Actually using get_widget is what got me started on this thread.  From 
the basic example in the examples directory of libglademm-2.0.1:

#include <libglademm/xml.h>
#include <gtkmm.h>
#include <iostream>

int main (int argc, char **argv)
{
 Gtk::Main kit(argc, argv);

 //Load the Glade file and instiate its widgets:
 Glib::RefPtr<Gnome::Glade::Xml> refXml;
 try
 {
   refXml = Gnome::Glade::Xml::create("basic.glade");
 }
 catch(const Gnome::Glade::XmlError& ex)
 {
   std::cerr << ex.what() << std::endl;
   return 1;
 }
.
.
.

The problem is that the callback functions defined by glade, and 
declared in the "app_name".glade file are ignored when you instantiate 
your gui application via Glib::RefPtr<Gnome::Glade::Xml> refXml;
