\section{\class{wxTreeCtrl}}\label{wxtreectrl}
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 long integer handles.
+to show further items. Items in a tree control are referenced by wxTreeItemId handles,
+which may be tested for validity by calling \helpref{wxTreeItemId::IsOk}{wxtreeitemidisok}.
To intercept events from a tree control, use the event table macros described in \helpref{wxTreeEvent}{wxtreeevent}.

+\wxheading{Win32 notes}
+
+wxTreeCtrl class uses the standard common treeview control under Win32
+implemented in the system library {\tt comctl32.dll}. Some versions of this
+library are known to have bugs with handling the tree control colours: the
+usual symptom is that the expanded items leave black (or otherwise incorrectly
+coloured) background behind them, especially for the controls using non-default background colour. The recommended solution is to upgrade the {\tt comctl32.dll}
+to a newer version: see
+\urlref{http://www.microsoft.com/downloads/release.asp?ReleaseID=11916}{http://www.microsoft.com/downloads/release.asp?ReleaseID=11916}.

+
+For this enumeration function you must pass in a `cookie' parameter

+enumeration on one and the same object simultaneously). The cookie passed to
