Do QWidgets ever render using OpenGL?

For example, I have a desktop Qt built with openGL enabled (pre-built download from Qt), do the QWidgets render using opengl or software rasterization or combination of both? QPainter Documentation suggests software only. "The raster paint engine is Qt’s software rasterizer, and is used when drawing on a QImage or QWidget"

Hi
As far as i know, QWidgets are never drawn accelerated.
However QtCharts and http://doc.qt.io/qt-5/graphicsview.html
can use openGl.
