+    \class QmlContext
+    \brief The QmlContext 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 QmlContext 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 or
+    updated by calling QmlContext::setContextProperty().  The following example shows
+    a Qt model being bound to a context and then accessed from a QML file.
+
+    \code
+    QmlEngine engine;
+    QmlContext context(engine.rootContext());
+    context.setContextProperty("myModel", modelData);
+
+    QmlComponent component(&engine, "ListView { model=myModel }");
+    component.create(&context);
+    \endcode
+
+    To simplify binding and maintaining larger data sets, QObject's can be
+    added to a QmlContext.  These objects are known as the context's default
+    objects.  In this case all the properties of the QObject are
+    made available by name in the context, as though they were all individually
+    added by calling QmlContext::setContextProperty().  Changes to the property's
+    values are detected through the property's notify signal.  This method is
+    also slightly more faster than manually adding property values.
+
+    The following example has the same effect as the one above, but it is
+    achieved using a default object.
+
+    \code
+    class MyDataSet : ... {
+        ...
+        Q_PROPERTY(QAbstractItemModel *myModel READ model NOTIFY modelChanged)
+        ...
+    };
+
+    MyDataSet myDataSet;
+    QmlEngine engine;
+    QmlContext context(engine.rootContext());
+    context.addDefaultObject(&myDataSet);
+
+    QmlComponent component(&engine, "ListView { model=myModel }");
+    component.create(&context);
+    \endcode
+
+    Default objects added first take precedence over those added later.  All properties 
+    added explicitly by QmlContext::setContextProperty() take precedence over default 
+    object properties.
+
+    Contexts are hierarchal, with the \l {QmlEngine::rootContext()}{root context}
+    being created by the QmlEngine.  A component instantiated in a given context
+    has access to that context's data, as well as the data defined by its
+    ancestor contexts.  Data values (including those added implicitly by the
+    default objects) in a context override those in ancestor contexts.  Data
+    that should be available to all components instantiated by the QmlEngine
+    should be added to the \l {QmlEngine::rootContext()}{root context}.
+
+    In the following example,
+
+    \code
+    QmlEngine engine;
+    QmlContext context1(engine.rootContext());
+    QmlContext context2(&context1);
+    QmlContext context3(&context2);
+
+    context1.setContextProperty("a", 12);
+    context2.setContextProperty("b", 13);
+    context3.setContextProperty("a", 14);
+    context3.setContextProperty("c", 14);
+    \endcode
+
+    a QML component instantiated in context1 would have access to the "a" data,
+    a QML component instantiated in context2 would have access to the "a" and
+    "b" data, and a QML component instantiated in context3 would have access to
+    the "a", "b" and "c" data - although its "a" data would return 14, unlike
+    that in context1 or context2.

+    \class QmlCustomParser
+    \brief The QmlCustomParser class allows you to add new arbitrary types to QML.
+    \internal
+
+    By subclassing QmlCustomParser, you can add a parser for
+    building a particular type.
+
+    The subclass must implement compile() and setCustomData(), and define
+    itself in the meta type system with the macro:
+
+    \code
+    QML_DEFINE_CUSTOM_TYPE(Module, MajorVersion, MinorVersion, Name, TypeClass, ParserClass)
+    \endcode
+*/
+
+/*
+    \fn QByteArray QmlCustomParser::compile(const QList<QmlCustomParserProperty> & 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 QmlCustomParser::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().
+
+    The \a object will be an instance of the TypeClass specified by QML_DEFINE_CUSTOM_TYPE.

+

+    QML, properties can be assigned various different values, including basic
+    literals, property bindings, property value sources, objects and lists of
+    values.  The QmlDomValue 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
+    QmlDomDocument document;
+    QmlDomObject root = document.rootObject();
+
+    QmlDomProperty text = root.property("text");
+    if (text.value().isLiteral()) {

+    \class QmlEngine
+    \brief The QmlEngine class provides an environment for instantiating QML components.
+    \mainclass
+
+    Each QML component is instantiated in a QmlContext.  QmlContext's are
+    essential for passing data to QML components.  In QML, contexts are arranged
+    hierarchically and this hierarchy is managed by the QmlEngine.
+
+    Prior to creating any QML components, an application must have created a
+    QmlEngine to gain access to a QML context.  The following example shows how
+    to create a simple Text item.
+
+    \code
+    QmlEngine engine;
+    QmlComponent component(&engine);
+    component.setData("import Qt 4.6\nText { text: \"Hello world!\" }", QUrl());
+    QmlGraphicsItem *item = qobject_cast<QmlGraphicsItem *>(component.create());
+
+    //add item to view, etc
+    ...
+    \endcode
+
+    In this case, the Text item will be created in the engine's
+    \l {QmlEngine::rootContext()}{root context}.

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

+
+    The QML module plugin is a simple plugin interface that makes it
+    easy to add custom QML modules that can be loaded dynamically
+    into applications.
+
+    Writing a QML module plugin is achieved by subclassing this base
+    class, reimplementing the pure virtual function keys(), and
+    exporting the class with the Q_EXPORT_PLUGIN2() macro. See \l{How
+    to Create Qt Plugins} for details.
+
+    The strings returned by keys() should be the list of URIs of modules
+    that the plugin registers.
+
+    The plugin should register QML types with qmlRegisterType() when the
+    defineModule() method is called.

+    \qmlclass Script QmlScript
+    \brief The Script element provides a way to add JavaScript code snippets in QML.
+    \ingroup group_utility
+
+    The Script element is used to add convenient JavaScript "glue" methods to
+    your Qt Declarative application or component. 
+
+    An example: 
+
+    \qml
+    Script {
+        function debugMyComponent() {
+            console.log(text.text);
+            console.log(otherinterestingitem.property);
+        }
+    }
+    MouseRegion { onClicked: debugMyComponent() }
+    \endqml
+
+    \note While it is possible to use any JavaScript code within a Script element,
+    it is recommended that the code be limited to defining functions. The Script
+    element executes JavaScript as soon as it is specified, so
+    when defining a component, this may be done before the execution context is
+    fully specified.  As a result, some properties or items may not be
+    accessible. You can avoid this problem by limiting your JavaScript to
+    defining functions that are only executed later once the context is fully
+    defined.
+
+    \sa {JavaScript Blocks}
+*/
+
+/*!
+    \qmlproperty string Script::script
+    \default
+    The JavaScript code to be executed.
+*/
+
+/*!
+    \qmlproperty url Script::source
+
+    Specifies a source file containing JavaScript code. This can be used instead
+    of providing inline JavaScript code in the Script element.
