selections).
-List box elements are numbered from zero.
+List box elements are numbered from zero. Their number is limited in
+some platforms (e.g. ca. 2000 on GTK).
A listbox callback gets an event wxEVT\_COMMAND\_LISTBOX\_SELECT for single clicks, and
-wxEVT\_COMMAND\_LISTBOX\_DOUBLE\_CLICKED for double clicks. Another way of intercepting
-double clicks is to override \helpref{wxWindow::OnDefaultAction}{wxwindowondefaultaction}.
+wxEVT\_COMMAND\_LISTBOX\_DOUBLE\_CLICKED for double clicks.

-\func{void}{Append}{\param{const wxString\& }{ item}, \param{char* }{clientData}}
+\func{void}{Append}{\param{const wxString\& }{ item}, \param{void* }{clientData}}
