Re: perl/tk changing button commands

[kelan]

How about just having an array that holds whatever pieces of text you want and looping through it. (Untested)

#!/usr/bin/perl

use strict;
use warnings;
use Tk;

my $main = MainWindow->new;

my $label1 = $main->Text(
  -width => 50
)->pack;

my $count = 0;
my @texts = (
  "This is the first piece.\n",
  "This is the second.\n",
  "This is the third.\n",
  "etc...\n",
);

my $button = $main->Button(
  -text => "Next",
  -command => sub {
    $label1->insert('1.0', $texts[$count++]);
  }
)->pack;

MainLoop;
