UI 자동화 요소 이동
참고 항목
이 설명서는 System.Windows.Automation 네임스페이스에 정의된 관리되는 UI 자동화 클래스를 사용하려는 .NET Framework 개발자를 위한 것입니다. UI 자동화에 대한 최신 정보는 Windows 자동화 API: UI 자동화를 참조하세요.
이 예제에서는 UI 자동화 요소를 지정된 화면 위치로 이동하는 방법을 보여 줍니다.
예시
다음 예제에서는 WindowPattern 및 TransformPattern 컨트롤 패턴을 사용하여 프로그래밍 방식으로 Win32 대상 애플리케이션을 개별 화면 위치로 이동하고 BoundingRectanglePropertyAutomationPropertyChangedEvent를 추적합니다.
