Oops.  The functionality is already there (and is exercised in the
tests), but I forgot to mention it in the docs.  Fixed in CVS.  Thanks.

This seems to refer to gtk_builder_connect_signals.  It doesn't really
do what you mean, I think.  It merely iterates over the handler names
specified in the UI description and tries to find that handler in the
application's symbol table.  So it's basically the same as
$builder->connect_signals ($data) in Perl.

This does sound interesting.  Is their enough interest to justify
putting this directly into Gtk2?
