-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm coding a small program just to learn the Ecore, Evas and Edje libraries. I saw that some callback functions accept additional data as input parameters. For example:
EAPI Ecore_Event *ecore_event_add(int type, void *ev, void (*func_free) (void *data, void *ev), void *data); But other callbacks don't, like the next one: EAPI void ecore_evas_callback_resize_set(Ecore_Evas *ee, void (*func) (Ecore_Evas *ee)); As I wish to avoid the use of global variables, I set a pointer to the necessary data into the Evas instance with the function: evas_data_attach_set(evas, data); Then, each time I need this data and it's not available as input parameter in the callback function, I do: My_Data *data = (My_Data *)(evas_data_attach_get(ecore_evas_get(ee))); where ee is the Ecore_Evas instance. Is this use of evas_data_attach_get/set correct? Is there a better solution? Whouldn't it be useful to have something like: EAPI void ecore_evas_callback_resize_set(Ecore_Evas *ee, void (*func) (Ecore_Evas *ee, void *data), void *data); Thanks in advance. - -- Fabio G.
