Package Summary Overview Summary

### class:JCheckBoxMenuItem [NONE]
- All Implemented Interfaces: ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, MenuElement, SwingConstants
      public class JCheckBoxMenuItem
      extends JMenuItem
      implements SwingConstants, Accessible
A menu item that can be selected or deselected. If selected, the menu item typically appears with a checkmark next to it. If unselected or deselected, the menu item appears without a checkmark. Like a regular menu item, a check box menu item can have either text or a graphic icon associated with it, or both. Either `isSelected`/`setSelected` or `getState`/`setState` can be used to determine/specify the menu item's selection state. The preferred methods are `isSelected` and `setSelected`, which work for all menus and buttons. The `getState` and `setState` methods exist for compatibility with other component sets. Menu items can be configured, and to some degree controlled, by `Action`s. Using an `Action` with a menu item has many benefits beyond directly configuring a menu item. 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 . For further information and examples of using check box menu items, see How to Use Menus , 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
