Member Function Documentation

addListener()

void juce::TouchSurface::addListener

(

Listener *

)

Adds a listener to be called when the surface is touched.

Referenced by callListenersTouchChanged().

callListenersTouchChanged()

void juce::TouchSurface::callListenersTouchChanged ( const TouchSurface::Touch &  t )

inline

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

References addListener(), listeners, removeListener(), and juce::TouchSurface::Listener::touchChanged().

cancelAllActiveTouches()

virtual void juce::TouchSurface::cancelAllActiveTouches ( )

pure virtualnoexcept

Forces a touch-off message for all active touches.

getNumberOfKeywaves()

virtual int juce::TouchSurface::getNumberOfKeywaves ( ) const

pure virtual

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

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

removeListener()

void juce::TouchSurface::removeListener

(

Listener *

)

Removes a previously-registered listener.

Referenced by callListenersTouchChanged().
