Hinweise

Ein steuerbares Storyboard kann anhalten, fortsetzen, suchen, anhalten und entfernt werden.A controllable storyboard can pause, resume, seek, stop, and be removed. Um ein Storyboard im Code steuerbar zu machen, müssen Sie die entsprechende Überladung der- Begin Methode des Storyboards verwenden und angeben true , um es steuerbar zu machen.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. Ein Beispiel finden Sie unter Gewusst wie: Steuern eines Storyboards, nachdem esgestartet wurde.For an example, see How to: Control a Storyboard After It Starts.

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

Parameter

containingObject
FrameworkElement FrameworkElement FrameworkElement FrameworkElement

Das Objekt, auf das die angegebene frameworkTemplate angewendet wurde.The object to which the specified frameworkTemplate has been applied. Animationen ohne TargetName werden auf containingObject angewendet.Animations without a TargetName are applied to containingObject.

frameworkTemplate
FrameworkTemplate FrameworkTemplate FrameworkTemplate FrameworkTemplate

Die zu animierende Vorlage.The template to animate.

handoffBehavior
HandoffBehavior HandoffBehavior HandoffBehavior HandoffBehavior

Das Verhalten, das die neue Animation für die Interaktion mit aktuellen Animationen verwenden soll.The behavior the new animation should use to interact with any current animations.

isControllable
Boolean Boolean Boolean Boolean

true, wenn das Storyboard interaktiv steuerbar sein soll, andernfalls false.true if the storyboard should be interactively controllable; otherwise, false.

Hinweise

Um dieses Storyboard interaktiv zu steuern, müssen Sie beim Aufrufen containingObject der interaktiven Methoden, die Sie zum Starten des Storyboards verwendet haben, dasselbe angeben.To interactively control this storyboard, you must specify the same containingObject when calling the interactive methods that you used to begin the storyboard

Wenn diese Methode aufgerufen wird, Clock werden-Objekte für das Storyboard und alle darin enthaltenen Zeitachsen erstellt.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Diese Uhren werden mit containingObjectgespeichert.These clocks are stored with containingObject.

Beim Starten eines Storyboards werden CurrentStateInvalidated die CurrentGlobalSpeedInvalidated Ereignisse und ausgelöst.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Verwenden von Compose HandoffBehaviorUsing the Compose HandoffBehavior

Wenn StoryboardSie Clock , AnimationTimeline Compose oder AnimationClock auf eine Eigenschaft mithilfeHandoffBehaviorvon anwenden, verbrauchen alle Objekte, die dieser Eigenschaft zugeordnet sind, weiterhin Systemressourcen, das Zeit Steuerungssystem nicht. Entfernen Sie diese Uhren automatisch.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.

Um Leistungsprobleme zu vermeiden, wenn Sie eine große Anzahl von Uhren Composemithilfe von anwenden, sollten Sie das Verfassen von Uhren aus der animierten Eigenschaft entfernen, nachdem Sie fertiggestellt wurden.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. Es gibt mehrere Möglichkeiten, eine Uhr zu entfernen.There are several ways to remove a clock.

Dies betrifft hauptsächlich Animationen für Objekte, die eine lange Lebensdauer haben.This is primarily an issue for animations on objects that have a long lifetime. Wenn für ein Objekt eine Garbage Collection durchgeführt wird, werden auch die zugehörigen Uhren getrennt und die Garbage Collection erfolgt.When an object is garbage collected, its clocks are also disconnected and garbage collected.

Weitere Informationen zu Clock-Objekten finden Sie unter Übersicht über das Animations-und Zeit Steuerungssystem.For more information about clock objects, see Animation and Timing System Overview.

Hinweise

Um dieses Storyboard interaktiv zu steuern, müssen Sie beim Aufrufen containingObject der interaktiven Methoden, die Sie zum Starten des Storyboards verwendet haben, denselben Parameter verwenden.To interactively control this storyboard, you must use the same containingObject parameter when calling the interactive methods that you used to begin the storyboard

Wenn diese Methode aufgerufen wird, Clock werden-Objekte für das Storyboard und alle darin enthaltenen Zeitachsen erstellt.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Diese Uhren werden mit containingObjectgespeichert.These clocks are stored with containingObject.

Beim Starten eines Storyboards werden CurrentStateInvalidated die CurrentGlobalSpeedInvalidated Ereignisse und ausgelöst.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Verwenden von Compose HandoffBehaviorUsing the Compose HandoffBehavior

Wenn StoryboardSie Clock , AnimationTimeline Compose oder AnimationClock auf eine Eigenschaft mithilfeHandoffBehaviorvon anwenden, verbrauchen alle Objekte, die dieser Eigenschaft zugeordnet sind, weiterhin Systemressourcen, das Zeit Steuerungssystem nicht. Entfernen Sie diese Uhren automatisch.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.

Um Leistungsprobleme zu vermeiden, wenn Sie eine große Anzahl von Uhren Composemithilfe von anwenden, sollten Sie das Verfassen von Uhren aus der animierten Eigenschaft entfernen, nachdem Sie fertiggestellt wurden.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. Es gibt mehrere Möglichkeiten, eine Uhr zu entfernen.There are several ways to remove a clock.

Dies betrifft hauptsächlich Animationen für Objekte, die eine lange Lebensdauer haben.This is primarily an issue for animations on objects that have a long lifetime. Wenn für ein Objekt eine Garbage Collection durchgeführt wird, werden auch die zugehörigen Uhren getrennt und die Garbage Collection erfolgt.When an object is garbage collected, its clocks are also disconnected and garbage collected.

Hinweise

Wenn die Zieleigenschaften bereits animiert sind, werden Sie durch das angegebene Übergabe Verhalten ersetzt.If the targeted properties are already animated, they are replaced using the specified handoff behavior.

Um dieses Storyboard interaktiv zu steuern, müssen Sie beim Aufrufen containingObject der interaktiven Methoden, die Sie zum Starten des Storyboards verwendet haben, dasselbe angeben.To interactively control this storyboard, you must specify the same containingObject when calling the interactive methods that you used to begin the storyboard

Wenn diese Methode aufgerufen wird, Clock werden-Objekte für das Storyboard und alle darin enthaltenen Zeitachsen erstellt.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Diese Uhren werden mit containingObjectgespeichert.These clocks are stored with containingObject.

Beim Starten eines Storyboards werden CurrentStateInvalidated die CurrentGlobalSpeedInvalidated Ereignisse und ausgelöst.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Verwenden von Compose HandoffBehaviorUsing the Compose HandoffBehavior

Wenn StoryboardSie Clock , AnimationTimeline Compose oder AnimationClock auf eine Eigenschaft mithilfeHandoffBehaviorvon anwenden, verbrauchen alle Objekte, die dieser Eigenschaft zugeordnet sind, weiterhin Systemressourcen, das Zeit Steuerungssystem nicht. Entfernen Sie diese Uhren automatisch.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.

Um Leistungsprobleme zu vermeiden, wenn Sie eine große Anzahl von Uhren Composemithilfe von anwenden, sollten Sie das Verfassen von Uhren aus der animierten Eigenschaft entfernen, nachdem Sie fertiggestellt wurden.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. Es gibt mehrere Möglichkeiten, eine Uhr zu entfernen.There are several ways to remove a clock.

Dies betrifft hauptsächlich Animationen für Objekte, die eine lange Lebensdauer haben.This is primarily an issue for animations on objects that have a long lifetime. Wenn für ein Objekt eine Garbage Collection durchgeführt wird, werden auch die zugehörigen Uhren getrennt und die Garbage Collection erfolgt.When an object is garbage collected, its clocks are also disconnected and garbage collected.

Weitere Informationen zu Clock-Objekten finden Sie unter Übersicht über das Animations-und Zeit Steuerungssystem.For more information about clock objects, see Animation and Timing System Overview.

Ein Objekt, das im selben Namensbereich wie die Ziele der Animationen dieses Storyboards enthalten ist.An object contained within the same name scope as the targets of this storyboard's animations. Animationen ohne einen angegebenen TargetName werden auf containingObject angewendet.Animations without a specified TargetName are applied to containingObject.

handoffBehavior
HandoffBehavior HandoffBehavior HandoffBehavior HandoffBehavior

Das Verhalten, das die neue Animation für die Interaktion mit aktuellen Animationen verwenden soll.The behavior the new animation should use to interact with any current animations.

Beispiele

Im folgenden Beispiel wird verwendet SnapshotAndReplace HandoffBehavior , um zu animieren, Compose HandoffBehavior wenn der Benutzer mit der rechten Maustaste klickt.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
   instead.

'   left-clicks, the SnapshotAndReplace HandoffBehavior
'   is used when applying the animations. If the user
'   right-clicks, the Compose HandoffBehavior is used

Hinweise

Wenn StoryboardSie Clock , AnimationTimeline Compose oder AnimationClock auf eine Eigenschaft mithilfeHandoffBehaviorvon anwenden, verbrauchen alle Objekte, die dieser Eigenschaft zugeordnet sind, weiterhin Systemressourcen, das Zeit Steuerungssystem nicht. Entfernen Sie diese Uhren automatisch.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.

Um Leistungsprobleme zu vermeiden, wenn Sie eine große Anzahl von Uhren Composemithilfe von anwenden, sollten Sie das Verfassen von Uhren aus der animierten Eigenschaft entfernen, nachdem Sie fertiggestellt wurden.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. Es gibt mehrere Möglichkeiten, eine Uhr zu entfernen.There are several ways to remove a clock.

Dies betrifft hauptsächlich Animationen für Objekte, die eine lange Lebensdauer haben.This is primarily an issue for animations on objects that have a long lifetime. Wenn für ein Objekt eine Garbage Collection durchgeführt wird, werden auch die zugehörigen Uhren getrennt und die Garbage Collection erfolgt.When an object is garbage collected, its clocks are also disconnected and garbage collected.

Weitere Informationen zu Clock-Objekten finden Sie unter Übersicht über das Animations-und Zeit Steuerungssystem.For more information about clock objects, see Animation and Timing System Overview.

Wenn die Zieleigenschaften bereits animiert sind, werden Sie durch das SnapshotAndReplace Übergabe Verhalten ersetzt.If the targeted properties are already animated, they are replaced using the SnapshotAndReplace handoff behavior.

Um dieses Storyboard interaktiv zu steuern, müssen Sie beim Aufrufen containingObject der interaktiven Methoden, die Sie zum Starten des Storyboards verwendet haben, dasselbe angeben.To interactively control this storyboard, you must specify the same containingObject when calling the interactive methods that you used to begin the storyboard

Wenn diese Methode aufgerufen wird, Clock werden-Objekte für das Storyboard und alle darin enthaltenen Zeitachsen erstellt.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Diese Uhren werden mit containingObjectgespeichert.These clocks are stored with containingObject.

Hinweise

Wenn die Zieleigenschaften bereits animiert sind, werden Sie durch das SnapshotAndReplace Übergabe Verhalten ersetzt.If the targeted properties are already animated, they are replaced using the SnapshotAndReplace handoff behavior.

Mit dieser Methode gestartete Storyboards können nicht angehalten, fortgesetzt oder anderweitig interaktiv gesteuert werden, nachdem Sie gestartet wurden.Storyboards started with this method cannot be paused, resumed, or otherwise interactively controlled after they are started. Verwenden Sie die Begin -oder Begin -Methode, um ein Storyboard steuerbar zu machen.To make a storyboard controllable, use the Begin or Begin method.

Beim Starten eines Storyboards werden CurrentStateInvalidated die CurrentGlobalSpeedInvalidated Ereignisse und ausgelöst.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.

Begin() Begin() Begin() Begin()

Wendet die Animationen, die diesem Storyboard zugeordnet sind, auf ihre Ziele an und initiiert sie.Applies the animations associated with this Storyboard to their targets and initiates them.

public:
 void Begin();
public void Begin ();
member this.Begin : unit -> unit
Public Sub Begin ()

Begin(FrameworkElement, Boolean) Begin(FrameworkElement, Boolean) Begin(FrameworkElement, Boolean) Begin(FrameworkElement, Boolean)

Wendet die Animationen, die diesem Storyboard zugeordnet sind, auf ihre Ziele an und initiiert sie.Applies the animations associated with this Storyboard to their targets and initiates them.

public:
 void Begin(System::Windows::FrameworkElement ^ containingObject, bool isControllable);
public void Begin (System.Windows.FrameworkElement containingObject, bool isControllable);
member this.Begin : System.Windows.FrameworkElement * bool -> unit
Public Sub Begin (containingObject As FrameworkElement, isControllable As Boolean)

Parameter

containingObject
FrameworkElement FrameworkElement FrameworkElement FrameworkElement

Ein Objekt, das im selben Namensbereich wie die Ziele der Animationen dieses Storyboards enthalten ist.An object contained within the same name scope as the targets of this storyboard's animations. Animationen ohne TargetName werden auf containingObject angewendet.Animations without a TargetName are applied to containingObject.

isControllable
Boolean Boolean Boolean Boolean

true, wenn das Storyboard interaktiv steuerbar sein soll, andernfalls false.true if the storyboard should be interactively controllable; otherwise, false.

Hinweise

Wenn die Zieleigenschaften bereits animiert sind, werden Sie durch das SnapshotAndReplace Übergabe Verhalten ersetzt.If the targeted properties are already animated, they are replaced using the SnapshotAndReplace handoff behavior.

Um dieses Storyboard interaktiv zu steuern, müssen Sie beim Aufrufen containingObject der interaktiven Methoden, die Sie zum Starten des Storyboards verwendet haben, denselben Parameter verwenden.To interactively control this storyboard, you must use the same containingObject parameter when calling the interactive methods that you used to begin the storyboard

Wenn diese Methode aufgerufen wird, Clock werden-Objekte für das Storyboard und alle darin enthaltenen Zeitachsen erstellt.When this method is called, Clock objects are created for the storyboard and any timelines it contains. Diese Uhren werden mit containingObjectgespeichert.These clocks are stored with containingObject.

Beim Starten eines Storyboards werden CurrentStateInvalidated die CurrentGlobalSpeedInvalidated Ereignisse und ausgelöst.Beginning a storyboard triggers the CurrentStateInvalidated and CurrentGlobalSpeedInvalidated events.
