Emitter reference.

["Alexandre Moreira" <alexandream gmail com>]

Hello, everyone.

I've been reading about Gtkmm for quite some time now, but something
just can't get inside my head.

I'm used to write software with Gtk+, and I grew very fond of the
first parameter to every signal : The Emitter pointer.

Why can't this parameter be found in any Gtkmm signal ? How do you
Gtkmm programmers overcome the lack of knowledge of the instance which
emitted the signal ?

Regards,
Alexandre Moreira.
