<![CDATA[OpenGL for simple graphical view?]]>Hi :)

I'd like to write a little tetris fot training and i'm wondering wether i should use OpenGL for the graphical output or a standard QPainter.

Is the Qt Support for OpenGL more than just hardwareacceleration for graphics?

Alternatively, you can implement your own QQuickItem with custom geometry nodes and easily implement both 2d and 3d tetris elements by using standard openGL approaches towards constructing geometry.

I don't think that performance will be an issue using QPainter.
