[PyQt] Error in example script

[Mads Ipsen]

The OpenGL example script 'samplebuffers.py' will fail when reaching the 
blocks:

'    if not QtOpenGL.QGLFormat.hasOpenGL():
        QMessageBox.information(None, "OpenGL samplebuffers",
                "This system does not support OpenGL.")
        sys.exit(0)

and

    if not widget.format().sampleBuffers():
        QMessageBox.information(None, "OpenGL samplebuffers",
                "This system does not have sample buffer support.")
        sys.exit(0)

The calls to the static method 'QMessageBox.information' should be 
replaced by

  QtGui.QMessageBox.information

Best regards,

Mads
