\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:
\snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 3
