    00027 OgreEventListeners.h  -
    00028     This file contains definatitions of all the different EventListeners.
    00029     They are all included in 1 file, due to their small size.
    00030
    00031     They all inherit from an abstract base listener called EventListener.
    00032
    00033     So far we have the following listeners:
    00034         MouseListener - handles mouse buttons clicked, pressed released,
    00035                         and mouse entered,exited,
    00036         MouseMotionListener - handles mouse move and mouse drag
    00037         ActionListener - Used for buttons, when pressed and released.
    00038         ListSelectionListener - Used when a list item is selected.
