Class SwingWorker

java.lang.Object
  extended by nl.tudelft.simulation.language.swing.SwingWorker

public abstract class SwingWorker
extends Object

This is the 3rd version of SwingWorker (also known as SwingWorker 3), an abstract class that you subclass to perform GUI-related work in a dedicated thread. For instructions on and examples of using this class, see: http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html Note that the API changed slightly in the 3rd version: You must now invoke start() on the SwingWorker after creating it.
