ITransformProvider interface

Applies to Windows and Windows Phone

Exposes methods and properties to support access by a Microsoft UI Automation client to controls or elements that can be moved, resized, or rotated within a two-dimensional space. Implement this interface in order to support the capabilities that an automation client requests with a GetPattern call and PatternInterface.Transform.

Remarks

This pattern has guidelines and conventions that aren't fully documented here. For more info on what this pattern is for, see Transform Control Pattern.

ITransformProvider isn't implemented by any existing Windows Runtime automation peers. The interface exists so that custom control authors can support the automation pattern in a custom control, and implement their automation support using the same Windows Runtime managed or C++ APIs as they use to define control logic or other automation support.

Use the TransformPatternIdentifiers class if you want to reference the ITransformProvider pattern properties from control code when you call RaisePropertyChangedEvent.
