Method Summary

Modifier and Type	Method and Description
void	penButtonEvent(PButtonEvent ev)
void	penKindEvent(PKindEvent ev)
void	penLevelEvent(PLevelEvent ev)
void	penScrollEvent(PScrollEvent ev)
void	penTock(long availableMillis) Useful to detect if the listeners are taking too much time processing events (availableMillis<0) causing pen lagging (pen events being queued at a higher rate than they are being processed).

Method Detail

penKindEvent

void penKindEvent(PKindEvent ev)

penLevelEvent

void penLevelEvent(PLevelEvent ev)

penButtonEvent

void penButtonEvent(PButtonEvent ev)

penScrollEvent

void penScrollEvent(PScrollEvent ev)

penTock

void penTock(long availableMillis)

Useful to detect if the listeners are taking too much time processing events (availableMillis<0) causing pen lagging (pen events being queued at a higher rate than they are being processed).

The pen fires queued events at a given frequency (by default Pen.DEFAULT_FREQUENCY) in its own thread. Each cycle, after firing and processing the events, the pen calls jpen.event.PenListener.penTock(long availableMillis), where availableMillis is the time left of the period: availableMillis=period-firingTime , period=1000/frequency, and firingTime is the time spent in firing and processing events in the cycle.

This method is called from the event dispatch thread if Pen.getFirePenTockOnSwing() is true.
