DiscreteObjectKeyFrame DiscreteObjectKeyFrame DiscreteObjectKeyFrame DiscreteObjectKeyFrame Class

Definition

Animates from the Object value of the previous key frame to its own Value using discrete values.

Remarks

Key-frame animations permit more than one target value that is reached at a point along the animation timeline. In other words each key frame can specify a different intermediate value, and the last key frame reached is the final animation value. By specifying multiple values to animate, you can make more complex animations.

DiscreteObjectKeyFrame is the only keyframe type permitted in an ObjectAnimationUsingKeyFrames. There are no linear interpolations or other interpolation logic that's possible for changing object values as the animation runs. The old object is removed at the KeyTime and the new object that is the value of the keyframe with that KeyTime replaces it.

There are several scenarios where using ObjectAnimationUsingKeyFrames rather than a typed animation is useful. Some of them are:

Methods

ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty)

Clears the local value of a dependency property.

(Inherited from DependencyObject)

GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) 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) GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty)

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

(Inherited from DependencyObject)

ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty)

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

(Inherited from DependencyObject)

RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) 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) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object)

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

(Inherited from DependencyObject)

UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64)

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

(Inherited from DependencyObject)

Properties

Dispatcher Dispatcher Dispatcher 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)

KeyTime KeyTime KeyTime KeyTime

Gets or sets the time at which the key frame's target Value should be reached.

(Inherited from ObjectKeyFrame)

KeyTimeProperty KeyTimeProperty KeyTimeProperty KeyTimeProperty

Identifies the KeyTime dependency property.

(Inherited from ObjectKeyFrame)

Value Value Value Value

Gets or sets the key frame's target value.

(Inherited from ObjectKeyFrame)

ValueProperty ValueProperty ValueProperty ValueProperty

Identifies the Value dependency property.
