The Scroll pattern exposes a control's ability to change the portion of its visible region that is visible to the user by scrolling its content. Examples: Listboxes TreeViews other containers that maintain a content area larger than the control's visible region Note that scrollbars themselves should not support the Scrollable pattern; they support the RangeValue pattern. Servers must normalize scrolling (0 to 100). This public interface represents UI elements that scroll their content.
