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.
