There are two kinds of dialog -- {\it modal}\ and {\it modeless}. A modal dialog
blocks program flow and user input on other windows until it is dismissed,
whereas a modeless dialog behaves more like a frame in that program flow
-continues, and input on other windows is still possible. To show a modal dialog

+Another possible special value for \arg{id} is \texttt{wxID\_NONE} meaning that
