Yep, sorry, I missed that in the API documentations.

But the Gtk::Entry's "changed" signal does not pass any arguments
(Glib::SignalProxy0<void>)...
So, given the example from before:

entry1->signal_changed().connect(
        SigC::slot(*this, &PreferencesWindow::on_widget_changed));
void PreferencesWindow::on_widget_changed(void) {
  Gtk::Entry *entry = dynamic_cast<Gtk::Entry*>widgetpointer;
}

How would I get "widgetpointer" there?

Thanks for your help!
