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. It is particularly useful if the plugin
uses gconf system for its preferences. Also no "changed"
signal will be emitted from it.
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. Loading, saving and
widget synchronization are automatically done. "changed" signal is
emitted when a preference is changed.
anjuta_preferences_register_all_properties_from_glade_xml()
only registers
the preferences propery keys for automatic loading, saving and widget
syncrhronization, but does not add the page in preferences dialog. It
is useful if the plugin wants to show the preferences page somewhere else.
anjuta_preferences_register_property_from_string()
is similar to
anjuta_preferences_register_all_properties_from_glade_xml()
, but it only
registers one property, the detail of which is given in its arguments.
anjuta_preferences_register_property_custom()
is used to register a
property that uses a widget which is not supported by AnjutaPreferences.

Returns : |
GtkWidget* anjuta_preferences_new (void);
Creates a new AnjutaPreferences object
Returns : | A AnjutaPreferences object. |
void anjuta_preferences_add_page (AnjutaPreferences *pr, GladeXML *gxml, const char *glade_widget_name, const gchar *icon_filename);
Add a page to the preferences sytem. gxml is the GladeXML object of the glade dialog containing the page widget. The glade dialog will contain the layout of the preferences widgets. The widgets which are preference widgets (e.g. toggle button) should have widget names of the form:
preferences_OBJECTTYPE:DATATYPE:DEFAULT:FLAGS:PROPERTYKEY
where,
OBJECTTYPE is 'toggle', 'spin', 'entry', 'text', 'color' or 'font'.
DATATYPE is 'bool', 'int', 'float', 'text', 'color' or 'font'.
DEFAULT is the default value (in the appropriate format). The format
for color is 'XXXXXX' representing RGB value and for
font, it is the pango font description.
FLAGS is any flag associated with the property. Currently it
has only two values -- 0 and 1. For normal preference
property which is saved/retrieved globally, the flag = 0.
For preference property which is also saved/retrieved
along with the project, the flag = 1.
PROPERTYKEY is the property key. e.g - 'tab.size'.
All widgets having the above names in the gxml tree will be registered and will become part of auto saving/loading. For example, refer to anjuta preferences dialogs and study the widget names.
pr : | a AnjutaPreferences object |
gxml : | GladeXML object containing the preferences page |
glade_widget_name : | Page widget name (as give with glade interface editor). The widget will be searched with the given name and detached (that is, removed from the container, if present) from it's parent. |
icon_filename : | File name (of the form filename.png) of the icon representing the preference page. |
void anjuta_preferences_register_all_properties_from_glade_xml (AnjutaPreferences *pr, GladeXML *gxml, GtkWidget *parent);
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 |
gxml : | GladeXML object containing the properties widgets. |
parent : | Parent widget in the gxml object |
gboolean anjuta_preferences_register_property_from_string (AnjutaPreferences *pr, GtkWidget *object, const gchar *property_desc);
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_pag() )
|
Returns : | TRUE if sucessful. |
gboolean anjuta_preferences_register_property_raw (AnjutaPreferences *pr, GtkWidget *object, const gchar *key, const gchar *default_value, guint flags, AnjutaPropertyObjectType object_type, AnjutaPropertyDataType data_type);
This also registers only one widget, but instead of supplying the property parameters as a single parsable string (as done in previous method), it takes them separately.
pr : | a AnjutaPreferences object |
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. |
gboolean anjuta_preferences_register_property_custom (AnjutaPreferences *pr, GtkWidget *object, const gchar *key, const gchar *default_value, AnjutaPropertyDataType data_type, guint flags, void (*set_property) (AnjutaProperty *prop, const gchar *value), gchar* (*get_property) (AnjutaProperty *));
This is meant for complex widgets which can not be set/get with the standard object set/get methods. Custom set/get methods are passed for the property to set/get the value to/from the widget.
pr : | a AnjutaPreferences object. |
object : | Object to register. |
key : | Property key. |
default_value : | Default value of the key. |
data_type : | property data type. |
flags : | Flags |
set_property : | Set property to widget callback. |
get_property : | Get property from widget callback. |
Returns : | TRUE if sucessful. |
void anjuta_preferences_reset_defaults (AnjutaPreferences *pr);
Resets the default values into the keys
pr : | a AnjutaPreferences object. |
gboolean anjuta_preferences_save (AnjutaPreferences *pr, FILE *stream);
pr : | |
stream : | |
Returns : |
gboolean anjuta_preferences_save_filtered (AnjutaPreferences *pr, FILE *stream, AnjutaPreferencesFilterType filter);
pr : | |
stream : | |
filter : | |
Returns : |
gboolean anjuta_preferences_save_gconf (AnjutaPreferences *pr, AnjutaPreferencesFilterType filter);
pr : | |

Returns : |
gboolean anjuta_preferences_load_gconf (AnjutaPreferences *pr);
pr : | |
Returns : |
void anjuta_preferences_foreach (AnjutaPreferences *pr, AnjutaPreferencesFilterType filter, AnjutaPreferencesCallback callback, gpointer data);
Calls callback
function for each of the registered property keys. Keys
with matching filter
flags are left out of the loop. If filter
is
ANJUTA_PREFERENCES_FILTER_NONE, all properties are selected for the loop.
pr : | A AnjutaPreferences object. |
filter : | Keys to filter out from the loop. |
callback : | User callback function. |
data : | User data passed to callback
|
void anjuta_preferences_sync_to_session (AnjutaPreferences *pr);
pr : |
guint anjuta_preferences_notify_add (AnjutaPreferences *pr, const gchar *key, GConfClientNotifyFunc func, gpointer data, GFreeFunc destroy_notify);
This is similar to gconf_client_notify_add()
, except that the key is not
given as full path. Only anjuta preference key is given. The key prefix
is added internally.
pr : | A AnjutaPreferences object. |
key : | Key to monitor. |
func : | User callback function. |
data : | User data passed to func
|
destroy_notify : | Destroy notify function - called when notify is removed. |
Returns : | Notify ID. |
void anjuta_preferences_notify_remove (AnjutaPreferences *pr, guint notify_id);
Removes the notify callback added with anjuta_preferences_notify_add()
.
pr : | A AnjutaPreferences object. |
notify_id : | Notify ID returned by anjuta_preferences_notify_add() .

const gchar* anjuta_preferences_get_prefix (AnjutaPreferences *pr);
Returns the gconf key prefix used by anjuta to store its preferences.
pr : | A AnjutaPreferences object. |
Returns : | preferences keys prefix. |
