[Qt-interest] BSP Tree

[Santhosh Y]

Hi,

Can anyone point me the api where BSP tree is being constructed in 
QGraphicsScene class. [\Qt\4.5.2\src\gui\graphicsview\qgraphicsscene.cpp]
OR any link which talks more on this.

Interested in knowing how the addItem() adds a node to the tree and how 
the searching is happening over the scene given a rect region.

Please give me any inputs  on this.
