MenuDataProvider class

ActionScript Class Name mx.controls.menuclasses.MenuDataProvider

The MenuDataProvider class is a decorator (mix-in) class that adds functionality to the XMLNode global class. This functionality lets XML instances assigned to a Menu.dataProvider property use the MenuDataProvider methods and properties to manipulate their own data as well as the associated menu views.

Keep in mind these concepts about the MenuDataProvider class:

MenuDataProvider is a decorator (mix-in) class. You do not need to instantiate it to use it.
Menus natively accept XML as a dataProvider property value.
If a Menu class is instantiated, all XML instances in the SWF file are decorated by the MenuDataProvider class.
Only MenuDataProvider methods broadcast events to the Menu components. You can still use native XML methods, but they do not broadcast events that refresh the Menu views. To control the data model, use MenuDataProvider methods. For read-only operations like moving through the Menu hierarchy, use XML methods.
All items in the Menu component are XML objects decorated with the MenuDataProvider class.
Changes to item attributes are not reflected in the onscreen menu until redrawing occurs.
