repaint widget

[yxtx1984]

What happened when call repaint()? I think it will jump to paintEvent immediately, is it right? if not, how to force the widget repaint itself immediately?

In my case, the application will not go to paintEvent immediately after repaint() or update() is called, so some fraction problem is happened.
Is it a way to force the widget repaint immeiately but not to called later.

Thanks!

what kind of problems do you have

How long does it take to get in paintEvent after you call update() or repaint() ??
Usually the paintEvent will be called in next event loop iteration, but it shouldnt be slow..you must be performing some length actions I suppose..

By the way, the program is run on the Max OS, not windows.
As to repaint(), Is something difference with different OS?

THis is my codes, the ForceRepaintAll will be called several times by signals sent by another widget when the mouseMove event happen.
void CVxTlTrackWidget::ForceRepaintAll()
{
int oldTempDraw = m_isTempDraw;
m_isTempDraw = false;
repaint();
m_isTempDraw = oldTempDraw;
}

in windows, it will go to paintEvent immediately after repaint() has run, and then go to next line: m_isTempDraw = oldTempDraw.
But in MacOS, It's different, it just go to next line of repaint(), (m_isTempDraw = oldTempDraw), and then go to the paintEvent.
