QtGameEnabler and QGraphicsView

[q8phantom]

Hi

I have a simple question

Is it possible to use QtGameEnabler to improve the QGraphicsView perfomance

If yes, then how will I do that

If no, what are the best tips and tricks to improve the QGraphicsView, specially if am using QGraphicsLineItem with some blur effect, and that line have to move with the touch or mouse location with it's clicked!

Basically, that what am working on - http://www.youtube.com/watch?v=a5c3YOLc2bQ

Your help is appreciate

I have managed to do soemthing like

graphicsView->setViewPort(new GE::GameWindow);

but the perfomance sucks, as well, am facing a screen flicking issues

Do you think I should stick to QGLWidget?
