This class represents a dialog that shows a list of strings, and allows the
user to select one. Double-clicking on a list item is equivalent to
single-clicking and then pressing OK.

\param{const wxString\& }{caption}, \param{const wxArrayString\& }{choices},\rtfsp
\param{void**}{ clientData = NULL}, \param{long }{style = wxCHOICEDLG\_STYLE},\rtfsp
\param{const wxPoint\& }{pos = wxDefaultPosition}}

Constructor, taking an array of wxString choices and optional client data.

\wxheading{Parameters}

\docparam{parent}{Parent window.}

\docparam{message}{Message to show on the dialog.}

\docparam{caption}{The dialog caption.}

\docparam{n}{The number of choices.}

\docparam{choices}{An array of strings, or a string list, containing the choices.}

\docparam{clientData}{An array of client data to be associated with the items.
See \helpref{GetSelectionClientData}{wxsinglechoicedialoggetselectionclientdata}.}

\docparam{style}{A dialog style (bitlist) containing flags chosen from standard
dialog styles and the following:

\twocolwidtha{5cm}
\begin{twocollist}
\twocolitem{{\bf wxOK}}{Show an OK button.}
\twocolitem{{\bf wxCANCEL}}{Show a Cancel button.}
\twocolitem{{\bf wxCENTRE}}{Centre the message. Not Windows.}
\end{twocollist}
The default value is equivalent to {\bf wxDEFAULT\_DIALOG\_STYLE \pipe wxRESIZE\_BORDER \pipe wxOK \pipe wxCANCEL \pipe wxCENTRE}.
}

\docparam{pos}{Dialog position. Not Windows.}

\wxheading{Remarks}

Use \helpref{wxSingleChoiceDialog::ShowModal}{wxsinglechoicedialogshowmodal} to show the dialog.

\pythonnote{For Python the two parameters {\tt n} and {\tt choices} are collapsed
into a single parameter {\tt choices} which is expected to be a Python
list of strings.}

\perlnote{In wxPerl there is just an array reference in place of {\tt n}
and {\tt choices}, and the client data array, if present, must have the
same length as the choices array.}

\membersection{wxSingleChoiceDialog::GetSelection}\label{wxsinglechoicedialoggetselection}

\constfunc{int}{GetSelection}{\void}

Returns the index of selected item.

\membersection{wxSingleChoiceDialog::GetSelectionClientData}\label{wxsinglechoicedialoggetselectionclientdata}

\membersection{wxSingleChoiceDialog::GetStringSelection}\label{wxsinglechoicedialoggetstringselection}

\constfunc{wxString}{GetStringSelection}{\void}

Returns the selected string.

\membersection{wxSingleChoiceDialog::SetSelection}\label{wxsinglechoicedialogsetselection}

\constfunc{void}{SetSelection}{\param{int}{ selection}}

Sets the index of the initially selected item.
