I'm not a Qt expert, but I have just had a look through your code example and don't see anywhere you have set up a the View's main Camera. I looks like you just add a Slave camara, and that slave Camera only clears the depth buffer. I don't understand why you have gone for the set up you have, if you just need a single orthographic view then you should just set up the View's master Camera's projection and view matrix accordingly and not both with the addSlave. If you intend to have a 3D view that is overlay by the Orthographic view as a HUD, and the two are directly related then a slave Camera might be appropriate. Ask yourself, conceptually is the HUD a different View, or is it contributing to the same View.
