Is Qt widgets deprecated?

I was at a Qt panel a few years ago and they described QtWidgets as “feature complete” (i.e. not deprecated, but no longer developed). I’m not sure they knew their audience very well. This was a computer graphics conference, which has a lot of Python2 deeply integrated to this day (Python3 is a 2020 goal!).

As your applications get more complex however you may find yourself creating custom widgets, or using PySide libraries such as PyQtGraph, who’s widgets are not available within Designer.
