>From my understanding of the documentation (trans.: I've never done this 
myself), gtk_signal_connect_object calls a signal handler with an object other 
than the one that generated the signal. So when `button' receives a `clicked' 
signal, the signal handler is called with `window' as the current object 
instead of `button'. The last parameter above isn't the user data.

However, I don't know why it doesn't work in your code. Are you sure you're 
using gtk_signal_connect_object and not gtk_signal_connect?
