* SECTION:gsettings
- * @short_description: a high-level API for application settings
+ * @short_description: High-level API for application settings
*
* The #GSettings class provides a convenient API for storing and retrieving
* application settings.
*
+ * Reads and writes can be considered to be non-blocking. Reading
+ * settings with #GSettings is typically extremely fast: on
+ * approximately the same order of magnitude (but slower than) a
+ * #GHashTable lookup. Writing settings is also extremely fast in terms
+ * of time to return to your application, but can be extremely expensive
+ * for other threads and other processes. Many settings backends
+ * (including dconf) have lazy initialisation which means in the common
+ * case of the user using their computer without modifying any settings
+ * a lot of work can be avoided. For dconf, the D-Bus service doesn't
+ * even need to be started in this case. For this reason, you should
+ * only ever modify #GSettings keys in response to explicit user action.
+ * Particular care should be paid to ensure that modifications are not
+ * made during startup -- for example, when setting the initial value
+ * of preferences widgets. The built-in g_settings_bind() functionality
+ * is careful not to write settings in response to notify signals as a
+ * result of modifications that it makes to widgets.
+ *
* When creating a GSettings instance, you have to specify a schema
* that describes the keys in your settings and their types and default
* values, as well as some other information.
* <tag class="starttag">key</tag> element.
*
* GSettings uses schemas in a compact binary form that is created
- * by the gschema-compile utility. The input is a schema description in
- * an XML format that can be described by the following DTD:
- * |[<![CDATA[
- * <!ELEMENT schemalist (schema*) >
- * <!ATTLIST schemalist gettext-domain #IMPLIED >
- *
- * <!ELEMENT schema (key|child)* >
- * <!ATTLIST schema id CDATA #REQUIRED
- * path CDATA #IMPLIED
- * gettext-domain CDATA #IMPLIED >
- *
- * <!ELEMENT key (default|summary?|description?|range?|choices?) >
- * <!-- name can only contain lowercase letters, numbers and '-' -->
- * <!-- type must be a GVariant type string -->
- * <!ATTLIST key name CDATA #REQUIRED
- * type CDATA #REQUIRED >
- *
- * <!-- the default value is specified a a serialized GVariant,
- * i.e. you have to include the quotes when specifying a string -->
- * <!ELEMENT default (#PCDATA) >
- * <!-- the presence of the l10n attribute marks a default value for
- * translation, its value is the gettext category to use -->
- * <!-- if context is present, it specifies msgctxt to use -->
- * <!ATTLIST default l10n (messages|time) #IMPLIED
- * context CDATA #IMPLIED >
- *
- * <!ELEMENT summary (#PCDATA) >
- * <!ELEMENT description (#PCDATA) >
- *
- * <!ELEMENT range (min,max) >
- * <!ELEMENT min (#PCDATA) >
- * <!ELEMENT max (#PCDATA) >
- *
- * <!ELEMENT choices (choice+) >
- * <!ELEMENT choice (alias?) >
- * <!ATTLIST choice value CDATA #REQUIRED >
- * <!ELEMENT choice (alias?) >
- * <!ELEMENT alias EMPTY >
- * <!ATTLIST alias value CDATA #REQUIRED >
- *
- * <!ELEMENT child EMPTY >
- * <!ATTLIST child name CDATA #REQUIRED
- * schema CDATA #REQUIRED >
- * ]]>
- * ]|
+ * by the <link linkend="glib-compile-schemas">glib-compile-schemas</link>
+ * utility. The input is a schema description in an XML format that can be
+ * described by the following DTD:
+ * |[<xi:include xmlns:xi="http://www.w3.org/2001/XInclude" parse="text" href="../../../../gio/gschema.dtd"><xi:fallback>FIXME: MISSING XINCLUDE CONTENT</xi:fallback></xi:include>]|
+ *
+ * glib-compile-schemas expects schema files to have the extension <filename>.gschema.xml</filename>
*
* At runtime, schemas are identified by their id (as specified
* in the <tag class="attribute">id</tag> attribute of the
* <tag class="starttag">schema</tag> element). The
* convention for schema ids is to use a dotted name, similar in
- * style to a DBus bus name, e.g. "org.gnome.font-rendering".
+ * style to a D-Bus bus name, e.g. "org.gnome.SessionManager". In particular,
+ * if the settings are for a specific service that owns a D-Bus bus name,
+ * the D-Bus bus name and schema id should match. For schemas which deal
+ * with settings not associated with one named application, the id should
+ * not use StudlyCaps, e.g. "org.gnome.font-rendering".
+ *
+ * In addition to #GVariant types, keys can have types that have enumerated
+ * types. These can be described by a <tag class="starttag">choice</tag>,
+ * <tag class="starttag">enum</tag> or <tag class="starttag">flags</tag> element, see
+ * <xref linkend="schema-enumerated"/>. The underlying type of
+ * such a key is string, but you can use g_settings_get_enum(),
+ * g_settings_set_enum(), g_settings_get_flags(), g_settings_set_flags()
+ * access the numeric values corresponding to the string value of enum
+ * and flags keys.

- * A very convenient feature of GSettings lets you bind #GObject properties
- * directly to settings, using g_settings_bind(). Once a GObject property
- * has been bound to a setting, changes on either side are automatically
- * propagated to the other side. GSettings handles details like
- * mapping between GObject and GVariant types, and preventing infinite
- * cycles.
+ * Default values are defined in the schemas that get installed by
+ * an application. Sometimes, it is necessary for a vendor or distributor
+ * to adjust these defaults. Since patching the XML source for the schema
+ * is inconvenient and error-prone,
+ * <link linkend="glib-compile-schemas">glib-compile-schemas</link> reads
+ * so-called 'vendor override' files. These are keyfiles in the same
+ * directory as the XML schema sources which can override default values.
+ * The schema id serves as the group name in the key file, and the values
+ * are expected in serialized GVariant form, as in the following example:
+ * <informalexample><programlisting>
+ * [org.gtk.Example]
+ * key1='string'
+ * key2=1.5
+ * </programlisting></informalexample>
* </para>
* <para>
- * This makes it very easy to hook up a preferences dialog to the
- * underlying settings. To make this even more convenient, GSettings
- * looks for a boolean property with the name "sensitivity" and
- * automatically binds it to the writability of the bound setting.
- * If this 'magic' gets in the way, it can be suppressed with the
- * #G_SETTINGS_BIND_NO_SENSITIVITY flag.
