Methods / Constructors
Method / Constructor		Defined By
	new Clutter.Backend () Create a new Clutter.Backend Create a new Clutter.Backend
	get_double_click_distance () : guint32 Retrieves the distance used to verify a double click event Retrieves the distance used to verify a double click event Returns: guint32 a distance, in pixels.	Clutter.Backend
	get_double_click_time () : guint32 Gets the maximum time between two button press events, as set by clutter_backend_set_double_click_time(). Gets the maximum time between two button press events, as set by clutter_backend_set_double_click_time(). Returns: guint32 a time in milliseconds	Clutter.Backend
	get_font_name () : String Retrieves the default font name as set by clutter_backend_set_font_name(). Retrieves the default font name as set by clutter_backend_set_font_name(). owned by the ClutterBackend and should never be modified or freed Returns: String the font name for the backend. The returned string is	Clutter.Backend
	get_font_options () : cairo.FontOptions Retrieves the font options for backend. Retrieves the font options for backend. The returned cairo_font_options_t is owned by the backend and should not be modified or freed Returns: cairo.FontOptions the font options of the ClutterBackend.	Clutter.Backend
	get_resolution () : gdouble Gets the resolution for font handling on the screen. Gets the resolution for font handling on the screen. The resolution is a scale factor between points specified in a PangoFontDescription and cairo units. The default value is 96.0, meaning that a 10 point font will be 13 units high (10 * 96. / 72. = 13.3). Clutter will set the resolution using the current backend when initializing; the resolution is also stored in the ClutterSettings:font-dpi property. has been set. Returns: gdouble the current resolution, or -1 if no resolution	Clutter.Backend
	set_double_click_distance (guint32 *distance) : none Sets the maximum distance used to verify a double click event. Sets the maximum distance used to verify a double click event. Parameters: guint32 distance* Required (not null) a distance, in pixels Returns: none	Clutter.Backend
	set_double_click_time (guint32 *msec) : none Sets the maximum time between two button press events, used to verify whether it's a double click event or not. Sets the maximum time between two button press events, used to verify whether it's a double click event or not. Parameters: guint32 msec* Required (not null) milliseconds between two button press events Returns: none	Clutter.Backend
	set_font_name (String *font_name) : none Sets the default font to be used by Clutter. Sets the default font to be used by Clutter. The font_name* string must either be NULL, which means that the font name from the default ClutterBackend will be used; or be something that can be parsed by the pango_font_description_from_string() function. Parameters: String font_name Required (not null) the name of the font Returns: none	Clutter.Backend
	set_font_options (FontOptions *options) : none Sets the new font options for backend. Sets the new font options for backend. The ClutterBackend* will copy the cairo_font_options_t. If options is NULL, the first following call to clutter_backend_get_font_options() will return the default font options for backend. This function is intended for actors creating a Pango layout using the PangoCairo API. Parameters: cairo.FontOptions options Required (not null) Cairo font options for the backend, or NULL Returns: none	Clutter.Backend
	set_resolution (gdouble *dpi) : none Sets the resolution for font handling on the screen. Sets the resolution for font handling on the screen. This is a scale factor between points specified in a PangoFontDescription* and cairo units. The default value is 96, meaning that a 10 point font will be 13 units high. (10 * 96. / 72. = 13.3). Applications should never need to call this function. Parameters: gdouble dpi Required (not null) the resolution in "dots per inch" (Physical inches aren't actually involved; the terminology is conventional). Returns: none	Clutter.Backend
