Flash :: Determine The Display Object Hierarchy An Event Will Capture/bubble Through?
Jun 7, 2011
In Actionscript 3 is there any way to determine the precise display object hierarchy an event will traverse through when dispatched from a given object? The object is not necessarily a display object.Although I could imagine this actually being useful somehow, in my particular case it is a learning exercise. I'm trying to master the event system in flash and have some locations where I'm very curious what path an event will take when I dispatch it.

[code]I added MouseEvent.MOUSE_OVER event listener to the 'back' sprite, but it doesn't get called, because the 'text' element is in front of it.I want to keep the event firing only when mouse is over the 'back', so I can't add eventlistener to the 'btn'.I could put some transparenet duplicate of 'back' in front of the 'text' and add listener there, but I believe there should be a more elegant solution.Maybe there is some way to exclude an element from the whole capture/bubble event procedure?

I have two components being absolutely positioned within a container (they are MapSymbols on an ILOG Elixir map, if that helps). Each component is a VBox with an Image and a Label. Images have functionality tied to the Click event; labels do not.
The problem is when 2 items are positioned so that the label of one is above the icon of another in the z-index, so that the label eats any mouseOver and mouseDown events. Bubbling doesn't help since it bubbles from the label to the vbox to the container, never hitting the lower element. I can't set the vbox to mouseChildren="false", since that keeps the image from getting clicked, as well.[code]...

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.

I am trying to Scale the bubbles within the bubble chart. The problem is, I have no control over the data coming in, and the radiusField values are usually below 0 ( no negative values ) with a max of maybe 2.
I created an ItemRenderer for the BubbleSeries, and tried adding a scaleX and scaleY value on the createChildren method, but nothing happens.

I want to have the parent of my class handle the event first, then I want to have the child handle the event. Is there a way to explicitly bubble the event up? I want to do something like this:
...
this.addEventListener(MouseEvent.CLICK, characterClicked);
...
private function characterClicked(e:Event):void{
// pass event to parent to be handled first
...
}
Is this possible, and if so how?

I have a class called Bike.as, linked to a movieClip in the library. The class essentially tweens a bike graphic across the stage. At the end of the tween, I instantiate a new class called Slideshow. Slideshow loads an image. The image loads(I get no loading error, and I can trace info about the loaded content)... I just can't seem to see it. In attempting to debug, I wrote the loading code(in Slideshow) into the Bike.as file(replaced the code that instantiates Slideshow), and it worked. Did it work because Bike is linked to a movieclip, and Slideshow is not(Slideshow is called in Bike.as)? I'm attempting to transition from AS2 to AS3. Here's my Slideshow class:
public class Slideshow extends Sprite {
private var container:Sprite;
private var loader:Loader;

I've created some classes for a nav menu and I'm having some trouble dealing with the click. The bottom class of the chain gets the click, but I need to pass that event up a hierarchy of classes to the very top so it can get handled.My hierarchy looks something like this:
AllMenus
- MenuBar
- - MenuItem

I need to capture the event raised when a flash video ends. If possible, I'd like to distinguish this from a user clicking the stop button.
One thing to be made perfectly clear:
I DON'T HAVE CONTROL OVER THE PRESENTATIONS OR THE SWF FILES.
What I'm looking for is simple (I thought) js automation of the client player object, not more complex interactivity with the presentation itself. I thought this would be really simple stuff, but a dozen Google and Bing searches later, I can't find anything about it.

I'm trying to capture the redraw event for some MovieClip / Sprite objects that are in a Scroll area.Ideally, should be able to capture the event when Flash Player itself redraws the objects as can be seen with "Show Redraw Regions" in FP Debug.I've tried to use the Event.RENDER to capture this, but it even fires when the object is not visible / redrawn.

I know the difference between the two, but I never felt the need to use the bubbling feature. If I want to listen to an event from a deeply nested children, I always use the capture phase. Could someone explain to me why I should rather use bubbling, its advantages, and maybe show me a situation in which bubbling would be the only solution?

Does flash.display.Loader determine the file by filename or header?
The reason why I ask is that I'm getting an IOError: "Unknown File Type" when loading an swf which has a strange filename (in the form of "filename.randomnumbersandletters.swf").

I m building a little application, im design the graphic in Flash and im using Flash Builder for the Programming Side. I have 5 MovieClip inside a Sprite (the container), and i want to listen for MOUSE.CLICK. I add the event listener to the Sprite, instead of one for MovieClip, and its working good like this.
What if inside the Sprite (the container) i have also a TextField and exclude it from the event flow?

I have a utility class that I use to load images that never gets added to the stage and is extending EventDispatcher, it simply loads the data and spits it back out on request.
I want to add a custom event to track loading progress from outside the class. The events are firing but not (i think) bubbling because they aren't in the display list.
Is there a good way around this? I was thinking: Can I have a non display list object tell a display object to send the custom event for it?

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 have a SendData class that sends form info to a php script. It is a static class that does not extend anything.
I want to be able to dispatch an event if there is an error, or when it gets info back from the server. I have a custom event class that I have been using to dispatch events like this, but I have only used that in displayObject extended classes.
The problem is, it seems like something has to be a displayObject based class to dispatch events. I know there must be a way to do this, but I'm having trouble finding it in searches.

I don't understand the "heirarchy" of Flash Output Error Messages. For example: TypeError: Error #1009: Cannot access a property or method of a null object reference.
[Code]...
This error shows when I preview a SWF that calls en external swf. All the code listed in the Error Codes is contained in the external swf. In the TypeError -- where do I look for the problem code? bBrand_Gallery is a class description for the externally called swf. The externally called swf runs fine by itself. All functions in the package are declared as public functions. I know that the null object reference means that it's looking for the property of an object that is not yet instantiated. How do I find that object? Would it most likely be a variable that is not delacred publicly?
I believe the ArgumentError has to do with the fact that the DisplayObject in question is not "created" by the function startShow which includes the removeChild statement. How do I resolve that issue?? Is there a reference as to the best way to interpret these error messages?

i have a question while reading Flex 4 Cookbook i came across the method to dynamically adding control to the container controls but nowhere i came across with how to provide them with the dynamic properties and events like they have created a button dynamically inside a group control but what good a button be if i cannot give it an event dynamically. in the same way i want to add a tree view inside a vbox but what good that be if cannot provide a data provider to it dynamically.actually i am creating an web application where i add the tree view to a vbox and i want to the data provider should also be dynamic depending upon the option i have selected in the combo box.

This is the scenario:
[AS]
// Assuming a lot more properties are added to all objects
var parent:Object = new Object();
var kid:Object = new Object();
var kidToy = new Object();

Does making the parent object null recursively release all memory used by all subordinates in the hierarchy?

If I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation;
object.rotation = 0;
var normalizedWidth = object.width;

I'm using a custom right click context menu for a flash app (overriding the default adobe menu). For this Uza's right click solution [URL] works well.
However, flash player plugin (for Firefox/Chrome etc) has a bug which breaks usage of international characters when its using WMode for the html embed. WMode="widnow" works.

The issue can be seen better here -

I want 3 comboBoxes. The choices in the first and second will determine what will be displayed in the 3rd box. E.g.
1st box - Choose a genre of music (Rock; Pop; Dance etc.)
2nd box - Choose your county
3rd box will display a list of gigs of your chosen genre in the county selected.
Upon choosing a listing in the 3rd box a dynamic text box will display details (address; contact number; price; web address etc).

I have a flash site that users can view full Screen video. the trouble is, I am making only the video player full screen (hiding the rest of the site behind it).
my "toggle full screen" button works in that it reduces the video player back to normal size when the user toggles out of full screen back.
but when the user hits the escape key, my flash script doesn't know that the video player should be reduced in size.
it seems there's no way to capture the ESCAPE key as a key event

I have a video display in my flex app. which is attached to the camera. The camera resolution can vary depending on the user's selection, While the video display (preview) dimensions are fixed. I am then doing this:
bmd.draw(vidDisplay);
Where bmd is the bitmap.. The problem is the resulting bitmap has the correct size of the camera settings (which is set) but the capture from the video is always the size of the video display inside the bitmap.. I hope i am making sense. The result looks like a little picture inside a bigger image top left justified. I want to have a video display preview with fixed height, but be able to take snapshot with varying resolution.
