Ecore_Evas wrapper/helper set of functions
Ecore

Ecore evas is a set of functions that makes it easy to tie together ecore's main loop and input handling to evas. More...

## Modules
| Ecore_Evas Single Process Windowing System.
| These are global scope functions to manage the EWS to be used by ecore_evas_ews_new().
| External plug/socket infrastructure to remote canvases
| These functions allow 1 process to create a "socket" was pluged into which another process can create a "plug" remotely to plug into.

## Detailed Description

Ecore evas is a set of functions that makes 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:

- Ecore Evas basics example
- Ecore Evas Object example
- Ecore Evas Callbacks
- Ecore_Evas window size hints
- Ecore_Evas buffer example
- Ecore_Evas (image) buffer example

EAPI Eina_List* ecore_evas_engines_get | ( | void |  | ) |

Return a list of supported engines names.

Returns
  Newly allocated list with engines names. Engines names strings are internal and should be considered constants, do not free or modify them, to free the list use ecore_evas_engines_free().

References eina_list_clone().

Referenced by ecore_getopt_callback_ecore_evas_list_engines().

EAPI void ecore_evas_engines_free | ( | Eina_List * | engines | ) |

Free list returned by ecore_evas_engines_get()

Parameters

  engines | list with engines names

References eina_list_free().

Referenced by ecore_getopt_callback_ecore_evas_list_engines().

EAPI Ecore_Evas* ecore_evas_new | ( | const char * | engine_name,
|  | int | x,
|  | int | y,
|  | int | w,
|  | int | h,
|  | const char * | extra_options
| ) |  |

Create a new Ecore_Evas based on engine name and common parameters.

Parameters

  engine_name | engine name as returned by ecore_evas_engines_get() or `NULL` to use environment variable ECORE_EVAS_ENGINE, that can be undefined and in this case this call will try to find the first working engine.
  x | horizontal position of window (not supported in all engines)
  y | vertical position of window (not supported in all engines)
  w | width of window
  h | height of window
  extra_options | string with extra parameter, dependent on engines or @ NULL. String is usually in the form: 'key1=value1;key2=value2'. Pay attention that when getting that from shell commands, most consider ';' as the command terminator, so you need to escape it or use quotes.

Returns
  Ecore_Evas instance or `NULL` if creation failed.

References DBG, INF, and WRN.

EAPI void ecore_evas_alpha_set | ( | Ecore_Evas * | ee,
|  | Eina_Bool | alpha
| ) |  |

Set 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.

Referenced by ethumb_dup(), and ethumb_new().

EAPI Eina_Bool ecore_evas_alpha_get | ( | const Ecore_Evas * | ee | ) |

Query 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.

This function returns `EINA_TRUE` if `ee` has an alpha channel, and `EINA_FALSE` if it does not.

EAPI Ecore_Evas* ecore_evas_buffer_new | ( | int | w,
|  | int | h
| ) |  |

Create a new `Ecore_Evas` canvas bound to the Evas buffer engine.

Since
  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.

Examples:
  ecore_evas_buffer_example_01.c.

|  | const void * | data
| ) |  |

Create 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.

EAPI const void* ecore_evas_buffer_pixels_get | ( | Ecore_Evas * | ee | ) |

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

Parameters

  ee | An `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.

Examples:
  ecore_evas_buffer_example_01.c.

EAPI Ecore_Evas* ecore_evas_buffer_ecore_evas_parent_get | ( | Ecore_Evas * | ee | ) |

Return 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 parents.

EAPI Ecore_Evas* ecore_evas_ews_new | ( | int | x,
|  | int | y,
|  | int | w,
|  | int | h
| ) |  |

Create a new `Ecore_Evas` canvas bound to the Evas ews (Ecore + Evas Single Process Windowing System) engine.

EWS is a simple single process windowing system. The backing store is also an `Ecore_Evas` that can be setup with ecore_evas_ews_setup() and retrieved with ecore_evas_ews_ecore_evas_get(). It will allow window management using events prefixed with `ECORE_EVAS_EVENT_EWS_`.

The EWS windows (returned by this function or ecore_evas_new("ews"...)) will all be software buffer windows automatic rendered to the backing store.

Parameters

  x | horizontal position of window, in pixels
  y | vertical position of window, in pixels
  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

EAPI Evas_Object* ecore_evas_object_image_new | ( | Ecore_Evas * | ee_target | ) |

Create an Evas image object with image data bound to an own, internal `Ecore_Evas` canvas wrapper

Parameters

  ee_target | `Ecore_Evas` to have the canvas receiving the new image object

Returns
  A handle to the new image object

This will create a special Evas image object. The image's pixel array will get bound to the same image data array of an internal buffer `Ecore_Evas` canvas. The user of this function is, then, supposed to grab that `Ecore_Evas` handle, with ecore_evas_object_ecore_evas_get(), and use its canvas to render whichever contents he/she wants, independently of the contents of the canvas owned by `ee_target`. Those contents will reflect on the canvas of `ee`, though, being exactly the image data of the object returned by this function.

This is a helper function for the scenario of one wanting to grab a buffer canvas' contents (with ecore_evas_buffer_pixels_get()) to be used on another canvas, for whichever reason. The most common goal of this setup is to save an image file with a whole canvas as contents, which could not be achieved by using an image file within the target canvas.

Warning
  Always resize the returned image and its underlying `Ecore_Evas` handle accordingly. They must be kept with same sizes for things to work as expected. Also, you must issue `evas_object_image_size_set()` on the image with that same size. If the image is to be shown in a canvas bound to an engine different than the buffer one, then you must also set this image's fill properties accordingly.

Note
  The image returned will always be bound to the `EVAS_COLORSPACE_ARGB8888` colorspace, always.
  Use ecore_evas_object_evas_get() to grab the image's internal own canvas directly.
  If snapshoting this image's internal canvas, remember to flush its internal `Ecore_Evas` firstly, with ecore_evas_manual_render().

EAPI void ecore_evas_avoid_damage_set | ( | Ecore_Evas * | ee,
|  | Ecore_Evas_Avoid_Damage_Type | on
| ) |  |

Set whether or not an Ecore_Evas' window should avoid damage.

Parameters

  ee | The Ecore_Evas
  on | The type of the damage management

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. Possible options are:

- 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.

EAPI Eina_Bool ecore_evas_object_associate | ( | Ecore_Evas * | ee,
|  | Evas_Object * | obj,
|  | Ecore_Evas_Object_Associate_Flags | flags
| ) |  |

Associate the given object to this ecore evas.

Parameters

  ee | The Ecore_Evas to associate to obj
  obj | The object to associate to ee
  flags | The association flags.

Returns
  `EINA_TRUE` on success, `EINA_FALSE` otherwise.

Association means that operations on one will affect the other, for example moving the object will move the window, resize the object will also affect the ecore evas window, hide and show applies as well.

This is meant to simplify development, since you often need to associate these events with your "base" objects, background or bottom-most object.

Be aware that some methods might not be what you would like, deleting either the window or the object will delete the other. If you want to change that behavior, let's say to hide window when it's closed, you must use ecore_evas_callback_delete_request_set() and set your own code, like ecore_evas_hide(). Just remember that if you override delete_request and still want to delete the window/object, you must do that yourself.

Since we now define delete_request, deleting windows will not quit main loop, if you wish to do so, you should listen for EVAS_CALLBACK_FREE on the object, that way you get notified and you can call ecore_main_loop_quit().

Flags can be OR'ed of:

- ECORE_EVAS_OBJECT_ASSOCIATE_BASE (or 0): to listen to basic events like delete, resize and move, but no stacking or layer are used.
- ECORE_EVAS_OBJECT_ASSOCIATE_STACK: stacking operations will act on the Ecore_Evas, not the object. So evas_object_raise() will call ecore_evas_raise(). Relative operations (stack_above, stack_below) are still not implemented.
- ECORE_EVAS_OBJECT_ASSOCIATE_LAYER: stacking operations will act on the Ecore_Evas, not the object. So evas_object_layer_set() will call ecore_evas_layer_set().
- ECORE_EVAS_OBJECT_ASSOCIATE_DEL: the object delete will delete the ecore_evas as well as delete_requests on the ecore_evas will delete etc.
