Class java.awt.swing.ButtonGroup
java.lang.Object
|
+----java.awt.swing.ButtonGroup
- public class ButtonGroup
- extends Object
- implements Serializable
This class is used to create a multiple-exclusion scope for
a set of buttons. i.e. creating a set of buttons with the
same ButtonGroup object means that only one of those buttons
will be allowed to be "on" at a time.
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.
