What's the best QT Widget to use for 2D graphics?
My requirements are:
- display lots of 2D shapes (paths, transparency, lots of primitive shapes)
- fast (can update every millisecond if possible)
- zoom-able and pan-able, but I don't want scroll bars
Right now I'm extending QWidget directly and overriding paintEvent. I've also seen QGraphicsView, GLWindow, and some other ones floating around. Which one should I use? What are the pros and cons?

Lots of shapes and navigation (zoom/pan) demands for the QGraphicsView approach, imho. It supports binary space partitioning to increase drawing speed.
Yet I don't know of what use it might be to redraw it once every millisecond.
