Hi,

I want to show a ProgressBar while a file is parsed. I've tried this code:
#!/usr/bin/perl

use strict;
use warnings;
use Tk;
use Tk::ProgressBar;

my $mw = tkinit;
my $btn = $mw->Button(-text => 'start...', -command => \&readdr)->pack
+();

MainLoop;

sub readdr{
  my $top = $mw->Toplevel();
  my $progress = $top->ProgressBar(
       -from => 0, 
       -to => 100, 
       -colors => [0,'green'],
       -gap => 1)->pack();
  $progress->update();

  my $file = '/path/to/file.ext';

  my $id = $progress->repeat(2,sub{
    my $values = $progress->value();
    $progress->value($values+2);
    $progress->update();
  });
 
  my $result = MyParser->new($file);
  $id->cancel();
}

But this doesn't work. The toplevel is shown, but the repeat-function is never executed.
What can I do?

My system:
* WinXP Home
* Tk 804.027
* ActivePerl 5.8.6
