Just as a side note, the unused attribute is not necessary if you omit
the parameter name, as you did.

Note that you can still use Gtk::Main::run(my_toplevel) for simplicity.
It connects signal_hide() to Gtk::Main::quit(), not delete_event.  The
window will not be hidden in response to delete_event if you return true
from the handler to stop the signal emission.
