방법: 이미 시작된 Storyboard 제어
이 예제에서는 코드를 사용하여 Storyboard가 시작된 후 제어하는 방법을 보여 줍니다. XAML에서 스토리보드를 제어하려면 Trigger 및 TriggerAction 개체를 사용합니다. 예를 들어 이벤트 트리거를 사용하여 스토리보드가 시작된 후 제어를 참조하세요.
스토리보드를 시작하려면 스토리보드의 애니메이션을 애니메이션 효과를 주는 속성에 배포하고 스토리보드를 시작하는 Begin 메서드를 사용합니다.
스토리보드를 제어할 수 있도록 하려면 Begin 메서드를 사용하고 true를 두 번째 매개 변수로 지정합니다. 그런 다음, 스토리보드의 대화형 메서드를 사용하여 스토리보드에 일시 중지, 다시 시작, 검색, 중지, 가속화 또는 속도 저하를 수행하거나, 채우기 기간으로 앞당길 수 있습니다. 다음은 스토리보드의 대화형 메서드 목록입니다.
Pause: 스토리보드를 일시 중지합니다.
Resume: 일시 중지된 스토리보드를 다시 시작합니다.
SetSpeedRatio: 스토리보드의 대화형 속도를 설정합니다.
Seek: 지정된 위치의 스토리보드를 찾습니다.
SeekAlignedToLastTick: 스토리보드를 지정된 위치로 찾습니다. Seek 메서드와 달리 이 작업은 다음 틱 전에 처리됩니다.
SkipToFill: 스토리보드를 해당 채우기 기간으로 앞당깁니다.
Stop: 스토리보드를 중지합니다.
다음 예제에서는 여러 스토리보드 메서드가 스토리보드를 대화형으로 제어하는 데 사용됩니다.
