## Description

AnjutaPreferences is a way to let plugins register their preferences. There are mainly two ways a plugin could register its preferences in Anjuta.

First is to not use AnjutaPreferences at all. Simply register a preferences page in AnjutaPreferencesDialog using the function `anjuta_preferences_dialog_add_page()`. The plugin should take care of loading, saving and widgets synchronization of the preferences values. This can be done using GSettings bindings for example.

Second is to use `anjuta_preferences_add_page()`, which will automatically register the preferences keys and values from a glade xml file. The glade xml file contains a preferences page of the plugin. The widget names in the page are given in a particular way (see `anjuta_preferences_add_page()`) to let it know property key details. The preference dialog will automatically setup the bindings between GSettings and the widgets.

### anjuta_preferences_register_all_properties_from_builder_xml ()

    void                anjuta_preferences_register_all_properties_from_builder_xml
                                                            (AnjutaPreferences *pr,
                                                             GtkBuilder *builder,

This will register all the properties names of the format described above without considering the UI. Useful if you have the widgets shown elsewhere but you want them to be part of preferences system.

`pr` : | a AnjutaPreferences Object
`builder` : | GtkBuilder object containing the properties widgets.
`parent` : | Parent widget in the builder object

### anjuta_preferences_register_property_from_string ()

    gboolean            anjuta_preferences_register_property_from_string
                                                            (AnjutaPreferences *pr,
                                                             GSettings *settings,

This registers only one widget. The widget could be shown elsewhere. the property_description should be of the form described before.

`pr` : | a AnjutaPreferences object
`object` : | Widget to register
`property_desc` : | Property description (see `anjuta_preferences_add_page()`)
Returns : | TRUE if sucessful.

### anjuta_preferences_register_property_raw ()

    gboolean            anjuta_preferences_register_property_raw
                                                            (AnjutaPreferences *pr,
                                                             GSettings *settings,
                                                             GtkWidget *object,
                                                             const gchar *key,
                                                             const gchar *default_value,
                                                             guint flags,
                                                             AnjutaPropertyObjectType object_type,

This also registers only one widget, but instead of supplying the property parameters as a single parsable string (as done in anjuta_preferences_register_property_from_string), it takes them separately.

`pr` : | a AnjutaPreferences object
`settings` : | the GSettings object associated with that property
`object` : | Widget to register
`key` : | Property key
`default_value` : | Default value of the key
`flags` : | Flags
`object_type` : | Object type of widget
`data_type` : | Data type of the property
Returns : | TRUE if sucessful.

### anjuta_preferences_remove_page ()

    void                anjuta_preferences_remove_page      (AnjutaPreferences *pr,
                                                             const gchar *page_name);

### anjuta_property_get_widget ()

    GtkWidget *         anjuta_property_get_widget          (AnjutaProperty *prop);

Gets the widget associated with the property.

`prop` : | an AnjutaProperty reference
Returns : | a GtkWidget object associated with the property.
