37 * @Title: CtkRevealer
38 * @See_also: #CtkExpander
39 *
40 * The CtkRevealer widget is a container which animates
41 * the transition of its child from invisible to visible.
42 *
43 * The style of transition can be controlled with
44 * ctk_revealer_set_transition_type().
45 *
46 * These animations respect the #CtkSettings:ctk-enable-animations
47 * setting.
48 *
49 * # CSS nodes
50 *
51 * CtkRevealer has a single CSS node with name revealer.
52 *
53 * The CtkRevealer widget was added in CTK+ 3.10.
