Hi, you can also try Tk::FontDialog and the RefontTree method. 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::FontDialog;

my $top=new MainWindow;

my $font;
my $fd;


my $b = $top->Button(-text => 'Choose Font',
          -command => sub {
              $font = $fd->Show;
              apply_font($font);
          })->pack;

my $f = $top->Frame->pack;
$f->Label(-text => 'Test RefontTree 1')->pack;

my $f2 = $f->Frame->pack;
$f2->Label(-text => 'Test RefontTree 2')->pack;

my $c = $f2->Canvas(-width => 100, -height => 30)->pack;
$c->createText(0,0,-anchor => 'nw', -text => 'Canvas Text');

$fd = $top->FontDialog(-nicefont => 0,
               -title => 'Select Font',
               -applycmd => \&apply_font,
               -familylabel => 'Schrift~familie',
               -fixedfontsbutton => 1,
               -nicefontsbutton => 1,
              );


my $bf = $top->Frame->pack;

$bf->Button(-text => 'OK',
        -command => sub { print "ok\n";
                  $top->destroy;})->pack(-side => 'left');

MainLoop;

sub apply_font {
    my $font = shift;
    if (defined $font) {
    $b->configure(-font => $font);
    $f->RefontTree(-font => $font, -canvas => 1);
    }
}
