QGLWidget and QPainter question

[papillon]

I've read the OverPainting example but I'm a bit confused.

If I ahve a 3D object in my QGLWidget, can I use QPainter to actually paint pixels on that model, meaning painting 3D as you would do in ZBrush, for example?

if you paint on a qglwidget with qpainter you paint 2d-elements as you would paint on a glass pane lying over your screen. you're not
painting in 3D on a 3D-object.
