public class JCheckBoxMenuItem

extends JMenuItem

implements SwingConstants, Accessible

Either isSelected/setSelected or getState/setState can be used to determine/specify the menu item's selection state. (The Swing-standard methods are isSelected and setSelected. These methods work for all menus and buttons. The getState and setState methods exist for compatibility with other component sets.)

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JCheckBoxMenuItem key assignments.

Warning: serialized objects of this class will not be compatible with future swing releases. The current serialization support is appropriate for short term storage or RMI between Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.
