=head1 NAME
Gtk2::Ex::FormFactory::Combo - A Combo in a FormFactory framework
=head1 SYNOPSIS
  Gtk2::Ex::FormFactory::Combo->new (
    ...
    Gtk2::Ex::FormFactory::Widget attributes
  );
=head1 DESCRIPTION
This class implements a text entry with a popdown list of presets
in a Gtk2::Ex::FormFactory framework. The content of the entry
is the value of the associated application object attribute.
=head1 OBJECT HIERARCHY
  Gtk2::Ex::FormFactory::Intro
  Gtk2::Ex::FormFactory::Widget
  +--- Gtk2::Ex::FormFactory::Combo
  Gtk2::Ex::FormFactory::Layout
  Gtk2::Ex::FormFactory::Rules
  Gtk2::Ex::FormFactory::Context
  Gtk2::Ex::FormFactory::Proxy
=head1 ATTRIBUTES
This module has no additional attributes over those derived
from Gtk2::Ex::FormFactory::Widget.
=head1 REQUIREMENTS FOR ASSOCIATED APPLICATION OBJECTS
Application objects represented by a Gtk2::Ex::FormFactory::Combo
must define additional methods. The naming of the methods listed
beyond uses the standard B<get_> prefix for the attribute read
accessor. B<ATTR> needs to be replaced by the actual name of
the attribute associated with the widget.
=over 4
=item B<get_ATTR_presets>
