21  * An abstract adapter class for receiving graphics node mouse
22  * events. The methods in this class are empty. This class exists as
23  * convenience for creating listener objects.
24  *
25  * <p>Extend this class to create a <tt>GraphicsNodeMouseEvent</tt>
26  * listener and override the methods for the events of interest. (If
27  * you implement the <tt>GraphicsNodeMouseListener</tt> interface, you
28  * have to define all of the methods in it. This abstract class
29  * defines null methods for them all, so you can only have to define
30  * methods for events you care about.)
