Hmm, I guess you want to catch a signal when the user hits enter while 
the focus is on your entry object. I've never tried this, but as your 
Entry is a Widget, I would look at

Glib::SignalProxy1<bool,GdkEventKey*>
Gtk::Widget::signal_key_press_event()

At http://developer.gnome.org/doc/API/2.0/gdk/gdk-Event-Structures.html 
you find usefull information about the various event structures used by 
gtk and gtkmm.
