방법: Storyboard를 사용하여 속성에 애니메이션 효과 주기

이 예제에서는 Storyboard를 사용하여 속성에 애니메이션 효과를 주는 방법을 보여 줍니다. Storyboard를 사용하여 속성에 애니메이션 효과를 주려면 애니메이션 효과를 주려는 각 속성에 대한 애니메이션을 생성하고 해당 애니메이션을 포함할 Storyboard도 생성합니다.

속성 형식에 따라 사용할 애니메이션 형식이 결정됩니다. 예를 들어 Double 값을 사용하는 속성에 애니메이션 효과를 주려면 DoubleAnimation을 사용합니다. TargetName 및 TargetProperty 연결된 속성은 애니메이션이 적용되는 개체와 속성을 지정합니다.

XAML(Extensible Application Markup Language)에서 스토리보드를 시작하려면 BeginStoryboard 작업과 EventTrigger를 사용합니다. EventTrigger는 해당 RoutedEvent 속성으로 지정된 이벤트가 발생하면 BeginStoryboard 작업을 시작합니다. BeginStoryboard 작업이 Storyboard를 시작합니다.

다음 예제에서는 Storyboard 개체를 사용하여 두 개의 Button 컨트롤에 애니메이션 효과를 줍니다. 첫 번째 단추의 크기를 변경하려면 해당 단추의 Width에 애니메이션 효과가 적용됩니다. 두 번째 단추의 색상을 변경하려면 SolidColorBrush의 Color 속성을 사용하여 애니메이션 효과가 적용되는 단추의 Background를 설정합니다.

참고

애니메이션은 FrameworkElement 개체(예: Control 또는 Panel) 및 Freezable 개체(예: Brush 또는 Transform) 모두를 대상으로 할 수 있지만 프레임워크 요소만 Name 속성을 가집니다. 애니메이션의 대상으로 지정될 수 있게 freezable에 이름을 할당하려면 이전 예제와 같이 x:Name 지시문을 사용합니다.

코드를 사용하는 경우 FrameworkElement에 대해 NameScope을 생성하고 해당 FrameworkElement로 애니메이션 효과를 적용할 개체의 이름을 등록해야 합니다. 코드에서 애니메이션을 시작하려면 EventTrigger로 BeginStoryboard 작업을 사용합니다. 필요에 따라 이벤트 처리기와 Storyboard의 Begin 메서드를 사용할 수 있습니다. 다음 예제에서는 Begin 메서드를 사용하는 방법을 보여 줍니다.

애니메이션 및 Storyboard에 대한 자세한 내용은 애니메이션 개요를 참조하세요.

코드를 사용하는 경우 속성에 애니메이션 효과를 주기 위해 Storyboard 개체만 사용하도록 제한되지 않습니다. 자세한 내용 및 예제에 대해서는 Storyboard를 사용하지 않고 속성에 애니메이션 효과 주기 및 AnimationClock을 사용하여 속성에 애니메이션 효과 적용을 참조하세요.
