Hi monksp,

Here is a possible solution: First you need to direct -bg/-fg to 'SELF' otherwise these options propagate down the Descendants hierarchy of your composite overriding anything else. Then there is a problem with the Label created by Frames -labelPack option which you inherit in your Composite. I didn't dig into it further, but you can work around by creating your own Label (see below). 

use strict;
use warnings;
package LabelOption;

use Tk::widgets qw /Optionmenu/;
use base qw/Tk::Frame/;
use strict;

Construct Tk::Widget 'LabelOption';

sub ClassInit
  {
    my($class, $mw) = @_;
    $class->SUPER::ClassInit($mw);
  }

sub Populate
  {
    my($self, $args) = @_;

    $self->SUPER::Populate($args);
    my $l = $self->Label()->pack(-side => 'left');
    my $o = $self->Optionmenu->pack(-side => 'left');
    $self->Advertise('optionmenu' => $o);
    $self->ConfigSpecs(-options   => [$o],
                       -class      => [$self],
                       -background => 'SELF',
                       -foreground => 'SELF',
                       -label => [{-text=> $l}],
                       'DEFAULT'  => [$self],
                   );
    $self->Delegates('DEFAULT'    => $self);
  }

package main;

use Tk;
use Tk::Optionmenu;
my $mw  = tkinit;

my $fileloc = "Xdefaults.ocd";
$mw->optionReadfile($fileloc) if -e ($fileloc);

my(%foo) = ('bar' => [qw/yes no maybe/]);

  my $bah = $mw->LabelOption(-class   => 'Lab2',
                 -options => $foo{'bar'},
                 -label   => 'Is it safe?',
                # -labelPack => [-side => 'left'],
                )->pack();
  print  join("\n" ,map {$_->PathName} $mw->Descendants);

MainLoop;
