- * An index widget gives you an index for fast access to whichever
- * group of other UI items one might have. It's a list of text
- * items (usually letters, for alphabetically ordered access).
- *
- * Index widgets are by default hidden and just appear when the
- * user clicks over it's reserved area in the canvas. In its
- * default theme, it's an area one @ref Fingers "finger" wide on
- * the right side of the index widget's container.
- *
- * When items on the index are selected, smart callbacks get
- * called, so that its user can make other container objects to
- * show a given area or child object depending on the index item
- * selected. You'd probably be using an index together with @ref
- * List "lists", @ref Genlist "generic lists" or @ref Gengrid
- * "general grids".
- *
- * Smart events one can add callbacks for are:
- * - @c "changed" - When the selected index item changes. @c
- * event_info is the selected item's data pointer.
- * - @c "delay,changed" - When the selected index item changes, but
- * after a small idling period. @c event_info is the selected
- * item's data pointer.
- * - @c "selected" - When the user releases a mouse button and
- * selects an item. @c event_info is the selected item's data
- * pointer.
- * - @c "level,up" - when the user moves a finger from the first
- * level to the second level
- * - @c "level,down" - when the user moves a finger from the second
- * level to the first level
- *
- * The @c "delay,changed" event is so that it'll wait a small time
- * before actually reporting those events and, moreover, just the
- * last event happening on those time frames will actually be
- * reported.
- *
- * Here are some examples on its usage:
