[Gtk-sharp-list] How do I keep main window from closing?

I have a TextView on my main window. I don't want to be able to close the
main window if the text in this TextView has been modified but not yet saved
to disk. I realize I can check the control's Buffer.Modified property and
that this should likely be done in the main windows's OnDeleteEvent handler
but I don't know how to make this work. I took a WAG and tried this...
protected void OnDeleteEvent (object sender, DeleteEventArgs a)
MessageDialog WarningMesgDlg = new MessageDialog (this,
ButtonsType.YesNo, "Abandon changes?");
if ((!docTextView.Buffer.Modified) || (WarningMesgDlg.Run() == (int)
a.RetVal = true;
... but the main window closes even though the Modified property is true and
I answer "no" to the dialog's question, "Abandon changes?". Can someone
shed some light on how I should go about this? Thanks!
