Hi Alessandro,

you have to use the delete_event like this:

public class TwoWin : Gtk.Window
{
        construct
        {
                this.title = "Second window title";
                this.prepare();
        }

        private bool nascondi(Gtk.Widget w, Gdk.Event event)
        {
                this.hide();
                return false;
        }

        public void prepare()
        {
                this.delete_event += this.nascondi;

                var button = new Button.with_label("Ciao mondo");
                button.show();

                button.clicked += btn => {
                        this.title = btn.label;
                };

                this.add(button);
        }
}

I think that when you tried to use it, you forgot to change the
"nascondi" function signature according to the docs ;)

Bye,
Andrea
