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
