XRDuration (Windows Embedded CE 6.0)

1/6/2010

This structure defines how long a timeline will play one time.

Syntax

struct XRDuration{
  enum _DurationType{
        DurationType_Automatic,
        DurationType_TimeSpan,
        DurationType_Forever
  };

    XRTimeSpan TimeSpan;
  _DurationType DurationType;
};

Members

• DurationType
  Indicates the duration type as follows:

  • DurationType_Automatic
    The duration is determined automatically.
  • DurationType_TimeSpan
    The duration is contained in the TimeSpan member.
  • DurationType_Forever
    The duration is infinite. Deprecated.

• TimeSpan
  An XRTimeSpan value that indicates the duration.

Remarks

You can set XRDuration on a storyboard or animation by using IXRTimeline::SetDuration.

If you use DurationType_Automatic for a storyboard, the timeline continues until the last child animation ends. If you use DurationType_Automatic for an animation, the time span is 1 second. You can use this setting during debugging to verify that the animation starts.

DurationType_Forever is deprecated. A duration of forever results in an animation that never advances from its starting value. If you want an animation to repeat continuously, use IXRTimeline::SetRepeatBehavior.
