> I might be misunderstanding something but last I played with it I'd say this is a fair description of a point in the past, but these days Qt Quick Controls 2 (which is bundled) is fairly well-featured, and they do keep adding new features release-by-release. It's not far from parity with Qt Widgets, and some things it does significantly better (e.g. animation or complex input handling).
