+/*!
+    \class QExtensionFactory
+
+    \brief The QExtensionFactory class allows you to create a factory
+    that is able to make instances of custom extensions in Qt
+    Designer.
+
+    \inmodule QtDesigner
+
+    In \QD the extensions are not created until they are required. For
+    that reason, when implementing a custom extension, you must also
+    create a QExtensionFactory, i.e. a class that is able to make an
+    instance of your extension, and register it using \QD's \l
+    {QExtensionManager}{extension manager}.
+
+    The QExtensionManager class provides extension management
+    facilities for Qt Designer. When an extension is required, Qt
+    Designer's \l {QExtensionManager}{extension manager} will run
+    through all its registered factories calling
+    QExtensionFactory::createExtension() for each until the first one
+    that is able to create a requested extension for the selected
+    object, is found. This factory will then make an instance of the
+    extension.
+
+    There are four available types of extensions in Qt Designer:
+    QDesignerContainerExtension , QDesignerMemberSheetExtension,
+    QDesignerPropertySheetExtension and QDesignerTaskMenuExtension. Qt
+    Designer's behavior is the same whether the requested extension is
+    associated with a multi page container, a member sheet, a property
+    sheet or a task menu.
+
+    You can either create a new QExtensionFactory and reimplement the
+    QExtensionFactory::createExtension() function. For example:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_extension_default_extensionfactory.cpp 0
+
+    Or you can use an existing factory, expanding the
+    QExtensionFactory::createExtension() function to make the factory
+    able to create your extension as well. For example:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_extension_default_extensionfactory.cpp 1
+
+    For a complete example using the QExtensionFactory class, see the
+    \l {designer/taskmenuextension}{Task Menu Extension example}. The
+    example shows how to create a custom widget plugin for Qt
+    Designer, and how to to use the QDesignerTaskMenuExtension class
+    to add custom items to Qt Designer's task menu.

+/*!
+    \class QExtensionManager
+
+    \brief The QExtensionManager class provides extension management
+    facilities for Qt Designer.
+
+    \inmodule QtDesigner
+
+    In \QD the extensions are not created until they are required. For
+    that reason, when implementing an extension, you must also create
+    a QExtensionFactory, i.e a class that is able to make an instance
+    of your extension, and register it using \QD's extension manager.
+
+    The registration of an extension factory is typically made in the
+    QDesignerCustomWidgetInterface::initialize() function:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_extension_qextensionmanager.cpp 0
+
+    The QExtensionManager is not intended to be instantiated
+    directly. You can retrieve an interface to \QD's extension manager
+    using the QDesignerFormEditorInterface::extensionManager()
+    function. A pointer to \QD's current QDesignerFormEditorInterface
+    object (\c formEditor in the example above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's
+    parameter. When implementing a custom widget plugin, you must
+    subclass the QDesignerCustomWidgetInterface to expose your plugin
+    to \QD.
+
+    Then, when an extension is required, \QD's extension manager will
+    run through all its registered factories calling
+    QExtensionFactory::createExtension() for each until the first one
+    that is able to create the requested extension for the selected
+    object, is found. This factory will then make an instance of the
+    extension.
+
+    There are four available types of extensions in \QD:
+    QDesignerContainerExtension , QDesignerMemberSheetExtension,
+    QDesignerPropertySheetExtension and
+    QDesignerTaskMenuExtension. \QD's behavior is the same whether the
+    requested extension is associated with a container, a member
+    sheet, a property sheet or a task menu.
+
+    For a complete example using the QExtensionManager class, see the
+    \l {designer/taskmenuextension}{Task Menu Extension example}. The
+    example shows how to create a custom widget plugin for Qt
+    Designer, and how to to use the QDesignerTaskMenuExtension class
+    to add custom items to \QD's task menu.

+/*!
+    \class QDesignerFormEditorInterface
+
+    \brief The QDesignerFormEditorInterface class allows you to access
+    Qt Designer's various components.
+
+    \inmodule QtDesigner
+
+    \QD's current QDesignerFormEditorInterface object holds
+    information about all \QD's components: The action editor, the
+    object inspector, the property editor, the widget box, and the
+    extension and form window managers. QDesignerFormEditorInterface
+    contains a collection of functions that provides interfaces to all
+    these components. They are typically used to query (and
+    manipulate) the respective component. For example:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformeditor.cpp 0
+
+    QDesignerFormEditorInterface is not intended to be instantiated
+    directly. A pointer to \QD's current QDesignerFormEditorInterface
+    object (\c formEditor in the example above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's
+    parameter. When implementing a custom widget plugin, you must
+    subclass the QDesignerCustomWidgetInterface to expose your plugin
+    to \QD.
+
+    QDesignerFormEditorInterface also provides functions that can set
+    the action editor, property editor, object inspector and widget
+    box. These are only useful if you want to provide your own custom
+    components.
+
+    If designer is embedded in another program, one could to provide its
+    own settings manager. The manager is used by the components of \QD
+    to store/retrieve persistent configuration settings. The default
+    manager uses QSettings as the backend.
+
+    Finally, QDesignerFormEditorInterface provides the topLevel()
+    function that returns \QD's top-level widget.

+/*!
+    \class QDesignerFormWindowInterface
+
+    \brief The QDesignerFormWindowInterface class allows you to query
+    and manipulate form windows appearing in Qt Designer's workspace.
+
+    \inmodule QtDesigner
+
+    QDesignerFormWindowInterface provides information about
+    the associated form window as well as allowing its properties to be
+    altered. The interface is not intended to be instantiated
+    directly, but to provide access to \QD's current form windows
+    controlled by \QD's \l {QDesignerFormWindowManagerInterface}{form
+    window manager}.
+
+    If you are looking for the form window containing a specific
+    widget, you can use the static
+    QDesignerFormWindowInterface::findFormWindow() function:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformwindow.cpp 0
+
+    But in addition, you can access any of the current form windows
+    through \QD's form window manager: Use the
+    QDesignerFormEditorInterface::formWindowManager() function to
+    retrieve an interface to the manager. Once you have this
+    interface, you have access to all of \QD's current form windows
+    through the QDesignerFormWindowManagerInterface::formWindow()
+    function. For example:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformwindow.cpp 1
+
+    The pointer to \QD's current QDesignerFormEditorInterface object
+    (\c formEditor in the example above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's
+    parameter. When implementing a custom widget plugin, you must
+    subclass the QDesignerCustomWidgetInterface class to expose your
+    plugin to \QD.
+
+    Once you have the form window, you can query its properties. For
+    example, a plain custom widget plugin is managed by \QD only at
+    its top level, i.e. none of its child widgets can be resized in
+    \QD's workspace. But QDesignerFormWindowInterface provides you
+    with functions that enables you to control whether a widget should
+    be managed by \QD, or not:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformwindow.cpp 2
+
+    The complete list of functions concerning widget management is:
+    isManaged(), manageWidget() and unmanageWidget(). There is also
+    several associated signals: widgetManaged(), widgetRemoved(),
+    aboutToUnmanageWidget() and widgetUnmanaged().
+
+    In addition to controlling the management of widgets, you can
+    control the current selection in the form window using the
+    selectWidget(), clearSelection() and emitSelectionChanged()
+    functions, and the selectionChanged() signal.
+
+    You can also retrieve information about where the form is stored
+    using absoluteDir(), its include files using includeHints(), and
+    its layout and pixmap functions using layoutDefault(),
+    layoutFunction() and pixmapFunction(). You can find out whether
+    the form window has been modified (but not saved) or not, using
+    the isDirty() function. You can retrieve its author(), its
+    contents(), its fileName(), associated comment() and
+    exportMacro(), its mainContainer(), its features(), its grid() and
+    its resourceFiles().
+
+    The interface provides you with functions and slots allowing you
+    to alter most of this information as well. The exception is the
+    directory storing the form window. Finally, there is several
+    signals associated with changes to the information mentioned above
+    and to the form window in general.

+    \class QDesignerFormWindowCursorInterface
+
+    \brief The QDesignerFormWindowCursorInterface class allows you to
+    query and modify a form window's widget selection, and in addition
+    modify the properties of all the form's widgets.
+
+    \inmodule QtDesigner
+
+    QDesignerFormWindowCursorInterface is a convenience class that
+    provides an interface to the associated form window's text cursor;
+    it provides a collection of functions that enables you to query a
+    given form window's selection and change the selection's focus
+    according to defined modes (MoveMode) and movements
+    (MoveOperation). You can also use the interface to query the
+    form's widgets and change their properties.
+
+    The interface is not intended to be instantiated directly, but to
+    provide access to the selections and widgets of \QD's current form
+    windows. QDesignerFormWindowInterface always provides an
+    associated cursor interface. The form window for a given widget
+    can be retrieved using the static
+    QDesignerFormWindowInterface::findFormWindow() functions. For
+    example:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformwindowcursor.cpp 0
+
+    You can retrieve any of \QD's current form windows through
+    \QD's \l {QDesignerFormWindowManagerInterface}{form window
+    manager}.
+
+    Once you have a form window's cursor interface, you can check if
+    the form window has a selection at all using the hasSelection()
+    function. You can query the form window for its total
+    widgetCount() and selectedWidgetCount(). You can retrieve the
+    currently selected widget (or widgets) using the current() or
+    selectedWidget() functions.
+
+    You can retrieve any of the form window's widgets using the
+    widget() function, and check if a widget is selected using the
+    isWidgetSelected() function. You can use the setProperty()
+    function to set the selected widget's properties, and the
+    setWidgetProperty() or resetWidgetProperty() functions to modify
+    the properties of any given widget.
+
+    Finally, you can change the selection by changing the text
+    cursor's position() using the setPosition() and movePosition()
+    functions.

+    \class QDesignerFormWindowManagerInterface
+
+    \brief The QDesignerFormWindowManagerInterface class allows you to
+    manipulate the collection of form windows in Qt Designer, and
+    control Qt Designer's form editing actions.
+
+    \inmodule QtDesigner
+
+    QDesignerFormWindowManagerInterface is not intended to be
+    instantiated directly. \QD uses the form window manager to
+    control the various form windows in its workspace. You can
+    retrieve an interface to \QD's form window manager using
+    the QDesignerFormEditorInterface::formWindowManager()
+    function. For example:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformwindowmanager.cpp 0
+
+    When implementing a custom widget plugin, a pointer to \QD's
+    current QDesignerFormEditorInterface object (\c formEditor in the
+    example above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's parameter.
+    You must subclass the QDesignerCustomWidgetInterface to expose
+    your plugin to Qt Designer.
+
+    The form window manager interface provides the createFormWindow()
+    function that enables you to create a new form window which you
+    can add to the collection of form windows that the manager
+    maintains, using the addFormWindow() slot. It also provides the
+    formWindowCount() function returning the number of form windows
+    currently under the manager's control, the formWindow() function
+    returning the form window associated with a given index, and the
+    activeFormWindow() function returning the currently selected form
+    window. The removeFormWindow() slot allows you to reduce the
+    number of form windows the manager must maintain, and the
+    setActiveFormWindow() slot allows you to change the form window
+    focus in \QD's workspace.
+
+    In addition, QDesignerFormWindowManagerInterface contains a
+    collection of functions that enables you to intervene and control
+    \QD's form editing actions. All these functions return the
+    original action, making it possible to propagate the function
+    further after intervention.
+
+    Finally, the interface provides three signals which are emitted
+    when a form window is added, when the currently selected form
+    window changes, or when a form window is removed, respectively. All
+    the signals carry the form window in question as their parameter.

+
+    \brief The QDesignerObjectInspectorInterface class allows you to
+    change the focus of Qt Designer's object inspector.
+
+    \inmodule QtDesigner
+
+    You can use the QDesignerObjectInspectorInterface to change the
+    current form window selection. For example, when implementing a
+    custom widget plugin:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractobjectinspector.cpp 0
+
+    The QDesignerObjectInspectorInterface class is not intended to be
+    instantiated directly. You can retrieve an interface to \QD's
+    object inspector using the
+    QDesignerFormEditorInterface::objectInspector() function.  A
+    pointer to \QD's current QDesignerFormEditorInterface object (\c
+    formEditor in the example above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's
+    parameter. When implementing a custom widget plugin, you must
+    subclass the QDesignerCustomWidgetInterface to expose your plugin
+    to \QD.
+
+    The interface provides the core() function that you can use to
+    retrieve a pointer to \QD's current QDesignerFormEditorInterface
+    object, and the setFormWindow() function that enables you to
+    change the current form window selection.

+/*!
+    \class QDesignerPropertyEditorInterface
+
+    \brief The QDesignerPropertyEditorInterface class allows you to
+    query and manipulate the current state of Qt Designer's property
+    editor.
+
+    \inmodule QtDesigner
+
+    QDesignerPropertyEditorInterface contains a collection of
+    functions that is typically used to query the property editor for
+    its current state, and several slots manipulating it's state. The
+    interface also provide a signal, propertyChanged(), which is
+    emitted whenever a property changes in the property editor. The
+    signal's arguments are the property that changed and its new
+    value.
+
+    For example, when implementing a custom widget plugin, you can
+    connect the signal to a custom slot:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractpropertyeditor.cpp 0
+
+    Then the custom slot can check if the new value is within the
+    range we want when a specified property, belonging to a particular
+    widget, changes:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractpropertyeditor.cpp 1
+
+    The QDesignerPropertyEditorInterface class is not intended to be
+    instantiated directly. You can retrieve an interface to \QD's
+    property editor using the
+    QDesignerFormEditorInterface::propertyEditor() function. A pointer
+    to \QD's current QDesignerFormEditorInterface object (\c
+    formEditor in the examples above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's
+    parameter. When implementing a custom widget plugin, you must
+    subclass the QDesignerCustomWidgetInterface to expose your plugin
+    to \QD.
+
+    The functions accessing the property editor are the core()
+    function that you can use to retrieve an interface to the form
+    editor, the currentPropertyName() function that returns the name
+    of the currently selected property in the property editor, the
+    object() function that returns the currently selected object in
+    \QD's workspace, and the isReadOnly() function that returns true
+    if the property editor is write proteced (otherwise false).
+
+    The slots manipulating the property editor's state are the
+    setObject() slot that you can use to change the currently selected
+    object in \QD's workspace, the setPropertyValue() slot that
+    changes the value of a given property and the setReadOnly() slot
+    that control the write protection of the property editor.

+    \class QDesignerWidgetBoxInterface
+
+    \brief The QDesignerWidgetBoxInterface class allows you to control
+    the contents of Qt Designer's widget box.
+
+    \inmodule QtDesigner
+
+    QDesignerWidgetBoxInterface contains a collection of functions
+    that is typically used to manipulate the contents of \QD's widget
+    box.
+
+    \QD uses an XML file to populate its widget box. The name of that
+    file is one of the widget box's properties, and you can retrieve
+    it using the fileName() function.
+
+    QDesignerWidgetBoxInterface also provides the save() function that
+    saves the contents of the widget box in the file specified by the
+    widget box's file name property. If you have made changes to the
+    widget box, for example by dropping a widget into the widget box,
+    without calling the save() function, the original content can be
+    restored by a simple invocation of the load() function:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 0
+
+    The QDesignerWidgetBoxInterface class is not intended to be
+    instantiated directly. You can retrieve an interface to Qt
+    Designer's widget box using the
+    QDesignerFormEditorInterface::widgetBox() function. A pointer to
+    \QD's current QDesignerFormEditorInterface object (\c formEditor
+    in the example above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's
+    parameter. When implementing a custom widget plugin, you must
+    subclass the QDesignerCustomWidgetInterface to expose your plugin
+    to \QD.
+
+    If you want to save your changes, and at the same time preserve
+    the original contents, you can use the save() function combined
+    with the setFileName() function to save your changes into another
+    file. Remember to store the name of the original file first:
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 1
+
+    Then you can restore the original contents of the widget box by
+    resetting the file name to the original file and calling load():
+
+    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 2
+
+    In a similar way, you can later use your customized XML file:

+/*!
+    \class QDesignerMemberSheetExtension
+
+    \brief The QDesignerMemberSheetExtension class allows you to
+    manipulate a widget's member functions which is displayed when
+    configuring connections using Qt Designer's mode for editing
+    signals and slots.
+
+    \inmodule QtDesigner
+
+    QDesignerMemberSheetExtension is a collection of functions that is
+    typically used to query a widget's member functions, and to
+    manipulate the member functions' appearance in \QD's signals and
+    slots editing mode. For example:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 2
+
+    When implementing a custom widget plugin, a pointer to \QD's
+    current QDesignerFormEditorInterface object (\c formEditor in the
+    example above) is provided by the
+    QDesignerCustomWidgetInterface::initialize() function's parameter.
+
+    The member sheet (and any other extension), can be retrieved by
+    querying \QD's extension manager using the qt_extension()
+    function. When you want to release the extension, you only need to
+    delete the pointer.
+
+    All widgets have a default member sheet used in \QD's signals and
+    slots editing mode with the widget's member functions. But
+    QDesignerMemberSheetExtension also provides an interface for
+    creating custom member sheet extensions.
+
+    \warning \QD uses the QDesignerMemberSheetExtension to facilitate
+    the signal and slot editing mode. Whenever a connection between
+    two widgets is requested, \QD will query for the widgets' member
+    sheet extensions. If a widget has an implemented member sheet
+    extension, this extension will override the default member sheet.
+
+    To create a member sheet extension, your extension class must
+    inherit from both QObject and QDesignerMemberSheetExtension. Then,
+    since we are implementing an interface, we must ensure that it's
+    made known to the meta object system using the Q_INTERFACES()
+    macro:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 3
+
+    This enables \QD to use qobject_cast() to query for
+    supported interfaces using nothing but a QObject pointer.
+
+    In \QD the extensions are not created until they are
+    required. For that reason, when implementing a member sheet
+    extension, you must also create a QExtensionFactory, i.e a class
+    that is able to make an instance of your extension, and register
+    it using \QD's \l {QExtensionManager}{extension manager}.
+
+    When a widget's member sheet extension is required, \QD's \l
+    {QExtensionManager}{extension manager} will run through all its
+    registered factories calling QExtensionFactory::createExtension()
+    for each until the first one that is able to create a member sheet
+    extension for that widget, is found. This factory will then make
+    an instance of the extension. If no such factory is found, \QD
+    will use the default member sheet.
+
+    There are four available types of extensions in \QD:
+    QDesignerContainerExtension, QDesignerMemberSheetExtension,
+    QDesignerPropertySheetExtension and
+    QDesignerTaskMenuExtension. \QD's behavior is the same whether the
+    requested extension is associated with a multi page container, a
+    member sheet, a property sheet or a task menu.
+
+    The QExtensionFactory class provides a standard extension
+    factory, and can also be used as an interface for custom
+    extension factories. You can either create a new
+    QExtensionFactory and reimplement the
+    QExtensionFactory::createExtension() function. For example:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 4
+
+    Or you can use an existing factory, expanding the
+    QExtensionFactory::createExtension() function to make the factory
+    able to create a member sheet extension as well. For example:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 5
+
+    For a complete example using an extension class, see \l
+    {designer/taskmenuextension}{Task Menu Extension example}. The
+    example shows how to create a custom widget plugin for Qt
+    Designer, and how to to use the QDesignerTaskMenuExtension class
+    to add custom items to \QD's task menu.

+    \class QDesignerPropertySheetExtension
+
+    \brief The QDesignerPropertySheetExtension class allows you to
+    manipulate a widget's properties which is displayed in Qt
+    Designer's property editor.
+
+    \sa QDesignerDynamicPropertySheetExtension
+
+    \inmodule QtDesigner
+
+    QDesignerPropertySheetExtension provides a collection of functions that
+    are typically used to query a widget's properties, and to
+    manipulate the properties' appearance in the property editor. For
+    example:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 15
+
+    Note that if you change the value of a property using the
+    QDesignerPropertySheetExtension::setProperty() function, the undo
+    stack is not updated. To ensure that a property's value can be
+    reverted using the undo stack, you must use the
+    QDesignerFormWindowCursorInterface::setProperty() function, or its
+    buddy \l
+    {QDesignerFormWindowCursorInterface::setWidgetProperty()}{setWidgetProperty()},
+    instead.
+

+    with the Q_PROPERTY() macro). But QDesignerPropertySheetExtension
+    also provides an interface for creating custom property sheet
+    extensions.
+
+    \warning \QD uses the QDesignerPropertySheetExtension to feed its
+    property editor. Whenever a widget is selected in its workspace,
+    \QD will query for the widget's property sheet extension. If the
+    selected widget has an implemented property sheet extension, this
+    extension will override the default property sheet.

+    building the form.
+
+    \internal
+    \inmodule QtDesigner
+    \since 4.3
+
+    On saving the form, the extension is queried for a script snippet
+    to be associated with the widget while saving the UI file.
+    This script is then run after creating the widget by \l uic or
+    QUiLoader.
+
+    As opposed to \l QDesignerCustomWidgetInterface::codeTemplate(),
+    it allows for applying an internal state of the widget
+    that can be manipulated using \QD.
+
+    Such a state might for example be the contents of a custom item view widget,
+    for which an editor is provided by the QDesignerTaskMenuExtension.
+
+    While saving the form, the state is serialized as a QVariantMap of
+    \QD-supported properties, which is stored in the UI file. This is
+    handled by data() and setData().
+
+    For item view contents, there might be for example a key that determines
+    the number of items and other keys that contain the actual items following
+    a naming scheme (\c numItems, \c item1, \c item2, ...).
+
+    On saving, script() is invoked, which should return a script snippet that
+    applies the state to the widget while building the form.

+    \class QDesignerTaskMenuExtension
+    \brief The QDesignerTaskMenuExtension class allows you to add custom
+    menu entries to Qt Designer's task menu.
+    \inmodule QtDesigner
+
+    QDesignerTaskMenuExtension provides an interface for creating
+    custom task menu extensions. It is typically used to create task
+    menu entries that are specific to a plugin in \QD.
+
+    \QD uses the QDesignerTaskMenuExtension to feed its task
+    menu. Whenever a task menu is requested, \QD will query
+    for the selected widget's task menu extension.
+
+    \image taskmenuextension-example-faded.png
+
+    A task menu extension is a collection of QActions. The actions
+    appear as entries in the task menu when the plugin with the
+    specified extension is selected. The image above shows the custom
+    \gui {Edit State...} action which appears in addition to \QD's
+    default task menu entries: \gui Cut, \gui Copy, \gui Paste etc.
+
+    To create a custom task menu extension, your extension class must
+    inherit from both QObject and QDesignerTaskMenuExtension. For
+    example:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 9
+
+    Since we are implementing an interface, we must ensure that it
+    is made known to the meta-object system using the Q_INTERFACES()
+    macro. This enables \QD to use the qobject_cast() function to
+    query for supported interfaces using nothing but a QObject
+    pointer.
+
+    You must reimplement the taskActions() function to return a list
+    of actions that will be included in \QD task menu. Optionally, you
+    can reimplement the preferredEditAction() function to set the
+    action that is invoked when selecting your plugin and pressing
+    \key F2. The preferred edit action must be one of the actions
+    returned by taskActions() and, if it's not defined, pressing the
+    \key F2 key will simply be ignored.
+
+    In \QD, extensions are not created until they are required. A
+    task menu extension, for example, is created when you click the
+    right mouse button over a widget in \QD's workspace. For that
+    reason you must also construct an extension factory, using either
+    QExtensionFactory or a subclass, and register it using \QD's
+    \l {QExtensionManager}{extension manager}.
+
+    When a task menu extension is required, \QD's \l
+    {QExtensionManager}{extension manager} will run through all its
+    registered factories calling QExtensionFactory::createExtension()
+    for each until it finds one that is able to create a task menu
+    extension for the selected widget. This factory will then make an
+    instance of the extension.
+
+    There are four available types of extensions in \QD:
+    QDesignerContainerExtension, QDesignerMemberSheetExtension,
+    QDesignerPropertySheetExtension, and QDesignerTaskMenuExtension.
+    \QD's behavior is the same whether the requested extension is
+    associated with a container, a member sheet, a property sheet or a
+    task menu.
+
+    The QExtensionFactory class provides a standard extension factory,
+    and can also be used as an interface for custom extension
+    factories. You can either create a new QExtensionFactory and
+    reimplement the QExtensionFactory::createExtension() function. For
+    example:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 10
+
+    Or you can use an existing factory, expanding the
+    QExtensionFactory::createExtension() function to make the factory
+    able to create a task menu extension as well. For example:
+
+    \snippet doc/src/snippets/code/doc_src_qtdesigner.cpp 11
+
+    For a complete example using the QDesignerTaskMenuExtension class,
+    see the \l {designer/taskmenuextension}{Task Menu Extension
+    example}. The example shows how to create a custom widget plugin
+    for \QD, and how to to use the QDesignerTaskMenuExtension
+    class to add custom items to \QD's task menu.

+ *   not always be appropriate).
+ * - Page-based containers into page-based containers or simple containers if
+ *   they have just one page
+ * [Page based containers meaning here having a container extension]
+ * Morphing types are restricted to the basic Qt types. Morphing custom
+ * widgets is considered risky since they might have unmanaged layouts
+ * or the like.
+ *
+ * Requirements:
+ * - The widget must be on a non-laid out parent or in a layout managed
+ *   by Designer
+ * - Its child widgets must be non-laid out or in a layout managed
+ *   by Designer
+ * Note that child widgets can be
+ * - On the widget itself in the case of simple containers
+ * - On several pages in the case of page-based containers
+ * This is what is called 'childContainers' in the code (the widget itself
+ * or the list of container extension pages).
+ *
+ * The Morphing process encompasses:
+ * - Create a target widget and apply properties as far as applicable
+ *   If the target widget has a container extension, add a sufficient
+ *   number of pages.
+ * - Transferring the child widgets over to the new childContainers.
+ *   In the case of a managed layout on a childContainer, this is simply
+ *   set on the target childContainer, which is a new Qt 4.5
+ *   functionality.
+ * - Replace the widget itself in the parent layout

+/* -------------- NewForm dialog.
+ * Designer takes new form templates from:
+ * 1) Files located in directories specified in resources
+ * 2) Files located in directories specified as user templates
+ * 3) XML from container widgets deemed usable for form templates by the widget
+ *    database
+ * 4) XML from custom container widgets deemed usable for form templates by the
+ *    widget database
+ *
+ * The widget database provides helper functions to obtain lists of names
+ * and xml for 3,4.
+ *
+ * Fixed-size forms for embedded platforms are obtained as follows:
+ * 1) If the origin is a file:
+ *    - Check if the file exists in the subdirectory "/<width>x<height>/" of
+ *      the path (currently the case for the dialog box because the button box
+ *      needs to be positioned)
+ *    - Scale the form using the QWidgetDatabase::scaleFormTemplate routine.
+ * 2) If the origin is XML:
+ *     - Scale the form using the QWidgetDatabase::scaleFormTemplate routine.
+ *
+ * The tree widget item roles indicate which type of entry it is
+ * (TemplateNameRole = file name 1,2, ClassNameRole = class name 3,4)
