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

This collection is used as part of IXRColorAnimationUsingKeyFrames to animate a Color property value through a set of key frames over a specified duration. This collection describes the set of key-frame techniques that define an animation segment with a Color target value.

You can obtain a pointer to this collection by calling IXRColorAnimationUsingKeyFrames::GetKeyFrames. Then, you can use the methods to add, remove, or retrieve items. You can also clear the complete collection by calling the IXRColorKeyFrameCollection::Clearmethod.

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