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.

To intercept events from a tree control, use the event table macros described in \helpref{wxTreeEvent}{wxtreeevent}.

+\helpref{DECLARE\_DYNAMIC\_CLASS}{declaredynamicclass} and
+\helpref{IMPLEMENT\_DYNAMIC\_CLASS}{implementdynamicclass} if you override this
