IUiaScrollProvider Interface

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.
