KetaiGesture

public class KetaiGesture implements OnGestureListener, OnDoubleTapListener

Provides gesture recognition services to a processing sketch. To receive gesture events a sketch can define the following methods:

void onTap(float x, float y) - x, y location of the tap
void onDoubleTap(float x, float y) - x,y location of double tap
void onFlick(float x, float y, float px, float py, float v) - x,y where flick ended, px,py - where flick began, v - velocity of flick in pixels/sec
void onScroll(int x int y) - not currently used
void onLongPress(float x, float y) - x, y position of long press
void onPinch(float x, float y, float r) - x,y of center, r is the distance change
void onRotate(float x, float y, float a) - x, y of center, a is the angle change in radians
