-\section{\class{wxTreeItemData}}\label{wxtreeitemdata}
-
-wxTreeItemData is some (arbitrary) user class associated with some item. The
-main advantage of having this class (compared to the old untyped interface) is
-that wxTreeItemData's are destroyed automatically by the tree and, as this
-class has virtual dtor, it means that the memory will be automatically
-freed. 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.
