Sure, you can do it when connecting callbacks to signals manually. But
how do you do this with glade (2.12)? I was searching for some
possibility to pass user data but without any success and that's why I
decided first to check the labels and later to use different
callbacks. I think it's not possible - no other glade-defined callback
in geany uses callback data either.
