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
The IXRStylusPoint structure represents a single point. All IXRStylusPoint objects contain properties that indicate the coordinates and the pressure of the point..
Note
You can determine the relevant PressureFactor only if the device supports it. Otherwise, PressureFactor has a default value of 0.5.
Multiple IXRStylusPoint objects make up an IXRStroke object. The IXRStroke object stores the stylus points in the StylusPoints property.
When you create a class instance, use an IXRStylusPointPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
You can also define an IXRStylusPoint 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 StylusPoint Structure on MSDN.
