Class Overview

Inner class of CheckboxMenuItem 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 CheckboxMenuItem class. It provides an implementation of the Java Accessibility API appropriate to checkbox menu item user-interface elements.
