      Our app runs across a variety of different workstations, some without proper graphics drivers installed, so I need to check the workstation opengl version before drawing anything.

      In Qt 5.2, I had been using the following:

      QGLFormat::openGLVersionFlags().testFlag(flag)))
      

      However, QGLFormat has been deprecated moving forward.

      I'm probably missing something obvious, but in Qt 5.6 there doesn't appear to be an equivalent one-line check using QOpenGLWidget/QSurfaceFormat...

      What's the recommended method to test how high an opengl level the workstation supports using QOpenGLWidget/QSurfaceFormat?

      Thanks :)

        QSurfaceFormat fmt(this->format());
        cout << fmt.majorVersion() << "." << fmt.minorVersion() << endl;
