Stroke [in]

The IInkStrokeDisp object that was started when the IInkCursor object caused the CursorDown event to fire.

Return value

Remarks

This event method is defined in the _IInkCollectorEvents, _IInkOverlayEvents, and _IInkPictureEvents. the _IInkCollectorEvents, _IInkOverlayEvents, and _IInkPictureEvents interfaces implements the IDispatch interface with an identifier of DISPID_ICECursorDown.
