I would like to know the internals of that method, in other words what exactly happens when I call that method. If someone can explian it with a list 1,2,3... would be great. including events..
and the addElement method too, if is possible.
I have a component ObjectHolder which extends UIComponent that holds many children UIComponents. However, after using addChild() to add these children to ObjectHolder, its width and height remain zero. Is it possible for the UIComponent to automatically expand to the size of its containing children components?
public class ObjectHolder extends UIComponent
{
public function ObjectHolder()

somewhat understood the basics of adding and removing children, however, I am facing another problem. After using the removeChild Function, I can't seem to add another child.For example:
ActionScript Code:
var attachedMC = new (getDefinitionByName("Content1") as Class)()
Page.addChild(attachedMC);
[code].....
Is there method that gets called just before object destroyed? So I can override it.
Like
protected override function beforeDestuction():void
{
trace("This object is about to be destroyed!");
}
I wonder is anyone can look at this code and tell me why calling the removeSelectedChild works when called from the same document, but returns the following error when called from the child document/component.
"ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller."

I'm trying to have a class file which can add objects to the stage via addChild; however, when I call addChild from within the class file, I get the error "1180: Call to a possibly undefined method addChild." I've tried importing flash.display.* and that doesn't fix the problem. Does the class file have to extend Sprite or MovieClip to be able to add objects to the stage?
View 8 RepliesI have downloaded Box2d ([URL]) and created a project that looks like this: [URL]. catalyst is the green cube and it has the base class "shapes.box", it is inside "world" which has the base class "wck.World". What i want to do is to add another "catalyst" from the library inside "world" when i click on add_btn. I tried to accomplish this by this code:

I create a few squared sprites and then remove the first one and display the coords.[code] The x coordinate is still 0, though width has changed,getBounds shows correct values.I would expect x to change as well.Because of the wrong value of x, globalToLocal and localToGlobal work incorrectly.If you click somewhere on the left side of the second (still visible) rectangle you get: 2 28 (x=2, y=28)which is good for nothing. The values in brackets should be in stage coords and they are not.[code]
View 1 RepliesI have a container with children that needs to be replaced by other periodically. Those children are sprites and they have one weak referenced event listeners for MOUSE_DOWN event.When I call removeChild on children, numChildren from container decreases to 0 but they are still visible in flash. I even tried to remove container and recreate new one but it still doesn't work. Also tried to add some dummy simple sprite instead, without any event listeners but it didn't bring any results. I presume that garbage collector is not working as I wish :)Here is my code for creating sprites:
itemHolder=new Sprite();
addChild(itemHolder);
itemHolder.y=itemHolderY;

For example, I have a function that is triggered by a button click This function loads an external swf.I then set a global variable swfLoaded to true, with the idea of having an if condition that executes removeChild(loader) if swfLoaded is true.When trying to execute removeChild(loader), I get an error telling me that it must be the child of the caller.I've seen the code below, which loads a default swf, but I don't want a default swf - I just want one loaded if the button is clicked, and then if another button is clicked, the original one to be removed before the next swf is loaded.How do I make this code work without loading a default swf, just loading one once someone clicks a button, and then removing it?
var Xpos:Number = 110;var Ypos:Number = 180;var swf:MovieClip;var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest("swfs/eyesClosed.swf");

I have a MC that the mouse can drag and slide, when it gets removed from the stage when it hits an out of bounds object. I re add it to the stage at the x,y position it originally started from but when I re add it it continues to slide in the direction it was going before it was removed.

I'm making an application for the iPad that allows me to swipe movieClips that are 1024 x 768.The application starts with movieClip1, movieClip2 and movieClip3 added to the stage.When you swipe to the left... they are to move to the left. When a movieClip is off the stage to the left... I want to removeChild and then addChild the next one in the queue to the right of the visible clip. This will provide a seamless swiping experience.

I first noticed it when this function started throwing a 1009 error:
[Code]...
were throwing the 1009 error. Which is wierd on two accounts. First, if I remember right, error 1009 comes about when referering to an object that is not on the stage. Which makes NO sence when getting it from an addChild! Second, this error only starts to occur the second time I use the function.

I am putting together my file right now which is now using visual elements purely added and removed via AS3 (addChild / removeChild) methods.My question is just about the proper time / place to declare their variables.Can I declare them all at the start of the movie (frame 1) and just call them when I need them, or is it better to declare them on the frames that they are introduced on? I guess the question is really, will I ever lose those variables throughout the movie once they are declared?

This is my code to addChild and removeChild when clicking a button. And i know there is a way to make this more dynamicly instead of hardcoding it.
ActionScript Code:
// Yatzi-knapp
yatzibtn.buttonMode=true;
yatzibtn.addEventListener(MouseEvent.CLICK, onClick);
[Code].....
as you guys can see it addChild with dynamics and its not hardcoded. difference between adding a movieclip from the library and loading a swf external?
because i cant get this to work. Even tho my code does addChild and removeChild i get error-messages in the output. The movie works fine but it isin't a pretty code

I am doing a project in which I need to open and close MovieClips. I have my Scene1 which loads the first MC (named "page1") then page1 plays and I would like it to unload itself and load the MC named "Page2" and so on up to page 10 ...
On the last frame of the MC "page1" I have this code:
stop();
stage.addEventListener(MouseEvent.CLICK, animate2);
function animate2 (event:MouseEvent):void {
stage.removeChild(stage.getChildByName("clip1"));
var clip2:MovieClip = new page2();
addChild (clip2);
}
But all I get is this error message:
TypeError: Error #2007: Parameter child must be non-null.

I have two classes, Init (which is my Document class) and LoadXML which... er.. loads in some XML data.
Init calls the LoadXML and when it has completed a green backdrop is draw to the screen...
but...
Why do I need to put addChild in both classes before the green backdrop (a simple rectangle) will show up.
Init.as
Code:
package{
import flash.display.Sprite;
import flash.display.Stage;
[Code].....
the confusing thing is why I need the addChild twice, once in each class - otherwise the green box doesn't show, no matter which one I take it out of?
And if its twice is that two green boxes on top of each other being added to the stage? one at depth 0 and one at depth 1?
I'm in the right place for this plea from yet another novice trying to learn AS3 in Flash with a couple of very good books but no one to talk to about it - and in danger of losing hair in the process.
My problem: I have a web site containing 8 pages. Each page is a separate movie clip, and each is in a Labeled frame. My intention is to have an overlay for each of the buttons in the top left panel of the home page. On the positive side I have managed to achieve the dynamic placement of an instance of a library movie clip called "sampleAR" via addChild to overlay on top of my home page. But I can't for the life of me get removeChild to rid me of the wretched thing again. My home page is in frame 1 of the movie labeled "Home". This contains a movie clip with the instance name "HomePage" on the stage. Inside the "HomePage" movie clip is my script sitting at the end where the movie stops in frame 44.
The code sits here because this is the only place I've managed to get any kind of result with the following code:

how to add an image under another one called with addChild?
View 1 RepliesHere's some code I created as an answer to another question. It pulls a library item out of the library and puts it on stage programmatically. No big deal, except that in order to get the image displayed on the screen to actually update, I had to removeChild() and then addChild() it back. Is there another way to force the screen to redraw?
[Code]....
Note that in this example, this code is on frame 1 of the timeline. It _feels_ like imageClip is not a direct reference to the thing that's actually on the display list. However, when I modified my code to replace the reference to the AS variable imageClip with a more direct reference to the element on the stage (imageClip = getChildAt(1)), that made no difference either.

I'm trying to make a basic mouesover and mouseout that will display a help/key box on the screen. I created the help box that will be displayed as a symbol called helpbox. I updated the linkage to export to Actionscript and called the class Helpme. The object I'm using to instantiate the Helpme class is a small graphic called helpcoast. I want the "helpbox" in the new class "Helpme" to be displayed only when the mouse is over the helpcoast graphic. When I test the movie and mouse over and mouse out of the graphic once, I get no errors, but if I mouse over it, then off it, then back over again, I get this error in the output box:
