HTML5 Canvas Mobile Touch Events Tutorial
To bind event handlers to shapes on a mobile device with KineticJS, we can use the on() method. The on() method requires an event type and a function to be executed when the event occurs. KineticJS supports touchstart, touchmove, touchend, tap, dbltap, dragstart, dragmove, and dragend mobile events.
Instructions: move your finger across the triangle to see touch coordinates and touch start and touch end the circle.
