java.lang.Object | +--com.jinsight.jetchart.GraphEventListener
This class implements callback methods to handle mouse events dispatched
by the Graph class. If for some reason mouse event handling has to be changed
without losing pre-built functionalities, remove references to an instance
of this class from the Graph object and extend GraphEventListener, changing
the callback methods adequately. To remove the primary GraphEventListener,
which is created when the Graph class is instantiated, do as follows:
Graph graph=new Graph();
GraphEventListener g=graph.getGraphEventListener();
graph.removeMouseListener(g);
graph.removeMouseMotionListener(g);
Graph
,
Graph.getGraphEventListener()
