- public class JRadioButton
- extends JToggleButton
- implements Accessible
An implementation of a radio button -- an item that can be selected or
deselected, and which displays its state to the user.
Used with a ButtonGroup object to create a group of buttons
in which only one button at a time can be selected. (Create a ButtonGroup
object and use its add
method to include the JRadioButton objects
in the group.)
See How to Use Radio Buttons
in The Java Tutorial
for further documentation.
For the keyboard keys used by this component in the standard Look and
Feel (L&F) renditions, see the
JRadioButton 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.
