   5  * @defgroup Ctxpopup
   6  *
   7  * A ctxpopup is a widget that, when shown, pops up a list of items.
   8  * It automatically chooses an area inside its parent object's view
   9  * (set via elm_ctxpopup_add() and elm_ctxpopup_hover_parent_set()) to
  10  * optimally fit into it. In the default theme, it will also point an
  11  * arrow to the cursor position at the time one shows it. Ctxpopup
  12  * items have a label and/or an icon. It is intended for a small
  13  * number of items (hence the use of list, not genlist).
  14  *
  15  * Signals that you can add callbacks for are:
  16  *
  17  * "dismissed" - the ctxpopup was dismissed
