=head1 NAME
Debconf::Element::Multiselect - Base multiselect input element
=cut
package Debconf::Element::Multiselect;
use strict;
use base qw(Debconf::Element::Select);
=head1 DESCRIPTION
This is a base Multiselect input element. It inherits from the base Select
input element.
=head1 METHODS
=item order_values
Given a set of values, reorders then to be in the same order as the choices
field of the question's template, and returns them.
=cut
sub order_values {
my $this=shift;
my %vals=map { $_ => 1 } @_;
# Make sure that the choices are in the C locale, like the values
# are.
$this->question->template->i18n('');
my @ret=grep { $vals{$_} } $this->question->choices_split;
$this->question->template->i18n(1);
return @ret;
}
=item show
Unlike select lists, multiselect questions are visible if there is just one
choice.
=cut
sub visible {
my $this=shift;
my @choices=$this->question->choices_split;
return ($#choices >= 0);
}
=item translate_default
This method returns default value(s), in the user's language, suitable for
displaying to the user. Defaults are stored internally in the C locale;
this method does any necessary translation to the current locale.
=cut
sub translate_default {
my $this=shift;
# I need both the translated and the non-translated choices.
my @choices=$this->question->choices_split;
$this->question->template->i18n('');
my @choices_c=$this->question->choices_split;
$this->question->template->i18n(1);
my @ret;
# Translate each default.
foreach my $c_default ($this->question->value_split) {
foreach (my $x=0; $x <= $#choices; $x++) {
push @ret, $choices[$x]
if $choices_c[$x] eq $c_default;
}
}
return @ret;
}
