    \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:

    \code
        QDesignerWidgetBoxInterface *widgetBox = 0:
        widgetBox = formEditor->widgetBox();

        widgetBox->load();
    \endcode

    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:

    \code
        QString originalFile = widgetBox->fileName();

        widgetBox->setFileName("myWidgetBox.xml");
        widgetBox->save();
    \endcode

    Then you can restore the original contents of the widget box by
    resetting the file name to the original file and calling load():

    \code
        widgetBox->setFileName(originalFile);
        widgetBox->load();
    \endcode

    In a similar way, you can later use your customized XML file:

    \code
        if (widgetBox->filename() != "myWidgetBox.xml") {
            widgetBox->setFileName("myWidgetBox.xml");
            widgetBox->load();
        }
    \endcode
