public class JRadioButtonMenuItem extends JMenuItem implements Accessible
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: Swing is not thread safe. For more information see Swing's Threading Policy.
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 JavaBeansTM
has been added to the java.beans
package.
