AnimationClock Class
Maintains the run-time state of an AnimationTimeline and processes its output values.

Assembly: PresentationCore (in PresentationCore.dll)
The AnimationClock type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Controller | Gets a ClockController that can be used to start, pause, resume, seek, skip, stop, or remove this Clock. (Inherited from Clock.) |
![]() | CurrentGlobalSpeed | Gets the rate at which the clock's time is currently progressing, compared to real-world time. (Inherited from Clock.) |
![]() | CurrentGlobalTime | Gets the current global time, as established by the WPF timing system. (Inherited from Clock.) |
![]() | CurrentIteration | Get the current iteration of this clock. (Inherited from Clock.) |
![]() | CurrentProgress | Gets the current progress of this Clock within its current iteration. (Inherited from Clock.) |
![]() | CurrentState | Gets a value indicating whether the clock is currently Active, Filling, or Stopped. (Inherited from Clock.) |
![]() | CurrentTime | Gets this clock's current time within its current iteration. (Inherited from Clock.) |
![]() | Dispatcher | Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.) |
![]() | HasControllableRoot | Gets a value that indicates whether this Clock is part of a controllable clock tree. (Inherited from Clock.) |
![]() | IsPaused | Gets a value that indicates whether this Clock, or any of its parents, is paused. (Inherited from Clock.) |
![]() | NaturalDuration | Gets the natural duration of this clock's Timeline. (Inherited from Clock.) |
![]() | Parent | Gets the clock that is the parent of this clock. (Inherited from Clock.) |
![]() | Timeline | Gets the AnimationTimeline that describes this clock's behavior. |
| Name | Description | |
|---|---|---|
![]() | CheckAccess | Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.) |
![]() | DiscontinuousTimeMovement | When implemented in a derived class, will be invoked whenever a clock repeats, skips, or seeks. (Inherited from Clock.) |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetCanSlip | Returns whether the Clock has its own external time source, which may require synchronization with the timing system. (Inherited from Clock.) |
![]() | GetCurrentTimeCore | Gets this clock's current time within its current iteration. (Inherited from Clock.) |
![]() | GetCurrentValue | Gets the current output value of the AnimationClock. |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | SpeedChanged | When implemented in a derived class, will be invoked whenever a clock begins, skips, pauses, resumes, or when the clock's SpeedRatio is modified. (Inherited from Clock.) |
![]() | Stopped | When implemented in a derived class, will be invoked whenever a clock is stopped using the Stop method. (Inherited from Clock.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | VerifyAccess | Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.) |
| Name | Description | |
|---|---|---|
![]() | Completed | Occurs when this clock has completely finished playing. (Inherited from Clock.) |
![]() | CurrentGlobalSpeedInvalidated | Occurs when the clock's speed is updated. (Inherited from Clock.) |
![]() | CurrentStateInvalidated | Occurs when the clock's CurrentState property is updated. (Inherited from Clock.) |
![]() | CurrentTimeInvalidated | Occurs when this clock's CurrentTime becomes invalid. (Inherited from Clock.) |
![]() | RemoveRequested | Occurs when the Remove method is called on this Clock or one of its parent clocks. (Inherited from Clock.) |
AnimationClock objects are generated from AnimationTimeline objects. An AnimationTimeline describes an animation's output values, duration, begin time, end time, and other fundamental animation information. An AnimationClock processes the animation values described by an AnimationTimeline object.
This example shows how to use Clock objects to animate a property.
There are three ways to animate a dependency property:
Create an AnimationTimeline and associate it with that property by using a Storyboard.
Use the object's BeginAnimation method to apply a single AnimationTimeline to a target property.
Create an AnimationClock from an AnimationTimeline and apply it to a property.
Storyboard objects and the BeginAnimation method enable you to animate properties without directly creating and distributing clocks (for examples, see How to: Animate a Property by Using a Storyboard and How to: Animate a Property Without Using a Storyboard); clocks are created and distributed for you automatically.
The following example shows how to create an AnimationClock and apply it to two similar properties.
For an example showing how to interactively control a Clock after it starts, see How to: Interactively Control a Clock.
