All Implemented Interfaces: MouseListener, MouseMotionListener, EventListener, MouseInputListener
Enclosing class:BasicMenuUI
protected class BasicMenuUI.MouseInputHandlerextends Objectimplements MouseInputListener
Instantiated and used by a menu item to handle the current menu selection
from mouse events. A MouseInputHandler processes and forwards all mouse events
to a shared instance of the MenuSelectionManager.
This class is protected so that it can be subclassed by other look and
feels to implement their own mouse handling behavior. All overridden
methods should call the parent methods so that the menu selection
is correct.
