Another example..... notice (as of the time I tested this with an older Tk), you need to predeclare the font with fontCreate. Newer Tk's seem to work. YMMV. Menus are so tricky. ;-)

#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;
use Tk;

my $mw = MainWindow->new(
    -title      => 'Testing Tk::Menu',
    -width      => 500,
    -height     => 300,
    -background => 'yellow',
    -name       => 'Demo',
);
$mw->minsize( 500, 300 );

my $bf = $mw->fontCreate('big',
   -family=>'arial',
   -weight=>'bold',
   -size=>int(-18*18/14));

my $menubar = $mw->Menu(
    -type => 'menubar',
#    -font => "Verdana 18 bold",    # HAS NO EFFECT!
     -font => $bf
);

$mw->configure( -menu      => $menubar );
#$menubar->configure( -font => "Verdana 14 bold" );    # HAS NO EFFECT
+!

my $m1 = $menubar->cascade(
    -label     => 'File',
    -tearoff   => 0,
    -menuitems => [
        [
            Button   => 'New',
#            -font    => "Verdana 16 bold",            # OK
            -font => 'big',
        -command => \&create_new_file
        ],
        [
            Button   => 'Open',
            -font => 'big',
        -command => \&open_file
        
    ],
        [
            Button   => 'Exit',
            -command => sub {exit}
        ],
    ]
);

MainLoop;

sub create_new_file { print "create_new_file...\n"; }

sub open_file { print "open_file...\n"; }
