Class GraphSelectionDemo

java.lang.Object
  javax.swing.tree.DefaultTreeModel
      com.jgraph.example.GraphSelectionDemo

All Implemented Interfaces:

java.io.Serializable, java.util.EventListener, javax.swing.tree.TreeModel, org.jgraph.event.GraphModelListener

public class GraphSelectionDemo
extends javax.swing.tree.DefaultTreeModel
implements org.jgraph.event.GraphModelListener

With this example you'll learn how to listen to graph selection event, program graph selections and navigate accross the graph groups. This demo is is a bit like the GraphTreeModel demo. But this time, we synchronize the graph and the tree selection with two listeners. There are two issues actually. The first is that we should disable one listener when we programatically change its selection after the other listener receives a selection event (else we would fail in infinite loops). The other issue is navigating the graph and especially its group in order to get the equivalent tree selection. Also notice that ports should be handled like a special kind of group children.
