Re: signals with parameters

[Armin Burgmeier <armin arbur net>]

Seems like you want to use sigc::bind like that:

hscale->signal_value_changed().connect(sigc::bind(sigc::mem_fun(*this, 
&Application::on_target_hscale_changed), hscale));

The callback function (on_target_hscale_changed), now takes a 
Gtk::HScale* parameter as last argument.
