is there only 1 option: enable OpenGL or ANGLE ?
can i disable them All?
and what module of Qt requires them? QtGui? QGraphicsView?
if i can disable them all, can QGraphicsView or QtGui still be used?
thank you!

Where do you plan to disable OpenGL or ANGLE?
QML uses OpenGL or ANGLE (on Windows).
QtGui and QGraphicsView will work without OpenGL.
