-Sorts the items in the list control.
+Call this function to sorts the items in the list control. Sorting is done
+using the specified {\it fnSortCallBack} function. This function must have the
+following prototype:
 
-fn is a function which takes 3 long arguments: item1, item2, data.
+\begin{verbatim}
+int wxCALLBACK wxListCompareFunction(long item1, long item2, long sortData)
+\end{verbatim}
 
-item1 is the long data associated with a first item (NOT the index).
+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)}).
 
-item2 is the long data associated with a second item (NOT the index).
+\wxheading{Parameters}
 
-data is the same value as passed to SortItems.
+\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.}
 
-The return value is a negative number if the first item should precede the second
-item, a positive number of the second item should precede the first,
-or zero if the two items are equivalent.
+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.
 
-data is arbitrary data to be passed to the sort function.
+Please see the \helpref{listctrl sample}{samplelistctrl} for an example of
+using this function.
