Methods

Method	Description
IXRTimeline::AddCompletedEventHandler	Attaches a delegate to the Completed event for this timeline. When the Completed event is raised by this timeline, this delegate will be invoked.
IXRTimeline::GetAutoReverse	Retrieves a value that indicates whether the timeline plays in reverse after it completes a forward iteration.
IXRTimeline::GetBeginTime	Retrieves the time at which this timeline will begin.
IXRTimeline::GetDuration	Retrieves the total length of time that this timeline will play.
IXRTimeline::GetFillBehavior	Retrieves a value that specifies how the animation behaves after it reaches the end of its active period.
IXRTimeline::GetRepeatBehavior	Retrieves the repeating behavior of this timeline.
IXRTimeline::GetSpeedRatio	Retrieves the rate, in relation to its parent, at which time progresses for this timeline.
IXRTimeline::RemoveCompletedEventHandler	Removes a delegate from the Completed event for this timeline.
IXRTimeline::SetAutoReverse	Sets a value that indicates whether the timeline plays in reverse after it completes a forward iteration.
IXRTimeline::SetBeginTime	Sets the time at which this timeline will begin.
IXRTimeline::SetDuration	Sets the total length of time that this timeline will play.
IXRTimeline::SetFillBehavior	Sets a value that specifies how the animation behaves after it reaches the end of its active period.
IXRTimeline::SetRepeatBehavior	Sets the repeating behavior of this timeline.
IXRTimeline::SetSpeedRatio	Sets the rate, in relation to its parent, at which time progresses for this timeline.

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

IXRTimeline represents a segment of time. It provides functionality that enables you to specify to length of that segment, when it should start, how many times it will repeat, how fast time progresses in that segment, and more. Classes that derive from IXRTimeline provide animation functionality.

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