=head1 NAME

Gtk2::Net::LDAP::Widgets::LdapTreeSelector - LDAP entry tree selection window

=head1 SYNOPSIS

    use Gtk2::Net::LDAP::Widgets;

    my $entryPopup = Gtk2::Net::LDAP::Widgets::LdapTreeSelector->new ($parent_window,
      $ldap_source,
      'o=People,dc=example,dc=com',
      '(|(objectClass=inetorgperson)(objectClass=organization))',
      'interactive_filter_type' => 'none',
      'single_selection' => 1
    );
    # expand entries below top-level tree entry:
    $entryPopup->{ldapTreeView}->expand_row(Gtk2::TreePath->new_from_string('0'), 0);
    $entryPopup->signal_connect (response => sub {
      my ($popup, $response) = @_;
      if($response =~ 'accept') {
        print "Selected entry DN: ".$entryPopup->get_dn;
      }
      $_[0]->destroy;
    });
    $entryPopup->show_all;

=head1 ABSTRACT

Gtk2::Net::LDAP::Widgets::LdapTreeSelector is a child class to L<Gtk2::Dialog> 
and is used to create a Gtk2 dialog which lets the user select LDAP entry/entries
displayed in a tree-like structure.

The dialog may be equipped with a search/filter box, although there might be 
problems with displaying search results when an interactive filter is set since 
there may be problems building the tree if all ancestors for an entry aren't 
included in the search result.

So it's advised to use this component without displaying a search/filter box 
('interactive_filter_type' => 'none').
