* Elementary has the following styles for the hover widget:
* @li default
* @li menu
* @li hoversel_vertical
*
- * The following are the available position for content:
- * @li left
- * @li top-left
- * @li top
- * @li top-right
- * @li right
- * @li bottom-right
- * @li bottom
- * @li bottom-left
- * @li middle
- * @li smart
- *
- * Signals that you can add callbacks for are:
- * @li "clicked" - the user clicked the empty space in the hover to dismiss
- * @li "smart,changed" - a content object placed under the "smart"
- * policy was replaced to a new slot direction.
- *
- * Default content parts of the hover widget that you can use for are:
- * @li "left"
- * @li "top-left"
- * @li "top"
- * @li "top-right"
- * @li "right"

+ * This widget inherits from the @ref Layout one, so that all the
+ * functions acting on it also work for hover objects.
+ *
+ * This widget emits the following signals, besides the ones sent from
+ * @ref Layout :
+ * @li @c "clicked" - The user clicked the empty space in the hover to dismiss.
