22 * SECTION:anjuta-preferences
23 * @short_description: Anjuta Prefereces system.
24 * @see_also: #AnjutaPreferencesDialog
25 * @stability: Unstable
26 * @include: libanjuta/anjuta-preferences.h
27 *
28 * #AnjutaPreferences is a way to let plugins register their preferences. There
29 * are mainly two ways a plugin could register its preferences in Anjuta.
30 *
31 * First is to not use #AnjutaPreferences at all. Simply register a
32 * preferences page in #AnjutaPreferencesDialog using the function
33 * anjuta_preferences_dialog_add_page(). The plugin should take
34 * care of loading, saving and widgets synchronization of the
35 * preferences values. It is particularly useful if the plugin
36 * uses gconf system for its preferences. Also no "changed"
37 * signal will be emitted from it.
38 *
39 * Second is to use anjuta_preferences_add_page(), which will
40 * automatically register the preferences keys and values from
41 * a glade xml file. The glade xml file contains a preferences
42 * page of the plugin. The widget names in the page are
43 * given in a particular way (see anjuta_preferences_add_page()) to
44 * let it know property key details. Loading, saving and
45 * widget synchronization are automatically done. "changed" signal is
46 * emitted when a preference is changed.
47 *
48 * anjuta_preferences_register_all_properties_from_glade_xml() only registers
49 * the preferences propery keys for automatic loading, saving and widget
50 * syncrhronization, but does not add the page in preferences dialog. It
51 * is useful if the plugin wants to show the preferences page somewhere else.
52 *
53 * anjuta_preferences_register_property_from_string() is similar to
54 * anjuta_preferences_register_all_properties_from_glade_xml(), but it only
55 * registers one property, the detail of which is given in its arguments.
56 * anjuta_preferences_register_property_custom() is used to register a
57 * property that uses a widget which is not supported by #AnjutaPreferences.
