Package Summary Overview Summary

### class:JCheckBox [NONE]
- All Implemented Interfaces: ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, SwingConstants
      public class JCheckBox
      extends JToggleButton
      implements Accessible
An implementation of a check box -- an item that can be selected or deselected, and which displays its state to the user. By convention, any number of check boxes in a group can be selected. See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for examples and information on using check boxes. 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 See Also: `JRadioButton`
