34 * SECTION:gsettingsschema
35 * @short_description: Introspecting and controlling the loading of
38 * The #GSettingsSchemaSource and #GSettingsSchema APIs provide a
39 * mechanism for advanced control over the loading of schemas and a
40 * mechanism for introspecting their content.
42 * Plugin loading systems that wish to provide plugins a way to access
43 * settings face the problem of how to make the schemas for these
44 * settings visible to GSettings. Typically, a plugin will want to ship
45 * the schema along with itself and it won't be installed into the
46 * standard system directories for schemas.
48 * #GSettingsSchemaSource provides a mechanism for dealing with this by
49 * allowing the creation of a new 'schema source' from which schemas can
50 * be acquired. This schema source can then become part of the metadata
51 * associated with the plugin and queried whenever the plugin requires
52 * access to some settings.
54 * Consider the following example:
60 * GSettingsSchemaSource *schema_source;
65 * initialise_plugin (const gchar *dir)
71 * plugin->schema_source =
72 * g_settings_new_schema_source_from_directory (dir,
73 * g_settings_schema_source_get_default (), FALSE, NULL);
83 * plugin_get_settings (Plugin *plugin,
84 * const gchar *schema_id)
86 * GSettingsSchema *schema;
88 * if (schema_id == NULL)
89 * schema_id = plugin->identifier;
91 * schema = g_settings_schema_source_lookup (plugin->schema_source,
96 * ... disable the plugin or abort, etc ...
99 * return g_settings_new_full (schema, NULL, NULL);
103 * The code above shows how hooks should be added to the code that
104 * initialises (or enables) the plugin to create the schema source and
105 * how an API can be added to the plugin system to provide a convenient
106 * way for the plugin to access its settings, using the schemas that it
109 * From the standpoint of the plugin, it would need to ensure that it
110 * ships a gschemas.compiled file as part of itself, and then simply do
115 * GSettings *settings;
118 * settings = plugin_get_settings (self, NULL);
119 * some_value = g_settings_get_int (settings, "some-value");
124 * It's also possible that the plugin system expects the schema source
125 * files (ie: .gschema.xml files) instead of a gschemas.compiled file.
126 * In that case, the plugin loading system must compile the schemas for
127 * itself before attempting to create the settings source.
135 * This is an opaque structure type. You may not access it directly.

252 * This function is not required for normal uses of #GSettings but it
253 * may be useful to authors of plugin management systems.
255 * The directory should contain a file called
256 * <filename>gschemas.compiled</filename> as produced by
257 * <command>glib-compile-schemas</command>.
259 * If @trusted is %TRUE then <filename>gschemas.compiled</filename> is
260 * trusted not to be corrupted. This assumption has a performance
261 * advantage, but can result in crashes or inconsistent behaviour in the
262 * case of a corrupted file. Generally, you should set @trusted to
263 * %TRUE for files installed by the system and to %FALSE for files in
264 * the home directory.
266 * If @parent is non-%NULL then there are two effects.
268 * First, if g_settings_schema_source_lookup() is called with the
269 * @recursive flag set to %TRUE and the schema can not be found in the
270 * source, the lookup will recurse to the parent.
272 * Second, any references to other schemas specified within this
273 * source (ie: <literal>child</literal> or <literal>extends</literal>)
274 * references may be resolved from the @parent.
276 * For this second reason, except in very unusual situations, the
277 * @parent should probably be given as the default schema source, as
278 * returned by g_settings_schema_source_get_default().
