I tried a simple example for createjs, yet, the onMouseUp event is not fired, what would be the reason?
Here is the example I tried
I am not 100% sure, but I don't know if that syntax will work:
_stage.onMouseUp = stageClickHandler;
I always prefer to add an event listener in Haxe:
_stage.addEventListener(MouseEvent.MOUSE_UP, stageMouseUpHandler);
