Okay thank you that makes sense. What you did with a 2D data plotting sounds almost like what i am trying to do. The objects need direct interaction with each other and with the user, so the view is just a passive displayer of the interactions. While waiting I went ahead and created an alternative structure by making a generic QGraphicsView and a derived QGraphicsScene and started to test with it and it seems to be what I want for this example. Basically everything being drawn: polygons, vector arrows, text, etc. ... need to function both by themselves as entities, and be able to form groups and have interaction with other objects.
Thank you for the insight!
