  * This widget emits the following signals, besides the ones sent from
  * @ref Layout:
+ * @li @c "toggled" : When the panel has been toggled. (since 1.18)
  * @li @c "scroll" : When the content has been scrolled (moved). (since 1.10)
  *        This signal is emitted only when the panel is scrollable.
  *        Elm_Panel_Scroll_Info will be passed by @p event_info argument.
