Remarques

Notez que la définition de la propriété Duration n’a aucun effet sur cet objet, car la durée est préconfigurée.

Constructeurs

SwipeBackThemeAnimation()

Initialise une nouvelle instance de la classe SwipeBackThemeAnimation.

Propriétés

AutoReverse

Obtient ou définit une valeur qui indique si la chronologie est lue en sens inverse après avoir effectué une itération vers l’avant.

(Hérité de Timeline)
BeginTime

Obtient ou définit l’heure à laquelle cette chronologie doit commencer.

(Hérité de Timeline)
Dispatcher

Obtient le CoreDispatcher auquel cet objet est associé. CoreDispatcher représente une fonctionnalité qui peut accéder à DependencyObject sur le thread d’interface utilisateur, même si le code est initié par un thread autre que l’interface utilisateur.

(Hérité de DependencyObject)
Duration

Obtient ou définit la durée de cette chronologie, sans prendre en compte les répétitions.

(Hérité de Timeline)
FillBehavior

Obtient ou définit une valeur qui spécifie le comportement de l’animation une fois qu’elle a atteint la fin de sa période active.

(Hérité de Timeline)
FromHorizontalOffset

Obtient ou définit la distance par laquelle la cible est traduite dans le sens horizontal lorsque l’animation est active.

FromHorizontalOffsetProperty

Identifie la propriété de dépendance FromHorizontalOffset .

FromVerticalOffset

Obtient ou définit la distance par laquelle la cible est traduite dans la direction verticale lorsque l’animation est active.

FromVerticalOffsetProperty

Identifie la propriété de dépendance FromHorizontalOffset .

RepeatBehavior

Obtient ou définit le comportement à répétition de cette chronologie.

(Hérité de Timeline)
SpeedRatio

Obtient ou définit la vitesse, par rapport à son parent, à laquelle progresse pour cette chronologie.

(Hérité de Timeline)
TargetName

Obtient ou définit le nom de référence de l’élément de contrôle ciblé.

TargetNameProperty

Identifie la propriété de dépendance TargetName .

Méthodes

ClearValue(DependencyProperty)

Efface la valeur locale d’une propriété de dépendance.

(Hérité de DependencyObject)
GetAnimationBaseValue(DependencyProperty)

Retourne toute valeur de base établie pour une propriété de dépendance, qui s’appliquerait dans les cas où une animation n’est pas active.

(Hérité de DependencyObject)
GetValue(DependencyProperty)

Retourne la valeur effective actuelle d’une propriété de dépendance à partir d’un DependencyObject.

(Hérité de DependencyObject)
ReadLocalValue(DependencyProperty)

Retourne la valeur locale d’une propriété de dépendance, si une valeur locale est définie.

(Hérité de DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)

Inscrit une fonction de notification pour écouter les modifications apportées à un DependencyProperty spécifique sur ce instance DependencyObject.

(Hérité de DependencyObject)
SetValue(DependencyProperty, Object)

Définit la valeur locale d’une propriété de dépendance sur un DependencyObject.

(Hérité de DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)
