This option causes updates of the Ecore_Evas to be done on a pixmap, and then copied to the window, or the pixmap used directly on the window, depending on the setting.

Enumerator:

ECORE_EVAS_AVOID_DAMAGE_NONE	every expose event triggers a new damage and consequently render of the affected area. The rendering of things happens directly on the window
ECORE_EVAS_AVOID_DAMAGE_EXPOSE	there's a pixmap where everything is rendered into, and then copied to the window. On expose events, there's no need to render things again, just to copy the exposed region to the window
ECORE_EVAS_AVOID_DAMAGE_BUILT_IN	there's the same pixmap as the previous one, but it is set as a "background pixmap" of the window. The rendered things appear directly on the window, with no need to copy anything, but would stay stored on the pixmap, so there's no need to render things again on expose events. This option can be faster than the previous one, but may lead to artifacts during resize of the window

Activates (set focus to, via the window manager) an Ecore_Evas' window.

Parameters:

ee	The Ecore_Evas to activate.

This functions activates the Ecore_Evas.

Since :

3.0

Queries whether an Ecore_Evas has an alpha channel.

Parameters:

ee	The Ecore_Evas to query.

Returns:

EINA_TRUE if ee has an alpha channel, EINA_FALSE if it does not.

See also:

ecore_evas_alpha_set()

Since :

3.0

Sets whether an Ecore_Evas has an alpha channel or not.

Parameters:

ee	The Ecore_Evas to shape
alpha	EINA_TRUE to enable the alpha channel, EINA_FALSE to disable it

This function allows you to make an Ecore_Evas translucent using an alpha channel. See ecore_evas_shaped_set() for details. The difference between a shaped window and a window with an alpha channel is that an alpha channel supports multiple levels of transparency, as opposed to the 1 bit transparency of a shaped window (a pixel is either opaque, or it's transparent).

Warning:

Support for this depends on the underlying windowing system.

Parameters:

ee	The Ecore_Evas

Returns:

List of allowed auxiliary hint IDs.

Note:

Warning:

Support for this depends on the underlying windowing system.

Since (EFL) :

1.10.0

Since :

3.0

Gets the list of supported auxiliary hint strings.

Parameters:

ee	The Ecore_Evas

Returns:

List of supported auxiliary hint strings.

Note:

Do not change the returned list of its contents. Auxiliary hint strings are internal and should be considered constants, do not free or modify them.

Warning:

Support for this depends on the underlying windowing system.

The window auxiliary hint is the value which is used to decide which actions should be made available to the user by the window manager. If you want to set a specific hint on your window, then you should check whether it exists in the supported auxiliary hints that are registered in the root window by the window manager. Once you've added an auxiliary hint, you can get a new ID which is used to change value and delete hint. The window manager sends the response message to the application on receiving auxiliary hint change event. A list of auxiliary hints within the Ecore_Evas has this format: ID:HINT:VALUE,ID:HINT:VALUE,...

Creates a new Ecore_Evas canvas bound to the Evas buffer engine, giving custom allocation and freeing functions for the canvas memory region.

Parameters:

w	The width of the canvas, in canvas units
h	The height of the canvas, in canvas units
alloc_func	Function to be called to allocate the memory needed for the new buffer canvas. data will be passed the same value as the data of this function, while size will be passed w times h times sizeof(int).
free_func	Function to be called to free the memory used by the new buffer canvas. data will be passed the same value as the data of this function, while pix will be passed the canvas memory pointer.
data	Custom data to be passed to the allocation and freeing functions

Returns:

A new Ecore_Evas instance or NULL, on failure

This creates a new buffer canvas wrapper, with image data array bound to the ARGB format, 8 bits per pixel.

This function is useful when one wants an Ecore_Evas buffer canvas with a custom allocation function, like one getting memory chunks from a memory pool, for example.

On any resizing of this Ecore_Evas buffer canvas, its image data will be freed, to be allocated again with the new size.

Note:

w and h sizes have to greater or equal to 1. Otherwise, they'll be interpreted as 1, exactly.

See also:

ecore_evas_buffer_new()

Since :

3.0

Returns a pointer to the Ecore_Evas parent of the given Ecore_Evas.

Parameters:

ee	An Ecore_Evas handle

Returns:

A pointer to the Ecore_Evas parent.

A use case for the function is to determine if the buffer is used inside X11 or Wayland. Since the buffer engine doesn't give any indication on it, we need to retrieve information from the Ecore_Evas parent.

Since (EFL) :

1.13

Since :

3.0

Creates a new Ecore_Evas canvas bound to the Evas buffer engine.

Since (EFL) :

1.12

Parameters:

w	The width of the canvas, in pixels
h	The height of the canvas, in pixels

Returns:

A new Ecore_Evas instance or NULL, on failure

This creates a new buffer canvas wrapper, with image data array bound to the ARGB format, 8 bits per pixel.

This function will allocate the needed pixels array with canonical malloc(). If you wish a custom function to allocate it, consider using ecore_evas_buffer_allocfunc_new(), instead.

Note:

This function actually is a wrapper on ecore_evas_buffer_allocfunc_new(), using the same w and h arguments and canonical malloc() and free() to the memory allocation and freeing functions. See that function's documentation for more details.

Since :

3.0

Examples:

Parameters:

Returns:

A pointer to the internal pixels array of ee

A common use case for this call is to create an image object, from another canvas, to have as data ee's contents, thus snapshoting the canvas. For that case, one can also use the ecore_evas_object_image_new() helper function.
