7 * This widget holds 2 content objects(Evas_Object): one on the front and one
8 * on the back. It allows you to flip from front to back and vice-versa using
11 * If either the front or back contents are not set the flip will treat that
12 * as transparent. So if you wore to set the front content but not the back,
13 * and then call elm_flip_go() you would see whatever is below the flip.
15 * For a list of supported animations see elm_flip_go().
17 * Signals that you can add callbacks for are:
18 * "animate,begin" - when a flip animation was started
19 * "animate,done" - when a flip animation is finished
21 * @ref tutorial_flip show how to use most of the API.
