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

Use this collection with IXRObjectAnimationUsingKeyFrames to animate an object, such as a button or rectangle, along with a set of key frames. This collection describes the set of key frames that define a storyboard animation segment with an Object target value.

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

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

You can define an object 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 ObjectAnimationUsingKeyFrames Class on MSDN.
