ManipulationDelta.Translation 속성

정의

조작의 선형 동작을 가져오거나 설정합니다.

public:
 property System::Windows::Vector Translation { System::Windows::Vector get(); };
public System.Windows.Vector Translation { get; }
member this.Translation : System.Windows.Vector
Public ReadOnly Property Translation As Vector

속성 값

디바이스 독립적 단위(단위당 1/96인치)에서 조작의 선형 동작입니다.

예제

다음 예제에서는 이벤트 처리기는 ManipulationDelta 이벤트입니다. 예제에 적용 됩니다는 Translation, Scale, 및 Rotation 이동, 크기 조정 및 회전 속성을 Rectangle. 이 예제는에서 더 큰 예제의 일부 연습: 만드는 첫 번째 터치 애플리케이션합니다.
