How can I use glutInitDisplayMode() in a QGLWidget, so I can get anti-aliasing?

Question

I have a QGLWidget in which openGL objects are created. I want to get better anti-aliasing than I have now by using glutInitDisplayMode(GLUT_DOUBLE | GLUT_MULTISAMPLE | GLUT_DEPTH). How can I impliment this function (in python)?

Answer 1

Qt is an application framework that implements the GUI event loop. GLUT is an application, that implements the GUI event loop. There can be only one GUI event loop in a process. Hence Qt and GLUT can not be mixed.

Just configure QGLWidget with multisampling. Create a QGLFormat instance, call setSampleBuffers(true) on it, and pass it to the QGLWidget constructor.
