These are functions setting and querying which rendering engine Elementary will use for drawing its windows' pixels.

The following are the available engines:

"fb" (Framebuffer)
"buffer" (Pixel Memory Buffer)
"ews" (Ecore + Evas Single Process Windowing System)
NULL - no engine config

const char* elm_config_accel_preference_get ( void )

Get Elementary's preferred engine to use.

Returns:: The acceleration preference hint string

Note:: there's no need to free the returned string, here.

See elm_config_accel_preference_set() for more information, but this simply returns what was set by this call, nothing more.

See also:: elm_config_accel_preference_set()

Since (EFL) :: 1.10

Since :: 2.3.1

Eina_Bool elm_config_accel_preference_override_get ( void )

Get the acceleration override preference flag

This gets the acceleration override preference. This is a flag that has the global system acceleration preference configuration forcibly override whatever acceleration preference the application may want.

Returns:: If acceleration override is enabled

Since (EFL) :: 1.11

Since :: 2.3.1

void elm_config_accel_preference_override_set ( Eina_Bool enabled )

Set the acceleration override preference flag

This sets the acceleration override preference. This is a flag that has the global system acceleration preference configuration forcibly override whatever acceleration preference the application may want.

Parameters:

enabled This should be EINA_TRUE if enabled, or EINA_FALSE if not.

See also:: elm_config_accel_preference_set()

Since (EFL) :: 1.11

Since :: 2.3.1

void elm_config_accel_preference_set ( const char * pref )

Set Elementary's acceleration preferences for new windows.

Parameters:

pref	The preference desired as a normal C string

Note that it will take effect only to Elementary windows created after this is called. The pref string is a freeform C string that indicates what kind of acceleration is preferred. Here "acceleration" majorly means to rendering and which hardware unit application renders GUIs with. This may or may not be honored, but a best attempt will be made. Known strings are as follows:

"gl", "opengl" - try use OpenGL. "3d" - try and use a 3d acceleration unit. "hw", "hardware", "accel" - try any acceleration unit (best possible) "none" - use no acceleration. try use software (since 1.16)

Since 1.14, it is also possible to specify some GL properties for the GL window surface. This allows applications to use GLView with depth, stencil and MSAA buffers with direct rendering. The new accel preference string format is thus "{HW Accel}[:depth{value}[:stencil{value}[:msaa{str}]]]".

Accepted values for depth are for instance "depth", "depth16", "depth24". Accepted values for stencil are "stencil", "stencil1", "stencil8". For MSAA, only predefined strings are accepted: "msaa", "msaa_low", "msaa_mid" and "msaa_high". The selected configuration is not guaranteed and is only valid in case of GL acceleration. Only the base acceleration string will be saved (e.g. "gl" or "hw").

Full examples include:

"gl", - try to use OpenGL "hw:depth:stencil", - use HW acceleration with default depth and stencil buffers "opengl:depth24:stencil8:msaa_mid" - use OpenGL with 24-bit depth, 8-bit stencil and a medium number of MSAA samples in the backbuffer.

This takes precedence over engine preferences set with elm_config_preferred_engine_set().

void elm_config_color_overlay_apply ( void )

Get Elementary's list of color overlays, set with elm_config_color_overlay_set().

Returns:: The color overlays list, with Elm_Color_Overlay blobs as data.

Since (EFL) :: 1.10

For each color class, one can set a color overlay for it, overriding the default color properties for that class coming from the theme in use. There is no need to free this list.

See also:: elm_config_color_overlay_set(); elm_config_color_overlay_unset().

Since :: 2.3.1

void elm_config_color_overlay_set	(	const char *	color_class,
		int	r,
		int	g,
		int	b,
		int	a,
		int	r2,
		int	g2,
		int	b2,
		int	a2,
		int	r3,
		int	g3,
		int	b3,
		int	a3
	)

Set a color overlay for a given Elementary color class.

Parameters:

color_class	Color class name
r	Object Red value
g	Object Green value
b	Object Blue value
a	Object Alpha value
r2	Text outline Red value
g2	Text outline Green value
b2	Text outline Blue value
a2	Text outline Alpha value
r3	Text shadow Red value
g3	Text shadow Green value
b3	Text shadow Blue value
a3	Text shadow Alpha value

Since (EFL) :: 1.10

The first color is for the object itself, the second color is for the text outline, and the third color is for the text shadow.

Note:: The second two color are only for texts.

Setting color emits a signal "color_class,set" with source being the given color class in all edje objects.

See also:: elm_config_color_overlay_list_get(); elm_config_color_overlay_unset(); edje_color_class_set()

Note:: unlike Evas, Edje colors are not pre-multiplied. That is, half-transparent white is 255 255 255 128.

Since :: 2.3.1

void elm_config_color_overlay_unset ( const char * color_class )

const char* elm_config_preferred_engine_get ( void )

Get Elementary's preferred engine to use.

Returns:: The rendering engine's name

Note:: there's no need to free the returned string, here.

This gets the global rendering engine that is applied to all Elementary applications and is PREFERRED by the application. This can (and will) override the engine configured for all applications which. It is rare to explicitly ask for an engine (likely need is the buffer engine and not much more), so use elm_config_accel_preference_get() and elm_config_accel_preference_set() normally.

See also:: elm_config_preferred_engine_set()

Since :: 2.3.1

void elm_config_preferred_engine_set ( const char * engine )

Parameters:

engine The rendering engine's name

Note that it will take effect only to Elementary windows created after this is called. This overrides the engine set by configuration at application startup. Note that it is a hint and may not be honored. It is rare to explicitly ask for an engine (likely need is the buffer engine and not much more), so use elm_config_accel_preference_get() and elm_config_accel_preference_set() normally.
