-/**\r
- * @defgroup Navigationbar_ex Navigationbar_ex\r
- * @ingroup Elementary\r
- *\r
- * The NavigationBar_ex is an object that allows flipping (with animation) between 1 or\r
- * more pages of objects, much like a stack of windows within the window as well display\r
- * the title area for the page consisting of buttons, title, titleobjects etc:-.\r
- *\r
- * Objects can be pushed or popped from the stack or deleted as normal.\r
- * Pushes and pops will animate and a pop will delete the object once the\r
- * animation is finished if delete_on_pop is set else the content is unset and the\r
- * content pointer is sent as event information in the hide,finished signal.\r
- * Any object in the Navigationbar_ex can be promoted to the top\r
- * (from its current stacking position) as well. Objects are pushed to the\r
- * top with elm_navigationbar_ex_item_push() and when the top item is no longer\r
- * wanted, simply pop it with elm_navigationbar_ex_item_pop() and it will also be\r
- * deleted/unset depending on delete_on_pop variable.\r
- * Any object you wish to promote to the top that is already in the\r
- * navigationbar, simply use elm_navigationbar_ex_item_promote(). If an object is no longer\r
- * needed and is not the top item, just delete it as normal. You can query\r
- * which objects are the top and bottom with elm_navigationbar_ex_item_bottom_get()\r
- * and elm_navigationbar_ex_item_top_get().\r
