備註

可控制的分鏡腳本可以暫停、繼續、搜尋、停止及移除。若要在程式碼中控制分鏡腳本，您必須使用分鏡腳本方法的適當 Begin 多載，並指定 true 使其可控制。如需範例，請參閱如何：在腳本啟動時控制分鏡腳本。

Begin(FrameworkElement, FrameworkTemplate, HandoffBehavior, Boolean)

將與這個 Storyboard 相關聯的動畫套用至指定範本內的目標並加以初始化。

public:
 void Begin(System::Windows::FrameworkElement ^ containingObject, System::Windows::FrameworkTemplate ^ frameworkTemplate, System::Windows::Media::Animation::HandoffBehavior handoffBehavior, bool isControllable);

public void Begin (System.Windows.FrameworkElement containingObject, System.Windows.FrameworkTemplate frameworkTemplate, System.Windows.Media.Animation.HandoffBehavior handoffBehavior, bool isControllable);

member this.Begin : System.Windows.FrameworkElement * System.Windows.FrameworkTemplate * System.Windows.Media.Animation.HandoffBehavior * bool -> unit

Public Sub Begin (containingObject As FrameworkElement, frameworkTemplate As FrameworkTemplate, handoffBehavior As HandoffBehavior, isControllable As Boolean)

參數

containingObject: FrameworkElement

已套用所指定 frameworkTemplate 的物件。不具有 TargetName 的動畫才會套用至 containingObject。

frameworkTemplate: FrameworkTemplate

要顯示動畫的範本。

handoffBehavior: HandoffBehavior

新動畫的行為應用來與任何目前的動畫進行互動。

isControllable: Boolean

如果腳本應該要以互動方式控制，則為 true；否則為 false。

備註

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，指定相同的 containingObject

呼叫這個方法時， Clock 會建立腳本的物件及其包含的任何時程表。這些時鐘會以 containingObject 儲存。

開始分鏡腳本會 CurrentStateInvalidated 觸發和 CurrentGlobalSpeedInvalidated 事件。

使用 Compose HandoffBehavior

當您使用 HandoffBehavior Compose 將、 AnimationTimeline 或 AnimationClock 套用 Storyboard 至屬性時，先前與該屬性相關聯的任何 Clock 物件都會繼續取用系統資源;計時系統不會自動移除這些時鐘。

若要避免使用套用 Compose 大量時鐘時的效能問題，您應該在動畫屬性完成之後，從動畫屬性中移除撰寫時鐘。有幾個方式可移除時鐘。

若要從屬性中移除所有時鐘，請使用 ApplyAnimationClock(DependencyProperty, AnimationClock) 動畫物件的或 BeginAnimation(DependencyProperty, AnimationTimeline) 方法。指定要以動畫顯示的屬性做為第一個參數，並 null 指定為第二個參數。這會從屬性中移除所有動畫時鐘。
若要從時鐘清單中移除特定 AnimationClock ，請使用 Controller 的 AnimationClock 屬性來擷取 ClockController ，然後呼叫 Remove 的 ClockController 方法。這通常是在時鐘的 Completed 事件處理常式中完成。請注意，只有根時鐘可以由 ClockController 控制; Controller 子時鐘的屬性會傳 null 回。另請注意， Completed 如果時鐘的有效持續時間為永久，則不會呼叫事件。在此情況下，使用者必須判斷何時呼叫 Remove 。

這主要是在存留期較長的物件才會發生的動畫問題。當物件被垃圾收集時，其時鐘也會中斷連線並垃圾收集。

如需時鐘物件的詳細資訊，請參閱動畫和計時系統概觀。

適用於

Begin(FrameworkElement, HandoffBehavior, Boolean)

將與這個 Storyboard 相關聯的動畫套用至其目標並加以初始化。

public:
 void Begin(System::Windows::FrameworkElement ^ containingObject, System::Windows::Media::Animation::HandoffBehavior handoffBehavior, bool isControllable);

public void Begin (System.Windows.FrameworkElement containingObject, System.Windows.Media.Animation.HandoffBehavior handoffBehavior, bool isControllable);

member this.Begin : System.Windows.FrameworkElement * System.Windows.Media.Animation.HandoffBehavior * bool -> unit

Public Sub Begin (containingObject As FrameworkElement, handoffBehavior As HandoffBehavior, isControllable As Boolean)

參數

containingObject: FrameworkElement

物件，包含在與這個分鏡腳本動畫目標相同的名稱範圍內。沒有指定之 TargetName 的動畫會套用至 containingObject。

handoffBehavior: HandoffBehavior

新動畫的行為應用來與任何目前的動畫進行互動。

isControllable: Boolean

宣告在動畫啟動後，是否可以控制 (暫停) 該動畫。

備註

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

呼叫這個方法時， Clock 會建立腳本的物件及其包含的任何時程表。這些時鐘會以 containingObject 儲存。

開始分鏡腳本會 CurrentStateInvalidated 觸發和 CurrentGlobalSpeedInvalidated 事件。

使用 Compose HandoffBehavior

若要避免使用套用 Compose 大量時鐘時的效能問題，您應該在動畫屬性完成之後，從動畫屬性中移除撰寫時鐘。有幾個方式可移除時鐘。

若要從屬性中移除所有時鐘，請使用 ApplyAnimationClock(DependencyProperty, AnimationClock) 動畫物件的或 BeginAnimation(DependencyProperty, AnimationTimeline) 方法。指定要以動畫顯示的屬性做為第一個參數，並 null 指定為第二個參數。這會從屬性中移除所有動畫時鐘。
若要從時鐘清單中移除特定 AnimationClock ，請使用 Controller 的 AnimationClock 屬性來擷取 ClockController ，然後呼叫 Remove 的 ClockController 方法。這通常是在時鐘的 Completed 事件處理常式中完成。請注意，只有根時鐘可以由 ClockController 控制; Controller 子時鐘的屬性會傳 null 回。另請注意， Completed 如果時鐘的有效持續時間為永久，則不會呼叫事件。在此情況下，使用者必須判斷何時呼叫 Remove 。

這主要是在存留期較長的物件才會發生的動畫問題。當物件被垃圾收集時，其時鐘也會中斷連線並垃圾收集。

如需時鐘物件的詳細資訊，請參閱動畫和計時系統概觀。

備註

如果目標屬性已經以動畫顯示，則會使用指定的遞交行為來取代它們。

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，指定相同的 containingObject

呼叫這個方法時， Clock 會建立腳本的物件及其包含的任何時程表。這些時鐘會以 containingObject 儲存。

開始分鏡腳本會 CurrentStateInvalidated 觸發和 CurrentGlobalSpeedInvalidated 事件。

使用 Compose HandoffBehavior

若要避免使用套用 Compose 大量時鐘時的效能問題，您應該在動畫屬性完成之後，從動畫屬性中移除撰寫時鐘。有幾個方式可移除時鐘。

若要從屬性中移除所有時鐘，請使用 ApplyAnimationClock(DependencyProperty, AnimationClock) 動畫物件的或 BeginAnimation(DependencyProperty, AnimationTimeline) 方法。指定要以動畫顯示的屬性做為第一個參數，並 null 指定為第二個參數。這會從屬性中移除所有動畫時鐘。
若要從時鐘清單中移除特定 AnimationClock ，請使用 Controller 的 AnimationClock 屬性來擷取 ClockController ，然後呼叫 Remove 的 ClockController 方法。這通常是在時鐘的 Completed 事件處理常式中完成。請注意，只有根時鐘可以由 ClockController 控制; Controller 子時鐘的屬性會傳 null 回。另請注意， Completed 如果時鐘的有效持續時間為永久，則不會呼叫事件。在此情況下，使用者必須判斷何時呼叫 Remove 。

這主要是在存留期較長的物件才會發生的動畫問題。當物件被垃圾收集時，其時鐘也會中斷連線並垃圾收集。

如需時鐘物件的詳細資訊，請參閱動畫和計時系統概觀。

適用於

Begin(FrameworkElement, FrameworkTemplate)

將與這個 Storyboard 相關聯的動畫套用至指定範本內的目標並加以初始化。

public:
 void Begin(System::Windows::FrameworkElement ^ containingObject, System::Windows::FrameworkTemplate ^ frameworkTemplate);

public void Begin (System.Windows.FrameworkElement containingObject, System.Windows.FrameworkTemplate frameworkTemplate);

member this.Begin : System.Windows.FrameworkElement * System.Windows.FrameworkTemplate -> unit

Public Sub Begin (containingObject As FrameworkElement, frameworkTemplate As FrameworkTemplate)

參數

containingObject: FrameworkElement

已套用所指定 frameworkTemplate 的物件。不具有 TargetName 的動畫才會套用至 containingObject。

frameworkTemplate: FrameworkTemplate

要顯示動畫的範本。

備註

如果目標屬性已經以動畫顯示，則會使用 SnapshotAndReplace 遞交行為來取代它們。

呼叫這個方法時， Clock 會建立腳本的物件及其包含的任何時程表。這些時鐘會以 containingObject 儲存。

開始分鏡腳本會 CurrentStateInvalidated 觸發和 CurrentGlobalSpeedInvalidated 事件。

適用於

Begin(FrameworkElement, HandoffBehavior)

使用指定的 Storyboard，將與這個 HandoffBehavior 相關聯的動畫套用至目標並加以初始化。

public:
 void Begin(System::Windows::FrameworkElement ^ containingObject, System::Windows::Media::Animation::HandoffBehavior handoffBehavior);

public void Begin (System.Windows.FrameworkElement containingObject, System.Windows.Media.Animation.HandoffBehavior handoffBehavior);

member this.Begin : System.Windows.FrameworkElement * System.Windows.Media.Animation.HandoffBehavior -> unit

Public Sub Begin (containingObject As FrameworkElement, handoffBehavior As HandoffBehavior)

參數

containingObject: FrameworkElement

物件，包含在與這個分鏡腳本動畫目標相同的名稱範圍內。沒有指定之 TargetName 的動畫會套用至 containingObject。

handoffBehavior: HandoffBehavior

新動畫的行為應用來與任何目前的動畫進行互動。

範例

下列範例會使用 SnapshotAndReplace HandoffBehavior 在使用者按一下滑鼠左鍵時產生動畫效果，以及 Compose HandoffBehavior 使用者以滑鼠右鍵按一下時的。

備註

若要避免使用套用 Compose 大量時鐘時的效能問題，您應該在動畫屬性完成之後，從動畫屬性中移除撰寫時鐘。有幾個方式可移除時鐘。

若要從屬性中移除所有時鐘，請使用 ApplyAnimationClock(DependencyProperty, AnimationClock) 動畫物件的或 BeginAnimation(DependencyProperty, AnimationTimeline) 方法。指定要以動畫顯示的屬性做為第一個參數，並 null 指定為第二個參數。這會從屬性中移除所有動畫時鐘。
若要從時鐘清單中移除特定 AnimationClock ，請使用 Controller 的 AnimationClock 屬性來擷取 ClockController ，然後呼叫 Remove 的 ClockController 方法。這通常是在時鐘的 Completed 事件處理常式中完成。請注意，只有根時鐘可以由 ClockController 控制; Controller 子時鐘的屬性會傳 null 回。另請注意， Completed 如果時鐘的有效持續時間為永久，則不會呼叫事件。在此情況下，使用者必須判斷何時呼叫 Remove 。

這主要是在存留期較長的物件才會發生的動畫問題。當物件被垃圾收集時，其時鐘也會中斷連線並垃圾收集。

如需時鐘物件的詳細資訊，請參閱動畫和計時系統概觀。

備註

如果目標屬性已經以動畫顯示，則會使用 SnapshotAndReplace 遞交行為來取代它們。

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，指定相同的 containingObject

呼叫這個方法時， Clock 會建立腳本的物件及其包含的任何時程表。這些時鐘會以 containingObject 儲存。

開始分鏡腳本會 CurrentStateInvalidated 觸發和 CurrentGlobalSpeedInvalidated 事件。

適用於

Begin(FrameworkElement)

將與這個 Storyboard 相關聯的動畫套用至其目標並加以初始化。

public:
 void Begin(System::Windows::FrameworkElement ^ containingObject);

public void Begin (System.Windows.FrameworkElement containingObject);

member this.Begin : System.Windows.FrameworkElement -> unit

Public Sub Begin (containingObject As FrameworkElement)

參數

containingObject: FrameworkElement

物件，包含在與這個分鏡腳本動畫目標相同的名稱範圍內。不具有 TargetName 的動畫才會套用至 containingObject。

備註

如果目標屬性已經以動畫顯示，則會使用 SnapshotAndReplace 遞交行為來取代它們。

以這個方法啟動的分鏡腳本無法在啟動後暫停、繼續或以互動方式控制。若要讓分鏡腳本成為可控制，請使用 Begin(FrameworkElement, Boolean) 或 Begin(FrameworkElement, HandoffBehavior, Boolean) 方法。

開始分鏡腳本會 CurrentStateInvalidated 觸發和 CurrentGlobalSpeedInvalidated 事件。

適用於

Begin(FrameworkContentElement)

將與這個 Storyboard 相關聯的動畫套用至其目標並加以初始化。

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

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

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

Public Sub Begin (containingObject As FrameworkContentElement)

參數

containingObject: FrameworkContentElement

物件，包含在與這個分鏡腳本動畫目標相同的名稱範圍內。不具有 TargetName 的動畫才會套用至 containingObject。

範例

下列範例會使用分鏡腳本建立動畫 TextEffect 。 TextEffect包含在 FrameworkContentElement 的名稱範圍內。

如果目標屬性已經以動畫顯示，則會使用 SnapshotAndReplace 遞交行為來取代它們。

以這個方法啟動的分鏡腳本無法在啟動後暫停、繼續或以互動方式控制。若要讓分鏡腳本成為可控制，請使用 Begin 或 Begin 方法。

開始分鏡腳本會 CurrentStateInvalidated 觸發和 CurrentGlobalSpeedInvalidated 事件。
