Knute Johnson wrote: > Yes. <http://java.sun.com/javase/6/docs/api/javax/swing/SwingWorker.html> Read the Swing tutorial. It covers the need to do all GUI work, even construction, on the Event Dispatch Thread (EDT), the GUI thread. Don't try to wiggle out of this. It is a curiosity to me that some people look for a "way out" of having to put work not on the EDT and GUI only on the EDT. That's the way it works. Just do it right, and things work. What's there to get "out" of? How is it not simple enough the way it is? Just learn the right way. -- Lew --- * Synchronet * The Whitehouse BBS --- whitehouse.hulds.com --- check it out free usenet! --- Synchronet 3.15a-Win32 NewsLink 1.92 Time Warp of the Future BBS - telnet://time.synchro.net:24
