 * An abstract adapter class for receiving graphics node key

 * convenience for creating listener objects.
 *
 * <p>Extend this class to create a <code>GraphicsNodeKeyEvent</code>
 * listener and override the methods for the events of interest. (If
 * you implement the <code>GraphicsNodeKeyListener</code> interface, you
 * have to define all of the methods in it. This abstract class
 * defines null methods for them all, so you can only have to define
 * methods for events you care about.)
