Constructor & Destructor Documentation

◆ QGraphicsSceneBspTreeIndexPrivate()

QGraphicsSceneBspTreeIndexPrivate::QGraphicsSceneBspTreeIndexPrivate ( QGraphicsScene * scene )

Constructs a private scene bsp index.

Member Function Documentation

◆ _q_updateIndex()

void QGraphicsSceneBspTreeIndexPrivate::_q_updateIndex ( )

This method will update the BSP index by removing the items from the temporary unindexed list and add them in the indexedItems list.

This will also update the growingItemsBoundingRect if needed. This will update the BSP implementation as well.
