Dear All,
This is Shinwoo Kim, learned that I could contribute to EFL! :)
I'm pleased to inform you that the patch for the "elm_diskselector".
Until now, the "elm_diskselector" only display 3 items at once,
if you accept this patch, the "elm_diskselector" can display more than 3
items.
For this feature, "elm_diskselector_display_item_num_set(Evas_Object *obj,
int num)" is added.
I would like to know more about your opinion about this feature. Thanks.
Sincerely,
Shinwoo Kim
