I found another page that mentions connect_notify(), this time a tutorial :

http://www.gtkmm.org/gtkmm2/docs/tutorial/html/ch08s07.html
Hmmm. Now that I get a small understanding of what this is all about 
(the handler only get's invoced if you use this largely undocumented 
hack): How would you like me to solve the problem?
- use connect_notify _whenever_ you connect to a button_press signal on 
a treeview (special hardcoded if within glademm)
- tell anybody to connect him/herself in the ctor (which looks like the 
most clean solution to me)
- wait for custom signal flags within glade 3.x (to request 
connect_notify on a per signal basis)
