    \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.
