interact with parent (or child) movieclips? 5. ? how to know which
button was clicked? 6. swf?why swf le can not get the right
response from the internet? 7. ?how to know if image les were
downloaded completly? 8. event 9. btn.onRelease = function() {
_root.hero_mc.gotoAndPlay(10);} 10. mc.onRelease = function()
{_parent._parent.mc.title_txt.text = "this is not good!";} 11.
loose coupling 12. listener 13. listenerfunctionlistener is just a
function 14. function click_handler(e:MouseEvent):void {
trace("hello, everyone!");} 15. register 16. addEventListener 17.
public function addEventListener(type:String,
listener:Function,useCapture:Boolean = false, priority:int =
0,useWeakReference:Boolean = false):void 18.
mc.addEventListener(MouseEvent.CLICK, click_handler); 19. event
name 20. public function addEventListener(type:String,
listener:Function,useCapture:Boolean = false, priority:int =
0,useWeakReference:Boolean = false):void 21. event name is actually
just plain string 22. trace(MouseEvent.CLICK);//
"click"trace(IOErrorEvent.IO_ERROR); // "ioError" 23.
mc.addEventListener(MouseEvent.CLICK, click_handler); 24.
mc.addEventListener("click", click_handler); 25. remove 26.
mc.removeEventListener(MouseEvent.CLICK, click_handler); 27.
remember to remove useless listener 28. save the world! 29. ow 30.
