Class GraphControl

java.lang.Object
  java.util.Observable
      org.wilmascope.control.GraphControl

public class GraphControl
extends java.util.Observable

GraphControl gives the access point or facade for the WilmaGraph drawing engine.

Nested Class Summary

class	GraphControl.Cluster the interface for clusters which are collections of nodes, note that a cluster is also a node so you can add a cluster as a member to a cluster using the GraphControl.Cluster.addNode(GraphControl.Node)method
class	GraphControl.Edge The interface for edges
class	GraphControl.ForceFacade
class	GraphControl.GraphElementFacade the basic interface common to all GraphElements
class	GraphControl.Node the interface for nodes
