-// freed. OTOH, we don't just use wxObject instead of wxTreeItemData because
-// the size of this class is critical: in any real application, each tree leaf
-// will have wxTreeItemData associated with it and number of leaves may be
-// quite big.
-//
-// Because the objects of this class are deleted by the tree, they should
-// always be allocated on the heap!
