Hello, I am looking 
    if ($type eq 'bitmap') {
        my $bg = ($c->itemconfigure(qw/current -background/))[4];
        if (defined $bg) {
            $iinfo->{restore_cmd} = "\$c->itemconfigure('current',
                -background => '$bg');";
        } else {
            $iinfo->{restore_cmd} = "\$c->itemconfigure('current',
                -background => undef);";
        }
        $c->itemconfigure(qw/current -background SteelBlue2/);
        return;
    }

and I simply do not understand the construct 
my $bg = ($c->itemconfigure(qw/current -background/))[4];

What is 4?? I thought itemconfigure was used to set a property but seemingly it is being used here to retrieve a value? Thanks for the wisdom
