virtual

Destructor.

Member Function Documentation

cancelAllActiveTouches()

virtual void TouchSurface::cancelAllActiveTouches ( )

pure virtualnoexcept

Forces a touch-off message for all active touches.

getNumberOfKeywaves()

virtual int TouchSurface::getNumberOfKeywaves ( ) const

For the on-screen seaboard view, this will return the number of keys.

For other types of touch-surface, it will return 0.

callListenersTouchChanged()

void TouchSurface::callListenersTouchChanged

(

const TouchSurface::Touch &

t

)

Testing feature: this allows you to inject touches onto a touch surface.
