Actually what larm is asking for is very clear and does not require source code. I'm glad he was able to find another way of getting things done but I'm sure there must be some easy way of doing this.

In a standard Qt IDE installation the opengl header files are not there. If you use them in your code you will get compiling errors saying they can't be found. Even if you add the following line to the header file:

QT += opengl

So there must be something additional that is needed to allow for opengl development using the Qt IDE. I'm using Ubuntu for development.
