Initial import from the monolithic Qt.

This is the beginning of revision history for this module. If you
want to look at revision history older than this, please refer to the
Qt Git wiki for how to use Git history grafting. At the time of
writing, this wiki is located here:

http://qt.gitorious.org/qt/pages/GitIntroductionWithQt

If you have already performed the grafting and you don't see any
history beyond this commit, try running "git log" with the "--follow"
argument.

+/*!
+    \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"));

+    \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();

+    \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()}.

+
+    Creates and returns an object instance of this component that will have

+    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");

+/*!
+    \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.

+
+    QDeclarativeDomValue's can be assigned to QML \l {QDeclarativeDomProperty}{properties}.  In
+    QML, properties can be assigned various different values, including basic
+    literals, property bindings, property value sources, objects and lists of
+    values.  The QDeclarativeDomValue class allows a programmer to determine the specific
+    value type being assigned and access more detailed information through a
+    corresponding value type class.
+
+    For example, in the following example,
+
+    \qml
+Text {
+    text: "Hello World!"
+    y: Other.y
+}
+    \endqml
+
+    The text property is being assigned a literal, and the y property a property
+    binding.  To output the values assigned to the text and y properties in the
+    above example from C++,
+
+    \code
+    QDeclarativeDomDocument document;
+    QDeclarativeDomObject root = document.rootObject();
+
+    QDeclarativeDomProperty text = root.property("text");

+  \brief The QtObject element is the most basic element in QML.
+
+  The QtObject element is a non-visual element which contains only the
+  objectName property. 
+
+  It can be useful to create a QtObject if you need an extremely
+  lightweight element to enclose a set of custom properties:
+
+  \snippet doc/src/snippets/declarative/qtobject.qml 0
+
+  It can also be useful for C++ integration, as it is just a plain

+/*!
+  \qmlproperty string QML:QtObject::objectName
+  This property holds the QObject::objectName for this specific object instance.
+
+  This allows a C++ application to locate an item within a QML component
+  using the QObject::findChild() method. For example, the following C++ 
+  application locates the child \l Rectangle item and dynamically changes its
+  \c color value:
+
+    \qml
+    // MyRect.qml
+
+    import QtQuick 1.0

+\brief The QML global Qt object provides useful enums and functions from Qt.
+
+\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:

+  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
+  ...

+  \enum QDeclarativeEngine::ObjectOwnership
+
+  Ownership controls whether or not QML automatically destroys the
+  QObject when the object is garbage collected by the JavaScript
+  engine.  The two ownership options are:
+
+  \value CppOwnership The object is owned by C++ code, and will
+  never be deleted by QML.  The JavaScript destroy() method cannot be
+  used on objects with CppOwnership.  This option is similar to
+  QScriptEngine::QtOwnership.
+
+  \value JavaScriptOwnership The object is owned by JavaScript.
+  When the object is returned to QML as the return value of a method
+  call or property access, QML will delete the object if there are no
+  remaining JavaScript references to it and it has 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
+  ownership of these objects is passed to JavaScript.
+
+  Calling setObjectOwnership() overrides the default ownership
+  heuristic used by QML.

+    \row \i AP
+            \i use AM/PM display. \e AP will be replaced by either "AM" or "PM".

+    in the output.
+
+For example, if the following date/time value was specified:

+    \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

+/*!
+    \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()
+*/
+
+/*!
+    \enum QDeclarativeImageProvider::ImageType

+\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.
+
+\sa {Object and List Property Types}

+    \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

+\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
+
+If instead the property had a type of QDeclarativeScriptString,
+the script itself -- \e {myObj.value = Math.max(myValue, 100)} -- would be passed to the \c script property
+and the class could choose how to handle it. Typically, the class will evaluate
+the script at some later time using a QDeclarativeExpression.
+
+\code
+QDeclarativeExpression expr(scriptString.context(), scriptString.script(), scriptStr.scopeObject());
+expr.value();
+\endcode

+\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.
