+/*!
+    \class QGraphicsAnchorLayout
+    \brief The QGraphicsAnchorLayout class provides a layout where one can anchor widgets
+    together in Graphics View.
+    \since 4.6
+    \ingroup appearance
+    \ingroup geomanagement
+    \ingroup graphicsview-api
+
+    The anchor layout is a layout where one can specify how widgets should be placed relative to
+    each other. The specification is called an anchor, and it is set up by calling anchor().
+    Anchors are always set up between edges of an item, where the "center" is also considered to
+    be an edge. Considering this example:
+    \code
+        QGraphicsAnchorLayout *l = new QGraphicsAnchorLayout;
+        QGraphicsWidget *a = new QGraphicsWidget;
+        QGraphicsWidget *b = new QGraphicsWidget;
+        l->anchor(a, Qt::AnchorRight, b, Qt::AnchorLeft);
+    \endcode
+
+    Here is the right edge of item A anchored to the left edge of item B, with the result that
+    item B will be placed to the right of item A, with a spacing between A and B. If the
+    spacing is negative, the items will overlap to some extent. Items that are anchored are
+    automatically added to the layout, and if items are removed, all their anchors will be

+    \section1 Size Hints and Size Policies in QGraphicsLinearLayout
+    QGraphicsLinearLayout respects each item's size hints and size policies. However it does
+    not respect stretch factors currently. This might change in the future, so please refrain
+    from using stretch factors in anchor layout to avoid any future regressions.
+
+    \section1 Spacing within QGraphicsAnchorLayout
+
+    Between the items, the layout can distribute some space. If the spacing has not been
+    explicitly specified, the actual amount of space will usually be 0, but if the first edge
+    is the "opposite" of the second edge (i.e. Right is anchored to Left or vice-versa), the
+    size of the anchor will be queried from the style through the pixelMetric
+    PM_LayoutHorizontalSpacing (or PM_LayoutVerticalSpacing for vertical anchors).

+
+   The purpose of this function is to simplify the graph.
+   Simplification serves two purposes:
+   1. Reduce the number of edges in the graph, (thus the number of variables to the equation
+      solver is reduced, and the solver performs better).
+   2. Be able to do distribution of sequences of edges more intelligently (esp. with sequential
+      anchors)
+
+   It is essential that it must be possible to restore simplified anchors back to their "original"
+   form. This is done by restoreSimplifiedAnchor().
+
+   There are two types of simplification that can be done:
+   1. Sequential simplification
+      Sequential simplification means that all sequences of anchors will be merged into one single
+      anchor. Only anhcors that points in the same direction will be merged.
+   2. Parallel simplification
+      If a simplified sequential anchor is about to be inserted between two vertices in the graph
+      and there already exist an anchor between those two vertices, a parallel anchor will be
+      created that serves as a placeholder for the sequential anchor and the anchor that was
+      already between the two vertices.
+
+   The process of simplification can be described as:
+
+   1. Simplify all sequences of anchors into one anchor.
+      If no further simplification was done, go to (3)
+      - If there already exist an anchor where the sequential anchor is supposed to be inserted,
+        take that anchor out of the graph
+      - Then create a parallel anchor that holds the sequential anchor and the anchor just taken
+        out of the graph.
+   2. Go to (1)
+   3. Done
+
+
+   * Gathering sequential anchors *
+   The algorithm walks the graph in depth-first order, and only collects vertices that has two
+   edges connected to it. If the vertex does not have two edges or if it is a layout edge,
+   it will take all the previously collected vertices and try to create a simplified sequential
+   anchor representing all the previously collected vertices.
+   Once the simplified anchor is inserted, the collected list is cleared in order to find the next
+   sequence to simplify.
+   Note that there are some catches to this that are not covered by the above explanation.

+     "B, LEFT to A, RIGHT" is corrected to the above anchor.

-    Touch events occur when pressing, releasing, or moving one or more
-    touch points on a touch device (such as a touch-screen or
-    track-pad). To receive touch events, widgets have to have the
-    Qt::WA_AcceptTouchEvents attribute set and graphics items need to have
-    the \l{QGraphicsItem::setAcceptTouchEvents()}{acceptTouchEvents}
-    attribute set to true.
-
-    All touch events are of type QEvent::TouchBegin,
-    QEvent::TouchUpdate, or QEvent::TouchEnd. The touchPoints()
-    function returns a list of all touch points contained in the event.
-    Information about each touch point can be retrieved using the
-    QTouchEvent::TouchPoint class. The Qt::TouchPointState enum
-    describes the different states that a touch point may have.
-
-    Similar to QMouseEvent, Qt automatically grabs each touch point on
-    the first press inside a widget; the widget will receive all
-    updates for the touch point until it is released. Note that it is
-    possible for a widget to receive events for multiple touch points,
-    and that multiple widgets may be receiving touch events at the same
-    time.
-
-    A touch event contains a special accept flag that indicates
-    whether the receiver wants the event. By default, the event is
-    accepted. You should call ignore() if the touch event is not handled by
-    your widget. A QEvent::TouchBegin event is propagated up the parent widget
-    chain until a widget accepts it with accept(), or an event filter
-    consumes it. If the QEvent::TouchBegin event is neither accepted nor consumed,
-    then mouse events are simulated from the state of the first touch
-    point.
-
-    Reimplement QWidget::event() for widgets and QGraphicsItem::sceneEvent()
-    for items in a graphics view to receive touch events.
+    \section1 Enabling Touch Events
+
+    Touch events occur when pressing, releasing, or moving one or more touch points on a touch
+    device (such as a touch-screen or track-pad). To receive touch events, widgets have to have the
+    Qt::WA_AcceptTouchEvents attribute set and graphics items need to have the
+    \l{QGraphicsItem::setAcceptTouchEvents()}{acceptTouchEvents} attribute set to true.
+
+    Note: when using QAbstractScrollArea based widgets, you should enabled the
+    Qt::WA_AcceptTouchEvents attribute on the scroll area's
+    \l{QAbstractScrollArea::viewport()}{viewport}.
+
+    \section1 Event Delivery and Propagation
+
+    All touch events are of type QEvent::TouchBegin, QEvent::TouchUpdate, or QEvent::TouchEnd.
+    Reimplement QWidget::event() or QAbstractScrollArea::viewportEvent() for widgets and
+    QGraphicsItem::sceneEvent() for items in a graphics view to receive touch events. By default,
+    QWidget::event() translates the first non-primary touch point in a QTouchEvent into a
+    QMouseEvent. This makes it possible to enable touch events on existing widgets that do not
+    normally handle QTouchEvent. See below for information on some special considerations needed
+    when doing this.
+
+    QEvent::TouchBegin is the first touch event sent to a widget. The QEvent::TouchBegin event
+    contains a special accept flag that indicates whether the receiver wants the event. By default,
+    the event is accepted. You should call ignore() if the touch event is not handled by your
+    widget. The QEvent::TouchBegin event is propagated up the parent widget chain until a widget
+    accepts it with accept(), or an event filter consumes it. For QGraphicsItems, the
+    QEvent::TouchBegin event is propagated to items under the mouse (similar to mouse event
+    propagation for QGraphicsItems).
+
+    The QEvent::TouchUpdate and QEvent::TouchEnd events are sent to the widget or item that
+    accepted the QEvent::TouchBegin event. If the QEvent::TouchBegin event is not accepted and not
+    filtered by an event filter, then no further touch events are sent until the next
+    QEvent::TouchBegin.
+
+    The touchPoints() function returns a list of all touch points contained in the event.
+    Information about each touch point can be retrieved using the QTouchEvent::TouchPoint class.
+    The Qt::TouchPointState enum describes the different states that a touch point may have.
+
+    Similar to QMouseEvent, Qt automatically grabs each touch point on the first press inside a
+    widget; the widget will receive all updates for the touch point until it is released. Note that
+    it is possible for a widget to receive events for multiple touch points, and that multiple
+    widgets may be receiving touch events at the same time.
+
+    \section1 Touch Point Grouping
+
+    As mentioned above, it is possible that several widgets can be receiving QTouchEvents at the
+    same time. However, Qt makes sure to never send duplicate QEvent::TouchBegin events to the same
+    widget, which could theoretically happen during propagation if, for example, the user touched 2
+    separate widgets in a QGroupBox and both widgets ignored the QEvent::TouchBegin event.
+
+    To avoid this, Qt will group new touch points together using the following rules:
+
+    \list
+
+    \i When the first touch point is detected, the destination widget is determined firstly by the
+    location on screen first and secondly by the propagation rules.
+
+    \i When additional touch points are detected, Qt first looks to see if there are any active
+    touch points on any ancestor or descendent of the widget under the new touch point. If there
+    are, the new touch point is grouped with the first, and the new touch point will be sent in a
+    single QTouchEvent to the widget that handled the first touch point. (The widget under the new
+    touch point will not receive an event).
+
+    \endlist
+
+    This makes it possible for sibling widgets to handle touch events independently while making
+    sure that the sequence of QTouchEvents is always correct.
+
+    \section1 Mouse Events and the Primary Touch Point
+
+    QTouchEvent delivery is independent from that of QMouseEvent. On some windowing systems, mouse
+    events are also sent for the \l{QTouchEvent::TouchPoint::isPrimary()}{primary touch point}.
+    This means it is possible for your widget to receive both QTouchEvent and QMouseEvent for the
+    same user interaction point. You can use the QTouchEvent::TouchPoint::isPrimary() function to
+    identify the primary touch point.
+
+    Note that on some systems, it is possible to receive touch events without a primary touch
+    point. All this means is that there will be no mouse event generated for the touch points in
+    the QTouchEvent.
+
+    \section1 Caveats
+
+    \list
+
+    \i As mentioned above, enabling touch events means multiple widgets can be receiving touch
+    events simultaneously. Combined with the default QWidget::event() handling for QTouchEvents,
+    this gives you great flexibility in designing multi-touch user interfaces. Be aware of the
+    implications. For example, is is possible that the user is moving a QSlider with one finger and
+    pressing a QPushButton with another. The signals are emitted from these widgets will be
+    interleaved.
+
+    \i Recursion into the event loop using one of the exec() methods (e.g. QDialog::exec() or
+    QMenu::exec()) in a QTouchEvent event handler is not supported. Since there are multiple event
+    recipients, unexpected recursion may cause problems, including but not limited to lost events
+    and unexpected infinite recursion.
+
+    \i QTouchEvents are not affected by a \l{QWidget::grabMouse()}{mouse grab} or an
+    \l{QApplication::activePopupWidget()}{active popup widget}. The behavior of QTouchEvents is
+    undefined when opening a popup or grabbing the mouse while there are multiple active touch
+    points.
+
+    \endlist

+  \since 4.3
+  \class QScriptContext
+
+  \brief The QScriptContext class represents a Qt Script function invocation.
+
+  \ingroup script
+  \mainclass
+
+  A QScriptContext provides access to the `this' object and arguments
+  passed to a script function. You typically want to access this
+  information when you're writing a native (C++) function (see
+  QScriptEngine::newFunction()) that will be called from script
+  code. For example, when the script code
+
+  \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 0
+
+  is evaluated, a QScriptContext will be created, and the context will
+  carry the arguments as QScriptValues; in this particular case, the
+  arguments will be one QScriptValue containing the number 20.5, a second
+  QScriptValue containing the string \c{"hello"}, and a third QScriptValue
+  containing a Qt Script object.
+
+  Use argumentCount() to get the number of arguments passed to the
+  function, and argument() to get an argument at a certain index. The
+  argumentsObject() function returns a Qt Script array object
+  containing all the arguments; you can use the QScriptValueIterator
+  to iterate over its elements, or pass the array on as arguments to
+  another script function using QScriptValue::call().
+
+  Use thisObject() to get the `this' object associated with the function call,
+  and setThisObject() to set the `this' object. If you are implementing a
+  native "instance method", you typically fetch the thisObject() and access
+  one or more of its properties:
+
+  \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 1
+
+  Use isCalledAsConstructor() to determine if the function was called
+  as a constructor (e.g. \c{"new foo()"} (as constructor) or just
+  \c{"foo()"}).  When a function is called as a constructor, the
+  thisObject() contains the newly constructed object that the function
+  is expected to initialize.
+
+  Use throwValue() or throwError() to throw an exception.
+
+  Use callee() to obtain the QScriptValue that represents the function being
+  called. This can for example be used to call the function recursively.
+
+  Use parentContext() to get a pointer to the context that precedes
+  this context in the activation stack. This is mostly useful for
+  debugging purposes (e.g. when constructing some form of backtrace).
+
+  The activationObject() function returns the object that is used to
+  hold the local variables associated with this function call. You can
+  replace the activation object by calling setActivationObject(). A
+  typical usage of these functions is when you want script code to be
+  evaluated in the context of the parent context, e.g. to implement an
+  include() function:
+
+  \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 2
+
+  Use backtrace() to get a human-readable backtrace associated with
+  this context. This can be useful for debugging purposes when
+  implementing native functions. The toString() function provides a
+  string representation of the context. (QScriptContextInfo provides
+  more detailed debugging-related information about the
+  QScriptContext.)
+
+  Use engine() to obtain a pointer to the QScriptEngine that this context
+  resides in.

+/*!
+  \since 4.3
+  \class QScriptEngine
+  \reentrant
+
+  \brief The QScriptEngine class provides an environment for evaluating Qt Script code.
+
+  \ingroup script
+  \mainclass
+
+  See the \l{QtScript} documentation for information about the Qt Script language,
+  and how to get started with scripting your C++ application.
+
+  \section1 Evaluating Scripts
+
+  Use evaluate() to evaluate script code; this is the C++ equivalent
+  of the built-in script function \c{eval()}.
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 0
+
+  evaluate() returns a QScriptValue that holds the result of the
+  evaluation. The QScriptValue class provides functions for converting
+  the result to various C++ types (e.g. QScriptValue::toString()
+  and QScriptValue::toNumber()).
+
+  The following code snippet shows how a script function can be
+  defined and then invoked from C++ using QScriptValue::call():
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 1
+
+  As can be seen from the above snippets, a script is provided to the
+  engine in the form of a string. One common way of loading scripts is
+  by reading the contents of a file and passing it to evaluate():
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 2
+
+  Here we pass the name of the file as the second argument to
+  evaluate().  This does not affect evaluation in any way; the second
+  argument is a general-purpose string that is used to identify the
+  script for debugging purposes (for example, our filename will now
+  show up in any uncaughtExceptionBacktrace() involving the script).
+
+  \section1 Engine Configuration
+
+  The globalObject() function returns the \bold {Global Object}
+  associated with the script engine. Properties of the Global Object
+  are accessible from any script code (i.e. they are global
+  variables). Typically, before evaluating "user" scripts, you will
+  want to configure a script engine by adding one or more properties
+  to the Global Object:
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 3
+
+  Adding custom properties to the scripting environment is one of the
+  standard means of providing a scripting API that is specific to your
+  application. Usually these custom properties are objects created by
+  the newQObject() or newObject() functions, or constructor functions
+  created by newFunction().
+
+  \section1 Script Exceptions
+
+  evaluate() can throw a script exception (e.g. due to a syntax
+  error); in that case, the return value is the value that was thrown
+  (typically an \c{Error} object). You can check whether the
+  evaluation caused an exception by calling hasUncaughtException(). In
+  that case, you can call toString() on the error object to obtain an
+  error message. The current uncaught exception is also available
+  through uncaughtException(). You can obtain a human-readable
+  backtrace of the exception with uncaughtExceptionBacktrace().
+  Calling clearExceptions() will cause any uncaught exceptions to be
+  cleared.
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 4
+
+  The checkSyntax() function can be used to determine whether code can be
+  usefully passed to evaluate().
+
+  \section1 Script Object Creation
+
+  Use newObject() to create a standard Qt Script object; this is the
+  C++ equivalent of the script statement \c{new Object()}. You can use
+  the object-specific functionality in QScriptValue to manipulate the
+  script object (e.g. QScriptValue::setProperty()). Similarly, use
+  newArray() to create a Qt Script array object. Use newDate() to
+  create a \c{Date} object, and newRegExp() to create a \c{RegExp}
+  object.
+
+  \section1 QObject Integration
+
+  Use newQObject() to wrap a QObject (or subclass)
+  pointer. newQObject() returns a proxy script object; properties,
+  children, and signals and slots of the QObject are available as
+  properties of the proxy object. No binding code is needed because it
+  is done dynamically using the Qt meta object system.
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 5
+
+  Use qScriptConnect() to connect a C++ signal to a script function;
+  this is the Qt Script equivalent of QObject::connect().  When a
+  script function is invoked in response to a C++ signal, it can cause
+  a script exception; you can connect to the signalHandlerException()
+  signal to catch such an exception.
+
+  Use newQMetaObject() to wrap a QMetaObject; this gives you a "script
+  representation" of a QObject-based class. newQMetaObject() returns a
+  proxy script object; enum values of the class are available as
+  properties of the proxy object. You can also specify a function that
+  will be used to construct objects of the class (e.g.  when the
+  constructor is invoked from a script). For classes that have a
+  "standard" Qt constructor, Qt Script can provide a default script
+  constructor for you; see scriptValueFromQMetaObject().
+
+  See the \l{QtScript} documentation for more information on
+  the QObject integration.
+
+  \section1 Support for Custom C++ Types
+
+  Use newVariant() to wrap a QVariant. This can be used to store
+  values of custom (non-QObject) C++ types that have been registered
+  with the Qt meta-type system. To make such types scriptable, you
+  typically associate a prototype (delegate) object with the C++ type
+  by calling setDefaultPrototype(); the prototype object defines the
+  scripting API for the C++ type. Unlike the QObject integration,
+  there is no automatic binding possible here; i.e. you have to create
+  the scripting API yourself, for example by using the QScriptable
+  class.
+
+  Use fromScriptValue() to cast from a QScriptValue to another type,
+  and toScriptValue() to create a QScriptValue from another value.
+  You can specify how the conversion of C++ types is to be performed
+  with qScriptRegisterMetaType() and qScriptRegisterSequenceMetaType().
+  By default, Qt Script will use QVariant to store values of custom
+  types.
+
+  \section1 Importing Extensions
+
+  Use importExtension() to import plugin-based extensions into the
+  engine. Call availableExtensions() to obtain a list naming all the
+  available extensions, and importedExtensions() to obtain a list
+  naming only those extensions that have been imported.
+
+  Call pushContext() to open up a new variable scope, and popContext()
+  to close the current scope. This is useful if you are implementing
+  an extension that evaluates script code containing temporary
+  variable definitions (e.g. \c{var foo = 123;}) that are safe to
+  discard when evaluation has completed.
+
+  \section1 Native Functions
+
+  Use newFunction() to wrap native (C++) functions, including
+  constructors for your own custom types, so that these can be invoked
+  from script code. Such functions must have the signature
+  QScriptEngine::FunctionSignature. You may then pass the function as
+  argument to newFunction(). Here is an example of a function that
+  returns the sum of its first two arguments:
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 6
+
+  To expose this function to script code, you can set it as a property
+  of the Global Object:
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 7
+
+  Once this is done, script code can call your function in the exact
+  same manner as a "normal" script function:
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 8
+
+  \section1 Long-running Scripts
+
+  If you need to evaluate possibly long-running scripts from the main
+  (GUI) thread, you should first call setProcessEventsInterval() to
+  make sure that the GUI stays responsive. You can abort a currently
+  running script by calling abortEvaluation(). You can determine
+  whether an engine is currently running a script by calling
+  isEvaluating().
+
+  \section1 Core Debugging/Tracing Facilities
+
+  Since Qt 4.4, you can be notified of events pertaining to script
+  execution (e.g. script function calls and statement execution)
+  through the QScriptEngineAgent interface; see the setAgent()
+  function. This can be used to implement debugging and profiling of a
+  QScriptEngine.

+  Creates a QScriptValue that wraps a native (C++) function. \a fun
+  must be a C++ function with signature QScriptEngine::FunctionSignature.  \a
+  length is the number of arguments that \a fun expects; this becomes
+  the \c{length} property of the created QScriptValue.
+
+  Note that \a length only gives an indication of the number of
+  arguments that the function expects; an actual invocation of a
+  function can include any number of arguments. You can check the
+  \l{QScriptContext::argumentCount()}{argumentCount()} of the
+  QScriptContext associated with the invocation to determine the
+  actual number of arguments passed.
+
+  A \c{prototype} property is automatically created for the resulting
+  function object, to provide for the possibility that the function
+  will be used as a constructor.
+
+  By combining newFunction() and the property flags
+  QScriptValue::PropertyGetter and QScriptValue::PropertySetter, you
+  can create script object properties that behave like normal
+  properties in script code, but are in fact accessed through
+  functions (analogous to how properties work in \l{Qt's Property
+  System}). Example:
+
+  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 11
+
+  When the property \c{foo} of the script object is subsequently
+  accessed in script code, \c{getSetFoo()} will be invoked to handle
+  the access.  In this particular case, we chose to store the "real"
+  value of \c{foo} as a property of the accessor function itself; you
+  are of course free to do whatever you like in this function.
+
+  In the above example, a single native function was used to handle
+  both reads and writes to the property; the argument count is used to
+  determine if we are handling a read or write. You can also use two
+  separate functions; just specify the relevant flag
+  (QScriptValue::PropertyGetter or QScriptValue::PropertySetter) when
+  setting the property, e.g.:

+    \relates QScriptEngine
+
+    Registers the type \c{T} in the given \a engine. \a toScriptValue must
+    be a function that will convert from a value of type \c{T} to a
+    QScriptValue, and \a fromScriptValue a function that does the
+    opposite. \a prototype, if valid, is the prototype that's set on
+    QScriptValues returned by \a toScriptValue.
+
+    Returns the internal ID used by QMetaType.
+
+    You only need to call this function if you want to provide custom
+    conversion of values of type \c{T}, i.e. if the default
+    QVariant-based representation and conversion is not
+    appropriate. (Note that custom QObject-derived types also fall in
+    this category; e.g. for a QObject-derived class called MyObject,
+    you probably want to define conversion functions for MyObject*
+    that utilize QScriptEngine::newQObject() and
+    QScriptValue::toQObject().)
+
+    If you only want to define a common script interface for values of
+    type \c{T}, and don't care how those values are represented
+    (i.e. storing them in QVariants is fine), use
+    \l{QScriptEngine::setDefaultPrototype()}{setDefaultPrototype}()
+    instead; this will minimize conversion costs.
+
+    You need to declare the custom type first with
+    Q_DECLARE_METATYPE().
+
+    After a type has been registered, you can convert from a
+    QScriptValue to that type using
+    \l{QScriptEngine::fromScriptValue()}{fromScriptValue}(), and
+    create a QScriptValue from a value of that type using
+    \l{QScriptEngine::toScriptValue()}{toScriptValue}(). The engine
+    will take care of calling the proper conversion function when
+    calling C++ slots, and when getting or setting a C++ property;
+    i.e. the custom type may be used seamlessly on both the C++ side
+    and the script side.
+
+    The following is an example of how to use this function. We will
+    specify custom conversion of our type \c{MyStruct}. Here's the C++
+    type:
+
+    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 20
+
+    We must declare it so that the type will be known to QMetaType:
+
+    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 21
+
+    Next, the \c{MyStruct} conversion functions. We represent the
+    \c{MyStruct} value as a script object and just copy the properties:
+
+    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 22
+
+    Now we can register \c{MyStruct} with the engine:
+    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 23
+
+    Working with \c{MyStruct} values is now easy:
+    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 24
+
+    If you want to be able to construct values of your custom type
+    from script code, you have to register a constructor function for
+    the type. For example:
+
+    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 25
+
+    \sa qScriptRegisterSequenceMetaType(), qRegisterMetaType()
+*/
+
+/*!

+    \since 4.3
+    \relates QScriptEngine

+    QScriptEngine::scriptValueFromQMetaObject() to make enums and

+
+    Registers the sequence type \c{T} in the given \a engine. This
+    function provides conversion functions that convert between \c{T}
+    and Qt Script \c{Array} objects. \c{T} must provide a
+    const_iterator class and begin(), end() and push_back()
+    functions. If \a prototype is valid, it will be set as the

+/*!
+  \since 4.3
+  \class QScriptValue
+
+  \brief The QScriptValue class acts as a container for the Qt Script data types.
+
+  \ingroup script
+  \mainclass
+
+  QScriptValue supports the types defined in the \l{ECMA-262}
+  standard: The primitive types, which are Undefined, Null, Boolean,
+  Number, and String; and the Object type. Additionally, Qt Script
+  has built-in support for QVariant, QObject and QMetaObject.
+
+  For the object-based types (including Date and RegExp), use the
+  newT() functions in QScriptEngine (e.g. QScriptEngine::newObject())
+  to create a QScriptValue of the desired type. For the primitive types,
+  use one of the QScriptValue constructor overloads.
+
+  The methods named isT() (e.g. isBool(), isUndefined()) can be
+  used to test if a value is of a certain type. The methods named
+  toT() (e.g. toBool(), toString()) can be used to convert a
+  QScriptValue to another type. You can also use the generic
+  qscriptvalue_cast() function.
+
+  Object values have zero or more properties which are themselves
+  QScriptValues. Use setProperty() to set a property of an object, and
+  call property() to retrieve the value of a property.
+
+  \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 0
+
+  Each property can have a set of attributes; these are specified as
+  the third (optional) argument to setProperty(). The attributes of a
+  property can be queried by calling the propertyFlags() function. The
+  following code snippet creates a property that cannot be modified by
+  script code:
+
+  \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 1
+
+  If you want to iterate over the properties of a script object, use
+  the QScriptValueIterator class.
+
+  Object values have an internal \c{prototype} property, which can be
+  accessed with prototype() and setPrototype(). Properties added to a
+  prototype are shared by all objects having that prototype; this is
+  referred to as prototype-based inheritance. In practice, it means
+  that (by default) the property() function will automatically attempt
+  to look up look the property in the prototype() (and in the
+  prototype of the prototype(), and so on), if the object itself does
+  not have the requested property. Note that this prototype-based
+  lookup is not performed by setProperty(); setProperty() will always
+  create the property in the script object itself.  For more
+  information, see the \l{QtScript} documentation.
+
+  Function objects (objects for which isFunction() returns true) can
+  be invoked by calling call(). Constructor functions can be used to
+  construct new objects by calling construct().
+
+  Use equals(), strictlyEquals() and lessThan() to compare a QScriptValue
+  to another.
+
+  Object values can have custom data associated with them; see the
+  setData() and data() functions. By default, this data is not
+  accessible to scripts; it can be used to store any data you want to
+  associate with the script object. Typically this is used by custom
+  class objects (see QScriptClass) to store a C++ type that contains
+  the "native" object data.
+
+  Note that a QScriptValue for which isObject() is true only carries a
+  reference to an actual object; copying the QScriptValue will only
+  copy the object reference, not the object itself. If you want to
+  clone an object (i.e. copy an object's properties to another
+  object), you can do so with the help of a \c{for-in} statement in
+  script code, or QScriptValueIterator in C++.

-/*!
-  \since 4.3
-  \class QScriptContext
-
-  \brief The QScriptContext class represents a Qt Script function invocation.
-
-  \ingroup script
-
-
-  A QScriptContext provides access to the `this' object and arguments
-  passed to a script function. You typically want to access this
-  information when you're writing a native (C++) function (see
-  QScriptEngine::newFunction()) that will be called from script
-  code. For example, when the script code
-
-  \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 0
-
-  is evaluated, a QScriptContext will be created, and the context will
-  carry the arguments as QScriptValues; in this particular case, the
-  arguments will be one QScriptValue containing the number 20.5, a second
-  QScriptValue containing the string \c{"hello"}, and a third QScriptValue
-  containing a Qt Script object.
-
-  Use argumentCount() to get the number of arguments passed to the
-  function, and argument() to get an argument at a certain index. The
-  argumentsObject() function returns a Qt Script array object
-  containing all the arguments; you can use the QScriptValueIterator
-  to iterate over its elements, or pass the array on as arguments to
-  another script function using QScriptValue::call().
-
-  Use thisObject() to get the `this' object associated with the function call,
-  and setThisObject() to set the `this' object. If you are implementing a
-  native "instance method", you typically fetch the thisObject() and access
-  one or more of its properties:
-
-  \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 1
-
-  Use isCalledAsConstructor() to determine if the function was called
-  as a constructor (e.g. \c{"new foo()"} (as constructor) or just
-  \c{"foo()"}).  When a function is called as a constructor, the
-  thisObject() contains the newly constructed object that the function
-  is expected to initialize.
-
-  Use throwValue() or throwError() to throw an exception.
-
-  Use callee() to obtain the QScriptValue that represents the function being
-  called. This can for example be used to call the function recursively.
-
-  Use parentContext() to get a pointer to the context that precedes
-  this context in the activation stack. This is mostly useful for
-  debugging purposes (e.g. when constructing some form of backtrace).
-
-  The activationObject() function returns the object that is used to
-  hold the local variables associated with this function call. You can
-  replace the activation object by calling setActivationObject(). A
-  typical usage of these functions is when you want script code to be
-  evaluated in the context of the parent context, e.g. to implement an
-  include() function:
-
-  \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 2
-
-  Use backtrace() to get a human-readable backtrace associated with
-  this context. This can be useful for debugging purposes when
-  implementing native functions. The toString() function provides a
-  string representation of the context. (QScriptContextInfo provides
-  more detailed debugging-related information about the
-  QScriptContext.)
-
-  Use engine() to obtain a pointer to the QScriptEngine that this context
-  resides in.

-/*!
-  \since 4.3
-  \class QScriptEngine
-  \reentrant
-
-  \brief The QScriptEngine class provides an environment for evaluating Qt Script code.
-
-  \ingroup script
-
-
-  See the \l{QtScript} documentation for information about the Qt Script language,
-  and how to get started with scripting your C++ application.
-
-  \section1 Evaluating Scripts
-
-  Use evaluate() to evaluate script code; this is the C++ equivalent
-  of the built-in script function \c{eval()}.
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 0
-
-  evaluate() returns a QScriptValue that holds the result of the
-  evaluation. The QScriptValue class provides functions for converting
-  the result to various C++ types (e.g. QScriptValue::toString()
-  and QScriptValue::toNumber()).
-
-  The following code snippet shows how a script function can be
-  defined and then invoked from C++ using QScriptValue::call():
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 1
-
-  As can be seen from the above snippets, a script is provided to the
-  engine in the form of a string. One common way of loading scripts is
-  by reading the contents of a file and passing it to evaluate():
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 2
-
-  Here we pass the name of the file as the second argument to
-  evaluate().  This does not affect evaluation in any way; the second
-  argument is a general-purpose string that is used to identify the
-  script for debugging purposes (for example, our filename will now
-  show up in any uncaughtExceptionBacktrace() involving the script).
-
-  \section1 Engine Configuration
-
-  The globalObject() function returns the \bold {Global Object}
-  associated with the script engine. Properties of the Global Object
-  are accessible from any script code (i.e. they are global
-  variables). Typically, before evaluating "user" scripts, you will
-  want to configure a script engine by adding one or more properties
-  to the Global Object:
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 3
-
-  Adding custom properties to the scripting environment is one of the
-  standard means of providing a scripting API that is specific to your
-  application. Usually these custom properties are objects created by
-  the newQObject() or newObject() functions, or constructor functions
-  created by newFunction().
-
-  \section1 Script Exceptions
-
-  evaluate() can throw a script exception (e.g. due to a syntax
-  error); in that case, the return value is the value that was thrown
-  (typically an \c{Error} object). You can check whether the
-  evaluation caused an exception by calling hasUncaughtException(). In
-  that case, you can call toString() on the error object to obtain an
-  error message. The current uncaught exception is also available
-  through uncaughtException(). You can obtain a human-readable
-  backtrace of the exception with uncaughtExceptionBacktrace().
-  Calling clearExceptions() will cause any uncaught exceptions to be
-  cleared.
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 4
-
-  The checkSyntax() function can be used to determine whether code can be
-  usefully passed to evaluate().
-
-  \section1 Script Object Creation
-
-  Use newObject() to create a standard Qt Script object; this is the
-  C++ equivalent of the script statement \c{new Object()}. You can use
-  the object-specific functionality in QScriptValue to manipulate the
-  script object (e.g. QScriptValue::setProperty()). Similarly, use
-  newArray() to create a Qt Script array object. Use newDate() to
-  create a \c{Date} object, and newRegExp() to create a \c{RegExp}
-  object.
-
-  \section1 QObject Integration
-
-  Use newQObject() to wrap a QObject (or subclass)
-  pointer. newQObject() returns a proxy script object; properties,
-  children, and signals and slots of the QObject are available as
-  properties of the proxy object. No binding code is needed because it
-  is done dynamically using the Qt meta object system.
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 5
-
-  Use qScriptConnect() to connect a C++ signal to a script function;
-  this is the Qt Script equivalent of QObject::connect().  When a
-  script function is invoked in response to a C++ signal, it can cause
-  a script exception; you can connect to the signalHandlerException()
-  signal to catch such an exception.
-
-  Use newQMetaObject() to wrap a QMetaObject; this gives you a "script
-  representation" of a QObject-based class. newQMetaObject() returns a
-  proxy script object; enum values of the class are available as
-  properties of the proxy object. You can also specify a function that
-  will be used to construct objects of the class (e.g.  when the
-  constructor is invoked from a script). For classes that have a
-  "standard" Qt constructor, Qt Script can provide a default script
-  constructor for you; see scriptValueFromQMetaObject().
-
-  See the \l{QtScript} documentation for more information on
-  the QObject integration.
-
-  \section1 Support for Custom C++ Types
-
-  Use newVariant() to wrap a QVariant. This can be used to store
-  values of custom (non-QObject) C++ types that have been registered
-  with the Qt meta-type system. To make such types scriptable, you
-  typically associate a prototype (delegate) object with the C++ type
-  by calling setDefaultPrototype(); the prototype object defines the
-  scripting API for the C++ type. Unlike the QObject integration,
-  there is no automatic binding possible here; i.e. you have to create
-  the scripting API yourself, for example by using the QScriptable
-  class.
-
-  Use fromScriptValue() to cast from a QScriptValue to another type,
-  and toScriptValue() to create a QScriptValue from another value.
-  You can specify how the conversion of C++ types is to be performed
-  with qScriptRegisterMetaType() and qScriptRegisterSequenceMetaType().
-  By default, Qt Script will use QVariant to store values of custom
-  types.
-
-  \section1 Importing Extensions
-
-  Use importExtension() to import plugin-based extensions into the
-  engine. Call availableExtensions() to obtain a list naming all the
-  available extensions, and importedExtensions() to obtain a list
-  naming only those extensions that have been imported.
-
-  Call pushContext() to open up a new variable scope, and popContext()
-  to close the current scope. This is useful if you are implementing
-  an extension that evaluates script code containing temporary
-  variable definitions (e.g. \c{var foo = 123;}) that are safe to
-  discard when evaluation has completed.
-
-  \section1 Native Functions
-
-  Use newFunction() to wrap native (C++) functions, including
-  constructors for your own custom types, so that these can be invoked
-  from script code. Such functions must have the signature
-  QScriptEngine::FunctionSignature. You may then pass the function as
-  argument to newFunction(). Here is an example of a function that
-  returns the sum of its first two arguments:
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 6
-
-  To expose this function to script code, you can set it as a property
-  of the Global Object:
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 7
-
-  Once this is done, script code can call your function in the exact
-  same manner as a "normal" script function:
-
-  \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 8
-
-  \section1 Long-running Scripts
-
-  If you need to evaluate possibly long-running scripts from the main
-  (GUI) thread, you should first call setProcessEventsInterval() to
-  make sure that the GUI stays responsive. You can abort a currently
-  running script by calling abortEvaluation(). You can determine
-  whether an engine is currently running a script by calling
-  isEvaluating().
-
-  \section1 Core Debugging/Tracing Facilities
-
-  Since Qt 4.4, you can be notified of events pertaining to script
-  execution (e.g. script function calls and statement execution)
-  through the QScriptEngineAgent interface; see the setAgent()
-  function. This can be used to implement debugging and profiling of a
-  QScriptEngine.

-  are of course free to do whatever you like in this function.
-
-  In the above example, a single native function was used to handle
-  both reads and writes to the property; the argument count is used to
-  determine if we are handling a read or write. You can also use two

-    \relates QScriptEngine
-
-    Registers the type \c{T} in the given \a engine. \a toScriptValue must
-    be a function that will convert from a value of type \c{T} to a
-    QScriptValue, and \a fromScriptValue a function that does the
-    opposite. \a prototype, if valid, is the prototype that's set on
-    QScriptValues returned by \a toScriptValue.
-
-    Returns the internal ID used by QMetaType.
-
-    You only need to call this function if you want to provide custom
-    conversion of values of type \c{T}, i.e. if the default
-    QVariant-based representation and conversion is not
-    appropriate. (Note that custom QObject-derived types also fall in
-    this category; e.g. for a QObject-derived class called MyObject,
-    you probably want to define conversion functions for MyObject*
-    that utilize QScriptEngine::newQObject() and
-    QScriptValue::toQObject().)
-
-    If you only want to define a common script interface for values of
-    type \c{T}, and don't care how those values are represented
-    (i.e. storing them in QVariants is fine), use
-    \l{QScriptEngine::setDefaultPrototype()}{setDefaultPrototype}()
-    instead; this will minimize conversion costs.
-
-    You need to declare the custom type first with
-    Q_DECLARE_METATYPE().
-
-    After a type has been registered, you can convert from a
-    QScriptValue to that type using
-    \l{QScriptEngine::fromScriptValue()}{fromScriptValue}(), and
-    create a QScriptValue from a value of that type using
-    \l{QScriptEngine::toScriptValue()}{toScriptValue}(). The engine
-    will take care of calling the proper conversion function when
-    calling C++ slots, and when getting or setting a C++ property;
-    i.e. the custom type may be used seamlessly on both the C++ side
-    and the script side.
-
-    The following is an example of how to use this function. We will
-    specify custom conversion of our type \c{MyStruct}. Here's the C++
-    type:
-
-    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 20
-
-    We must declare it so that the type will be known to QMetaType:
-
-    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 21
-
-    Next, the \c{MyStruct} conversion functions. We represent the
-    \c{MyStruct} value as a script object and just copy the properties:
-
-    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 22
-
-    Now we can register \c{MyStruct} with the engine:
-    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 23
-
-    Working with \c{MyStruct} values is now easy:
-    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 24
-
-    If you want to be able to construct values of your custom type
-    from script code, you have to register a constructor function for
-    the type. For example:
-
-    \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 25
-
-    \sa qScriptRegisterSequenceMetaType(), qRegisterMetaType()

-/*!
-  \since 4.3
-  \class QScriptValue
-
-  \brief The QScriptValue class acts as a container for the Qt Script data types.
-
-  \ingroup script
-
-
-  QScriptValue supports the types defined in the \l{ECMA-262}
-  standard: The primitive types, which are Undefined, Null, Boolean,
-  Number, and String; and the Object type. Additionally, Qt Script
-  has built-in support for QVariant, QObject and QMetaObject.
-
-  For the object-based types (including Date and RegExp), use the
-  newT() functions in QScriptEngine (e.g. QScriptEngine::newObject())
-  to create a QScriptValue of the desired type. For the primitive types,
-  use one of the QScriptValue constructor overloads.
-
-  The methods named isT() (e.g. isBool(), isUndefined()) can be
-  used to test if a value is of a certain type. The methods named
-  toT() (e.g. toBool(), toString()) can be used to convert a
-  QScriptValue to another type. You can also use the generic
-  qscriptvalue_cast() function.
-
-  Object values have zero or more properties which are themselves
-  QScriptValues. Use setProperty() to set a property of an object, and
-  call property() to retrieve the value of a property.
-
-  \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 0
-
-  Each property can have a set of attributes; these are specified as
-  the third (optional) argument to setProperty(). The attributes of a
-  property can be queried by calling the propertyFlags() function. The
-  following code snippet creates a property that cannot be modified by
-  script code:
-
-  \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 1
-
-  If you want to iterate over the properties of a script object, use
-  the QScriptValueIterator class.
-
-  Object values have an internal \c{prototype} property, which can be
-  accessed with prototype() and setPrototype(). Properties added to a
-  prototype are shared by all objects having that prototype; this is
-  referred to as prototype-based inheritance. In practice, it means
-  that (by default) the property() function will automatically attempt
-  to look up look the property in the prototype() (and in the
-  prototype of the prototype(), and so on), if the object itself does
-  not have the requested property. Note that this prototype-based
-  lookup is not performed by setProperty(); setProperty() will always
-  create the property in the script object itself.  For more
-  information, see the \l{QtScript} documentation.
-
-  Function objects (objects for which isFunction() returns true) can
-  be invoked by calling call(). Constructor functions can be used to
-  construct new objects by calling construct().
-
-  Use equals(), strictlyEquals() and lessThan() to compare a QScriptValue
-  to another.
-
-  Object values can have custom data associated with them; see the
-  setData() and data() functions. By default, this data is not
-  accessible to scripts; it can be used to store any data you want to
-  associate with the script object. Typically this is used by custom
-  class objects (see QScriptClass) to store a C++ type that contains
-  the "native" object data.
-
-  Note that a QScriptValue for which isObject() is true only carries a
-  reference to an actual object; copying the QScriptValue will only
-  copy the object reference, not the object itself. If you want to
-  clone an object (i.e. copy an object's properties to another
-  object), you can do so with the help of a \c{for-in} statement in
-  script code, or QScriptValueIterator in C++.
