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.
typedef enum { ANJUTA_PROPERTY_OBJECT_TYPE_TOGGLE, ANJUTA_PROPERTY_OBJECT_TYPE_SPIN, ANJUTA_PROPERTY_OBJECT_TYPE_ENTRY, ANJUTA_PROPERTY_OBJECT_TYPE_MENU, ANJUTA_PROPERTY_OBJECT_TYPE_TEXT, ANJUTA_PROPERTY_OBJECT_TYPE_COLOR, ANJUTA_PROPERTY_OBJECT_TYPE_FONT } AnjutaPropertyObjectType;
typedef enum { ANJUTA_PROPERTY_DATA_TYPE_BOOL, ANJUTA_PROPERTY_DATA_TYPE_INT, ANJUTA_PROPERTY_DATA_TYPE_TEXT, ANJUTA_PROPERTY_DATA_TYPE_COLOR, ANJUTA_PROPERTY_DATA_TYPE_FONT } AnjutaPropertyDataType;
typedef enum { ANJUTA_PREFERENCES_FILTER_NONE = 0, ANJUTA_PREFERENCES_FILTER_PROJECT = 1 } AnjutaPreferencesFilterType;
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. |
gboolean (*AnjutaPreferencesCallback) (AnjutaPreferences *pr, const gchar *key, gpointer data);
pr : |
|
key : |
|
data : |
|
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 gchar *glade_widget_name, const gchar *title, 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 |

void anjuta_preferences_register_all_properties_from_glade_xml (AnjutaPreferences *pr, GladeXML *gxml, GtkWidget *parent);

gboolean anjuta_preferences_register_property_from_string (AnjutaPreferences *pr, GtkWidget *object, const gchar *property_desc);
