Good Day, I am trying to get the selections from multiple independant Tk listboxes (thus, none of the multi-column listbox extensions, Tk::HList, Tk::Columns, Tk::MListbox, or Tk::TiedListbox, are appropriate). The problem is that Tk::Listbox seems to only be capable of remembering the selections of a single listbox at a time.

If I run the following code, select items from each list, and then press "Selections", only the selections from the most recently used list are printed.

#!/usr/bin/perl
use strict;
use warnings;
use Tk;

my $mw = MainWindow->new;
$mw->geometry(q/+100+100/);
$mw->title("Test Script");

my $lb0 = $mw->Listbox(-selectmode => 'extended')->pack;
$lb0->insert( 'end', qw/foo bar baz/ );

my $lb1 = $mw->Listbox(-selectmode => 'extended')->pack;
$lb1->insert( 'end', 1..20 );

print "$lb0 : $lb1\n";

$mw->Button( -text => "Selections", -command =>
             sub{ print
                    "1: ", join(" ", $lb0->curselection), $/,
                    "2: ", join(" ", $lb1->curselection), $/,
                } )->pack( -side => 'left' );
$mw->Button( -text => "Done", -command => \&exit )->pack;

MainLoop;

I'm not sure where the problem is.

Thanks,
