Handle Events

Handle Events

• Use Q.EventManager to register events for stage.

var em = new Q.EventManager();
var events = Q.supportTouch ? ["touchstart", "touchmove", "touchend"] : ["mousedown", "mousemove", "mouseup"];
em.registerStage(stage, events);

• Write event handlers for the specific display object.

obj.addEventListener("touchend", function(e)
{
	//do something
});

In the event handler, you can obtain e.eventX, e.eventY, e.eventTarget, e.lastEventTarget for your specific use.

• Remove event listener.

//remove a specific handler by event type.
obj.removeEventListener("touchend", touchendHandler);

//remove all handlers by event type.
obj.removeEventListener("touchend");

• Unregister events from stage.

em.unregisterStage(stage, events);

• Aliases for some methods.

obj.on = obj.addEventListener
obj.un = obj.removeEventListener
obj.fire = obj.dispatchEvent
