Surface aims to show one of its connected circle objects.

The circle surface manages connected circle objects. When a circle object is chosen to be shown, the surface shows the circle object and hides the others. A circle object can be shown and received the rotary event on the surface by eext_rotary_object_event_activated_set() or evas_object_show().

The circle surface can be created by eext_circle_surface_conformant_add() and eext_circle_surface_layout_add().
