As you say, "some" find it ugly ;-) myself included, but I'm not the only one.

This would probably be the best approach. However this is not a new project,
we're
dealing with a huge (and old) code base, such a refactoring is not (yet) an
option.
So I'm back to my initial question: can Glew be used nicely with Qt? Seems so
in my quick
test program (even using QOpenGLShaderProgram), but I'm wondering in larger
contexts.
Thanks anyway for your inputs Laszlo :-)
