Constructor & Destructor Documentation

~CQuadTreeNode()

CQuadTreeNode::~CQuadTreeNode ( )

virtual

A virtual destructor is necessary here because CQuadTree has a list of pointers to CQuadTreeNode, some of which point to the derived class CQuadTreeLeaf. If thie destructor is not declared virtual then the CQuadTreeLeaf destructor doesn't get run in the CQuadTree destructor.
