\section{\class{wxListCtrl}}\label{wxlistctrl}

A list control presents lists in a number of formats: list view, report view,
icon view and small icon view. In any case, elements are numbered from zero.

Using many of wxListCtrl is shown in the
\helpref{corresponding sample}{samplelistctrl}.

To intercept events from a list control, use the event table macros described
in \helpref{wxListEvent}{wxlistevent}.

\membersection{wxListCtrl::EditLabel}\label{wxlistctrledit}

\func{void}{EditLabel}{\param{long }{item}}

Starts editing the label of the given item. This function generates a
EVT\_LIST\_BEGIN\_LABEL\_EDIT event which can be vetoed so that no
text control will appear for in-place editing.

Sets the item text for this item.

\membersection{wxListCtrl::SetSingleStyle}\label{wxlistctrlsetsinglestyle}

\func{void}{SetSingleStyle}{\param{long }{style}, \param{const bool }{add = TRUE}}

Adds or removes a single window style.

\membersection{wxListCtrl::SetTextColour}\label{wxlistctrlsettextcolour}

\func{void}{SetTextColour}{\param{const wxColour\& }{col}}

Sets the text colour of the list control.

\membersection{wxListCtrl::SetWindowStyleFlag}\label{wxlistctrlsetwindowstyleflag}

\func{void}{SetWindowStyleFlag}{\param{long }{style}}

Sets the whole window style.

\membersection{wxListCtrl::SortItems}\label{wxlistctrlsortitems}

\func{bool}{SortItems}{\param{wxListCtrlCompare }{fnSortCallBack}, \param{long }{data}}

Call this function to sort the items in the list control. Sorting is done
using the specified {\it fnSortCallBack} function. This function must have the
following prototype:

\begin{verbatim}
int wxCALLBACK wxListCompareFunction(long item1, long item2, long sortData)
\end{verbatim}

It is called each time when the two items must be compared and should return 0
if the items are equal, negative value if the first item is less than the
second one and positive value if the first one is greater than the second one
(the same convention as used by {\tt qsort(3)}).

\wxheading{Parameters}

\docparam{item1}{client data associated with the first item ({\bf NOT} the index).}

\docparam{item2}{client data associated with the second item ({\bf NOT} the index).}

\docparam{data}{the value passed to SortItems() itself.}

Notice that the control may only be sorted on client data associated with the
items, so you {\bf must} use \helpref{SetItemData}{wxlistctrlsetitemdata} if
you want to be able to sort the items in the control.

Please see the \helpref{listctrl sample}{samplelistctrl} for an example of
using this function.

\pythonnote{wxPython uses the sortData parameter to pass the Python
function to call, so it is not available for programmer use.  Call
SortItems with a reference to a callable object that expects two
parameters.}
