But it's more than handy to just work out of the box for both 
environments. So you can even create code for 1.2 in a 2.0 environment 
and vice versa. I usually have them both installed. glademm-1.1.0 simply 
will support both glade and glade-2 and both of gtk-- and gtkmm-2 (Note: 
four combinations!!!). No branch, no fork, from a user standpoint I 
can't envision a better solution. Most user's won't notice (unless glade 
magically starts generating gtkmm-2 code once they install it in their 
path, which IMHO is not so undesirable). Perhaps a glademm-1 link should 
default to 1.2?
I'd vote for letting it die really fast.

I can understand the glademm-2 point of view, but supporting both in one 
binary (note: glademm does never link to lib(gtk/glib/gnome).so) makes 
transition of projects much easier.

And if I just don't mention? They will upgrade glademm-0.6.4 by 
glademm-1.1.0 which still supports 1.2.

The problem already existed back in the gtkmm-0.99/gtkmm-1.0/gtkmm-1.2 
days. Glademm naturally supported generating code for them all.

Wasn't this to support placeholders?

Which did not differ from button.cc/radiobutton.cc/checkbutton.cc. 
Please test my solution, it should be equivalent without duplicating code.

This work(ed) for gtk-1.2 and was sometimes used. I don't see any 
relationship to supporting '*button'. Please tell me more. What does not 
work now?
