Constants

 
RTSDI_AllData
Value: 0xffffffff
The plug-in receives notifications for all stylus data.
RTSDI_None
Value: 0
The plug-in receives no notifications for any stylus data.
RTSDI_Error
Value: 0x1
An error has been added to the input queue.
RTSDI_RealTimeStylusEnabled
Value: 0x2
The RealTimeStylus Class object has been enabled.
RTSDI_RealTimeStylusDisabled
Value: 0x4
The RealTimeStylus Class object has been disabled.
RTSDI_StylusNew
Value: 0x8
A RealTimeStylus Class object encounters a new Stylus object.
RTSDI_StylusInRange
Value: 0x10
The Stylus object is in range of the digitizer. Notifies the implementing plug-in that the stylus is entering the input area of the RealTimeStylus Class object or is entering the detection range of the digitizer above the input area of the RealTimeStylus Class object.
RTSDI_InAirPackets
Value: 0x20
The RealTimeStylus Class object is within range of, but not touching, the digitizer and is moving.
RTSDI_StylusOutOfRange
Value: 0x40
The RealTimeStylus Class object is out of range of the digitizer. Informs the implementing plug-in that the stylus is leaving the input area of the RealTimeStylus Class object or is leaving the detection range of the digitizer above the input area of the RealTimeStylus Class object.
RTSDI_StylusDown
Value: 0x80
The stylus is in contact with the digitizer.
RTSDI_Packets
Value: 0x100
The stylus is moving and is in contact with the digitizer.
RTSDI_StylusUp
Value: 0x200
The stylus has broken physical contact with the digitizer.
RTSDI_StylusButtonUp
Value: 0x400
A user has released a stylus button.
RTSDI_StylusButtonDown
Value: 0x800
A user has pressed a stylus button.
RTSDI_SystemEvents
Value: 0x1000
A system event has been detected.
RTSDI_TabletAdded
Value: 0x2000
A new tablet device has been detected by the system. Notifies the implementing plug-in when a Microsoft.Ink.Tablet object is added to the system.
RTSDI_TabletRemoved
Value: 0x4000
A tablet device has been removed from the system. Notifies the implementing plug-in when a Microsoft.Ink.Tablet object is removed from the system.
RTSDI_CustomStylusDataAdded
Value: 0x8000
A plug-in has added data to a queue. You can identify the kind of custom data by either the GUID or Type.
RTSDI_UpdateMapping
Value: 0x10000
A tablet mapping to the screen has been changed or set.
RTSDI_DefaultEvents
The plug-in receives the default stylus data.

Remarks

The RealTimeStylusDataInterest Enumeration values are used in a bitwise combination that defines the set of data notifications. Use the RealTimeStylusDataInterest Enumeration to specify only the events for which you would like to receive notification. Thus, improving performance.

The RealTimeStylus Class notifies plug-ins when it is retrieving packet data by calling into the respective plug-ins in a specified sequence. You control the sequence and types of plug-ins that receive these notifications. The packet data in the events can be modified by the plug-ins the RealTimeStylus Class object calls into.

You can control which methods are called on your plug-in by implementing the IStylusPlugin Interface:: IStylusPlugin::DataInterest Method method.

The following events are the default events:

  • RTSDI_RealTimeStylusEnabled
  • RTSDI_RealTimeStylusDisabled
  • RTSDI_StylusDown
  • RTSDI_Packets
  • RTSDI_StylusUp
  • RTSDI_SystemEvents
  • RTSDI_CustomStylusDataAdded
