That set of widgets could be called "QWidget". From a pure user's (the "user" here being a developer) perspective, 
whether his (q)widgets-based UI is drawn in an "imperative" way or in a "scene-graph" way is mostly irrelevent.
It becomes relevent only when there are visual glitches or performances issues.

Need to get rid of QPainter to gain performance? fine! perfect! :-) But no need to invent a new language, a new
framework, a new API... 

Besides, after so many years, QtQuickControls are still way behind QWidgets in term of functionality.

+1 definitely!
