<P>

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.
