public class JRadioButtonMenuItem

extends JMenuItem

implements Accessible

An implementation of a radio button menu item. A JRadioButtonMenuItem is a menu item that is part of a group of menu items in which only one item in the group can be selected. The selected item displays its selected state. Selecting it causes any other selected item to switch to the unselected state. To control the selected state of a group of radio button menu items, use a ButtonGroup object.

For further documentation and examples see How to Use Menus, a section in The Java Tutorial. For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JRadioButtonMenuItem 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 applications running the same version of Swing. A future release of Swing will provide support for long term persistence.
