ActionScript 3.0 :: Effective EventListener With Many Event Listener?
Jun 19, 2009
I'm new to AS3.0 Is there a good way to deal with many event listeners like say MouseEvent.MOUSE_OVER and MouseEvent.MOUSE_OUT for the same type of movie clips? I've been getting the following error if the mouse rolled over or out too fast.
TypeError: Error #1009: Cannot access a property or method of a null object reference. at csAS/onSubmenuRollOver()
TypeError: Error #1009: Cannot access a property or method of a null object reference. at csAS/onSubmenuRollOut()

I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.

if I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?

My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.

I'm moving on to my next massive programming project and I'm trying to decide whether I should code it in as 2.0 or 3.0. I came across the new click event model in 3.0. Right now it's looking like a pain in the butt to me. So now I have to make a function and add it as an event listener? what the hell? What's the benefit? I understand stuff like this makes AS a more complete language but it's kinda annoying.

This is a very basic question but I can't seem to find an answer. I have a mouse over event and have created the buttons with the mouse overs which is working great. I created the actionscript to go to a specific web page when a user clicks the button. Now, I need to add a label to the mouse over so when someone mouse's over any area of the button, it will show them a particular name for the button.
I am sure that this can be done using actionscript in a mouse event roll over command but I can't figure out what I need to show the text. Here is where I am:

I am doing this inside a module containing viewstacks and their childs.Calling onInit() on creationComplete of module.When I am inside one of the childs of a viewstack of this module and press Enter, it doesnt not invoke the listener function at all (bp inside this does not get hit).
private function onInit():void{
this.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
}[code]..........

This might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?
Such as:
myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...
[Code].....
And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.

I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....
It is only targeting the movie clip, not the buttons inside the movie clip.

When the escape key is released, I close the deepest child in a tree-like structure, and then tell it's parent (which is now the new 'deepest child') to close when the escape key is released ... but I do that while such an event is triggered, that causes the whole chain to close.

In my scrolling code I want to remove the eventListener for my reportStageMouse event, but I get an error: 1120: Access of undefined property reportStageMouse.

How can I access to an object who fires an eventListener event?
Let's say I have a mc:
var element = new MovieClip();
which has an eventlistener:
element.addEventListener(MouseEvent.CLICK, elementEventHandler);
[Code]....
So that is what I want to achieve... Recover the object who fired the event and then do crazy things with it (in this example, add another object in it).
pd: yes, I know I can directly use the var element in this snippet, but in the real code I'm generating the mcs in a loop, according to a xml file.

I have a MouseEvent.MOUSE_WHEEL eventlistener setup for a custom scrollbar component that allows the wheel to control the scrolling up or down.Inside the Flash dev environment when I test the flash app it works fine. However, when I test the app inside a web browser ( which has its own vertical scrollbar ) the mouse wheel controls both the scrollbar in my flash app and the scrollbar in the browser.Is there a way to setup the eventlistener on my scrollbar that it prevents the MOUSE_WHEEL event from bubbling up to the browser?

Lately i've been trying to right in external classfiles to create everything and make everything work instead of stuffing everything in my timeline. So now i have made a classfile that first creates all the movieclips i wan't on the stage and then defines what all the buttons do.
But when i want to acces a variable that has been created in "createMc" from a private function i get an error, so i have fixed this by giving the var's a name and then use getChildByName().
But i think this looks like a really innificiant way off writing something and was wondering if it was possible to write this in a better, shorter, and thus more effective way.
