Hi,

I have created a lot of items in the scene. I also have a rectangle(QGraphicsREctItem) moving with the cursor. Whenever the rectangle moves on the items, memory usage reaches 100%, and it moves slowly, when I move the rectangle from items, it works fine. It looks as if the items were redrawn everytime the rect changes pos and intersects with them. I need the same performence while moving the rect on that items as when I have only a cursor(nothing is redrawn then). How to do that? Maybe I should create that (zooming) directly on the viewport and that map view -> scene coordinates/

Any ideas appreciated.

Thanks.

Maverick
