All the drawing in QWidgets is done imperatively with QPainter. Converting immediate mode painting to retained mode painting is possible, I guess... but not easy and probably full of pitfalls. Also, performance is just fine (really good actually) in practice, at least on PC-class hardware. QPainter's backend is not quite as fast as Skia, but still fast.
