Planned maintenance has been done but it did not solve the problem. So work will continue on this and a new time for trying updates will be announced asap.
Animating with QGLWidget OpenGL
I'm a beginner with graphics programming, but I do want to program quite low-level (it must be fast, for a project).
I would like to know how to use the drawing methods in the "Hello-OpenGL"-example for animation.
I've already used these drawing methods (initalizeGL(), resizeGL() and painGL() ) to draw a few things.
My question is: how do I make this white triangle translate and rotate an x-amount per second?

You have to declare a QTimer event in your widget. Then on your TimerEvent you update your translation and rotation matrices.
Check this example http://qt-project.org/doc/qt-5.0/qtgui/openglwindow.html
right now I'm not sure but I think it's animated.
Thanks, I'll have a look at it and come back to you later..
The example link you gave is an animation.
However, it doesn't use QTimer at all.
Could you explain with code what exactly you mean with:
"Then on your TimerEvent you update your translation and rotation matrices."
This does not answer my question, could somebody please help?
