Efl Extension Circle Scroller

Circle scroller is based on elm_scroller and is scrolled by rotary event.

Circle scroller is to visualize and utilize scroll effect for elm_scroller. While elm_scroller provides scrollbar with straight horizontal/vertical movement, circle scroller provides scrollbar with circular movement. Rotary event can be activated by eext_rotary_object_event_activated_set(), circle scroller scrolls 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.
  • "horizontal,scroll,bar": Horizontal scroll bar circle item.
  • "horizontal,scroll,bg": Horizontal scroll background circle item.
