=head1 METHODS
=over 4
=item show
Generates and returns html representing the multi select box.
=cut
sub show {
my $this=shift;
$_=$this->question->extended_description;
s/\n/\n<br>\n/g;
$_.="\n<p>\n";
my %value = map { $_ => 1 } $this->translate_default;
my $id=$this->id;
$_.="<b>".$this->question->description."</b>\n<select multiple name=\"$id\">\n";
my $c=0;
foreach my $x ($this->question->choices_split) {
if (! $value{$x}) {
$_.="<option value=".$c++.">$x\n";
}
else {
$_.="<option value=".$c++." selected>$x\n";
}
}
$_.="</select>\n";
return $_;
}
=item value
When setting a value, this expects to be passed all the values they
selected. It processes these into the form used internally.
=cut
sub value {
my $this=shift;
return $this->SUPER::value() unless @_;
# This forces the function that provides values to this method
# to be called in scalar context, so we are passed a list of
# the selected values.
my @values=@_;
# Get the choices in the C locale.
$this->question->template->i18n('');
my @choices=$this->question->choices_split;
$this->question->template->i18n(1);
$this->SUPER::value(join(', ', $this->order_values(map { $choices[$_] } @values)));
}
