Class SwingWorker

    java.lang.Object
      mars.simulator.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.

Constructor Summary
`SwingWorker(boolean useSwing)` Start a thread that will call the `construct` method and then exit.

Method Summary
`abstract Object` | `construct()` Compute the value to be returned by the `get` method.
`void` | `finished()` Called on the event dispatching thread (not on the worker thread) after the `construct` method has returned.
