+ * @See_also: #GtkNotebook, #GtkStackSwitcher
+ *
+ * The GtkStack widget is a container which only shows
+ * one of its children at a time. In contrast to GtkNotebook,
+ * GtkStack does not provide a visible means for users
+ * to change the visible child. Instead, the #GtkStackSwitcher
+ * widget can be used with GtkStack to provide this functionality.
+ *
+ * Transitions between pages can be animated as slides or
+ * fades. This can be controlled with gtk_stack_set_transition_type().
+ * These animations respect the #GtkSettings::gtk-enable-animations
+ * setting.
+ *
+ * The GtkStack widget was added in GTK+ 3.10.
