OpenGL for simple graphical view?

[Daepilin]

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?

I would use the QPainter approach unless you need something in 3D (hmmm 3D tetris?). I don't think that performance will be an issue using QPainter.

You can use QPainter on a QGLWidget, it can still offer a considerable boost.

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.

Thanks to both of you:) i guess i will look into it, for now it should become 2d, but who knows how it may evolve^^ (im actually happy if get the 2d collision detection right ;))
