it's singular, not plural, when you're blocking with an id. in this case this
is the route you should go.

as far as the upper case thing goes just use the perl uc function on the text
you pass to set_text and it should work.

the following code works as expected for me.

-rm

#!/usr/bin/perl

use strict;
use warnings;

use Gtk2 '-init';

my $win = Gtk2::Window->new;
$win->set_border_width (6);
$win->signal_connect (destroy => sub { Gtk2->main_quit });

my $entry = Gtk2::Entry->new;
$win->add ($entry);

$entry->{ch} = $entry->signal_connect (changed => sub {
                print STDERR "changed\n";
                my $self = shift;
                $self->signal_handler_block ($self->{ch});
                $self->set_text (42);
                $self->signal_handler_unblock ($self->{ch});
        });

$win->show_all;
Gtk2->main;
