  • All Implemented Interfaces:

    BasicMenuUI

    protected class BasicMenuUI.MouseInputHandler
    extends Object
    implements 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.
