Description
Clutter depends on some settings to perform operations like detecting multiple button press events, or font options to render text.
Usually, Clutter will strive to use the platform's settings in order to be as much integrated as possible. It is, however, possible to change these settings on a per-application basis, by using the ClutterSettings singleton object and setting its properties. It is also possible, for toolkit developers, to retrieve the settings from the ClutterSettings properties when implementing new UI elements, for instance the default font name.
ClutterSettings is available since Clutter 1.4
Functions
clutter_settings_get_default ()
ClutterSettings *
clutter_settings_get_default (void);
Retrieves the singleton instance of ClutterSettings
Returns
the instance of ClutterSettings. The returned object is owned by Clutter and it should not be unreferenced directly.
[transfer none]
Since: 1.4
Types and Values
ClutterSettings
typedef struct _ClutterSettings ClutterSettings;
ClutterSettings is an opaque structure whose
members cannot be directly accessed.
