(see below, my version is)
$ pkg-config --modversion gtkmm-2.4
2.4.8

Hmmm. Autotools greatly vary. Can you try the CVS version of glademm, I 
still have to release again ...

These methods exist in my installation of gtkmm, which version do you 
use, which version does glademm target?

$ fgrep set_has_frame /usr/include/gtkmm-2.4/gtkmm/*.h
/usr/include/gtkmm-2.4/gtkmm/entry.h:  void set_has_frame(bool setting = 
true);

Gtk::Main::instance()->quit() is preferred (see gtkmm documentation) 
since it does not bypass local object destruction.

These files are created as a guideline. Glademm will (by design) not 
touch your program files. Please add the signal handler methods at the 
correct places (copy & paste usually is all you need).

The benefit is: You have the control how you subclass and structure your 
classes [while not every part of MAGuS (see below) is best choice it 
exercises a pretty complex OO model]

of course, see e.g. midgard.berlios.de for a huge application.
