The usual problem is you tie up the EDT thread somehow (perhaps a sleep). It never gets a chance to handle the repaint event. -- Roedy Green Canadian Mind Products http://mindprod.com Responsible Development is the style of development I aspire to now.

I didn't know "Event_dispatching_thread" can be called as EDT. Tony

So when do people start using EDT to refer to "Event_dispatching_thread"? And also SSH for "Spring, Struct, Hibernate"? Tony

He probably means one or more of * Eastern Daylight Time, the civil time standard now in effect where I live. * A text/source editor for (Open)VMS. * Eau de toilette, a range of perfume strengths. * Ensconce Data Technology, maker of data-destruction products. * Estelle Development Toolkit, a suite of tools for formal specification and analysis of communicating systems. So, choose whichever of these makes the most sense in context. Oh, and there's a faint chance that he meant the Event Dispatching Thread on which most Swing activities occur. It's long been recognized that three-letter acronyms (TLA's) are in limited supply, and that most of them have already been used several times. There's a move afoot to increase the supply of TLA's by making them longer, so you can expect to see four- and five-letter TLA's any day now. -- Eric Sosman esosman(a)ieee-dot-org.invalid
