[Vala] How to use Gtk.GestureDrag?

[Nor Jaidi Tuah <norjaidi tuah ubd edu bn>]

I'm migrating from gtk motion and button events to
gtk gestures. I tried this:

        var gesture = new Gtk.GestureDrag (widget);
        gesture.drag_begin.connect ((x, y) => { // also tried (s,x,y)
            GLib.message ("start drag");
        });
        gesture.drag_update.connect ((x, y) => {
            GLib.message ("update");
        });
        gesture.drag_end.connect ((x, y) => {
            GLib.message ("end drag");
        });
        gesture.set_propagation_phase (Gtk.PropagationPhase.BUBBLE);
        gesture.set_button (1);

That didn't work (though the old style motion and
button events worked). What did I miss?

Nice day
