Tenga en cuenta que establecer la propiedad Duration no tiene ningún efecto en este objeto, ya que la duración está preconfigurada.

Constructores

SwipeBackThemeAnimation()

Inicializa una nueva instancia de la clase SwipeBackThemeAnimation .

Propiedades

AutoReverse	Obtiene o establece un valor que indica si la escala de tiempo se reproduce en orden inverso después de completar una iteración de avance. (Heredado de Timeline)
BeginTime	Obtiene o establece la hora en la que debe comenzar esta escala de tiempo . (Heredado de Timeline)
Dispatcher	Obtiene el CoreDispatcher al que está asociado este objeto. CoreDispatcher representa una instalación que puede tener acceso a DependencyObject en el subproceso de interfaz de usuario incluso si un subproceso que no es de interfaz de usuario inicia el código. (Heredado de DependencyObject)
Duration	Obtiene o establece la duración para la que se reproduce esta escala de tiempo, sin contar las repeticiones. (Heredado de Timeline)
FillBehavior	Obtiene o establece un valor que especifica cómo se comporta la animación después de que llegue al final de su período activo. (Heredado de Timeline)
FromHorizontalOffset	Obtiene o establece la distancia por la que el destino se traduce en la dirección horizontal cuando la animación está activa.
FromHorizontalOffsetProperty	Identifica la propiedad de dependencia FromHorizontalOffset .
FromVerticalOffset	Obtiene o establece la distancia por la que el destino se traduce en la dirección vertical cuando la animación está activa.
FromVerticalOffsetProperty	Identifica la propiedad de dependencia FromHorizontalOffset .
RepeatBehavior	Obtiene o establece el comportamiento de repetición de esta escala de tiempo. (Heredado de Timeline)
SpeedRatio	Obtiene o establece la velocidad, en relación con su elemento primario, en cuyo momento progresa para esta escala de tiempo. (Heredado de Timeline)
TargetName	Obtiene o establece el nombre de referencia del elemento de control de destino.
TargetNameProperty	Identifica la propiedad de dependencia TargetName .

Métodos

ClearValue(DependencyProperty)	Borra el valor local de una propiedad de dependencia. (Heredado de DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Devuelve cualquier valor base establecido para una propiedad de dependencia, que se aplicaría en los casos en los que una animación no está activa. (Heredado de DependencyObject)
GetValue(DependencyProperty)	Devuelve el valor efectivo actual de una propiedad de dependencia de dependencyObject. (Heredado de DependencyObject)
ReadLocalValue(DependencyProperty)	Devuelve el valor local de una propiedad de dependencia, si se establece un valor local. (Heredado de DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registra una función de notificación para escuchar los cambios en una dependencyProperty específica en esta instancia de DependencyObject . (Heredado de DependencyObject)
SetValue(DependencyProperty, Object)	Establece el valor local de una propiedad de dependencia en dependencyObject. (Heredado de DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancela una notificación de cambio registrada anteriormente llamando a RegisterPropertyChangedCallback. (Heredado de DependencyObject)

Eventos

Completed

Se produce cuando se ha completado la reproducción del objeto Storyboard . (Heredado de Timeline)
