Ecore_Evas wrapper/helper set of functions

Ecore evas is a set of functions that make it easy to tie together ecore's main loop and input handling to evas. As such it's a natural base for EFL applications. While this combination makes it easy to create the basic aspects all applications need, for normal applications(ones with buttons, checkboxes and layouts) one should consider using Elementary.

Ecore evas is extremely well suited for applications that are not based on widgets. It has a main loop that delivers events, does basic window handling and leaves all of the drawing up to the user. This works very well if used in conjunction with Edje or if doing custom drawing as, for example, is done in games.

This is a list of examples of these functions:

Enumeration Type Documentation

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


Function Documentation

void ecore_evas_activate ( Ecore_Evas *  ee)

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

Parameters:
eeThe Ecore_Evas to activate.

This functions activates the Ecore_Evas.

Since :
3.0f(2.3.1)
Eina_Bool ecore_evas_alpha_get ( const Ecore_Evas *  ee)

Queries whether an Ecore_Evas has an alpha channel.

Parameters:
eeThe Ecore_Evas to query.
Returns:
EINA_TRUE if ee has an alpha channel, EINA_FALSE if it does not.
See also:

void ecore_evas_alpha_set ( Ecore_Evas *  ee,
Eina_Bool  alpha 
)

Sets whether an Ecore_Evas has an alpha channel or not.

Parameters:
eeThe Ecore_Evas to shape
alphaEINA_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).

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,...

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.

Ecore_Evas* ecore_evas_buffer_ecore_evas_parent_get ( Ecore_Evas *  ee)

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

Parameters:
eeAn 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.

Ecore_Evas* ecore_evas_buffer_new ( int  w,

)

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

Since (EFL) :
1.12
Parameters:
wThe width of the canvas, in pixels
hThe 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.

const void* ecore_evas_buffer_pixels_get ( Ecore_Evas *  ee)

Grabs a pointer to the actual pixels array of a given Ecore_Evas buffer canvas/window.

Parameters:
eeAn Ecore_Evas handle
Returns:
A pointer to the internal pixels array of ee

Besides returning a pointer to the actual pixel array of the given canvas, this call will force a rendering update on ee, first.

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.
