Class ExtendedTGPanel

  • All Implemented Interfaces:
    ImageObserver, MenuContainer, Serializable, Accessible
    public class ExtendedTGPanel
extends com.touchgraph.graphlayout.TGPanel
    TGPanel contains code for drawing the graph, and storing which nodes are selected, and which ones the mouse is over. It houses methods to activate TGLayout, which performs dynamic layout. Whenever the graph is moved, or repainted, TGPanel fires listner methods on associated objects.

    Parts of this code build upon Sun's Graph Layout example. http://java.sun.com/applets/jdk/1.1/demo/GraphLayout/Graph.java
