Hello,

I am trying to display the waveform from a wavfile on a widget using the QGraphics architecture. I will use a QGraphicsView as the widget where the waveform will be displayed.

I would like to know which classes are best and how to get the information from a wavefile to then, paint the corresponding waveform. All the wav data would have to be passed to the paint method in the QGraphicsView?

Any help with this would be greatly appreciated, thanks!
