Storyboard.Pause 方法

定義

命名空間:

System.Windows.Media.Animation

組件:

PresentationFramework.dll

暫停與這個 Clock 所建立的 Storyboard。

多載

Pause()	暫停與這個 Clock 所建立的 Storyboard。
Pause(FrameworkContentElement)	暫停與這個 Storyboard 相關聯之指定 FrameworkContentElement 的 Clock。
Pause(FrameworkElement)	暫停與這個 Storyboard 相關聯之指定 FrameworkElement 的 Clock。

Pause()

暫停與這個 Clock 所建立的 Storyboard。

public:
 void Pause();

public void Pause ();

member this.Pause : unit -> unit

Public Sub Pause ()

備註

這個方法會暫停分鏡腳本，但如果腳本不是使用中或目前暫停，則不會有明顯的效果。 副作用是，所有相關聯的子系也會暫停。

可控制的分鏡腳本可以暫停、繼續、搜尋、停止和移除。 若要在程式碼中控制分鏡 Begin 腳本，您必須使用腳本方法的適當多載，並指定 true 以使其可控制。 如需範例，請參閱 如何：在腳本啟動之後控制分鏡腳本。

開始暫停的分鏡腳本

當您 Begin 暫停的分鏡腳本時，它似乎會繼續並重新啟動。 不過，這不是實際發生的情況。 方法 Begin 實際上會將暫停 Storyboard 的 取代為新的未暫停版本。 每次呼叫 方法時 Begin ，都會為分鏡腳本建立時鐘物件。 這些時鐘會散發到其動畫的屬性。 因此，當再次呼叫 方法時 Begin ，它不會重新開機其時鐘;它會以新的時鐘取代它們。

Pause(FrameworkContentElement)

暫停與這個 Storyboard 相關聯之指定 FrameworkContentElement 的 Clock。

public:
 void Pause(System::Windows::FrameworkContentElement ^ containingObject);

public void Pause (System.Windows.FrameworkContentElement containingObject);

member this.Pause : System.Windows.FrameworkContentElement -> unit

Public Sub Pause (containingObject As FrameworkContentElement)

參數

containingObject

FrameworkContentElement

呼叫 Begin(FrameworkContentElement, Boolean) 方法時指定的物件。 此物件包含為這個腳本和其子系所建立的 Clock 物件。

範例

下列範例使用可控制的分鏡腳本來建立 TextEffect 動畫。 TextEffect包含在 FrameworkContentElement 的名稱範圍內。

備註

這個方法會暫停分鏡腳本，但如果腳本不是使用中或目前暫停，則不會有明顯的效果。 副作用是，所有相關聯的子系也會暫停。

搜尋暫停的分鏡腳本不會繼續。 繼續暫停分鏡腳本的唯一方法是使用 Resume 方法。 Begin再次呼叫 方法會將暫停的分鏡腳本取代為新的腳本，其外觀為繼續腳本。

若要以互動方式控制此分鏡腳本，您必須在呼叫您用來開始分鏡腳本的互動式方法時使用相同的 containingObject 參數。 可控制的分鏡腳本可以暫停、繼續、搜尋、停止和移除。 若要在程式碼中控制分鏡 Begin 腳本，您必須使用腳本方法的適當多載，並指定 true 以使其可控制。 例如，請參閱 如何：在腳本啟動之後控制分鏡腳本。

暫停分鏡腳本的時鐘會 CurrentGlobalSpeedInvalidated 觸發事件。

開始暫停的分鏡腳本

當您 Begin 暫停的分鏡腳本時，它似乎會繼續並重新啟動。 不過，這不是實際發生的情況。 方法 Begin 實際上會以未暫停的版本取代本身。 每次呼叫 方法時 Begin ，都會為分鏡腳本建立時鐘物件。 這些時鐘會散發到其動畫的屬性。 因此，當再次呼叫 方法時 Begin ，它不會重新開機其時鐘;它會以新的時鐘取代它們。
