 * issued on it, all of its UI elements will get default values, when
 * declared on that file. To fetch an user's own, personal set of
 * those values, one gets to pair a <b>prefs data</b> handle to the
 * prefs widget. This is what this call is intended for.
 *
 * Prefs data values from @a prefs_data with keys matching the ones
 * present on the file passed on elm_prefs_file_set() to @a obj will
 * have their values applied to the respective UI elements of the
 * widget.
 *
 * When @a obj dies, the values of the elements declared on its @b
 * .epb file (the one set on elm_prefs_file_set()) marked as permanent
 * <b>will be written back</b> to @a prefs_data, if it is writable.
 * One is also able to make this writing event to take place
 * automatically after each UI element modification by using
 * elm_prefs_autosave_set().
 *
 * @note @a obj will keep a reference of its own for @a prefs_data,
 * but you should still unreference it by yourself, after the widget
 * is gone.
