+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.
+For all these modes, the items are stored in the control and must be added to
+it using \helpref{InsertItem}{wxlistctrlinsertitem} method.
+
+A special case of report view quite different from the other modes of the list
+control is a virtual control in which the items data (including text, images
+and attributes) is managed by the main program and is requested by the control
+itself only when needed which allows to have controls with millions of items
+without consuming much memory. To use virtual list control you must use
+\helpref{SetItemCount}{wxlistctrlsetitemcount} first and overload at least
+\helpref{OnGetItemText}{wxlistctrlongetitemtext} (and optionally
+\helpref{OnGetItemImage}{wxlistctrlongetitemimage} or \helpref{OnGetItemColumnImage}{wxlistctrlongetitemcolumnimage} and
+\helpref{OnGetItemAttr}{wxlistctrlongetitemattr}) to return the information
+about the items when the control requests it. Virtual list control can be used
+as a normal one except that no operations which can take time proportional to
+the number of items in the control happen -- this is required to allow having a
+practically infinite number of items. For example, in a multiple selection
+virtual list control, the selections won't be sent when many items are selected
+at once because this could mean iterating over all the items.
+
+Using many of wxListCtrl features 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}.

-specifies the number of columns to scroll.
+{\it dx} specifies the number of pixels to scroll. If in list view mode,

-\func{bool}{SortItems}{\param{wxListCtrlCompare }{fn}, \param{long }{data}}
+\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}
-Sorts the items in the list control.
+\docparam{item1}{client data associated with the first item ({\bf NOT} the index).}
-fn is a function which takes 3 long arguments: item1, item2, data.
+\docparam{item2}{client data associated with the second item ({\bf NOT} the index).}
-item1 is the long data associated with a first item (NOT the index).
+\docparam{data}{the value passed to SortItems() itself.}
-item2 is the long data associated with a second item (NOT the index).
+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 the same value as passed to SortItems.
+Please see the \helpref{listctrl sample}{samplelistctrl} for an example of
+using this function.
-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.
+\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.}
-data is arbitrary data to be passed to the sort function.
+\perlnote{In wxPerl the comparison function must take just two parameters;
+however, you may use a closure to achieve an effect similar to the
+SortItems third parameter.}
