	58	\func{}{wxTreeEvent}{\param{wxEventType }{commandType}, \param{wxTreeCtrl *}{tree}, \param{const wxTreeItemId\&}{item = wxTreeItemId()}}
	59
	60	Constructor, used by wxWidgets itself only.
	61
	62
	63	\membersection{wxTreeEvent::GetKeyCode}\label{wxtreeeventgetkeycode}
	64
	65	\constfunc{int}{GetKeyCode}{}
	66
	67	Returns the key code if the event is a key event. Use
	68	\helpref{GetKeyEvent}{wxtreeeventgetkeyevent} to get the values of the
	69	modifier keys for this event (i.e. Shift or Ctrl).
	70
	71
	72	\membersection{wxTreeEvent::GetItem}\label{wxtreeeventgetitem}
	73
	74	\constfunc{wxTreeItemId}{GetItem}{}
	75
	76	Returns the item (valid for all events).
	77
	78
	79	\membersection{wxTreeEvent::GetKeyEvent}\label{wxtreeeventgetkeyevent}
	80
	81	\constfunc{const wxKeyEvent\&}{GetKeyEvent}{}
	82
	83	Returns the key event for {\tt EVT\_TREE\_KEY\_DOWN} events.
	84
	85
	86	\membersection{wxTreeEvent::GetLabel}\label{wxtreeeventgetlabel}
	87
	88	\constfunc{const wxString\&}{GetLabel}{}
	89
	90	Returns the label if the event is a begin or end edit label event.
	91
	92
	93	\membersection{wxTreeEvent::GetOldItem}\label{wxtreeeventgetolditem}
	94
	95	\constfunc{wxTreeItemId}{GetOldItem}{}
	96
	97	Returns the old item index (valid for EVT\_TREE\_ITEM\_CHANGING and CHANGED events)
	98
	99
	100	\membersection{wxTreeEvent::GetPoint}\label{wxtreeeventgetpoint}
	101
	102	\constfunc{wxPoint}{GetPoint}{}
	103
	104	Returns the position of the mouse pointer if the event is a drag or menu-context event.
	105	In both cases the position is in client coordinates - i.e. relative to the wxTreeCtrl
	106	window (so that you can pass it directly to e.g. \helpref{wxWindow::PopupMenu}{wxwindowpopupmenu}).
	107
	108
	109	\membersection{wxTreeEvent::IsEditCancelled}\label{wxtreeeventiseditcancelled}
	110
	111	\constfunc{bool}{IsEditCancelled}{}
	112
	113	Returns true if the label edit was cancelled. This should be
	114	called from within an EVT\_TREE\_END\_LABEL\_EDIT handler.
	115
	116
	117	\membersection{wxTreeEvent::SetToolTip}\label{wxtreeeventsettooltip}
	118
	119	\func{void}{SetToolTip}{\param{const wxString\&}{ tooltip}}
	120
	121	Set the tooltip for the item (valid for EVT\_TREE\_ITEM\_GETTOOLTIP events).
	122	Windows only.
