=head1 NAME
CGI::Test::Form::Widget::Box::Radio - A radio button widget
=head1 SYNOPSIS
# Inherits from CGI::Test::Form::Widget::Box
# $form is a CGI::Test::Form
my @title = $form->radios_named("title");
my ($mister) = grep { $_->value eq "Mr" } @title;
$mister->check if defined $mister;
my $title = $form->radio_by_name("title");
$title->check_tagged("Mr");
=head1 DESCRIPTION
This class represents a radio button widget, which may be checked at
will by users. All other radio buttons of the same group are automatically
unchecked.
If no radio button is checked initially, C<CGI::Test> arbitrarily chooses
the first one listed and warns you via C<warn>.
The interface is the same as the one described
in L<CGI::Test::Form::Widget::Box>.
Any attempt to C<uncheck> a radio button will be ignored, and a warning
emitted via C<carp>, to help you identify the caller.
=head1 AUTHORS
The original author is Raphael Manfredi.
