I do not know how to do it with QGLWidget, though.

I just found out how!!

And it is REALLY simple!
you can start yourQt application in 32bit mode by adding the argument "-visual TrueColor"
Works perfectly, all the banding problems are GONE!!
This really should be known by anybodu who is writing OpenGL games in Qt for Maemo.
