/**
 * @defgroup SegmentControl SegmentControl
 *
 * SegmentControl Widget is a horizontal control made of multiple segment items,
 * each segment item functioning similar to discrete two state button. A segment
 * control groups the the items together and provides compact single button with
 * multiple equal size segments. Segment item size is determined by base widget
 * size and the number of items added.
 * Only one Segment item can be at selected state. A segment item can display
 * combination of Text and any Evas_Object like Images or other widget.
 *
 * Signals that you can add callbacks for are:
 *
 * "changed" -when the user clicks on a segment item which is not previously
 *            selected and get selected. The event_info parameter is the
 *            segment item index.
