The usual problem is you tie up the EDT thread somehow (perhaps a
sleep). It never gets a chance to handle the repaint event.

Oh dear. You absolutely have to understand the EDT to use Swing.

Thanks, Arne! I didn't know "Event_dispatching_thread" can be called as EDT.

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

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.
