Class GraphicsNodeKeyAdapter

java.lang.Object
  extended by org.apache.batik.gvt.event.GraphicsNodeKeyAdapter
All Implemented Interfaces:
EventListener, GraphicsNodeKeyListener

public abstract class GraphicsNodeKeyAdapter
extends Object
implements GraphicsNodeKeyListener

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.)
