This base class defines an animation segment that has its own target IXRDependencyObject value and uses the frame-transition method for an IXRObjectAnimationUsingKeyFrames object.

Syntax

class IXRObjectKeyFrame : public IXRDependencyObject

Methods

Method

Description

IXRObjectKeyFrame::GetKeyTime

Retrieves the time at which the target value of this key frame is reached.

IXRObjectKeyFrame::GetValue

Retrieves the target value for this key frame.

IXRObjectKeyFrame::SetKeyTime

Sets the time at which the target value of this key frame is reached.

IXRObjectKeyFrame::SetValue

Sets the target value for this key frame.

Thread Safety

Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

IXRObjectKeyFrame, the base class for IXRDiscreteObjectKeyFrame, defines a target value type that is derived from IXRDependencyObject. To animate an object derived from IXRDependencyObject by using key frames, define an IXRObjectAnimationUsingKeyFrames animation, and then populate its IXRObjectKeyFrameCollection with multiple IXRDiscreteObjectKeyFrame objects that define the key frames.

When you create a class instance, use an IXRObjectKeyFramePtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
