Best regards,
perl -le "s==*F=e=>y~\*martinF~stronat~=>s~[^\w]~~g=>chop,print"

Nice one.

Want a brute-force way to do this? It may be ugly, but it will set the font of any grandchildren of the window to a font you specify.

Please don't use this as is and instead refine it to minimally suit your needs. I just want to give you some ideas. Uncomment the print statements to see the widgets you are operating on.

#! /usr/local/bin/perl -w

use strict;
use Tk;
use Tk::BrowseEntry;

# Create the main window
my $w;
$w->{main} = MainWindow->new;

# Create the browse entry
$w->{be} = $w->{main}->BrowseEntry( -label => "be" )->pack;
$w->{be}->insert("end", "opt1");
$w->{be}->insert("end", "opt2");
$w->{be}->insert("end", "opt3");

# Make a font
my $font = $w->{main}->fontCreate('myfont', -family => 'Helvetica', -s
+ize => 20);

# Assign it to the widget
$w->{be}->configure(-font=> 'myfont');

# Find all the children of the browse entry.
foreach ($w->{be}->children)
{
    #print "$_\n";
    # find all the grandchildren and assign them a new font.     
    foreach ($_->children)
    {
        #print "\t$_\n";
        if ($_->cget('-font'))
        {
            $_->configure(-font => 'myfont');
        }
    }
}

Many thanks - This code will also come in useful for loads of other stuff too.
