SwingWorker (Relana 1.0 API)

java.lang.Object
- eu.simuline.util.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 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.
