Thread Safety

Remarks

The IXRPointAnimationUsingKeyFrames class uses the IXRPointKeyFrameCollection to store IXRPointKeyFrame information. This collection describes the animation segments that animate an XRPoint with key frames.

You can obtain a pointer to this collection by calling IXRPointAnimationUsingKeyFrames::GetKeyFrames. Then, use the methods of this class to add, remove, or retrieve items. To clear the complete collection, call the IXRPointKeyFrameCollection::Clear method.

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

You can also define a point key-frame collection in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this collection in the source XAML for your application, see the PointAnimationUsingKeyFrames.KeyFrames Property on MSDN.
