/**
* An abstract adapter class for receiving graphics node key
* events. The methods in this class are empty. This class exists as
* convenience for creating listener objects.
*
* Extend this class to create a GraphicsNodeKeyEvent
* listener and override the methods for the events of interest. (If
* you implement the GraphicsNodeKeyListener 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.)
