The event to be listened for.

Success.

Remarks

All ink collector events can be toggled by using this method. Most of these events are turned off by default for performance reasons. The only events that are on by default are Stroke, CursorInRange, and CursorOutOfRange.

Use the NewPackets, NewInAirPackets and CursorDown events carefully, in particular because they may have an adverse effect on ink performance if too much code is executed in the event handlers.
