Efl Extension Circle Genlist

Circle genlist is based on elm_genlist and is scrolled by rotary event.

Circle genlist is to visualize and utilize scroll effect for elm_genlist. While elm_genlist provides scrollbar with straight horizontal/vertical movement, circle genlist provides scrollbar with circular movement. Rotary event can be activated by eext_rotary_object_event_activated_set(), circle genlist scrolls genlist items upward/leftward responding to counter clockwise rotary event, and scrolls downward/rightward responding to clockwise rotary event.

The available circle object items are as follows:

  • "default": Default circle item. It draws vertical scroll bar.
  • "vertical,scroll,bg": Vertical scroll background circle item.
