# Class JToggleButton

java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.AbstractButton
javax.swing.JToggleButton

All Implemented Interfaces:
  `ImageObserver`, `ItemSelectable`, `MenuContainer`, `Serializable`, `Accessible`, `SwingConstants`

Direct Known Subclasses:
  `JCheckBox`, `JRadioButton`

@JavaBean(defaultProperty="UIClassID", description="An implementation of a two-state button.") public class JToggleButton extends AbstractButton implements 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.

Buttons can be configured, and to some degree controlled, by `Action`s. Using an `Action` with a button has many benefits beyond directly configuring a button. 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.

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 JavaBeans has been added to the `java.beans` package. Please see `XMLEncoder`.

Since:
  1.2
