GraphicsView: Disable BSP index building?
-
The BSP index is useful when locating items. During scene creation, it can be very costly. In my case, I build up a complex scene, and I only need the BSP index after the scene is finished.
My thought was that through setItemIndexMethod(NoIndex) I delay building up the index, and that the index is only built when I set it back to setItemIndexMethod(BspTreeIndex).
As it is, the BSP tree index starts more than 1700 timers, and (according to a measuring tool) takes up about 25 % of my total opening time.
Any ideas how to improve this (without tampering with Qt code)?

More specifically, when I click on the "Login" button, I get redirected to my profile page. I don't have any way to login there.

I don't think you can, but I'll move the post.
