How do I remove all children from a display object container? I want to make sure that when I re-enter a particular frame that there are no imageLoaders loaded into my photoGallery.
View 2 RepliesIn my experiment memory usage keeps growing a little (more, and more RAM usage after GC) when I use repeatedly:
Code:
removeChild(picContainer);
addChild(picContainer);

Well I'm starting to really enjoy AS3, my next question then is this: In AS2 I'd often remove all movieclips with something like this:
PHP Code:
for(var i: String in container) {
container[i].removeMovieClip();
}
Is there something similar in AS3 that I can do without resorting to maintaining an array of references to each child of my container?
I can't come up with a function that will collect the names of the children in a object container and put them in a array.
View 4 Repliescan I resize a display object (container) without its contents (children) are resized?
For example, in the following code when I resize the green square, red is also resized. I wanted to resize only the green.
ActionScript Code:
import flash.display.Sprite;
var sprite:Sprite = new Sprite();
sprite.graphics.beginFill(0xff0000);

I want to destroy/remove all the children of an object including grandchildren of those children and so on.
I was thinking of using a recursive loop along the lines "if you have children, check if they have children, if they do, check if THEY have children and so on until they have no children and if so removeChildAt(0) of the parent you last checked.
ActionScript Code:
obj0
|-obj1
|-obj2

A quick second question, we all know that event listeners should be removed when no longer needed but I was wondering about the event.COMPLETE listener for loading say XML or a video file or any loader object. Is there any point removing that listener of is it in effect dead anyway because it has triggered when "COMPLETE" and won't ever trigger again? Isn't it still "listening"?
I am having problems accessing sub-children of my displayObject. Here is my code:private [code]but it's not working.
View 1 RepliesI have a custom class extending MovieClip, and in my code I add a few children to this custom class.When I add my mouse over event listener, it works, but it fires every time the mouse rolls over any of the children too!I only want it to fire once when the display object as a whole is rolled over.
View 1 RepliesIs there a simple way to completely empty a display object container regardless of what it contains, including if it's already empty? In other words, without determining its children and using removeChild on each?
View 2 RepliesIs it possible to get dynamically created children of a display object instance in action script 3?
Example
trace(_view.getChildByName("name")) = returns name of display object (success)

For some reason below is not working. It is probably very obvious but I am not seeing it. As soon as I comment out the container mc variable and just add Child to root timeline I see everything which means me container is not being added to the stage correctly.

var i:int = 0;
var a:Number = 10;

lets say i have 2 classes in the same package.and i add the same event listener to each of them, for example i add event.resize to some display object container in both of them.how can i prevent the code attached to that listener to execute in one of the classes if that event happens?

View 2 RepliesWould it be possible (Without being extremely inefficient) to loop through a display object and reset their children's ChildIndex based on their y value?
View 1 RepliesThis has to be simple, if only I knew how. I'm an AS3 newbie, and am having difficulty setting up multiple specific EventListeners within a code generated display object container.
I am generating a 'page' (Sprite) with a heap of 'cards' (Sprites) on it. Each of those cards, in turn, contains a selection of text boxes and other objects generated from database output using a 'for' loop. My hope is to attach an EventListener to each 'card' so that a MouseEvent will let me manipulate the data that lead to the content of that actual card (the i-th iteration of my for loop). I've been playing with everything I can think of (limited repertoire of thoughts though) and the best I've managed is for my EventListener to access the final set of data, whichever 'card' I click on. I've summarised and attached my code for the function, how to get back to the i-set of data from the EventListener attached to the i-th card. I can handle the PHP and MySQL side of things but am fumbling my way into the OOP of AS3.
I'm currently working on a custom component which extends Canvas (let's call it SuperCanvas) ; it's basically a container that let you zoom & pan its contents. It would be too long to explain why, but I can't use scrollRect, so I was forced to declare a Canvas object (called innerCanvas)... inside my SuperCanvas (I know, not very nice =/) I would like to know if there's a proper way to "redirect" the creation of my component's children in this canvas.

I have been getting this error after a bunch of different ways of trying this. I am attempting to create a new instance of my movieclip which displays external images via xml. I want a new instance of the movieclip every other frame and need to be able to remove each instance on every other frame. It will work going forwards, with a remove child call but as soon as I go back a frame, the error pops up.
how do we remove object( sprite which has an external swf as it's child ) from display and more importantly from memory yet we still can use the same variable to add another object (yes another sprite like the one we removed yet has different content).., "
i did tried the removeChildAt thing it did remove all the child from the display list but i still can hear sound from video running.
here is small scale code of what i'm doing (sorry that i can only give you chunk code of loading and adding)
// var SWFList:XMLList; //used to hold a list of all external swf source,atribute and etc// var totalSWF:int; //hold the total number of external swf there is to be loaded
// var swfLoader:Loader; //instance of loader class used to load the external swf

Just wondered if I remove a parent movieclip and then set it to null, will it remove all the child movieclips within it from the Display list and also from memory, or do I need to iterate through the parent movieclip removing all its children before removing the parent?
View 8 RepliesI have a little trouble in managing the children my container. The fact is that it has a lot of children and their y coordinates are very random.
Is there anyway i can order them by y coordinates that the lower will be in the front and the higher with be in the back?
is it something that that I can do with 2 "for"?

I am having trouble determining where to add my removeChild() statement to clear multiple movieClips from a container mc. I know I need to determine if the container movieclip contains anything. I don't know how or what I should put and where to put it. If I can determine if my container mc has movies in it, I am assuming I can just declare it again (i.e
PHP Code:
panel= new MovieClip();
)to clear it. Am I correct?

I'm using as container for my LinkButtons. I would like to know
1) How can I remove the space between the items in my Tile container.
2) How can I set dynamic width for my items (at the moment they all have the same width regardless the width of the included component)
3) How can I avoid to display scrollbars if the items are not included in the container
If I have a container, and I set clipContent to true, how do I get the total height of the children inside it? Is there a method for doing this without itinerating through every child and summing the heights?
View 1 RepliesAt one point in my script I'd like to check a MC for the number of children and limit this number to 3. For that I use this script:
Code:
if (container.numChildren > 3){
for (i = container.numChildren; i > 3; i--){
container.removeChild(container.getChildAt(i-1));
popError('Horizontal nur 3 Elemente!');
}
}
This somehow works fine if there are 4 or 5 children in the MovieClip, but as soon as there are 6 or more, it throws an Argument Error #2025 and does not remove anything. BTW it does not make difference if I use container.removeChildAt(i-1);
i'm getting the #1010 error... code below:
Code:
var curProject:int = 0;
var curExample:int = 0;
var container:MovieClip = new MovieClip();
im.addChild(container);

I'm using an accordion container that has it's creation policy set to auto. One of the accordion's children is a spark border container that has a data grid within it. Currently, I'm using the data grid's creationComplete property to call a function; similarly, I'm using the dragComplete property to call another function.
How can I add listeners for events (creationComplete & dragComplete) via actionscript? The obvious problem is that the accordion does not create all its children on creation (nor do I want it to), so I can't simply use something like: datagrid.addEventListener(...)
I have a VBox inside a Canvas. The 'red bars' are custom components based on 'Canvas'. All red bars are of equal height. I have 20 red bars inside the VBox. The scrollbars visible in the screenshot are the Canvas's scrollbars. The scrollbars of the VBox are disabled using verticalScrollPolicy = off.
Without scrolling, only 16 red bars (and a part of the 17th bar) are visible. However, when I scroll down the Canvas I expect to see the remaining red bars - but the bars that are not visible when the application starts don't get 'drawn'. What am I doing wrong? I want the user to be able to see the 17th - 20th bars when the Canvas is scrolled down.
is it possible to retrieve all children of a certain type from a parent in actionscript 3? i only see getChildAt,getChildByName, is there a getchild of a certain type like get all childs of object type:Food?
