* Set an attached data pointer to an object with a given string key.
|
||||
* @param obj The object to attach the data pointer to
|
||||
* @param key The string key for the data to access it
|
||||
* @param data The ponter to the data to be attached
|
||||
*
|
||||
* This attaches the pointer @p data to the object @p obj given the string
|
||||
* @p key. This pointer will stay "hooked" to the object until a new pointer
|
||||
* with the same string key is attached with evas_object_data_set() or it is
|
||||
* deleted with evas_object_data_del(). On deletion of the object @p obj, the
|
||||
* pointers will not be accessible from the object anymore.
|
||||
*
|
||||
* You can find the pointer attached under a string key using
|
||||
* evas_object_data_get(). It is the job of the calling application to free
|
||||
* any data pointed to by @p data when it is no longer required.
|
||||
*
|
||||
* If @p data is NULL, the old value stored at @p key will be removed but no
|
||||
* new value will be stored. This is synonymous with calling
|
||||
* evas_object_data_del() with @p obj and @p key.
|
||||
*
|
||||
* Example:
|
||||
*
|
||||
* @code
|
||||
* int *my_data;
|
||||
* extern Evas_Object *obj;
|
||||
*
|
||||
* my_data = malloc(500);
|
||||
* evas_object_data_set(obj, "name_of_data", my_data);
|
||||
* printf("The data that was attached was %p\n", evas_object_data_get(obj, "name_of_data"));
|
||||
* @endcode
