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.
Menu items can be configured, and to some degree controlled, by
Action
s. Using an Action with a menu item has many benefits beyond directly configuring a menu item. Refer to
Swing Components Supporting Action
for more details, and you can find more information in
How to Use Actions
, a section in The Java Tutorial.
For further documentation and examples see
How to Use Menus
, a section in The Java Tutorial.
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. As of 1.4, support for long term storage of all JavaBeans
TM
has been added to the java.beans package. Please see
XMLEncoder
