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 an IXRPathFigure object to create composite shapes that contain IXRQuadraticBezierSegment objects and other segments.
The IXRQuadraticBezierSegment class does not contain a property for the starting point of the line. The starting point of the line is the endpoint of the previous segment or the StartPoint of the IXRPathFigure if no previous segment exists.
When you create a class instance, use an IXRQuadraticBezierSegmentPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
You can also define an IXRQuadraticBezierSegment object 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 element in the source XAML for your application, see the QuadraticBezierSegment Class on MSDN.
