Direct Known Subclasses:
  JCheckBoxMenuItem, JMenu, JRadioButtonMenuItem

    public class JMenuItem

extends AbstractButton
implements Accessible, MenuElement

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.

For further documentation and for examples, see How to Use Menus in The Java Tutorial.

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

  `JPopupMenu`, `JMenu`, `JCheckBoxMenuItem`, `JRadioButtonMenuItem`

### configurePropertiesFromAction

    protected void configurePropertiesFromAction(Action a)

  Factory method which sets the `ActionEvent` source's properties according to values from the `Action` instance. The properties which are set may differ for subclasses. By default, this method sets the same properties as `AbstractButton.configurePropertiesFromAction()`, plus `Accelerator`.

  Overrides:
    `createActionPropertyChangeListener` in class `AbstractButton`
  Parameters:
    `a` - the `Action` from which to get the properties, or `null`
