Hi spx2,

If I'm following you correctly, what you want is something like this: 

#!/usr/bin/perl -w

use strict;
use warnings;
use Tk;

# User-defined
my @button_names = qw( blue red green white purple orange );


# Main program
my $mw = new MainWindow(-title => 'Button example');

my $fr = $mw->Frame()->pack(-fill => 'x');

foreach my $name (@button_names) {
    my $b = $fr->Button(-text => $name, -bg => $name)->pack(-side => '
+left');
    $b->configure(-command => sub { invoke_button($b, $name) });
}

MainLoop;

                                                                      
+ 
# Subroutines
sub invoke_button {
    my ($button, $name) = @_;
    print "You clicked on button '$name'; object is '$button'\n";
}

The trick is that you create the button first, and then configure it to use a callback which is passed a reference to the button itself.

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
