\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 wxTreeItemId::IsOk.
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}.

+\membersection{wxTreeCtrl::Delete}\label{wxtreectrldelete}
+
+\func{void}{Delete}{\param{const wxTreeItemId\&}{ item}}

+\constfunc{bool}{GetBoundingRect}{\param{const wxTreeItemId\&}{ item}, \param{wxRect\& }{rect}, \param{bool }{textOnly = {\tt false}}}
+
+Retrieves the rectangle bounding the {\it item}. If {\it textOnly} is {\tt true},
+only the rectangle around the item's label will be returned, otherwise the
+item's image is also taken into account.
+
+The return value is {\tt true} if the rectangle was successfully retrieved or {\tt false}
+if it was not (in this case {\it rect} is not changed) -- for example, if the
+item is currently invisible.
+
+Notice that the rectangle coordinates are logical, not physical ones. So, for
+example, the x coordinate may be negative if the tree has a horizontal
+scrollbar and its position is not $0$.
+
+\pythonnote{The wxPython version of this method requires only the
+{\tt item} and {\tt textOnly} parameters. The return value is either a

+
+Returns the first child; call \helpref{wxTreeCtrl::GetNextChild}{wxtreectrlgetnextchild} for the next child.
+
+For this enumeration function you must pass in a `cookie' parameter
+which is opaque for the application but is necessary for the library
+to make these functions reentrant (i.e. allow more than one
+enumeration on one and the same object simultaneously). The cookie passed to
