    QtGui defautly use GDI in windows, and can be set to use OpenGL by the way below?
    A QWindow created with the QSurface::OpenGLSurface can be used in combination with QPainter and QOpenGLPaintDevice to have OpenGL hardware accelerated 2D graphics, by sacrificing some of the visual quality.

      I thought Qt used OpenGL or ANGLE on Windows, not GDI...
