[Gtk-sharp-list] Glade signals with GtkSharp handlers

[Joe Scaduto]

Calvin,

This definitively helps in my understanding of event handlers however, I
should have mentioned that I am connecting the handlers via Glade#. 

example:

Glade.XML gxml = new Glade.XML (null,"file.glade", "window2", null);
gxml.Autoconnect (this);

So I am still not sure how I would be able to pass a string?
