All Implemented Interfaces:

public class GraphEvent
extends AbstractEvent
Contains a graph event. A GraphEvent object is passed to every GraphListener or AbstractGraphListener object which is registered to receive the "interesting" graph events using the component's addGraphListener method. (AbstractGraphListener objects implement the GraphListener interface.) Each such listener object gets a GraphEvent containing the graph event.
