All Implemented Interfaces:

Runnable

public class TGLayout
extends Object
implements Runnable

TGLayout is the thread responsible for graph layout. It updates the real coordinates of the nodes in the graphEltSet object. TGPanel sends it resetDamper commands whenever the layout needs to be adjusted. After every adjustment cycle, TGLayout triggers a repaint of the TGPanel.
