When I'm removing an object from the display list (via removeChild), I'm performing a splice on all of the arrays that the object has:
[Code]....
My thinking was that this frees up some memory similar to disposing a bitmapdata. Does this even do anything? Or, will arrays be cleared and the memory usage restored when the object is removeChilded?
I have an application that uses a main class to control other MovieClips, adding and removing them as needed, most of them are separate screens or sub menus.
When I leave the main menu and come back to it later from another screen, certain animations and roll over buttons still play, which I don't want, I basically need the main menu screen to reset every time it is seen.
I read up on this and found out that removing the child doesn't necessarily remove it from the memory.
I tried setting the mainmenu to null before moving onto a different screen but this threw up an error, stating that the parameter child must be none null.
how to completely kill my mainmenu when it is not needed.
public function confSubMenuOneScreen():void {
subMenuOneScreen = new SubMenuOne();
mainmenu = null;
[Code].....
This is the example of code that removes the menu and adds another screen, with the mainmenu = null code that throws up the error.
How do I removeChild only if it's in the Display List?One button on my stage will addChild(radioButton) and another removes it. If the remove button is clicked first, then it obviously tries to remove something that has not yet been added and an error is returned. I've tried using the DisplayObjectContainer class with the contains() method to no avail.
View 12 RepliesI was going through the options the generic Vector class offers to delete and/or insert items from/to an array, and it seems to me that the only way is by using the Splice method. For me, this method does a lot of work I dont utilize in my code (like creating a new array as a result etc.), hence
is there an optimized way how to delete a certain item from a vector, instead of calling myVector.splice(idItemToRemove,1) ?
why I cant kill a child in my display list. So I'm working on an ad that is going to load in different swfs depending on the link you click. What I wanted to happen is when the ad loads the first swf is auto loaded in to my container. Then when you click on the next link the new swf would cancel out the last one. What I am getting is an overlap of the swfs and I understand that. I can't figure out how to kill the other children. I tried unload and remove child but have been unsuccessful.

If you're removing a MovieClip from the display list, and that MovieClip in turn has child MovieClips which have their own event listeners, is it necessary to remove ALL listeners from the child MovieClips? or just the parent MovieClip that is being directly removed from the display list?
View 2 RepliesI've asked this question before but had no answers... so here I go again I have a structure of objects: Top object A has as children (addChild children that is...) one or more objects B_1 to B_n. The B_n may in turn have one (1) associated object A' (Same type as top object, not displayed to begin with). When I click a B_n two things may happen:
1. If it has as associated object a A', put it on the stage (as child to B_n).
2. Otherwise it is a leaf and it does other things.
If '2' happens I want to collapse the tree, that is remove the top and all children of same type from being displayed. I thought a recursive approach should work:

Is there any way to test if a display object has been added to the display list?
View 9 RepliesWhat's a simple way to detect if a display object is currently on the display list?
View 1 RepliesIt's my understanding that a display object cannot be in the display list more that once.So if I add something to the stage shouldn't a second addition of the same object replace the first? for instance:

there should now only be one "myDisplayObject" on the stage.
To remove a dynamic displayObject completely you need removeChild or removeChildAt(index) remove all the refrences to the displayObject nulling the displayObject
But this is my case
PHP Code:
//here recto is a MovieClip on stage//i creat a dynamic display Object named newMcvar newMc:MovieClip =new MovieClip();newMc.graphics.beginFill(0x000000,1);newMc.graphics.drawRect(0,0,10,10);newMc.graphics.endFill();recto.addChildAt(newMc,1);//i refrence the newMc using
[Code].....
I believe that it is refrencing newMc but I am not sure why nulling refrenceMc has effect on newMc

Im attempting to create a class which cleans all the mess it's done by itself. If i make some instances of this class in an external class, i want the base class remove itself, or in other words, if i linkage this class to any movieclip, i want to remove this movieclip not in the file I created it in, but rather would like it to automatically remove itself if i want it to. I don't know if it's even possible. A simple removeChild(this) isnt working.

I have been scripting this flash profile card which pulls data from multiple XML files. The problem i am having is when it comes down to pulling this 1 set of information which is accessing the attributes of an array of specific XML nodes on display after the first item it inputs a comma before each item.
My code:
---------------------------------------------------------------------- ---
xmlData = new XML ();xmlData.ignoreWhite = true;xmlData.onLoad = loadXML;xmlData.load ("../xml profiles/test.xml");
---------------------------------------------------------------------- ----
function loadXML (loaded){if (loaded){ xmlNode = this.firstChild;
[code].....
This is just a draft version of the layout i used to pull up fake data... to show the commas.Lastly i am wondering if it is possible to control the 3 text fields using 1 scroll bar or would i be better off learning how to create columns in 1 text field to display these lists.
I've made a little movie that reads items from an XML document and when you click on a thumbnail it adds the details and the price to a list and totals the amount. The problem I'm having is when you want to remove an item; I want to make it so that the items all shift up and there isn't a gap in there but at the moment they're overlapping sometimes when you remove something from the middle of the list.I'm not really sure where the problem lies because I've been staring at this for a few days now nothing's coming to me. It's probably in the below area, I think it's going haywire when the array gets remade but the num property of the remove button doesn't get updated.[code]I've attached all of the relevant files if anyone wants to take a look at it in action. Also, I know some of the code might seem a bit strange (like reading the XML in a loop and then pushing that into a different array) but there is a reason for it, I've stripped that part of the application out though.

Is there a way to make a display object always be at the top of the display list?For example, I know you can set the childIndex, i.e:setChildIndex(myDisplayObject, numChildren-1);But is there a way that an object has sensed that something else has been added to the display list and restack themselves accordingly?
View 2 RepliesI have written this little script, as i want to remove some of the text fields that are currently contained within the Display Objec, however it does not like to see the TextField as a varaible name. How would i convert the object from an array to become a textfield that can be removed, after being added through
addChild()
This is the script
var delayHeading:Number = 1500;var repeatHeading:int = 1;var setShow:Timer = new Timer(delayHeading, repeatHeading);setShow.start();setShow.addEventListener(TimerEvent.TIMER_COMPLETE, maybeLater);

When a movie clip is removed from the stage it's properties are still accessible including visible == true. How do I test to see if it is off the time line?
View 9 RepliesI have an object that controls another object that is on the display list.
The setup looks like this:
Parent (Main Timeline)
- Child
-- Grandchild --> contains instance of behaviour class that controls the grandchild's movement
I have an event in the "behaviour" that I'd like to reach the parent, but the behavior does not extend Sprite or MovieClip.
How can I get this event to reach the parent?
Any command to check whether an object is currently present in the Display List? I have a TextField called _startHereText. I have some logic where I need to sometimes use RemoveChild to take this object out of the Display List, but I first need to determine if it is presently there.
View 9 RepliesFor 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.

I'm trying to dispatch a custom event from a custom class (which implements IEventDispatcher) to another custom class (also implements IEventDispatcher) but I cannot trigger the corresponding event handlers.The classes are instantiated at different parts of the application: one on the main canvas and the other on the back-end (data side) of the app. Neither of these is part of the display list hierarchy and I need them to communicate through events.I've looked through adobe docs, the web and Mook's Essential AS3, but have come up with nothing...
View 4 RepliesI need to access a non-display list top-level (Parent? Ancestor? What's the correct term?) object from a display list object, and I don't know how.
In my code, ResultX is an instance of my custom class Result. Card is a sprite, a visual representation of the ResultX object, defined inside the Result class and attached (or removed) to the stage via a separate function inside the result class as needed.
I want to refer to the correct Result object when the user clicks on the corresponding card to call a function there. In accessing the sprite manually, ResultX.card works fine, but I don't know how to go upwards trough the path - card.parent (or actually target.parent, since it's done via event) just returns Main, of course.
I'm trying to create an image class that I can reuse throughout a website I'm making.
When you click an image i want it to expand to fill the screen. When this happens obviously it will have to be at the top of the display list so that none of the other objects on the website are above it. The problem is that I want to be able to use this class throughout the website, even within containers that are beneath other objects so it seems impossible to simply bring it to the front easily?
Edit: Maybe when you click an image it would create a replica on top of the current image but above all the other objects on the main stage - then expand that one instead of the original image in the container? Theres got to be a better method though... I can't imagine this working too smoothly.
I have an object that is instantiated, then placed into a property within a singleton (single instance) object. When a button is clicked an event is dispatched carrying a payload that references the display object that is held within the Singleton. When the event is heard, my view object adds the object to the display list e.g. addChild().The Item shows. Now If I hit another button an event is dispatched, and a new item is added to the display list via the method above and is seen. The 1st object is removed from the display list Here is my problem. When I click the button to load the 1st Object the above process is executed again but the object does not show.
I can run trace statements from the object that is supposed to be visible and they run fine. I even do a check to see if the visible property is set to true, and it is, but not object is on my screen. Code for this process.
//custom event carries the name of the page aka display object. this is a string
dispatchEvent(new MenuEvent(MenuEvent.CHANGE_VIEW_STATE, event.payload));
//When the event is heard, the following condinial is run

I've got these Flash students I TA for a course, and they are doing drag and drop exercises and have come across some weirdness.(They are using a frames based design to represent different pages of activity, with a menu to goto each frame under user control.)At author time:
1. they set up drag and drop as3 for an object on a particular frame.
2. when startDrag is initiated, they moved the dragged object to the top of the display list, so it appears to float above all other objects as the user drags.
at runtime,a problem appears:the object seems to have been pulled out of the frame, and now floats in a display list above any frame that may be advanced to.What's going on here? It's like the object got pulled off the authortime stage and now is disconnected. Going back to the drag and drop frame shows the original object again, reinstanced, along with this copy that got pulled out.
If an asset (say an swf) is already loaded. Does it increase memory use to add and object to the display list?
