A tree control presents information as a hierarchy, with items that may be expanded
to show further items. Items in a tree control are referenced by wxTreeItemId handles,
-which may be tested for validity by calling wxTreeItemId::IsOk.

+Please note that you \textbf{must} use wxRTTI macros
+\helpref{DECLARE\_DYNAMIC\_CLASS}{declaredynamicclass} and
+\helpref{IMPLEMENT\_DYNAMIC\_CLASS}{implementdynamicclass} if you override this

+and uses the default comparison, i.e. sorts the items alphabetically, which
+allows it optimize away the calls to the virtual function completely.
