## Detailed Description

The QDesignerFormEditorInterface class allows you to access Qt Designer's various components.

Qt Designer's current QDesignerFormEditorInterface object holds information about all Qt Designer'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:

             QDesignerObjectInspectorInterface *objectInspector = 0;
             objectInspector = formEditor->objectInspector();

             QDesignerFormWindowManagerInterface *manager = 0;
             manager = formEditor->formWindowManager();

             objectInspector->setFormWindow(manager->formWindow(0));

QDesignerFormEditorInterface is not intended to be instantiated directly. A pointer to Qt Designer's current QDesignerFormEditorInterface object (`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 Qt Designer.

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 Qt Designer to store/retrieve persistent configuration settings. The default manager uses QSettings as the backend.

Finally, QDesignerFormEditorInterface provides the topLevel() function that returns Qt Designer's top-level widget.
