Re: [Vala] Modifying a Gtk.Entry's value on the fly

[Shem Pasamba <shemgp gmail com>]

That's actually what the documentation says here[1], at least in c. But
looking the c code that vala exports, it's passing the wrong function, so I
found workaround here[2].

So for others who may need this "feature", my code now looks something like
this:
        bool in_insert;
        [GtkCallback]
        private void on_birthday_insert_text(Gtk.Editable widget, string
text, int length, ref int position)
        {
            if (in_insert)
                return;

            in_insert = true;

            widget.insert_text("abc", 3, ref position);

            GLib.Signal.stop_emission_by_name((Gtk.Widget *) widget,
"insert_text");

            in_insert = false;
        }

Thanks for your input.
