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)?
Damn. Login button on top right of browser does not work, so my post landed here. How can I login, take ownership of the post and move it to the General forum?
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.
Interesting. I can reply to my posts as user "Asperamanca", but when I try to write a new post, I am "Guest"

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