Class SketchSelectionListener

java.lang.Object
  easik.sketch.util.SketchSelectionListener

All Implemented Interfaces:

java.util.EventListener, org.jgraph.event.GraphSelectionListener

public class SketchSelectionListener
extends java.lang.Object
implements org.jgraph.event.GraphSelectionListener

This class sits on the Sketch we've created and listens for selection events. Upon receiving them it updates a vector of currently selected objects (JGraphT, not JGraph cells), and allows the application to manipulate them.
