I am trying to throw something together quickly, but ran into this problem. Code is like this at this moment:

use Net::Telnet;
use Tk;
use Data::Dumper;
use XML::Simple;

use strict;
use warnings;

my $tasks = XMLin("command.xml");
print Dumper($tasks);

my $mw = MainWindow->new();
for (0..$#{@{$tasks->{"task"}}}) {
        $mw->Button(text => $tasks->{"task"}->[$_]->{"description"}, c
+ommand => sub {pub($_)})->pack();
}
MainLoop;

sub pub {
        my $task_id = shift;
        print "task id = $task_id\n";
        my $t = new Net::Telnet(timeout => 10, Prompt => '[AATS1]$');
        $t->open("ofgaix2");
        $t->login("rpts1", "aats1");
        my @lines;
        my $cmds = $tasks->{"task"}->[$task_id]->{"command"};
        for (0..$#{@{$cmds}}) {
                @lines = $t->cmd($cmds->[$_]->{"string"});
                print @lines;
        }
}

The problem is that $task_id is not properly passed into the sub. All what I need is a way to identify who triggered the sub.

Thanks in advance.

By the way, there might be multiple ways to resolve it, at the same time, I am still interested in whether Tk itself provides a way to find out who trigger the action.
