NAME

Gnome2::GConf - (DEPRECATED) Perl wrappers for the GConf configuration engine.

SYNOPSIS

  use Gnome2::GConf;

  my $client = Gnome2::GConf::Client->get_default;
  my $app_key = "/apps/myapp/mykey";
  
  $client->add_dir($app_key, 'preload-none');
  
  # add a notify for the key
  my $notify_id = $client->notify_add($app_key, sub {
      my ($client, $cnxn_id, $entry) = @_;
      return unless $entry->{value};
                
      if ($entry->{value}->{type} eq 'string') {
        printf "key '%s' changed to '%s'\n",
               $entry->{key},
               $entry->{value}->{value};
      }
    });
  
  my $string = $client->get_string($app_key);
  $string = 'some string' unless $string;
  
  $client->set($app_key, { type => 'string', data => $string });
  
  # set a schema for the key
  $client->set_schema ($app_key,
      {
        type => 'string',
        locale => 'C',
        short_desc => 'Some key.',
        long_desc => 'This key does something.',
        owner => 'some_program'
      });
  
  # remove the notification callback
  $client->notify_remove($notify_id);

ABSTRACT

(DEPRECATED) Perl bindings to the 2.2 series of the GConf configuration engine libraries, for use with gtk2-perl.

DESCRIPTION

NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE

This module has been deprecated by the Gtk-Perl project. This means that the module will no longer be updated with security patches, bug fixes, or when changes are made in the Perl ABI. The Git repo for this module has been archived (made read-only), it will no longer possible to submit new commits to it. You are more than welcome to ask about this module on the Gtk-Perl mailing list, but our priorities going forward will be maintaining Gtk-Perl modules that are supported and maintained upstream; this module is neither.

Since this module is licensed under the LGPL v2, you may also fork this module, if you wish, but you will need to use a different name for it on CPAN, and the Gtk-Perl team requests that you use your own resources (mailing list, Git repos, bug trackers, etc.) to maintain your fork going forward.

This module allows you to use the GConf configuration system in order to store/retrieve the configuration of an application. The GConf system is a powerful configuration manager based on a user daemon that handles a set of key and value pairs, and notifies any changes of the value to every program that monitors those keys. GConf is used by GNOME 2.x.

DIFFERENT DATA TYPES

Some opaque data types in GConf are not registered inside the Glib type system. Thus, they have been implemented in a more perlish way, when possible, for the sake of coherency and following the principle of least surprise for the perl developer. These changes try to preserve semantics, to add syntactic sugar and to remove the need for accessor methods.

GConfEntry

See Gnome2::GConf::Entry

GConfValue

See Gnome2::GConf::Value

GConfChangeSet

See Gnome2::GConf::ChangeSet

GConfSchema

See Gnome2::GConf::Schema

DIFFERENT CALL SIGNATURES

Reflecting the changes operated for the data types, some methods that use those type have had the call signature modified.

GConfNotifyFunc

In C, the function passed to Gnome2::GConf::notify_add must have the following signature:

        void (GConfNotifyFunc *) (GConfClient * client,
                                  guint cnxn_id,
                                  GConfEntry * entry);

Where GConfEntry is a container for the key/value pair. Since in perl there's no GConfEntry (see above), the entry parameter is an hashref.

GConfClient::get

GConfClient::set

In C, these accessor methods return/use a GConfValue. In perl, they return/use an hashref. See Gnome2::GConf::Value

GConfClient::get_list

GConfClient::set_list

These accessor methods use a string for setting the type of the lists (lists may have values of only one type), and an arrayref containing the values.

GConfClient::get_pair

GConfClient::set_pair

These accessor methods use two hashref (representing GConfValues) for the car and the cdr parameters.

GConfClient::get_schema

GConfClient::set_schema

Similarly to the get/set pair above, these two methods return/use an hashref. See Gnome2::GConf::Schema.

GConfClient::commit_change_set

In C, this method return a boolean value (TRUE on success, FALSE on failure). On user request (using the boolean parameter remove_committed), it also returns the GConfChangeSet, pruned of the successfully committed keys. In perl, this method returns a boolean value both in scalar context or if the user sets to FALSE the remove_committed parameter; in array context or if the user requests the uncommitted keys, returns both the return value and the pruned GConfChangeSet.
