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 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.
