Why and why? You might have to map a event coordinate to a client, but I don't
see why that would be a problem. Either way you're not wrong though. It all
depends on how much coding you want to do and how much you need to coordinate
the objects.
What might work better is trying to do it in QML first, to work it out, and
maybe even just use that? Without more details, I can't give better advice.

I actually already did that in part - that is, my parent widget is a
QGraphicsWidget, and it created a QGraphicsItemGroup and added the two
sub-widgets to it.
However, in examining this aspect it now seems like the parent widget has no
relationship to its child widgets - e.g. moving/resizing/etc the parent is not
necessarily going to moving/resizing/etc the child widgets. Or (again) am I
missing something? (Yes, the QGraphicsItemGroup is parented to the
QGraphicsWidget.)
Converting the parent QGraphicsWidget to be derived from QGraphicsItemGroup
also removes the ability to add a nice little management layer with signals and
slots; it also removes the parent widget from being able to be added to a
QGraphicsLayout.
Looking to learn,
TIA,
Ben
