I believe the correct way to use the QOpenGLFunction_3_1 class is actually to use protected inheritance, so that it's members are pulled into class scope and we can avoid the 'gl->' prefix. At least, this is the recommended approach for QOpenGLFunctions (http://qt-project.org/doc/qt-5/qopenglfunctions.html#details)
