Un guion gráfico controlable puede pausar, reanudar, buscar, detener y quitar.A controllable storyboard can pause, resume, seek, stop, and be removed. Para que un guion gráfico pueda controlarse en el código, debe usar la sobrecarga adecuada del método Begin del guión gráfico true y especificar para que sea controlable.To make a storyboard controllable in code, you must use the appropriate overload of the storyboard's Begin method and specify true to make it controllable. Como ejemplo, vea Cómo: Controlar un guión gráfico después desu inicio.For an example, see How to: Control a Storyboard After It Starts.

Parámetros

containingObject
FrameworkElement

El objeto al que se ha aplicado el parámetro frameworkTemplate especificado.The object to which the specified frameworkTemplate has been applied. Las animaciones que no disponen de TargetName se aplican a containingObject.Animations without a TargetName are applied to containingObject.

frameworkTemplate
FrameworkTemplate

Plantilla que se va a animar.The template to animate.

handoffBehavior
HandoffBehavior

Comportamiento que la nueva animación debe utilizar para interactuar con las animaciones actuales.The behavior the new animation should use to interact with any current animations.

isControllable
Boolean

true si el guión gráfico debe controlarse de forma interactiva; de lo contrario, false.true if the storyboard should be interactively controllable; otherwise, false.

Comentarios

Para controlar de forma interactiva este guión gráfico, debe especificar el containingObject mismo cuando llame a los métodos interactivos que usó para comenzar el guión gráfico.To interactively control this storyboard, you must specify the same containingObject when calling the interactive methods that you used to begin the storyboard

Cuando se llama a este método Clock , se crean objetos para el guión gráfico y las escalas de tiempo que contiene.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Estos relojes se almacenan con containingObject.These clocks are stored with containingObject.

Al iniciar un guión gráfico, CurrentStateInvalidated se CurrentGlobalSpeedInvalidated desencadenan los eventos y.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Usar el HandoffBehavior ComposeUsing the Compose HandoffBehavior

Cuando se aplica un Storyboard, AnimationTimelineo AnimationClock a una propiedad mediante el Compose HandoffBehavior, todos los Clock objetos asociados previamente a esa propiedad continúan consumiendo recursos del sistema; el sistema de control de tiempo no Quite estos relojes automáticamente.When you apply a Storyboard, AnimationTimeline, or AnimationClock to a property using the Compose HandoffBehavior, any Clock objects previously associated with that property continue to consume system resources; the timing system does not remove these clocks automatically.

Para evitar problemas de rendimiento al aplicar un gran número de relojes mediante Compose, debe quitar los relojes de composición de la propiedad animada una vez completados.To avoid performance issues when you apply a large number of clocks using Compose, you should remove composing clocks from the animated property after they complete. Hay varias formas de quitar un reloj.There are several ways to remove a clock.

Este problema se produce principalmente en las animaciones de objetos que tienen un período de duración prolongado.This is primarily an issue for animations on objects that have a long lifetime. Cuando un objeto se recolecta como elemento no utilizado, sus relojes también se desconectan y se recolectan los elementos no utilizados.When an object is garbage collected, its clocks are also disconnected and garbage collected.

Para obtener más información sobre los objetos de reloj, consulte información general sobre sistemas de control de tiempo y animación.For more information about clock objects, see Animation and Timing System Overview.

Begin(FrameworkElement, HandoffBehavior, Boolean)

SnapshotAndReplace En el ejemplo siguiente HandoffBehavior se usa para animar cuando el usuario Compose HandoffBehavior hace clic con el botón primario y cuando el usuario hace clic con el botón secundario del mouse.The next example uses the SnapshotAndReplace HandoffBehavior to animate when the user left-clicks, and the Compose HandoffBehavior when the user right-clicks.

/*

   This sample animates the position of an ellipse when 
   the user clicks within the main border. If the user
   left-clicks, the SnapshotAndReplace HandoffBehavior
   is used when applying the animations. If the user
   right-clicks, the Compose HandoffBehavior is used
   instead.

Para controlar interactivamente este guión gráfico, debe usar el mismo containingObject parámetro al llamar a los métodos interactivos que usó para comenzar el guión gráfico.To interactively control this storyboard, you must use the same containingObject parameter when calling the interactive methods that you used to begin the storyboard

Cuando se llama a este método Clock , se crean objetos para el guión gráfico y las escalas de tiempo que contiene.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Estos relojes se almacenan con containingObject.These clocks are stored with containingObject.

Al iniciar un guión gráfico, CurrentStateInvalidated se CurrentGlobalSpeedInvalidated desencadenan los eventos y.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Si las propiedades de destino ya están animadas, se reemplazan con el comportamiento de entrega especificado.If the targeted properties are already animated, they are replaced using the specified handoff behavior.

Para controlar de forma interactiva este guión gráfico, debe especificar el containingObject mismo cuando llame a los métodos interactivos que usó para comenzar el guión gráfico.To interactively control this storyboard, you must specify the same containingObject when calling the interactive methods that you used to begin the storyboard

Cuando se llama a este método Clock , se crean objetos para el guión gráfico y las escalas de tiempo que contiene.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Estos relojes se almacenan con containingObject.These clocks are stored with containingObject.

Al iniciar un guión gráfico, CurrentStateInvalidated se CurrentGlobalSpeedInvalidated desencadenan los eventos y.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Usar el HandoffBehavior ComposeUsing the Compose HandoffBehavior

Cuando se aplica un Storyboard, AnimationTimelineo AnimationClock a una propiedad mediante el Compose HandoffBehavior, todos los Clock objetos asociados previamente a esa propiedad continúan consumiendo recursos del sistema; el sistema de control de tiempo no Quite estos relojes automáticamente.When you apply a Storyboard, AnimationTimeline, or AnimationClock to a property using the Compose HandoffBehavior, any Clock objects previously associated with that property continue to consume system resources; the timing system does not remove these clocks automatically.

Para evitar problemas de rendimiento al aplicar un gran número de relojes mediante Compose, debe quitar los relojes de composición de la propiedad animada una vez completados.To avoid performance issues when you apply a large number of clocks using Compose, you should remove composing clocks from the animated property after they complete. Hay varias formas de quitar un reloj.There are several ways to remove a clock.

Este problema se produce principalmente en las animaciones de objetos que tienen un período de duración prolongado.This is primarily an issue for animations on objects that have a long lifetime. Cuando un objeto se recolecta como elemento no utilizado, sus relojes también se desconectan y se recolectan los elementos no utilizados.When an object is garbage collected, its clocks are also disconnected and garbage collected.

Para obtener más información sobre los objetos de reloj, consulte información general sobre sistemas de control de tiempo y animación.For more information about clock objects, see Animation and Timing System Overview.

SnapshotAndReplace En el ejemplo siguiente HandoffBehavior se usa para animar cuando el usuario Compose HandoffBehavior hace clic con el botón primario y cuando el usuario hace clic con el botón secundario del mouse.The following example uses the SnapshotAndReplace HandoffBehavior to animate when the user left-clicks, and the Compose HandoffBehavior when the user right-clicks.

/*

   This sample animates the position of an ellipse when 
   the user clicks within the main border. If the user
   left-clicks, the SnapshotAndReplace HandoffBehavior
   is used when applying the animations. If the user
   right-clicks, the Compose HandoffBehavior is used

Comentarios

Cuando se aplica un Storyboard, AnimationTimelineo AnimationClock a una propiedad mediante el Compose HandoffBehavior, todos los Clock objetos asociados previamente a esa propiedad continúan consumiendo recursos del sistema; el sistema de control de tiempo no Quite estos relojes automáticamente.When you apply a Storyboard, AnimationTimeline, or AnimationClock to a property using the Compose HandoffBehavior, any Clock objects previously associated with that property continue to consume system resources; the timing system does not remove these clocks automatically.

Para evitar problemas de rendimiento al aplicar un gran número de relojes mediante Compose, debe quitar los relojes de composición de la propiedad animada una vez completados.To avoid performance issues when you apply a large number of clocks using Compose, you should remove composing clocks from the animated property after they complete. Hay varias formas de quitar un reloj.There are several ways to remove a clock.

Este problema se produce principalmente en las animaciones de objetos que tienen un período de duración prolongado.This is primarily an issue for animations on objects that have a long lifetime. Cuando un objeto se recolecta como elemento no utilizado, sus relojes también se desconectan y se recolectan los elementos no utilizados.When an object is garbage collected, its clocks are also disconnected and garbage collected.

Para obtener más información sobre los objetos de reloj, consulte información general sobre sistemas de control de tiempo y animación.For more information about clock objects, see Animation and Timing System Overview.

Si las propiedades de destino ya están animadas, se reemplazan SnapshotAndReplace con el comportamiento de entrega.If the targeted properties are already animated, they are replaced using the SnapshotAndReplace handoff behavior.

Los guiones gráficos que se inician con este método no se pueden pausar, reanudar ni controlar interactivamente una vez iniciados.Storyboards started with this method cannot be paused, resumed, or otherwise interactively controlled after they are started. Para que un guion gráfico pueda controlarse, Begin use Begin el método o.To make a storyboard controllable, use the Begin or Begin method.

Al iniciar un guión gráfico, CurrentStateInvalidated se CurrentGlobalSpeedInvalidated desencadenan los eventos y.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Begin()

Aplica las animaciones asociadas con este Storyboard a sus destinos y las inicia.Applies the animations associated with this Storyboard to their targets and initiates them.

Para controlar interactivamente este guión gráfico, debe usar el mismo containingObject parámetro al llamar a los métodos interactivos que usó para comenzar el guión gráfico.To interactively control this storyboard, you must use the same containingObject parameter when calling the interactive methods that you used to begin the storyboard

Cuando se llama a este método Clock , se crean objetos para el guión gráfico y las escalas de tiempo que contiene.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Estos relojes se almacenan con containingObject.These clocks are stored with containingObject.
