@clythersHackers This seems harmless enough. A little more explanation as to what this gives you in terms of BasicSceneGraph would be super helpful though.

It's a while ago so... reload context..., IIRC there's a relatively high-level DataFlowGraphicsScene with predefined behaviours which I wanted to customise myself, so I wanted to inherit directly from BasicGraphicsScene, for example drag & drop behaviours, right mouse click, etc. But trying to do that I found BasicGraphicsScene interfaces were private.
