Unsolved Finding and setting supported opengl version for QOpenGLWidget

[gde23]

Hello,

i have a ui with a QOpenGLWidget.
On my default machine it runs as it should. However on another machine (with odler graphics card) it just shows a black screen.
I guess because there the maximum opengl version that is supported is 3.1
How can i determine inside Qt which version is supported on a machine and then set the QOpenGLWidget to work with that one?

@gde23 I would be interested in finding the solution to this. I also have issues when using QOpenGLWidget on different computers with differing supported OpenGL versions. I've tried various solutions but all of which have not worked.
