Direct Known Subclasses:

JCheckBox, JRadioButton

public class JToggleButton

extends AbstractButton

implements javax.accessibility.Accessible

An implementation of a two-state button. The JRadioButton and JCheckBox classes are subclasses of this class. For information on using them see How to Use Buttons, Check Boxes, and Radio Buttons, 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 JToggleButton 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. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.
