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 :-)
