All Implemented Interfaces:
  `Serializable, AccessibleComponent, AccessibleSelection`

Enclosing class:
  `MenuBar`

protected class MenuBar.AccessibleAWTMenuBar extends MenuComponent.AccessibleAWTMenuComponent
Inner class of MenuBar used to provide default support for accessibility. This class is not meant to be used directly by application developers, but is instead meant only to be subclassed by menu component developers.

This class implements accessibility support for the `MenuBar` class. It provides an implementation of the Java Accessibility API appropriate to menu bar user-interface elements.
