Hello All,

I am sorry if this sounds like a dumb question, but right now my company has locked us out of getting to the Qt documentation via our ridiculous proxy. Anyway, can anyone tell me of a function or an easy way (other than resizing the widget) to force a Widget to repaint?

Thank You,
Eric Clark

widget->update(); // Repaint when the event system feels like it

widget->repaint(); // Repaint right now

99.9% of the times, you want to use the first one.
