It's difficult to know what's going wrong without seeing the full context in
which the method is called. Could you either post the whole program, or
email it to me if it's too big? The documentation for QWidget::update()
says:
"This function does not cause an immediate repaint; instead it schedules a
paint event for processing when Qt returns to the main event loop."
Your previous problem was related to ruby threads not working with QtRuby
calls. So is this a problem with ruby threads messing up the Qt main event
loop, and the paint event getting lost somehow?
