Uwagi

Scenorys z możliwością sterowania może wstrzymywać, wznawiać, wyszukiwać, zatrzymywać i usuwać. Aby umożliwić sterowanie scenorysem w kodzie, należy użyć odpowiedniego przeciążenia metody scenorysu Begin i określić true , aby można było go kontrolować. Aby zapoznać się z przykładem, zobacz How to: Control a Storyboard After It Starts (Instrukcje: kontrolowanie scenorysu po uruchomieniu).

Begin(FrameworkElement, FrameworkTemplate, HandoffBehavior, Boolean)

Stosuje animacje skojarzone z tym Storyboard elementem docelowym w określonym szablonie i inicjuje je.

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

Parametry

containingObject
FrameworkElement

Obiekt, do którego zastosowano określony frameworkTemplate obiekt. Animacje bez elementu TargetName są stosowane do elementu containingObject.

frameworkTemplate
FrameworkTemplate

Szablon do animowania.

handoffBehavior
HandoffBehavior

Zachowanie nowej animacji powinno służyć do interakcji z dowolnymi bieżącymi animacjami.

isControllable
Boolean

true jeśli scenorys powinien być interaktywnie sterowany; w przeciwnym razie , false.

Uwagi

Aby interaktywnie kontrolować ten scenorys, należy określić to samo containingObject podczas wywoływania interaktywnych metod użytych do rozpoczęcia scenorysu

Po wywołaniu Clock tej metody obiekty są tworzone dla scenorysu i wszelkich osi czasu, które zawiera. Te zegary są przechowywane za pomocą containingObjectpolecenia .

Rozpoczynanie scenorysu wyzwala zdarzenia CurrentStateInvalidated i CurrentGlobalSpeedInvalidated .

Korzystanie z Compose HandoffBehavior

Po zastosowaniu Storyboardwłaściwości , AnimationTimelinelub AnimationClock do właściwości przy użyciu ComposeHandoffBehavior, wszystkie Clock obiekty wcześniej skojarzone z tą właściwością nadal zużywają zasoby systemowe; system chronometrażu nie usuwa tych zegarów automatycznie.

Aby uniknąć problemów z wydajnością podczas stosowania dużej liczby zegarów przy użyciu , Composenależy usunąć tworzenie zegarów z animowanej właściwości po zakończeniu. Istnieje kilka sposobów usunięcia zegara.

Jest to przede wszystkim problem dotyczący animacji na obiektach, które mają długi okres istnienia. Gdy obiekt jest odśmiecany, jego zegary są również odłączone i wyrzucane śmieci.

Aby uzyskać więcej informacji na temat obiektów zegara, zobacz Animacja i System chronometrażu — omówienie.

Dotyczy

Begin(FrameworkElement, HandoffBehavior, Boolean)

Stosuje animacje skojarzone z tym Storyboard elementem docelowym i inicjuje je.

 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)

Parametry

containingObject
FrameworkElement

Obiekt znajdujący się w tym samym zakresie nazwy co obiekty docelowe animacji tego scenorysu. Animacje bez określonego TargetName elementu są stosowane do elementu containingObject.

handoffBehavior
HandoffBehavior

Zachowanie nowej animacji powinno służyć do interakcji z dowolnymi bieżącymi animacjami.

isControllable
Boolean

Deklaruje, czy animacja można kontrolować (można wstrzymać) po uruchomieniu.

Uwagi

Aby interaktywnie kontrolować ten scenorys, należy użyć tego samego containingObject parametru podczas wywoływania interaktywnych metod użytych do rozpoczęcia scenorysu

Po wywołaniu Clock tej metody obiekty są tworzone dla scenorysu i wszelkich osi czasu, które zawiera. Te zegary są przechowywane za pomocą containingObjectpolecenia .

Rozpoczynanie scenorysu wyzwala zdarzenia CurrentStateInvalidated i CurrentGlobalSpeedInvalidated .

Korzystanie z Compose HandoffBehavior

Po zastosowaniu Storyboardwłaściwości , AnimationTimelinelub AnimationClock do właściwości przy użyciu ComposeHandoffBehavior, wszystkie Clock obiekty wcześniej skojarzone z tą właściwością nadal zużywają zasoby systemowe; system chronometrażu nie usuwa tych zegarów automatycznie.

Aby uniknąć problemów z wydajnością podczas stosowania dużej liczby zegarów przy użyciu , Composenależy usunąć tworzenie zegarów z animowanej właściwości po zakończeniu. Istnieje kilka sposobów usunięcia zegara.

Jest to przede wszystkim problem dotyczący animacji na obiektach, które mają długi okres istnienia. Gdy obiekt jest odśmiecany, jego zegary są również odłączone i wyrzucane śmieci.

Uwagi

Jeśli właściwości docelowe są już animowane, są zastępowane przy użyciu określonego zachowania przekazywania.

Aby interaktywnie kontrolować ten scenorys, należy określić to samo containingObject podczas wywoływania interaktywnych metod użytych do rozpoczęcia scenorysu

Po wywołaniu Clock tej metody obiekty są tworzone dla scenorysu i wszelkich osi czasu, które zawiera. Te zegary są przechowywane za pomocą containingObjectpolecenia .

Rozpoczynanie scenorysu wyzwala zdarzenia CurrentStateInvalidated i CurrentGlobalSpeedInvalidated .

Korzystanie z Compose HandoffBehavior

Po zastosowaniu Storyboardwłaściwości , AnimationTimelinelub AnimationClock do właściwości przy użyciu ComposeHandoffBehavior, wszystkie Clock obiekty wcześniej skojarzone z tą właściwością nadal zużywają zasoby systemowe; system chronometrażu nie usuwa tych zegarów automatycznie.

Aby uniknąć problemów z wydajnością podczas stosowania dużej liczby zegarów przy użyciu , Composenależy usunąć tworzenie zegarów z animowanej właściwości po zakończeniu. Istnieje kilka sposobów usunięcia zegara.

Jest to przede wszystkim problem dotyczący animacji na obiektach, które mają długi okres istnienia. Gdy obiekt jest odśmiecany, jego zegary są również odłączone i wyrzucane śmieci.

Aby uzyskać więcej informacji na temat obiektów zegara, zobacz Animacja i System chronometrażu — omówienie.

Uwagi

Po zastosowaniu Storyboardwłaściwości , AnimationTimelinelub AnimationClock do właściwości przy użyciu ComposeHandoffBehavior, wszystkie Clock obiekty wcześniej skojarzone z tą właściwością nadal zużywają zasoby systemowe; system chronometrażu nie usuwa tych zegarów automatycznie.

Aby uniknąć problemów z wydajnością podczas stosowania dużej liczby zegarów przy użyciu , Composenależy usunąć tworzenie zegarów z animowanej właściwości po zakończeniu. Istnieje kilka sposobów usunięcia zegara.

Jest to przede wszystkim problem dotyczący animacji na obiektach, które mają długi okres istnienia. Gdy obiekt jest odśmiecany, jego zegary są również odłączone i wyrzucane śmieci.

Aby uzyskać więcej informacji na temat obiektów zegara, zobacz Animacja i System chronometrażu — omówienie.
