Drawing grids efficiently in QGraphicsScene

[arjunasd]

Hi

Did you find an efficient way to draw the grid?

I am running into the same issue too? My grid is very slow. Also when I zoomIn or zoomOut, I have many wide irregular gaps between grids.

Thanks
Arjun

Hello, I know this thread is so old, but I think I can contribute. Recently I had to do something similar and I got the same problem, eficiency, I develop a simple solution with a simple technique that uses a bitmap to draw all, is so fast and efficient, the explanation is in my website Creación de grilla de forma eficiente en QGraphicsView/QGraphicsScene but is spanish, if you think that you can exploit this, then visit it.
