Are you sure it's "delete-event" and not 'delete_event' in

$window->signal_connect("delete-event" => sub { Gtk2->main_quit; 0;});

?

For some reason Perl gtk2 developers decided to rename foo-bar in "C" into
'foo_bar' in Perl.

I always curse - since most of the info is in "C" gtk2 documentation, so I
have to remember not to forget to do the additional transaltion for the code
to work.
