in thread perl/gtk2 simplelist

(Minor nit: it's not a command. It's accessing an array reference. Read up on Perl data structures.)

$slist->{data} is an array reference of other array references (the "rows" in the list) each item of which is a piece of data (the "columns" in each row). Fiddle about with this:

for my $row (@{$slist->{data}}) { print "Row:\n"; for my $col (@{$row}) { print " $col\n"; } }
or use Data::Dumper to visualize the data structure in a more Perlish way:
use Data::Dumper; print Dumper($slist->{data}), "\n";

(Untested code.)
