode    
+
+    Finally, a \l{Writing a qmldir file}{qmldir file} is required in the \c com/nokia/TimeExample directory
+    that describes the plugin. This directory includes a \c Clock.qml file that
+    should be bundled with the plugin, so it needs to be specified in the \c qmldir
+    file:
+
+    \quotefile examples/declarative/cppextensions/plugins/com/nokia/TimeExample/qmldir
+
+    Once the project is built and installed, the new \c Time element can be 
+    used by any QML component that imports the \c com.nokia.TimeExample module:
+
+    \snippet examples/declarative/cppextensions/plugins/plugins.qml 0
+
+    The full source code is available in the \l {declarative/cppextensions/plugins}{plugins example}.
+
+    The \l {Tutorial: Writing QML extensions with C++} also contains a chapter
+    on creating QML plugins.
+
+    \sa QDeclarativeEngine::importPlugin(), {How to Create Qt Plugins}
+*/
+
+/*!
+    \fn void QDeclarativeExtensionPlugin::registerTypes(const char *uri)
+
+    Registers the QML types in the given \a uri. Subclasses should implement
+    this to call qmlRegisterType() for all types which are provided by the extension

+    based on the name and path of the extension's plugin library.

+/*!
+    \class QDeclarativeImageProvider
+    \since 4.7
+    \brief The QDeclarativeImageProvider class provides an interface for supporting pixmaps and threaded image requests in QML.
+
+    QDeclarativeImageProvider is used to provide advanced image loading features
+    in QML applications. It allows images in QML to be:
+
+    \list
+    \o Loaded using QPixmaps rather than actual image files
+    \o Loaded asynchronously in a separate thread, if imageType() is \l{QDeclarativeImageProvider::ImageType}{ImageType::Image}
+    \endlist
+
+    To specify that an image should be loaded by an image provider, use the
+    \bold {"image:"} scheme for the URL source of the image, followed by the 
+    identifiers of the image provider and the requested image. For example:
+
+    \qml
+    Image { source: "image://myimageprovider/image.png" }
+    \endqml
+
+    This specifies that the image should be loaded by the image provider named 
+    "myimageprovider", and the image to be loaded is named "image.png". The QML engine 
+    invokes the appropriate image provider according to the providers that have
+    been registered through QDeclarativeEngine::addImageProvider().
+
+    Note that the identifiers are case-insensitive, but the rest of the URL will be passed on with
+    preserved case. For example, the below snippet would still specify that the image is loaded by the
+    image provider named "myimageprovider", but it would request a different image than the above snippet
+    ("Image.png" instead of "image.png").
+    \qml
+    Image { source: "image://MyImageProvider/Image.png" }
+    \endqml
+
+    If you want the rest of the URL to be case insensitive, you will have to take care
+    of that yourself inside your image provider.
+
+    \section2 An example
+
+    Here are two images. Their \c source values indicate they should be loaded by
+    an image provider named "colors", and the images to be loaded are "yellow"
+    and "red", respectively:
+
+    \snippet examples/declarative/cppextensions/imageprovider/imageprovider-example.qml 0
+
+    When these images are loaded by QML, it looks for a matching image provider
+    and calls its requestImage() or requestPixmap() method (depending on its
+    imageType()) to load the image. The method is called with the \c id 
+    parameter set to "yellow" for the first image, and "red" for the second.
+
+    Here is an image provider implementation that can load the images 
+    requested by the above QML. This implementation dynamically 
+    generates QPixmap images that are filled with the requested color:
+
+    \snippet examples/declarative/cppextensions/imageprovider/imageprovider.cpp 0
+    \codeline
+    \snippet examples/declarative/cppextensions/imageprovider/imageprovider.cpp 1
+
+    To make this provider accessible to QML, it is registered with the QML engine
+    with a "colors" identifier:
+
+    \code
+    int main(int argc, char *argv[]) 
+    {
+        ...
+
+        QDeclarativeEngine engine;
+        engine->addImageProvider(QLatin1String("colors"), new ColorPixmapProvider);
+
+        ...
+    }
+    \endcode
+
+    Now the images can be successfully loaded in QML:
+
+    \image imageprovider.png
+
+    A complete example is available in Qt's 
+    \l {declarative/cppextensions/imageprovider}{examples/declarative/cppextensions/imageprovider}
+    directory. Note the example registers the provider via a \l{QDeclarativeExtensionPlugin}{plugin}
+    instead of registering it in the application \c main() function as shown above.
+
+
+    \section2 Asynchronous image loading
+
+    Image providers that support QImage loading automatically include support
+    for asychronous loading of images. To enable asynchronous loading for an
+    \l Image source, set \l Image::asynchronous to \c true. When this is enabled, 
+    the image request to the provider is run in a low priority thread,
+    allowing image loading to be executed in the background, and reducing the
+    performance impact on the user interface.
+
+    Asynchronous loading is not supported for image providers that provide
+    QPixmap rather than QImage values, as pixmaps can only be created in the
+    main thread. In this case, if \l {Image::}{asynchronous} is set to 
+    \c true, the value is ignored and the image is loaded
+    synchronously.
+
+    \sa QDeclarativeEngine::addImageProvider()

+    \fn QDeclarativeInfo qmlInfo(const QObject *object)
+    \relates QDeclarativeEngine
+
+    Prints warning messages that include the file and line number for the
+    specified QML \a object.
+
+    When QML types display warning messages, it improves traceability
+    if they include the QML file and line number on which the
+    particular instance was instantiated.
+    
+    To include the file and line number, an object must be passed.  If
+    the file and line number is not available for that instance
+    (either it was not instantiated by the QML engine or location
+    information is disabled), "unknown location" will be used instead.
+
+    For example, 
+
+    \code
+    qmlInfo(object) << tr("component property is a write-once property");
+    \endcode
+
+    prints
+
+    \code
+    QML MyCustomType (unknown location): component property is a write-once property

+\class QDeclarativeListReference
+\since 4.7
+\module QtDeclarative
+\brief The QDeclarativeListReference class allows the manipulation of QDeclarativeListProperty properties.
+
+QDeclarativeListReference allows C++ programs to read from, and assign values to a QML list property in a
+simple and type safe way.  A QDeclarativeListReference can be created by passing an object and property
+name or through a QDeclarativeProperty instance.  These two are equivalant:
+
+\code
+QDeclarativeListReference ref1(object, "children");
+
+QDeclarativeProperty ref2(object, "children");
+QDeclarativeListReference ref2 = qvariant_cast<QDeclarativeListReference>(ref2.read());
+\endcode
+
+Not all QML list properties support all operations.  A set of methods, canAppend(), canAt(), canClear() and
+canCount() allow programs to query whether an operation is supported on a given property.
+
+QML list properties are typesafe.  Only QObject's that derive from the correct base class can be assigned to
+the list.  The listElementType() method can be used to query the QMetaObject of the QObject type supported.
+Attempting to add objects of the incorrect type to a list property will fail.
+
+Like with normal lists, when accessing a list element by index, it is the callers responsibility to ensure 
+that it does not request an out of range element using the count() method before calling at().

+\class QDeclarativeListProperty
+\since 4.7
+\brief The QDeclarativeListProperty class allows applications to expose list-like 
+properties to QML.
+
+QML has many list properties, where more than one object value can be assigned.
+The use of a list property from QML looks like this:
+
+\code
+FruitBasket {
+    fruit: [ 
+        Apple {},
+        Orange{},
+        Banana{}
+    ]
+}
+\endcode
+
+The QDeclarativeListProperty encapsulates a group of function pointers that represet the
+set of actions QML can perform on the list - adding items, retrieving items and
+clearing the list.  In the future, additional operations may be supported.  All 
+list properties must implement the append operation, but the rest are optional.
+
+To provide a list property, a C++ class must implement the operation callbacks, 
+and then return an appropriate QDeclarativeListProperty value from the property getter.
+List properties should have no setter.  In the example above, the Q_PROPERTY()
+declarative will look like this:
+
+\code
+Q_PROPERTY(QDeclarativeListProperty<Fruit> fruit READ fruit);
+\endcode
+
+QML list properties are typesafe - in this case \c {Fruit} is a QObject type that 
+\c {Apple}, \c {Orange} and \c {Banana} all derive from.
+
+\note QDeclarativeListProperty can only be used for lists of QObject-derived object pointers.

+    \class QDeclarativeNetworkAccessManagerFactory
+    \since 4.7
+    \brief The QDeclarativeNetworkAccessManagerFactory class creates QNetworkAccessManager instances for a QML engine.
+
+    A QML engine uses QNetworkAccessManager for all network access.
+    By implementing a factory, it is possible to provide the QML engine
+    with custom QNetworkAccessManager instances with specialized caching,
+    proxy and cookies support.
+
+    To implement a factory, subclass QDeclarativeNetworkAccessManagerFactory and
+    implement the virtual create() method, then assign it to the relevant QML
+    engine using QDeclarativeEngine::setNetworkAccessManagerFactory().
+
+    Note the QML engine may create QNetworkAccessManager instances
+    from multiple threads. Because of this, the implementation of the create()
+    method must be \l{Reentrancy and Thread-Safety}{reentrant}. In addition,
+    the developer should be careful if the signals of the object to be
+    returned from create() are connected to the slots of an object that may
+    be created in a different thread:
+
+    \list
+    \o The QML engine internally handles all requests, and cleans up any
+       QNetworkReply objects it creates. Receiving the
+       QNetworkAccessManager::finished() signal in another thread may not
+       provide the receiver with a valid reply object if it has already
+       been deleted.
+    \o Authentication details provided to QNetworkAccessManager::authenticationRequired()
+       must be provided immediately, so this signal cannot be connected as a
+       Qt::QueuedConnection (or as the default Qt::AutoConnection from another
+       thread).
+    \endlist
+
+    For more information about signals and threads, see
+    \l {Threads and QObjects} and \l {Signals and Slots Across Threads}.
+
+    \sa {declarative/cppextensions/networkaccessmanagerfactory}{NetworkAccessManagerFactory example}
+*/
+
+/*!
+    Destroys the factory. The default implementation does nothing.

+    \fn QNetworkAccessManager *QDeclarativeNetworkAccessManagerFactory::create(QObject *parent)
+
+    Creates and returns a network access manager with the specified \a parent.
+    This method must return a new QNetworkAccessManager instance each time
+    it is called.
+
+    Note: this method may be called by multiple threads, so ensure the
+    implementation of this method is reentrant.

+/*!
+    \class QDeclarativeParserStatus
+    \since 4.7
+    \brief The QDeclarativeParserStatus class provides updates on the QML parser state.
+
+    QDeclarativeParserStatus provides a mechanism for classes instantiated by
+    a QDeclarativeEngine to receive notification at key points in their creation.
+
+    This class is often used for optimization purposes, as it allows you to defer an
+    expensive operation until after all the properties have been set on an
+    object. For example, QML's \l {Text} element uses the parser status
+    to defer text layout until all of its properties have been set (we
+    don't want to layout when the \c text is assigned, and then relayout
+    when the \c font is assigned, and relayout again when the \c width is assigned,
+    and so on).
+
+    To use QDeclarativeParserStatus, you must inherit both a QObject-derived class
+    and QDeclarativeParserStatus, and use the Q_INTERFACES() macro.
+
+    \code
+    class MyObject : public QObject, public QDeclarativeParserStatus
+    {
+        Q_OBJECT
+        Q_INTERFACES(QDeclarativeParserStatus)
+
+    public:
+        MyObject(QObject *parent = 0);
+        ...
+        void classBegin();
+        void componentComplete();
+    }
+    \endcode

+}

+/*! \internal */
+QDeclarativeParserStatus::~QDeclarativeParserStatus()
+{
+    if(d)
+        (*d) = 0;
+}
+
+/*!
+    \fn void QDeclarativeParserStatus::classBegin()
+
+    Invoked after class creation, but before any properties have been set.
+*/
+
+/*!
+    \fn void QDeclarativeParserStatus::componentComplete()
+
+    Invoked after the root component that caused this instantiation has 
+    completed construction.  At this point all static values and binding values
+    have been assigned to the class.

+\class QDeclarativeProperty
+\since 4.7
+\brief The QDeclarativeProperty class abstracts accessing properties on objects created from  QML.
+
+As QML uses Qt's meta-type system all of the existing QMetaObject classes can be used to introspect
+and interact with objects created by QML.  However, some of the new features provided by QML - such 
+as type safety and attached properties - are most easily used through the QDeclarativeProperty class 
+that simplifies some of their natural complexity.
+
+Unlike QMetaProperty which represents a property on a class type, QDeclarativeProperty encapsulates 
+a property on a specific object instance.  To read a property's value, programmers create a 
+QDeclarativeProperty instance and call the read() method.  Likewise to write a property value the
+write() method is used.
+
+For example, for the following QML code:
+
+\qml
+// MyItem.qml
+import QtQuick 1.0
+
+Text { text: "A bit of text" }
+\endqml
+
+The \l Text object's properties could be accessed using QDeclarativeProperty, like this:
+
+\code
+#include <QDeclarativeProperty>
+#include <QGraphicsObject>
+
+...
+
+QDeclarativeView view(QUrl::fromLocalFile("MyItem.qml"));
+QDeclarativeProperty property(view.rootObject(), "font.pixelSize");
+qWarning() << "Current pixel size:" << property.read().toInt();
+property.write(24);
+qWarning() << "Pixel size should now be 24:" << property.read().toInt();
+\endcode

+\class QDeclarativeScriptString
+\since 4.7
+\brief The QDeclarativeScriptString class encapsulates a script and its context.
+
+QDeclarativeScriptString is used to create QObject properties that accept a script "assignment" from QML.
+
+Normally, the following QML would result in a binding being established for the \c script
+property; i.e. \c script would be assigned the value obtained from running \c {myObj.value = Math.max(myValue, 100)}
+
+\qml
+MyType {
+    script: myObj.value = Math.max(myValue, 100)
+}
+\endqml

+\class QDeclarativeDataLoader
+\brief The QDeclarativeDataLoader class abstracts loading files and their dependecies over the network.
+\internal
+
+The QDeclarativeDataLoader class is provided for the exclusive use of the QDeclarativeTypeLoader class.
+
+Clients create QDeclarativeDataBlob instances and submit them to the QDeclarativeDataLoader class
+through the QDeclarativeDataLoader::load() or QDeclarativeDataLoader::loadWithStaticData() methods.
+The loader then fetches the data over the network or from the local file system in an efficient way.
+QDeclarativeDataBlob is an abstract class, so should always be specialized.
+
+Once data is received, the QDeclarativeDataBlob::dataReceived() method is invoked on the blob.  The
+derived class should use this callback to process the received data.  Processing of the data can 
+result in an error being set (QDeclarativeDataBlob::setError()), or one or more dependencies being
+created (QDeclarativeDataBlob::addDependency()).  Dependencies are other QDeclarativeDataBlob's that
+are required before processing can fully complete.
+
+To complete processing, the QDeclarativeDataBlob::done() callback is invoked.  done() is called when
+one of these three preconditions are met.
+
+1.  The QDeclarativeDataBlob has no dependencies.
+2.  The QDeclarativeDataBlob has an error set.
+3.  All the QDeclarativeDataBlob's dependencies are themselves "done()".
+
+Thus QDeclarativeDataBlob::done() will always eventually be called, even if the blob has an error set.

+    \qmlclass WorkerScript QDeclarativeWorkerScript
+    \ingroup qml-utility-elements
+    \brief The WorkerScript element enables the use of threads in QML.
+
+    Use WorkerScript to run operations in a new thread.
+    This is useful for running operations in the background so
+    that the main GUI thread is not blocked.
+
+    Messages can be passed between the new thread and the parent thread
+    using \l sendMessage() and the \l {WorkerScript::onMessage}{onMessage()} handler.
+
+    An example:
+
+    \snippet doc/src/snippets/declarative/workerscript.qml 0
+
+    The above worker script specifies a JavaScript file, "script.js", that handles
+    the operations to be performed in the new thread. Here is \c script.js:
+
+    \quotefile doc/src/snippets/declarative/script.js
+
+    When the user clicks anywhere within the rectangle, \c sendMessage() is
+    called, triggering the \tt WorkerScript.onMessage() handler in
+    \tt script.js. This in turn sends a reply message that is then received
+    by the \tt onMessage() handler of \tt myWorker.
+
+
+    \section3 Restrictions
+
+    Since the \c WorkerScript.onMessage() function is run in a separate thread, the
+    JavaScript file is evaluated in a context separate from the main QML engine. This means
+    that unlike an ordinary JavaScript file that is imported into QML, the \c script.js
+    in the above example cannot access the properties, methods or other attributes
+    of the QML item, nor can it access any context properties set on the QML object
+    through QDeclarativeContext.
+
+    Additionally, there are restrictions on the types of values that can be passed to and
+    from the worker script. See the sendMessage() documentation for details.

+
+    The Animation element cannot be used directly in a QML file.  It exists
+    to provide a set of common properties and methods, available across all the
+    other animation types that inherit from it.  Attempting to use the Animation
+    element directly will result in an error.

+    \qmlproperty bool Animation::running
+    This property holds whether the animation is currently running.
+
+    The \c running property can be set to declaratively control whether or not
+    an animation is running.  The following example will animate a rectangle
+    whenever the \l MouseArea is pressed.
+
+    \code
+    Rectangle {
+        width: 100; height: 100

+        }
+        MouseArea { id: myMouse }
+    }
+    \endcode
+
+    Likewise, the \c running property can be read to determine if the animation
+    is running.  In the following example the text element will indicate whether
+    or not the animation is running.
+
+    \code
+    NumberAnimation { id: myAnimation }
+    Text { text: myAnimation.running ? "Animation is running" : "Animation is not running" }
+    \endcode
+
+    Animations can also be started and stopped imperatively from JavaScript
+    using the \c start() and \c stop() methods.
+
+    By default, animations are not running. Though, when the animations are assigned to properties,
+    as property value sources using the \e on syntax, they are set to running by default.

+    \ingroup qml-animation-transition
+    \since 4.7
+    \inherits Animation
+    \brief The PropertyAction element allows immediate property changes during animation.
+
+    PropertyAction is used to specify an immediate property change during an
+    animation. The property change is not animated.
+
+    It is useful for setting non-animated property values during an animation.
+
+    For example, here is a SequentialAnimation that sets the image's
+    \l {Image::}{smooth} property to \c true, animates the width of the image,
+    then sets \l {Image::}{smooth} back to \c false:
+
+    \snippet doc/src/snippets/declarative/propertyaction.qml standalone
+
+    PropertyAction is also useful for setting the exact point at which a property
+    change should occur during a \l Transition. For example, if PropertyChanges
+    was used in a \l State to rotate an item around a particular
+    \l {Item::}{transformOrigin}, it might be implemented like this:
+
+    \snippet doc/src/snippets/declarative/propertyaction.qml transition
+
+    However, with this code, the \c transformOrigin is not set until \e after
+    the animation, as a \l State is taken to define the values at the \e end of
+    a transition. The animation would rotate at the default \c transformOrigin,
+    then jump to \c Item.BottomRight. To fix this, insert a PropertyAction
+    before the RotationAnimation begins:
+
+    \snippet doc/src/snippets/declarative/propertyaction-sequential.qml sequential
+
+    This immediately sets the \c transformOrigin property to the value defined
+    in the end state of the \l Transition (i.e. the value defined in the
+    PropertyAction object) so that the rotation animation begins with the
+    correct transform origin.

+    \brief The RotationAnimation element animates changes in rotation values.
+
+    RotationAnimation is a specialized PropertyAnimation that gives control
+    over the direction of rotation during an animation.
+
+    By default, it rotates in the direction
+    of the numerical change; a rotation from 0 to 240 will rotate 240 degrees
+    clockwise, while a rotation from 240 to 0 will rotate 240 degrees
+    counterclockwise. The \l direction property can be set to specify the
+    direction in which the rotation should occur.
+
+    In the following example we use RotationAnimation to animate the rotation
+    between states via the shortest path:
+
+    \snippet doc/src/snippets/declarative/rotationanimation.qml 0
+
+    Notice the RotationAnimation did not need to set a \l target
+    value. As a convenience, when used in a transition, RotationAnimation will rotate all
+    properties named "rotation" or "angle". You can override this by providing
+    your own properties via \l {PropertyAnimation::properties}{properties} or
+    \l {PropertyAnimation::property}{property}.
+
+    Also, note the \l Rectangle will be rotated around its default
+    \l {Item::}{transformOrigin} (which is \c Item.Center). To use a different
+    transform origin, set the origin in the PropertyChanges object and apply
+    the change at the start of the animation using PropertyAction. See the
+    PropertyAction documentation for more details.
+
+    Like any other animation element, a RotationAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.

+    \brief The PropertyAnimation element animates changes in property values.
+
+    PropertyAnimation provides a way to animate changes to a property's value.
+
+    It can be used to define animations in a number of ways:
+
+    \list
+    \o In a \l Transition
+
+    For example, to animate any objects that have changed their \c x or \c y properties
+    as a result of a state change, using an \c InOutQuad easing curve:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml transition
+
+
+    \o In a \l Behavior
+
+    For example, to animate all changes to a rectangle's \c x property:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml behavior
+
+
+    \o As a property value source
+
+    For example, to repeatedly animate the rectangle's \c x property:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml propertyvaluesource
+
+
+    \o In a signal handler
+
+    For example, to fade out \c theObject when clicked:
+    \qml
+    MouseArea {
+        anchors.fill: theObject
+        onClicked: PropertyAnimation { target: theObject; property: "opacity"; to: 0 }
+    }
+    \endqml
+
+    \o Standalone
+
+    For example, to animate \c rect's \c width property over 500ms, from its current width to 30:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml standalone
+
+    \endlist
+
+    Depending on how the animation is used, the set of properties normally used will be
+    different. For more information see the individual property documentation, as well
+    as the \l{QML Animation and Transitions} introduction.
+
+    Note that PropertyAnimation inherits the abstract \l Animation element.

+
+    These properties are used as a set to determine which properties should be animated.
+    The singular and plural forms are functionally identical, e.g.
+    \qml
+    NumberAnimation { target: theItem; property: "x"; to: 500 }

+    has the same meaning as
+    \qml
+    NumberAnimation { targets: theItem; properties: "x"; to: 500 }
+    \endqml
+    The singular forms are slightly optimized, so if you do have only a single target/property
+    to animate you should try to use them.
+
+    The \c targets property allows multiple targets to be set. For example, this animates the

+  \ingroup qml-animation-transition
+    \since 4.7
+    \inherits Animation
+    \brief The ParentAnimation element animates changes in parent values.
+
+    ParentAnimation is used to animate a parent change for an \l Item.
+
+    For example, the following ParentChange changes \c blueRect to become
+    a child of \c redRect when it is clicked. The inclusion of the
+    ParentAnimation, which defines a NumberAnimation to be applied during
+    the transition, ensures the item animates smoothly as it moves to
+    its new parent:
+
+    \snippet doc/src/snippets/declarative/parentanimation.qml 0
+
+    A ParentAnimation can contain any number of animations. These animations will
+    be run in parallel; to run them sequentially, define them within a
+    SequentialAnimation.
+
+    In some cases, such as when reparenting between items with clipping enabled, it is useful
+    to animate the parent change via another item that does not have clipping
+    enabled. Such an item can be set using the \l via property.
+
+    For convenience, when a ParentAnimation is used in a \l Transition, it will
+    animate any ParentChange that has occurred during the state change.
+    This can be overridden by setting a specific target item using the
+    \l target property.
+
+    Like any other animation element, a ParentAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.

+    For convenience, when an AnchorAnimation is used in a \l Transition, it will
+    animate any AnchorChanges that have occurred during the state change.
+    This can be overridden by setting a specific target item using the
+    \l target property.
+
+    Like any other animation element, an AnchorAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.

+
+    A Behavior defines the default animation to be applied whenever a
+    particular property value changes.
+
+    For example, the following Behavior defines a NumberAnimation to be run
+    whenever the \l Rectangle's \c width value changes. When the MouseArea
+    is clicked, the \c width is changed, triggering the behavior's animation:
+
+    \snippet doc/src/snippets/declarative/behavior.qml 0
+
+    Note that a property cannot have more than one assigned Behavior. To provide
+    multiple animations within a Behavior, use ParallelAnimation or
+    SequentialAnimation.
+
+    If a \l{QML States}{state change} has a \l Transition that matches the same property as a
+    Behavior, the \l Transition animation overrides the Behavior for that
+    state change. For general advice on using Behaviors to animate state changes, see
+    \l{Using QML Behaviors with States}.

+    \brief The Binding element allows arbitrary property bindings to be created.
+
+    Sometimes it is necessary to bind to a property of an object that wasn't
+    directly instantiated by QML - generally a property of a class exported
+    to QML by C++. In these cases, regular property binding doesn't work. Binding
+    allows you to bind any value to any property.
+
+    For example, imagine a C++ application that maps an "app.enteredText"
+    property into QML. You could use Binding to update the enteredText property
+    like this.
+    \code
+    TextEdit { id: myTextField; text: "Please type here..." }
+    Binding { target: app; property: "enteredText"; value: myTextField.text }
+    \endcode
+    Whenever the text in the TextEdit is updated, the C++ property will be
+    updated also.
+
+    If the binding target or binding property is changed, the bound value is
+    immediately pushed onto the new target.

+    \ingroup qml-utility-elements
+    \since 4.7
+    \brief A Connections element describes generalized connections to signals.
+
+    A Connections object creates a connection to a QML signal.
+
+    When connecting to signals in QML, the usual way is to create an
+    "on<Signal>" handler that reacts when a signal is received, like this:
+
+    \qml
+    MouseArea {
+        onClicked: { foo(parameters) }
+    }
+    \endqml
+
+    However, it is not possible to connect to a signal in this way in some 
+    cases, such as when:
+
+    \list
+        \i Multiple connections to the same signal are required
+        \i Creating connections outside the scope of the signal sender
+        \i Connecting to targets not defined in QML
+    \endlist
+
+    When any of these are needed, the Connections element can be used instead.
+
+    For example, the above code can be changed to use a Connections object,
+    like this:
+
+    \qml
+    MouseArea {
+        Connections {
+            onClicked: foo(parameters)
+        }
+    }
+    \endqml
+
+    More generally, the Connections object can be a child of some object other than
+    the sender of the signal:
+
+    \qml
+    MouseArea {
+        id: area
+    }
+    // ...
+    \endqml
+    \qml
+    Connections {
+        target: area
+        onClicked: foo(parameters)

+/*!
+    \qmlclass ListModel QDeclarativeListModel
+    \ingroup qml-working-with-data
+    \since 4.7
+    \brief The ListModel element defines a free-form list data source.
+
+    The ListModel is a simple container of ListElement definitions, each containing data roles.
+    The contents can be defined dynamically, or explicitly in QML.
+
+    The number of elements in the model can be obtained from its \l count property.
+    A number of familiar methods are also provided to manipulate the contents of the
+    model, including append(), insert(), move(), remove() and set(). These methods
+    accept dictionaries as their arguments; these are translated to ListElement objects
+    by the model.
+
+    Elements can be manipulated via the model using the setProperty() method, which
+    allows the roles of the specified element to be set and changed.
+
+    \section1 Example Usage
+
+    The following example shows a ListModel containing three elements, with the roles
+    "name" and "cost".
+
+    \div {class="float-right"}
+    \inlineimage listmodel.png
+    \enddiv
+
+    \snippet doc/src/snippets/declarative/listmodel.qml 0
+
+    \clearfloat
+    Roles (properties) in each element must begin with a lower-case letter and
+    should be common to all elements in a model. The ListElement documentation
+    provides more guidelines for how elements should be defined.
+
+    Since the example model contains an \c id property, it can be referenced
+    by views, such as the ListView in this example:
+
+    \snippet doc/src/snippets/declarative/listmodel-simple.qml 0
+    \dots 8
+    \snippet doc/src/snippets/declarative/listmodel-simple.qml 1
+
+    It is possible for roles to contain list data.  In the following example we
+    create a list of fruit attributes:
+
+    \snippet doc/src/snippets/declarative/listmodel-nested.qml model
+
+    The delegate displays all the fruit attributes:
+
+    \div {class="float-right"}
+    \inlineimage listmodel-nested.png
+    \enddiv
+
+    \snippet doc/src/snippets/declarative/listmodel-nested.qml delegate
+
+    \clearfloat
+    \section1 Modifying List Models
+
+    The content of a ListModel may be created and modified using the clear(),
+    append(), set(), insert() and setProperty() methods.  For example:
+
+    \snippet doc/src/snippets/declarative/listmodel-modify.qml delegate
+
+    Note that when creating content dynamically the set of available properties
+    cannot be changed once set. Whatever properties are first added to the model
+    are the only permitted properties in the model.
+
+    \section1 Using Threaded List Models with WorkerScript
+
+    ListModel can be used together with WorkerScript access a list model
+    from multiple threads. This is useful if list modifications are
+    synchronous and take some time: the list operations can be moved to a
+    different thread to avoid blocking of the main GUI thread.
+
+    Here is an example that uses WorkerScript to periodically append the
+    current time to a list model:
+
+    \snippet examples/declarative/threading/threadedlistmodel/timedisplay.qml 0
+
+    The included file, \tt dataloader.js, looks like this:
+
+    \snippet examples/declarative/threading/threadedlistmodel/dataloader.js 0
+
+    The timer in the main example sends messages to the worker script by calling
+    \l WorkerScript::sendMessage(). When this message is received,
+    \l{WorkerScript::onMessage}{WorkerScript.onMessage()} is invoked in \c dataloader.js,
+    which appends the current time to the list model.
+
+    Note the call to sync() from the \l{WorkerScript::onMessage}{WorkerScript.onMessage()}
+    handler. You must call sync() or else the changes made to the list from the external
+    thread will not be reflected in the list model in the main thread.
+
+    \section1 Restrictions
+
+    If a list model is to be accessed from a WorkerScript, it cannot
+    contain list-type data. So, the following model cannot be used from a WorkerScript
+    because of the list contained in the "attributes" property:
+
+    \code
+    ListModel {
+        id: fruitModel
+        ListElement {
+            name: "Apple"
+            cost: 2.45
+            attributes: [
+                ListElement { description: "Core" },
+                ListElement { description: "Deciduous" }
+            ]
+        }
+    }
+    \endcode
+
+    In addition, the WorkerScript cannot add list-type data to the model.
+
+    \sa {qmlmodels}{Data Models}, {declarative/threading/threadedlistmodel}{Threaded ListModel example}, QtDeclarative
+*/
+
+
+/*
+    A ListModel internally uses either a NestedListModel or FlatListModel.
+
+    A NestedListModel can contain lists of ListElements (which
+    when retrieved from get() is accessible as a list model within the list
+    model) whereas a FlatListModel cannot.
+
+    ListModel uses a NestedListModel to begin with, and if the model is later 
+    used from a WorkerScript, it changes to use a FlatListModel instead. This
+    is because ModelNode (which abstracts the nested list model data) needs
+    access to the declarative engine and script engine, which cannot be
+    safely used from outside of the main thread.

+    List elements are defined like other QML elements except that they contain
+    a collection of \e role definitions instead of properties. Using the same
+    syntax as property definitions, roles both define how the data is accessed
+    and include the data itself.
+
+    The names used for roles must begin with a lower-case letter and should be
+    common to all elements in a given model. Values must be simple constants; either
+    strings (quoted and optionally within a call to QT_TR_NOOP), boolean values
+    (true, false), numbers, or enumeration values (such as AlignText.AlignHCenter).
+
+    \section1 Referencing Roles
+
+    The role names are used by delegates to obtain data from list elements.
+    Each role name is accessible in the delegate's scope, and refers to the
+    corresponding role in the current element. Where a role name would be
+    ambiguous to use, it can be accessed via the \l{ListView::}{model}
+    property (e.g., \c{model.cost} instead of \c{cost}).
+
+    \section1 Example Usage
+
+    The following model defines a series of list elements, each of which
+    contain "name" and "cost" roles and their associated values.
+
+    \snippet doc/src/snippets/declarative/qml-data-models/listelements.qml model
+
+    The delegate obtains the name and cost for each element by simply referring
+    to \c name and \c cost:

+    \brief Package provides a collection of named items.
+
+    The Package class is used in conjunction with
+    VisualDataModel to enable delegates with a shared context
+    to be provided to multiple views.
+
+    Any item within a Package may be assigned a name via the
+    \l{Package::name}{Package.name} attached property.
+
+    The example below creates a Package containing two named items;
+    \e list and \e grid.  The third element in the package (the \l Rectangle) is parented to whichever
+    delegate it should appear in.  This allows an item to move
+    between views.
+
+    \snippet examples/declarative/modelviews/package/Delegate.qml 0
+
+    These named items are used as the delegates by the two views who
+    reference the special \l{VisualDataModel::parts} property to select
+    a model which provides the chosen delegate.
+
+    \snippet examples/declarative/modelviews/package/view.qml 0

+    \qmlclass PropertyChanges QDeclarativePropertyChanges
+    \ingroup qml-state-elements
+    \since 4.7
+    \brief The PropertyChanges element describes new property bindings or values for a state.
+
+    PropertyChanges is used to define the property values or bindings in a 
+    \l State. This enables an item's property values to be changed when it
+    \l {QML States}{changes between states}.
+
+    To create a PropertyChanges object, specify the \l target item whose 
+    properties are to be modified, and define the new property values or
+    bindings. For example:
+    
+    \snippet doc/src/snippets/declarative/propertychanges.qml import 
+    \codeline
+    \snippet doc/src/snippets/declarative/propertychanges.qml 0
+
+    When the mouse is pressed, the \l Rectangle changes to the \e resized
+    state. In this state, the PropertyChanges object sets the rectangle's 
+    color to blue and the \c height value to that of \c container.height.
+
+    Note this automatically binds \c rect.height to \c container.height 
+    in the \e resized state. If a property binding should not be
+    established, and the height should just be set to the value of
+    \c container.height at the time of the state change, set the \l explicit
+    property to \c true.
+   
+    A PropertyChanges object can also override the default signal handler
+    for an object to implement a signal handler specific to the new state:
+
+    \qml
+    PropertyChanges {
+        target: myMouseArea
+        onClicked: doSomethingDifferent()
+    }
+    \endqml
+
+    \note PropertyChanges can be used to change anchor margins, but not other anchor
+    values; use AnchorChanges for this instead. Similarly, to change an \l Item's
+    \l {Item::}{parent} value, use ParentChanges instead.
+
+
+    \section2 Resetting property values
+
+    The \c undefined value can be used to reset the property value for a state.
+    In the following example, when \c theText changes to the \e widerText
+    state, its \c width property is reset, giving the text its natural width
+    and displaying the whole string on a single line.
+
+    \snippet doc/src/snippets/declarative/propertychanges.qml reset
+
+
+    \section2 Immediate property changes in transitions
+
+    When \l{QML Animation and Transitions}{Transitions} are used to animate
+    state changes, they animate properties from their values in the current
+    state to those defined in the new state (as defined by PropertyChanges
+    objects). However, it is sometimes desirable to set a property value
+    \e immediately during a \l Transition, without animation; in these cases,
+    the PropertyAction element can be used to force an immediate property
+    change.
+
+    See the PropertyAction documentation for more details.

+    \class QDeclarativePropertyMap
+    \since 4.7
+    \brief The QDeclarativePropertyMap class allows you to set key-value pairs that can be used in QML bindings.
+
+    QDeclarativePropertyMap provides a convenient way to expose domain data to the UI layer.
+    The following example shows how you might declare data in C++ and then
+    access it in QML.
+
+    In the C++ file:
+    \code
+    // create our data
+    QDeclarativePropertyMap ownerData;
+    ownerData.insert("name", QVariant(QString("John Smith")));
+    ownerData.insert("phone", QVariant(QString("555-5555")));
+
+    // expose it to the UI layer
+    QDeclarativeView view;
+    QDeclarativeContext *ctxt = view.rootContext();
+    ctxt->setContextProperty("owner", &ownerData);
+
+    view.setSource(QUrl::fromLocalFile("main.qml"));
+    view.show();
+    \endcode
+
+    Then, in \c main.qml:
+    \code
+    Text { text: owner.name + " " + owner.phone }
+    \endcode
+
+    The binding is dynamic - whenever a key's value is updated, anything bound to that
+    key will be updated as well.
+
+    To detect value changes made in the UI layer you can connect to the valueChanged() signal.
+    However, note that valueChanged() is \bold NOT emitted when changes are made by calling insert()
+    or clear() - it is only emitted when a value is updated from QML.
+
+    \note It is not possible to remove keys from the map; once a key has been added, you can only
+    modify or clear its associated value.

+    \qmlclass SmoothedAnimation QDeclarativeSmoothedAnimation
+    \ingroup qml-animation-transition
+    \since 4.7
+    \inherits NumberAnimation
+    \brief The SmoothedAnimation element allows a property to smoothly track a value.
+
+    A SmoothedAnimation animates a property's value to a set target value
+    using an ease in/out quad easing curve.  When the target value changes,
+    the easing curves used to animate between the old and new target values
+    are smoothly spliced together to create a smooth movement to the new
+    target value that maintains the current velocity.
+
+    The follow example shows one \l Rectangle tracking the position of another
+    using SmoothedAnimation. The green rectangle's \c x and \c y values are
+    bound to those of the red rectangle. Whenever these values change, the
+    green rectangle smoothly animates to its new position:
+
+    \snippet doc/src/snippets/declarative/smoothedanimation.qml 0
+
+    A SmoothedAnimation can be configured by setting the \l velocity at which the
+    animation should occur, or the \l duration that the animation should take.
+    If both the \l velocity and \l duration are specified, the one that results in
+    the quickest animation is chosen for each change in the target value.
+
+    For example, animating from 0 to 800 will take 4 seconds if a velocity
+    of 200 is set, will take 8 seconds with a duration of 8000 set, and will
+    take 4 seconds with both a velocity of 200 and a duration of 8000 set.
+    Animating from 0 to 20000 will take 10 seconds if a velocity of 200 is set,
+    will take 8 seconds with a duration of 8000 set, and will take 8 seconds
+    with both a velocity of 200 and a duration of 8000 set.
+
+    The default velocity of SmoothedAnimation is 200 units/second.  Note that if the range of the
+    value being animated is small, then the velocity will need to be adjusted
+    appropriately.  For example, the opacity of an item ranges from 0 - 1.0.
+    To enable a smooth animation in this range the velocity will need to be
+    set to a value such as 0.5 units/second.  Animating from 0 to 1.0 with a velocity
+    of 0.5 will take 2000 ms to complete.
+
+    Like any other animation element, a SmoothedAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.

+    \since 4.7
+
+    \brief The SpringAnimation element allows a property to track a value in a spring-like motion.
+
+    SpringAnimation mimics the oscillatory behavior of a spring, with the appropriate \l spring constant to
+    control the acceleration and the \l damping to control how quickly the effect dies away.
+
+    You can also limit the maximum \l velocity of the animation.
+
+    The following \l Rectangle moves to the position of the mouse using a
+    SpringAnimation when the mouse is clicked. The use of the \l Behavior
+    on the \c x and \c y values indicates that whenever these values are
+    changed, a SpringAnimation should be applied.
+
+    \snippet doc/src/snippets/declarative/springanimation.qml 0
+
+    Like any other animation element, a SpringAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.

+    \ingroup qml-state-elements
+    \since 4.7
+    \brief The State element defines configurations of objects and properties.
+
+    A \e state is a set of batched changes from the default configuration.
+
+    All items have a default state that defines the default configuration of objects
+    and property values. New states can be defined by adding State items to the \l {Item::states}{states} property to
+    allow items to switch between different configurations. These configurations
+    can, for example, be used to apply different sets of property values or execute
+    different scripts.
+
+    The following example displays a single \l Rectangle. In the default state, the rectangle
+    is colored black. In the "clicked" state, a PropertyChanges element changes the
+    rectangle's color to red. Clicking within the MouseArea toggles the rectangle's state
+    between the default state and the "clicked" state, thus toggling the color of the
+    rectangle between black and red.
+
+    \snippet doc/src/snippets/declarative/state.qml 0
+
+    Notice the default state is referred to using an empty string ("").
+
+    States are commonly used together with \l{QML Animation and Transitions}{Transitions} to provide
+    animations when state changes occur.
+
+    \note Setting the state of an object from within another state of the same object is
+    not allowed.

+    \preliminary
+    \qmlclass ParentChange QDeclarativeParentChange
+    \ingroup qml-state-elements
+    \brief The ParentChange element allows you to reparent an Item in a state change.
+
+    ParentChange reparents an item while preserving its visual appearance (position, size,
+    rotation, and scale) on screen. You can then specify a transition to move/resize/rotate/scale
+    the item to its final intended appearance.
+
+    ParentChange can only preserve visual appearance if no complex transforms are involved.
+    More specifically, it will not work if the transform property has been set for any
+    items involved in the reparenting (i.e. items in the common ancestor tree
+    for the original and new parent).
+
+    The example below displays a large red rectangle and a small blue rectangle, side by side. 
+    When the \c blueRect is clicked, it changes to the "reparented" state: its parent is changed to \c redRect and it is 
+    positioned at (10, 10) within the red rectangle, as specified in the ParentChange.
+
+    \snippet doc/src/snippets/declarative/parentchange.qml 0
+
+    \image parentchange.png
+
+    You can specify at which point in a transition you want a ParentChange to occur by
+    using a ParentAnimation.

+
+    The SystemPalette element provides access to the Qt application
+    palettes. This provides information about the standard colors used 
+    for application windows, buttons and other features. These colors
+    are grouped into three \e {color groups}: \c Active, \c Inactive,
+    and \c Disabled.  See the QPalette documentation for details about
+    color groups and the properties provided by SystemPalette.
+
+    This can be used to color items in a way that provides a more
+    native look and feel.
+
+    The following example creates a palette from the \c Active color
+    group and uses this to color the window and text items
+    appropriately:

+/*!
+    \internal
+    \class QDeclarativeTimeLine
+    \brief The QDeclarativeTimeLine class provides a timeline for controlling animations.
+
+    QDeclarativeTimeLine is similar to QTimeLine except:
+    \list
+    \i It updates QDeclarativeTimeLineValue instances directly, rather than maintaining a single
+    current value.
+
+    For example, the following animates a simple value over 200 milliseconds:
+    \code
+    QDeclarativeTimeLineValue v(<starting value>);
+    QDeclarativeTimeLine tl;
+    tl.move(v, 100., 200);
+    tl.start()
+    \endcode
+
+    If your program needs to know when values are changed, it can either
+    connect to the QDeclarativeTimeLine's updated() signal, or inherit from QDeclarativeTimeLineValue
+    and reimplement the QDeclarativeTimeLineValue::setValue() method.
+
+    \i Supports multiple QDeclarativeTimeLineValue, arbitrary start and end values and allows
+    animations to be strung together for more complex effects.
+
+    For example, the following animation moves the x and y coordinates of
+    an object from wherever they are to the position (100, 100) in 50
+    milliseconds and then further animates them to (100, 200) in 50
+    milliseconds:
+
+    \code
+    QDeclarativeTimeLineValue x(<starting value>);
+    QDeclarativeTimeLineValue y(<starting value>);
+
+    QDeclarativeTimeLine tl;
+    tl.start();
+
+    tl.move(x, 100., 50);
+    tl.move(y, 100., 50);
+    tl.move(y, 200., 50);
+    \endcode
+
+    \i All QDeclarativeTimeLine instances share a single, synchronized clock.
+
+    Actions scheduled within the same event loop tick are scheduled
+    synchronously against each other, regardless of the wall time between the
+    scheduling.  Synchronized scheduling applies both to within the same
+    QDeclarativeTimeLine and across separate QDeclarativeTimeLine's within the same process.
+
+    \endlist
+
+    Currently easing functions are not supported.

+    \brief The Timer item triggers a handler at a specified interval.
+
+    A Timer can be used to trigger an action either once, or repeatedly
+    at a given interval.
+
+    Here is a Timer that shows the current date and time, and updates
+    the text every 500 milliseconds. It uses the JavaScript \c Date
+    object to access the current time.
+
+    \qml
+    import QtQuick 1.0
+
+    Item {
+        Timer {
+            interval: 500; running: true; repeat: true
+            onTriggered: time.text = Date().toString()
+        }
+
+        Text { id: time }
+    }
+    \endqml
+
+    The Timer element is synchronized with the animation timer.  Since the animation
+    timer is usually set to 60fps, the resolution of Timer will be
+    at best 16ms.
+
+    If the Timer is running and one of its properties is changed, the
+    elapsed time will be reset.  For example, if a Timer with interval of
+    1000ms has its \e repeat property changed 500ms after starting, the
+    elapsed time will be reset to 0, and the Timer will be triggered
+    1000ms later.

+    \qmlclass Transition QDeclarativeTransition
+    \ingroup qml-animation-transition
+    \since 4.7
+    \brief The Transition element defines animated transitions that occur on state changes.
+
+    A Transition defines the animations to be applied when a \l State change occurs.
+
+    For example, the following \l Rectangle has two states: the default state, and
+    an added "moved" state. In the "moved state, the rectangle's position changes
+    to (50, 50).  The added Transition specifies that when the rectangle
+    changes between the default and the "moved" state, any changes
+    to the \c x and \c y properties should be animated, using an \c Easing.InOutQuad.
+
+    \snippet doc/src/snippets/declarative/transition.qml 0
+
+    Notice the example does not require \l{PropertyAnimation::}{to} and
+    \l{PropertyAnimation::}{from} values for the NumberAnimation. As a convenience,
+    these properties are automatically set to the values of \c x and \c y before
+    and after the state change; the \c from values are provided by
+    the current values of \c x and \c y, and the \c to values are provided by
+    the PropertyChanges object. If you wish, you can provide \l{PropertyAnimation::}{to} and
+    \l{PropertyAnimation::}{from} values anyway to override the default values.
+
+    By default, a Transition's animations are applied for any state change in the
+    parent item. The  Transition \l {Transition::}{from} and \l {Transition::}{to}
+    values can be set to restrict the animations to only be applied when changing
+    from one particular state to another.
+
+    To define multiple transitions, specify \l Item::transitions as a list:
+
+    \snippet doc/src/snippets/declarative/transitions-list.qml list of transitions
+
+    If multiple Transitions are specified, only a single (best-matching) Transition will be applied for any particular
+    state change. In the example above, when changing to \c state1, the first transition will be used, rather
+    than the more generic second transition.
+
+    If a state change has a Transition that matches the same property as a
+    \l Behavior, the Transition animation overrides the \l Behavior for that
+    state change.

+    \class QDeclarativeView
+    \since 4.7
+    \brief The QDeclarativeView class provides a widget for displaying a Qt Declarative user interface.
+
+    QDeclarativeItem objects can be placed on a standard QGraphicsScene and
+    displayed with QGraphicsView. QDeclarativeView is a QGraphicsView subclass
+    provided as a convenience for displaying QML files, and connecting between
+    QML and C++ Qt objects.
+
+    QDeclarativeView provides:
+
+    \list
+    \o Management of QDeclarativeComponent loading and object creation
+    \o Initialization of QGraphicsView for optimal performance with QML using these settings:
+        \list
+        \o QGraphicsView::setOptimizationFlags(QGraphicsView::DontSavePainterState)
+        \o QGraphicsView::setViewportUpdateMode(QGraphicsView::BoundingRectViewportUpdate)
+        \o QGraphicsScene::setItemIndexMethod(QGraphicsScene::NoIndex)
+        \endlist
+    \o Initialization of QGraphicsView for QML key handling using these settings:
+        \list
+        \o QGraphicsView::viewport()->setFocusPolicy(Qt::NoFocus)
+        \o QGraphicsView::setFocusPolicy(Qt::StrongFocus)
+        \o QGraphicsScene::setStickyFocus(true)
+        \endlist
+    \endlist
+
+    Typical usage:
+
+    \code
+    QDeclarativeView *view = new QDeclarativeView;
+    view->setSource(QUrl::fromLocalFile("myqmlfile.qml"));
+    view->show();
+    \endcode
+
+    Since QDeclarativeView is a QWidget-based class, it can be used to
+    display QML interfaces within QWidget-based GUI applications that do not
+    use the Graphics View framework.
+
+    To receive errors related to loading and executing QML with QDeclarativeView,
+    you can connect to the statusChanged() signal and monitor for QDeclarativeView::Error.
+    The errors are available via QDeclarativeView::errors().
+
+    If you're using your own QGraphicsScene-based scene with QDeclarativeView, remember to
+    enable scene's sticky focus mode and to set itemIndexMethod to QGraphicsScene::NoIndex.

+    \ingroup qml-working-with-data
+  \since 4.7
+    \brief The XmlListModel element is used to specify a read-only model using XPath expressions.
+
+    XmlListModel is used to create a read-only model from XML data. It can be used as a data source
+    for view elements (such as ListView, PathView, GridView) and other elements that interact with model
+    data (such as \l Repeater).
+
+    For example, if there is a XML document at http://www.mysite.com/feed.xml like this:
+
+    \code
+    <?xml version="1.0" encoding="utf-8"?>
+    <rss version="2.0">
+        ...
+        <channel>
+            <item>
+                <title>A blog post</title>
+                <pubDate>Sat, 07 Sep 2010 10:00:01 GMT</pubDate>
+            </item>
+            <item>
+                <title>Another blog post</title>
+                <pubDate>Sat, 07 Sep 2010 15:35:01 GMT</pubDate>
+            </item>
+        </channel>
+    </rss>
+    \endcode
+
+    A XmlListModel could create a model from this data, like this:
+
+    \qml
+    import QtQuick 1.0
+
+    XmlListModel {
+        id: xmlModel
+        source: "http://www.mysite.com/feed.xml"
+        query: "/rss/channel/item"
+
+        XmlRole { name: "title"; query: "title/string()" }
+        XmlRole { name: "pubDate"; query: "pubDate/string()" }
+    }
+    \endqml
+
+    The \l {XmlListModel::query}{query} value of "/rss/channel/item" specifies that the XmlListModel should generate
+    a model item for each \c <item> in the XML document. 
+    
+    The XmlRole objects define the
+    model item attributes. Here, each model item will have \c title and \c pubDate 
+    attributes that match the \c title and \c pubDate values of its corresponding \c <item>.
+    (See \l XmlRole::query for more examples of valid XPath expressions for XmlRole.)
+
+    The model could be used in a ListView, like this:
+
+    \qml
+    ListView {
+        width: 180; height: 300
+        model: xmlModel
+        delegate: Text { text: title + ": " + pubDate }
+    }
+    \endqml
+
+    \image qml-xmllistmodel-example.png
+
+    The XmlListModel data is loaded asynchronously, and \l status
+    is set to \c XmlListModel.Ready when loading is complete.
+    Note this means when XmlListModel is used for a view, the view is not
+    populated until the model is loaded.
+
+
+    \section2 Using key XML roles
+
+    You can define certain roles as "keys" so that when reload() is called,
+    the model will only add and refresh data that contains new values for
+    these keys.
+
+    For example, if above role for "pubDate" was defined like this instead:
+
+    \qml
+        XmlRole { name: "pubDate"; query: "pubDate/string()"; isKey: true }
+    \endqml
+
+    Then when reload() is called, the model will only add and reload
+    items with a "pubDate" value that is not already 
+    present in the model. 
+
+    This is useful when displaying the contents of XML documents that
+    are incrementally updated (such as RSS feeds) to avoid repainting the
+    entire contents of a model in a view.
+
+    If multiple key roles are specified, the model only adds and reload items
+    with a combined value of all key roles that is not already present in
+    the model.
