| /** |
| * SECTION:gsettings |
| * @short_description: a high-level API for application settings |
| * |
| * The #GSettings class provides a convenient API for storing and retrieving |
| * application settings. |
| * |
| * 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. |
| * |
| * Normally, a schema has as fixed path that determines where the settings |
| * are stored in the conceptual global tree of settings. However, schemas |
| * can also be 'relocatable', i.e. not equipped with a fixed path. This is |
| * useful e.g. when the schema describes an 'account', and you want to be |
| * able to store a arbitrary number of accounts. |
| * |
| * Unlike other configuration systems (like GConf), GSettings does not |
| * restrict keys to basic types like strings and numbers. GSettings stores |
| * values as #GVariant, and allows any #GVariantType for keys. Key names |
| * are restricted to lowercase characters, numbers and '-'. Furthermore, |
| * the names must begin with a lowercase character, must not end |
| * with a '-', and must not contain consecutive dashes. Key names can |
| * be up to 32 characters long. |
| * |
| * Similar to GConf, the default values in GSettings schemas can be |
| * localized, but the localized values are stored in gettext catalogs |
| * and looked up with the domain that is specified in the gettext-domain |
| * attribute of the <tag>schemalist</tag> or <tag>schema</tag> elements |
| * and the category that is specified in the l10n attribute of the |
| * <tag>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)* > |

| * 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) > |

| * <title>Binding</title> |
| * <para> |
| * 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. |
| * </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. |
| * </para> |
