Hi Everybody,

I try to draw multiple polygons inside a QGraphicsPath, itself inside a QGraphicsScene.
My problem is that i have more that millions of polygons to draw. I know that in openGL/MFC, FPS is more than 10 and that's enough for my application.
Now, in Qt.... it take several seconds...

I think it's because QGraphicsPath are "intelligent" objects with a lot of interesting properties, but that also take a long time to draw if they are a lot...

But i would like to keep QGraphicsScene properties, like setSceneRect ( to delimit draw ) and scale ( to change a zoom for example ).

Can we combine QGraphicsScene / Qpainter and Scaling properties ????

thanks for your help !
Fred
