ee The Ecore_Evas to activate.

This functions activates the Ecore_Evas.

EAPI int ecore_evas_alpha_get (const Ecore_Evas * ee)

Query whether an Ecore_Evas has an alpha channel. Parameters:

ee The Ecore_Evas to query.

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

Associate the given object to this ecore evas. 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.

Parameters:

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

Returns:

1 on success, 0 otherwise.
