[glade--] glademm auto-connect feature?

Hello!
until now i have tried some options for GUI programming with Gtk+, i have
tried C, C++, C# and Java.
But i wonder why almost every language offers a auto-connect feature for
glade but gtkmm doesn't?
I like C++ a lot and would like to go with gtkmm but with gtkmm+glademm i
have to do all the boring work by my own: define every widget in the .h
file, define every callback-function in the .h file, pull every active
widget out of the xml file and connect the signals. That's everytime the
same boring work and can be really much if the GUI have many elements. On
the other languages i have to write almost no extra line of code to do the
same thing.

Is there any reasons why glademm doesn't offer a auto-connect future like
glade did for C#, C and Java? Can i hope that auto-connect will be available
in the (near) future?

Thanks!
