Direct Known Subclasses:

GraphPanel

public class TGPanel
extends JPanel

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 listener 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
