* SECTION:clutter-settings
|
||||
* @Title: ClutterSettings
|
||||
* @Short_Description: Settings configuration
|
||||
*
|
||||
* 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
