An implementation of an item in a menu. A menu item is essentially a button
sitting in a list. When the user selects the "button", the action
associated with the menu item is performed. A JMenuItem
contained in a JPopupMenu performs exactly that function.
Menu items can be configured, and to some degree controlled, by
Actions. 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 documentation and for examples, see How to Use Menus 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.
