Hi all,
I am sub-classing the paintevent at the moment to create a 2D plot.
I find that I have to re-paint the whole widget every time I call an update(), as I have create a new QPainter() instance. Is there a way to update only a small part of the widget, while retaining the rest of the widget?
Thanks in advance

BTW if this is the wrong forum to post this, pls let me know.
