ActionScript 3.0 :: Object Does Not Show On Screen Once Re-added To Display List?
Nov 3, 2011
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
[code].....

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

I've got MovieClips on the stage, both manually added, and added with code. I used this code to trace them all:
for(var i:int=0 ; i<stage.numChildren; i++) {
var myObject = stage.getChildAt(i);
trace(i);
trace(myObject);
}
All it returns is 0 and [object MainTimeline]. Is there something wrong with Flash, or did I do my coding wrong? The objects I put on the stage should be on the Display List, right?

I have an (empty) ArrayCollection that I wrap with a ListCollectionView. Then I add a series of items to the ArrayCollection, but these are not showing up in the view.
public var transactions : ArrayCollection = new ArrayCollection();
public var filteredTransactions : ListCollectionView = new ListCollectionView(transactions);
transactions contains 150 items, filteredTransactions contains none. I originally thought it was the filter I was applying, but even when I remove the filter, I still get no items in the filtered list.
Do I need to add the items to the view as well as the underlying collection (this would seem to defeat the purpose of using a view though...)?

I'm instantiating a group of RadioButton components into a Sprite and then later adding it to the display list. When the latter occurs, I can visibly see the font of the RadioButtons' labels changing from a serif to sansserif—but I have NO code to that effect anywhere. This occurs long after the components are actually instantiated, when they (via their parents) are added to the displaylist.
In Question_UI.answersContainer.answer:
answerUI = new RadioButton();
answerUI.group = rbg;
answerUI.label = text;
[Code]....
I've triple-checked the obvious, but there's NO code regarding the font of the label at all. It seems to only have to do with being added to the displaylist.

The site operates around a swf named main.swf. All the different content areas are external swfs called by a navbar in main.swf. One of the primary content areas is a gallery of our work, with five separate types; branding, package design, collateral, Internet, and Digital. The left hand swf for the Gallery section contains five movie clips that let you select the specific gallery area that displays on the right hand side. Included in the right hand area are thumbnails (movie clips) that when clicked she wants a Greybox-like slide show to appear over the entire area (1100x x 690), INCLUDING the main.swf. As I currently envision it, this is an 1100 x 690 XML-driven portfolio swf, with the alpha of the overall stage box at about 30%, and the actual gallery centered.
If I haven't lost you, my challenge is to call the slide show swf from a click event in the thumbnail on the right hand side. If I understand the Display Object Model this swf is about three levels removed from the stage.
How do I call the slide show swf that must be added ABOVE the main swf in the Display List from a click on the right hand area thumbnail?
I'm gaining a better understanding of classes, and am using them to hold all the AS for the external swfs. Basically I need to be able to talk to the main swf from the brandRight.swf which is the right hand swf containing the thumbnails.

It'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:
[code]...
there should now only be one "myDisplayObject" on the stage.

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?

I 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?

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.

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.

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.
stop();
import flash.display.MovieClip;
var i:int = 0;
var a:Number = 10;
var ageString:String;
var ageText:Array = new Array();

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...

I 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'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.

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?
