Comentários

Esse método pausa o storyboard, mas não tem efeito discerníveis se ele não estiver ativo ou em pausa no momento.This method pauses the storyboard, but has no discernible effect if it is not active or currently paused. Como um efeito colateral, todos os filhos associados também são pausados.As a side effect, all associated children are also paused.

Um storyboard controlável pode pausar, retomar, buscar, parar e ser removido.A controllable storyboard can pause, resume, seek, stop, and be removed. Para tornar um storyboard controlável no código, você deve usar a sobrecarga apropriada do método do Begin storyboard e especificar true para torná-lo controlável.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. Para obter um exemplo, consulte Controle um storyboard depois que eleé iniciado.For an example, see How to: Control a Storyboard After It Starts.

Iniciando um storyboard pausadoBeginning a Paused Storyboard

Quando você Begin tem um storyboard em pausa, ele parece retomar e reiniciar.When you Begin a storyboard that was paused, it appears to resume and restart. No entanto, isso não é o que realmente acontece.However, that is not what actually happens. O Begin método realmente substitui o Storyboard em pausa por uma nova versão não pausada.The Begin method actually replaces the paused Storyboard with a new unpaused version. Cada vez que Begin o método é chamado, os objetos de relógio são criados para o storyboard.Each time the Begin method is called, clock objects are created for the storyboard. Esses relógios são distribuídos para as propriedades que eles animam.These clocks are distributed to the properties they animate. Portanto, quando o Begin método é chamado novamente, ele não reinicia seus relógios; ele os substitui por novos relógios.So, when the Begin method is called again, it does not restart its clocks; it replaces them with new clocks.

Pause(FrameworkContentElement)

Pausa o Clock do FrameworkContentElement especificado associado a este Storyboard.Pauses the Clock of the specified FrameworkContentElement associated with this Storyboard.

Parâmetros

containingObject
FrameworkContentElement

O objeto especificado quando o método Begin(FrameworkContentElement, Boolean) foi chamado.The object specified when the Begin(FrameworkContentElement, Boolean) method was called. Esse objeto contém os objetos Clock que foram criados para esse storyboard e seus filhos.This object contains the Clock objects that were created for this storyboard and its children.

Exemplos

O exemplo a seguir usa um storyboard controlável para animar um TextEffect.The following example uses a controllable storyboard to animate a TextEffect. O TextEffect está contido no escopo FrameworkContentElementde nome de um.The TextEffect is contained within a FrameworkContentElement's name scope.

Esse método pausa o storyboard, mas não tem efeito discerníveis se ele não estiver ativo ou em pausa no momento.This method pauses the storyboard, but has no discernible effect if it is not active or currently paused. Como um efeito colateral, todos os filhos associados também são pausados.As a side effect, all associated children are also paused.

Procurar um storyboard pausado não o retoma.Seeking a paused storyboard does not resume it. A única maneira de retomar um storyboard pausado é usar o Resume método.The only way to resume a paused storyboard is to use the Resume method. Chamar o Begin método novamente substitui o storyboard pausado por um novo, que tem a aparência de retomá-lo.Calling the Begin method again replaces the paused storyboard with a new one, which has the appearance of resuming it.

Para controlar interativamente esse storyboard, você deve usar o mesmo containingObject parâmetro ao chamar os métodos interativos que você usou para iniciar o storyboard.To interactively control this storyboard, you must use the same containingObject parameter when calling the interactive methods that you used to begin the storyboard.
