RealTimeStylus Class

Handles the stylus packet data from a digitizer in real time. This class cannot be inherited.

Namespace:  Microsoft.StylusInput
Assembly:  Microsoft.Ink (in Microsoft.Ink.dll)

[UIPermissionAttribute(SecurityAction.Demand, Window = UIPermissionWindow.SafeTopLevelWindows)]
public sealed class RealTimeStylus : IDisposable, 

Use this class to provide access to the stylus events coming from the hardware. The RealTimeStylus class controls the flow of ink going to an ink collector.

Use this class to intercept the stylus packet stream. If you do not need to interact with the packet stream in real time before it gets to the ink collecting object, then use the InkCollector, the InkOverlay, or the InkPicture object instead of this class.


You cannot attach the RealTimeStylus object to a window or control in a different process.

Security noteSecurity Note:

If using under partial trust, this class and all its methods require UIPermissionWindow.SafeTopLevelWindows permission. For more information about partial trust, see Security and Trust.


The RealTimeStylus constructor will throw a Marshal.ThrowExceptionForHR exception if it is unable to create the underlying Win32 RealTimeStylus.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
