|
* @brief Context popup widget.
|
|
*
|
|
* A ctxpopup is a widget that, when shown, pops up a list of items.
|
|
* It automatically chooses an area inside its parent object's view
|
|
* (set via elm_ctxpopup_add() and elm_ctxpopup_hover_parent_set()) to
|
|
* optimally fit into it. In the default theme, it will also point an
|
|
* arrow to it's top left position at the time one shows it. Ctxpopup
|
|
* items have a label and/or an icon. It is intended for a small
|
|
* number of items (hence the use of list, not genlist).
|
|
*
|
|
* @note Ctxpopup is a specialization of @ref Hover.
|
|
*
|
|
* Signals that you can add callbacks for are:
|
|
* "dismissed" - the ctxpopup was dismissed
|
|
*
|
|
* Default content parts of the ctxpopup widget that you can use for are:
|
|
* @li "default" - A content of the ctxpopup
|
|
*
|
|
* Default content parts of the ctxpopup items that you can use for are:
|
|
* @li "icon" - An icon in the title area
|
|
*
|
|
* Default text parts of the ctxpopup items that you can use for are:
|
|
* @li "default" - Title label in the title area
|
|

* Supported elm_object common APIs.
