* This object display a list of object (generally a list of images) and some actions like
*
* The slideshow use 2 callbacks to create and delete the objects displayed. When an item
* is displayed the function itc->func.get() is called. This function should create the object,
- * for example the object can be an evas_object_image or a photocam. When a object is no more
- * displayed the function itc->func.del() is called, the user can delete or hide the object here.
- * If itc->func.del is NULL the slideshow delete the object with evas_object_del().
+ * for example the object can be an evas_object_image or a photocam. When an object is no more
+ * displayed the function itc->func.del() is called, the user can delete the dana associated to the item.
+ *
+ * Signals that you can add callbacks for are:
+ *
+ * "changed" - when the slideshow switch to another item
