This is what I have found:

The widget.add_events method does not add events to widget event
queue, instead it adds event *handlers* to the widget.  It takes the
return value from a widget.signal_connect as an argument, e.g.:

window = Gtk::Window.new
handler_ref = window.signal_connect('delete_event') { Gtk.main_quit }

some_other_widget.add_events(handler_ref)

* * *

In order to get what I was aiming to, i.e. adding events to a widget
event queue (for the purpose of automated testing but probably useful
in other cases too), in C one would use the following functions from
the GTK API:

void gtk_signal_emit(GtkObject *object, guint signal_id, ...)

void gtk_signal_emit_by_name(GtkObject *object, const gchar *name, ...)

Or I think so (told you I'm just a C kid).

Unfortunately neither signal_emit and signal_emit_by_name appear to be
in the Ruby bindings.  (hint, hint ;-) )
