\membersection{wxMessageDialog::\destruct{wxMessageDialog}}\label{wxmessagedialogdtor}

\func{}{\destruct{wxMessageDialog}}{\void}

Destructor.


\membersection{wxMessageDialog::ShowModal}\label{wxmessagedialogshowmodal}

\func{int}{ShowModal}{\void}

Shows the dialog, returning one of wxID\_OK, wxID\_CANCEL, wxID\_YES, wxID\_NO.


\membersection{wxMessageDialog::SetYesNoLabels}\label{wxmessagedialogsetyesnolabels}

\func{bool}{SetYesNoLabels}{\param{const wxString&}{yes},\param{const wxString&}{no}}

Overrides the default labels of the Yes and No buttons.

Notice that this function is not currently available on all platforms, so it
may return \false to indicate that the labels couldn't be changed. If it
returns \true (currently only under wxMac), the labels were set successfully.
Typically, if the function was used successfully, the main dialog message may
need to be changed, e.g.:
\begin{verbatim}
    wxMessageDialog dlg(...);
    if ( dlg.SetYesNoLabels(_("&Quit"), _("&Don't quit")) )
        dlg.SetMessage(_("What do you want to do?"));
    else // buttons have standard "Yes"/"No" values, so rephrase the question
        dlg.SetMessage(_("Do you really want to quit?"));
\end{verbatim}


\membersection{wxMessageDialog::SetYesNoCancelLabels}\label{wxmessagedialogsetyesnocancellabels}

\func{bool}{SetYesNoCancelLabels}{\param{const wxString&}{yes},\param{const wxString&}{no},\param{const wxString&}{cancel}}

Overrides the default labels of the Yes, No and Cancel buttons.

Please see the remarks in 
\helpref{SetYesNoLabels}{wxmessagedialogsetyesnolabels} documentation.


\membersection{wxMessageDialog::SetOKLabel}\label{wxmessagedialogsetyesoklabel}

\func{bool}{SetOKLabel}{\param{const wxString&}{ok}}

Overrides the default label of the OK button.

Please see the remarks in 
\helpref{SetYesNoLabels}{wxmessagedialogsetyesnolabels} documentation.


\membersection{wxMessageDialog::SetOKCancelLabels}\label{wxmessagedialogsetokcancellabels}

\func{bool}{SetOKCancelLabels}{\param{const wxString&}{ok},\param{const wxString&}{cancel}}

Overrides the default labels of the OK and Cancel buttons.

Please see the remarks in 
\helpref{SetYesNoLabels}{wxmessagedialogsetyesnolabels} documentation.


\membersection{wxMessageDialog::SetMessage}\label{wxmessagedialogsetmessage}

\func{void}{SetMessage}{\param{const wxString&}{msg}}

Sets the message shown by the dialog.


\membersection{wxMessageDialog::SetExtendedMessage}\label{wxmessagedialogsetextendedmessage}

\func{void}{SetExtendedMessage}{\param{const wxString&}{exMsg}}

Sets the extended message for the dialog: this message is usually an extension
of the short message specified in the constructor or set with 
\helpref{SetMessage}{wxmessagedialogsetmessage}. If it is set, the main message
appears highlighted -- if supported -- and this message appears beneath it in
normal font. On the platforms which don't support extended messages, it is
simply appended to the normal message with a new line separating them.
