void eext_object_event_callback_add ( Evas_Object obj,
Eext_Callback_Type  type,
Eext_Event_Cb  func,
void *  data 
)

Add (register) a callback function to a given evas object.

This function adds a function callback to an object when the key event occurs on object obj. The key event on the object is only triggered when the object is the most top in objects stack and visible. This means, like the naviframe widget, if your application needs to have the events based on the view but not focus, you can use this callback. A callback function must have the Eext_Event_Cb prototype definition. The first parameter (data) in this definition will have the same value passed to eext_object_event_callback_add() as the data parameter, at runtime. The second parameter obj is the evas object on which event occurred. Finally, the third parameter event_info is a pointer to a data structure that may or may not be passed to the callback, depending on the event type that triggered the callback. This is so because some events don't carry extra context with them, but others do.

Parameters:
[in]objevas object.
[in]typeThe type of event that will trigger the callback.
[in]funcThe function to be called when the key event is triggered.
[in]dataThe data pointer to be passed to func.
See also:
eext_object_event_callback_del()
Since :
2.3.1

Delete a callback function from an object.

This function removes the most recently added callback from the object obj which was triggered by the type type and was calling the function func when triggered. If the removal is successful it will also return the data pointer that was passed to eext_object_event_callback_add() when the callback was added to the object. If not successful NULl will be returned.

Parameters:
[in]objObject to remove a callback from.
[in]typeThe type of event that was triggering the callback.
[in]funcThe function that was to be called when the event was triggered
Returns:
data The data pointer that was to be passed to the callback.
