Yes, I've been doing this in Qt/C++ for a while now, in fact I'm pretty
sure that what I described previously was Qt/C++, and not the older PyQt
interaction that I used a decade ago.

If you do use a similar system when working from C++, I'm wondering whether

No, I don't use QVTKWidget.  Tying Qt and VTK together is tricky, and I
felt that I needed total control over the QT<->VTK connection which meant
writing my own class.  I wanted something minimal so that I'd be able to
fix problems quickly.
