IInkTablet objects work closely ink collector objects. An ink collector (InkCollector, InkOverlay, or InkPicture) can be set to one of two tablet-related modes:

  • All tablets mode
  • Single tablet integrated mode

The default mode is all tablets mode (set with the SetAllTabletsMode method of the ink collector). This mode integrates all tablet devices if multiple devices are attached to the Tablet PC. Because all of the tablets are integrated, available cursors can be used on any of the tablet devices, and each tablet maps to the entire screen. This allows automatic updating of the windows.

COM Implementation
