Class SwingWorker

public abstract class SwingWorker
extends java.lang.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. to use the class, do final SwingWorker worker = new SwingWorker() { public Object construct() { //...code that might take a while to execute is here... return someValue; } }; worker.start(); //required for SwingWorker 3 instead of directly put the length running in the actionPerformed
