I'm trying to write a shader in a derived QGLWidget class, and I'd like to use GLSL 3.30, but I can't seem to use anything more recent than 1.30. I found this thread:
http://www.qtcentre.org/threads/3714...t-GLSL-version

And was able to check my GLSL version, so I know it's 1.30. Using Qt 4.8, I'm able to use OpenGL version 3.3. Is it possible to set the GLSL version as well?
