Any component that can be placed into a menu should implement this interface. This interface is used by MenuSelectionManager to handle selection and navigation in menu hierarchies.
Method from javax.swing.MenuElement Summary:
getComponent,   getSubElements,   menuSelectionChanged,   processKeyEvent,   processMouseEvent
Method from javax.swing.MenuElement Detail:
 public Component getComponent()
    This method should return the java.awt.Component used to paint the receiving element.
The returned component will be used to convert events and detect if an event is inside
a MenuElement's component.
 public MenuElement[] getSubElements()
    This method should return an array containing the sub-elements for the receiving menu element
 public  void menuSelectionChanged(boolean isIncluded)
    Call by the MenuSelectionManager when the
MenuElement is added or remove from
the menu selection.
 public  void processKeyEvent(KeyEvent event,
    MenuElement[] path,
    MenuSelectionManager manager)
    Process a key event.
 public  void processMouseEvent(MouseEvent event,
    MenuElement[] path,
    MenuSelectionManager manager)
    Processes a mouse event. event is a MouseEvent
with source being the receiving element's component.
path is the path of the receiving element in the menu
hierarchy including the receiving element itself.
manager is the MenuSelectionManager
for the menu hierarchy.
This method should process the MouseEvent and change
the menu selection if necessary
by using MenuSelectionManager's API
Note: you do not have to forward the event to sub-components.
This is done automatically by the MenuSelectionManager.
