47 Perl bindings to the 2.2 series of the GConf configuration engine
48 libraries, for use with gtk2-perl.
49
51 This module allows you to use the GConf configuration system in order
52 to store/retrieve the configuration of an application. The GConf
53 system is a powerful configuration manager based on a user daemon that
54 handles a set of key and value pairs, and notifies any changes of the
55 value to every program that monitors those keys. GConf is used by
56 GNOME 2.x.

64 Some opaque data types in GConf are not registered inside the Glib type
65 system. Thus, they have been implemented in a more perlish way, when
66 possible, for the sake of coherency and following the principle of
67 least surprise for the perl developer. These changes try to preserve
68 semantics, to add syntactic sugar and to remove the need for accessor
69 methods.
70 GConfEntry
72 See Gnome2::GConf::Entry
73 GConfValue
75 See Gnome2::GConf::Value
76 GConfChangeSet
78 See Gnome2::GConf::ChangeSet
79 GConfSchema
81 See Gnome2::GConf::Schema

84 Reflecting the changes operated for the data types, some methods that
85 use those type have had the call signature modified.
86 GConfNotifyFunc
88 In C, the function passed to "Gnome2::GConf::notify_add" must have
89 the following signature:
90 void (GConfNotifyFunc *) (GConfClient * client,
92 guint cnxn_id,
93 GConfEntry * entry);
94 Where "GConfEntry" is a container for the key/value pair. Since in
96 perl there's no "GConfEntry" (see above), the "entry" parameter is
97 an hashref.
98 GConfClient::get
100 GConfClient::set
101 In C, these accessor methods return/use a "GConfValue". In perl,
102 they return/use an hashref. See Gnome2::GConf::Value
103 GConfClient::get_list
105 GConfClient::set_list
106 These accessor methods use a string for setting the type of the
107 lists (lists may have values of only one type), and an arrayref
108 containing the values.
109 GConfClient::get_pair
111 GConfClient::set_pair
112 These accessor methods use two hashref (representing "GConfValue"s)
113 for the "car" and the "cdr" parameters.
114 GConfClient::get_schema
116 GConfClient::set_schema
117 Similarly to the get/set pair above, these two methods return/use
118 an hashref. See Gnome2::GConf::Schema.
119 GConfClient::commit_change_set
121 In C, this method return a boolean value (TRUE on success, FALSE on
122 failure). On user request (using the boolean parameter
123 "remove_committed"), it also returns the "GConfChangeSet", pruned
124 of the successfully committed keys. In perl, this method returns a
125 boolean value both in scalar context or if the user sets to FALSE
126 the "remove_committed" parameter; in array context or if the user
127 requests the uncommitted keys, returns both the return value and
128 the pruned "GConfChangeSet".
