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).
15 * Signals that you can add callbacks for are:
17 * "dismissed" - the ctxpopup was dismissed
