I don't believe this is true:  it sure looks like the callback handler 
is is defined in the xml file.  It is from this data that glademm knows 
how to create a stub callback function on the "clicked" signal.

          <signal name="clicked" handler="on_LoadButton_clicked"

Yes, but where's the code for it? libglademm considers only the contents
of the XML when it loads, so presumably it actually ignores this. Glade
the UI designer would use this for saving information for use when
generating code with glademm, or for the GTK+ C API.

  

This is in the window1_glade.cc file produced by glademm.

 LoadButton->signal_clicked().connect(SigC::slot(*this, &window1_glade::on_LoadButton_clicked));
