Remarks

Setting the Duration property has no effect on this object as the duration is preconfigured.

PointerDownThemeAnimation overrides the current values of Projection and RenderTransform.

Windows 8.1 and prior Projection and RenderTransform are not affected by PointerDownThemeAnimation.

Constructors

PointerDownThemeAnimation()

Initializes a new instance of the PointerDownThemeAnimation class.

Properties

AutoReverse

Gets or sets a value that indicates whether the timeline plays in reverse after it completes a forward iteration.

(Inherited from Timeline)
BeginTime

Gets or sets the time at which this Timeline should begin.

(Inherited from Timeline)
Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

(Inherited from DependencyObject)
Duration

Gets or sets the length of time for which this timeline plays, not counting repetitions.

(Inherited from Timeline)
FillBehavior

Gets or sets a value that specifies how the animation behaves after it reaches the end of its active period.

(Inherited from Timeline)
RepeatBehavior

Gets or sets the repeating behavior of this timeline.

(Inherited from Timeline)
SpeedRatio

Gets or sets the rate, relative to its parent, at which time progresses for this Timeline.

(Inherited from Timeline)
TargetName

Gets or sets the reference name of the control element being targeted.

TargetNameProperty

Identifies the TargetName dependency property.

Methods

ClearValue(DependencyProperty)

Clears the local value of a dependency property.

(Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)

Returns any base value established for a dependency property, which would apply in cases where an animation is not active.

(Inherited from DependencyObject)
GetValue(DependencyProperty)

Returns the current effective value of a dependency property from a DependencyObject.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if a local value is set.

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)

Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance.

(Inherited from DependencyObject)
SetValue(DependencyProperty, Object)

Sets the local value of a dependency property on a DependencyObject.

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)

Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.

(Inherited from DependencyObject)

Events
