Hi,
I'm coming from MFC background and when I draw graphs ( realtime ) I have used the device context for drawing to an offscreen and then when finished blitted the offscreen buffer to the main screen ( BitBlt function ). Is there similar methods within QT4 to do this? Draw lines etc and do double buffering?
Kind regards,
Steve
