I'm currently working on a center stage component and I was wondering if there's a good way to detect when a stage component has been changed if any of the elements inside it have been enlarged?
This seems like it should be available but I can't find one that doesn't fire before the redraw. Or at all for that matter.
I'm having trouble removing the an event listener as well as the sprite at the same time. I currently get an error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
And if I comment out removeChild, I have no error but, obviously, the sprite remains on the screen. how I can rid myself of that error?
//Bullet extends Sprite Class
bullet:Bullet = new Bullet();
mc.addChild(bullet);

I have this problem: I have no idea how and where to add event listener to resize the menu. Here is main part of the code:
[Code]...
Taking my first steps coding in AS3. So I have my main class which extends sprite and I put new mc's on top of that. Using addEventListener on any child MC's with MouseEvent.CLICK works fine, but I can't add it to the main sprite. How can I register all clicks on the screen?

I've got a large bitmap (1920 x1306) that my client wants as a bg image, scaled to the swf size on load (930 x 575); but that can "grow" up to its original size if/when a user expands the browser window. All the rest of clips in the display list are to remain in place (except for a copyright clip, which they want to always be 14 pix above the bottom of the browser frame. I've tried loading the bitmap dynamically at full size and then using scaleX,scaleY to set it's initial smaller (930x575) size, and I've tried just setting the height/width of the dynamically loaded image using the math of scaleX,ScaleY just in case the scaleX "transformed" the bitmap so that it couldn't return to its original size. Both make the bitmap the right size. But the resize function below did nothing to it, (or the copyright.y.) THEN I tried just putting the bitmap into the display list (both sizing methods work here, too). But even as an original member of the compiled display list, the resize event is still not reaching the target. Everything I've seen on the web says this should work - but...no luck.
Here's the AS3 code in the 1st frame of my swf:
import flash.display.Stage;
import flash.display.StageAlign;
import flash.display.StageScaleMode;

I'm having a bit of a problem here. As per the title, my flash swf file works fine when tested from the IDE, but when I publish it and open it through the browser, the stage doesn't seem to resize along with the window.I post below a bare-bones example. The "back" movie clip should resize, only it remains at the starting dimensions
Code:

I'm having a little issue with the resize event and resize effect of a VBox.

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.
View 3 Replies am loading an image onto stage dynamically. When I click on the loaded image, i am drawing a circle/rectangle[which is of Sprite type] at exact pixel-position on the image and making these circles/rectangles(Sprite_objects) visible there itself. In this way, I am adding as many number of Sprites_objects, till I continue clicking on the same image present on the stage.
The code in my application(which displays red colored rectangles when you click on the image) is as follows:
If you copy the code into ur actionsPanel directly,then make sure "image1.jpg" file * is present beside the .fla file.Since it gets loaded iff it is present in same directory.
*/ var myContainer:MovieClip = new MovieClip(); var temp_x:int,temp_y:int; //Loading an image dynamically and adding listeners... var urlReq:URLRequest=new URLRequest("image1.jpg"); var loader:Loader = new Loader(); loader.load(urlReq);[code]....
It's never been an issue since I always anticipate it but just wondering...
if I put a MouseEvent listener on a movieclip/sprite...
Code:
whatever.addEventListener(MouseEvent.CLICK, clickAction, false, 0, true);
function clickAction(e:MouseEvent):void {
trace(e.target);
}
that traces a movieclip inside the intended target...
I have this snippet of ActionScript code that is supposed to resize an image to fit the sprite: (as in rescale the image not just clip it)

I'm making a resize function that has to resize a Project object that extends Sprite.
But I keep ketting a type coercion error:
TypeError: Error #1034: Type Coercion failed: cannot convert AS:: Project@318ff89 to mx.core.IUIComponent.
I've tried casting the Project object to an UIComponent or DisplayObject, but this also throws a TypeError.
[AS]var resizeTarget:UIComponent = new UIComponent();
resizeTarget = UIComponent(target.getChildAt(0));
var myResize:Resize = new Resize(resizeTarget);[/AS]
So basically should I try avoiding the use of Sprites in Flex?
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.
View 3 RepliesI'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.
View 1 RepliesThis 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:
[Code]..
how can i access event.target outside event listener method.say for example
my_mc.addEventListener(MouseEvent.CLICK, onC);
function onC(e:MouseEvent):void
{
var m:MovieClip = e.target as MovieClip;
}
trace(m.totalframes);/// not working
now what if i want to get totalframe property of m instance, in short for every movieClip clicked.
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.
I have a sprite in as3 code, I want to enter its height to resize it, how can I scale the width accordingly?
sprite.height = 200;
sprite.width = ??
How do you resize a sprite without resizing the contents? For example the script below create a sprite, attaches it to the root, creates a button, attaches the button to the new sprite then resizes the sprite. but it scales the button when I try to resize?[code]...

The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
I have a listener that calls a function which sets up everything on the stage exactly where and how I want it, works great. However..I also use the same function for my initial setup, and it's not triggered until/unless someone resizes the window, and as a result, everything is a mess until the window is resized.I could just duplicate the relevant bits in a separate function, but that seems needlessly redundant.Is there a way to trigger the function upon the initial load without waiting for a resize event?I would just call the function directly at the end of the script, but it expects a parameter that I can't figure out how to pass it.[code]
View 3 RepliesI got a very short question but I can't seem to find it on the internet (might be because I'm using the wrong terms). Is it possible to listen with a listener when a movieclip has been resized? I know there is a listener to do this with the Stage object. If this is not possible: do I have to make an interval that constantly checks if a movieclip is resized?
View 4 RepliesI am trying to set a listener so that I can respond to an flvComponent when it resizes etc. I am not uses any home made classes. I have stripped the code right down to this, and it still wont work! Have dragged a flvcomponent onto the stage and given it the instance name myVideo.
ActionScript Code:
stop();
myVideo.addEventListener(AutoLayoutEvent.AUTO_LAYOUT, fred);
function fred(e:AutoLayoutEvent){
trace ("hi from fred");
}
when I test I get "type was not found or is not a compile time constant:AutoLayoutEvent". I can do all sorts of processes like changing flv being played, moving it around etc.
how do I call the re-size action at the first frame? It works great once you resize, but isn't called at the beginning. I've tried a few things, but I'm shooting in the dark at this point.
Code:
sizeListener = new Object();
sizeListener.onResize = function() {
if((Stage.width > 1920) || (Stage.height >1200)){

I'll get into AS3.0 once I have time, don't want to rewrite a bunch of sites right now for something so small!
