removeChild removes the object event listeners?

• RemovePopUp method removes the object from the display list?

  I'm setting up an AIR application that uses several pop-up windows, and I get as much memory as possible windows pop up closed at each Garbage Collection.  Reading through forums / Articles / documentation, I see instances of object created by pop ups stay in memory (No GC would be) up to:

  -all references to the object are = null (cancelled)

  -all receivers on the object are removed (or are weakly referenced)

  -l' object is removed from the display list.

  My question is:

  Does

  PopUpManager.removePopUp (this);

  remove the object from the display list?

  I use PopUpManager.createPopUp () to instantiate a container to display mx:TitleWindow objects.

  The pop-up closed deletion function, however, I'm not sure if it is 'removed from the display list' completely.

  A simple answer is the best, what moves me in the direction of answering the question. (Also useful: How can I see the objects in the display list at a certain point during execution of the application?)

  Thank you all!

  He,

  Yes, removePopUp removes it from the display list.

• Cannot remove the Image event listener

  I'm clearly missing something and would be grateful for the help.  I'm trying to run an event handler when a full picture of loading, then remove the Manager so that it does not once again the image needs to be reloaded later.

  The problem I'm having is that the event handler simple custom ' disappear, despite the call removeEventListener on the Image object.

  The following example illustrates the problem (the example do anything useful... it's just the shortest example to demonstrate the problem).  (To run the application, you will need to provide any file JPEG ol ' named 'myImage.jpg' in the directory 'src' to your project).

  What to expect to happen is:

  (1) at startup, the image loads and runs of loadComplete().

  2) loadComplete removes the event listener so that subsequent re-loads don't get re-triggers the Manager.  I want only the Manager to run once.

  3) 'loadComplete' should appear in the debug console.

  (4) a click on the button should display only 'change picture' in the debug console

  What I get instead is that Manager loadComplete is not removed, and whenever I click on the button, loadComplete runs when the image is re-load (i.e., each button click results in the showing in the debug console 'change picture' AND 'loadComplete' ).

  Hello

  You can only remove event listeners you added with the addEventListener() method in an ActionScript block. You cannot remove an event listener that has been defined in the MXML tag, even if it has been registered by using a call to the addEventListener () method that was made within an attribute of the tag.

  Check this page for reference.

  http://livedocs.Adobe.com/Flex/3/HTML/Help.HTML?content=events_05.html

  You can change the code a bit get it works

  
  
  private function myImage_creationCompleteHandler(event:FlexEvent):void
  {
       myImage.addEventListener("complete",myImage_completeHandler);
       myImage.load("myImage.jpg");

• How to remove the object from the stage

  Hello

  I am currently implementing an AS3 code that generates a snow effect on the scene.  I am using the code from this site, but has difficulty:

  http://www.Kirupa.com/developer/flashcs4/falling_snow_as3_cs4_pg5.htm

  I have no difficulty in implementing of the snow, but I can't understand how get rid of it once it's there!  Here's the code, I have:

  (main.as)

  main/public class extends MovieClip

  {

  var snowamount = 50;

  public void main()

  {

  scene9. SnowPlus.addEventListener (MouseEvent.MOUSE_DOWN, moresnow);

  {

  for (var i: int = 0; i < snowamount; i ++)

  {

  var newSnowFlake:Snowflake = new Snowflake();

  this.addChild (newSnowFlake);

  newSnowFlake.SetInitialProperties ();

  triggerSnowAnimation();

  }

  }

  function moresnow (MouseEvent): void

  snowamount += 20;

  makeItSnow();

  }

  function triggerSnowAnimation()

  {

  If (snowamount > = 160)

  {

  scene9.gotoAndPlay (3);

  scene9. SnowPlus.Visible = false;

  }

  The code is not so difficult to understand, in fact.  I have a button that adds "snowamount" to the variable, so more snow is done on the scene when the button is clicked.  However, once the "snowamount" gets above 160 bee, I trigger an animation.  Once the animation is completed, I want the snow to disappear from the scene.  But I can't understand the correct way to do everything.  Any help would be appreciated!  Thank you very much in advance.

  create an array and store your references to Snowflake in this table.  When you are ready to remove the snow flakes, loop in the table.

  main/public class extends MovieClip

  {

  var snowamount = 50;

  newSnowFlake.SetInitialProperties ();

  triggerSnowAnimation();

• [REQUEST] How to remove the object from the list to display and memory that added dynamic

  Hi there everyone,

  I have a question which I hope you guys can help me with, so the question is:

  
  "How to remove us (sprite object that has an external swf that it is child) display and, above all, of the memory, but we can still use the same variable to add another object (yes another sprite like the one we have removed yet a different content)..,

  I did tried the removeChildAt thing he did remove all the child of the display list, but I still can hear the sound of the video running.

  Here is the code on a small scale of what I do (sorry that I can only give you chunk code loading and adding)

  var SWFList:XMLList; used to contain a list of all the external swf source, atribute and etc.
  var totalSWF:int; the total number of swf external, it must be charged

  var swfLoader:Loader; instance of the loader class to load external swf file

  function loadSWF (): void
  {
  for (var i: Number; i < totalSWF; i ++)

  swfLoader = new Loader();
  swfLoader.contentLoaderInfo.addEventListener (Event.COMPLETE, onSWFLoadComplete);
  swfLoader.load (new URLRequest (SWFList [i], .@source));
  }

  function onSWFLoadComplete(e:Event):void

  {

  this.stage.addChild (e.target.content);

  }

  and also if you can give an example of a good method of dynamic add the object to the stage I would really appreciate cause I suspect mine are bad method.

  Thank you all.

  If you have been publishing for fp 10, just use unloadAndStop().

  I assume you're not publication for fp 10 so you have to use something like:

  function clearScreen (): void
  {
  var mc:MovieClip = MovieClip (swfLoader.content);

  MC.yourflvintheloadedswf.Stop ();

  mc.mcinyourloadedswfthathasalistener.removeEventListener (MouseEvent.CLICK, whateverF);

  etc.

  swfLoader.unload ();

• Remove the object or field from the tab order

  Hello

  I was wondering if there is a way to remove an object from the tab completely order.  Thus, when the user reaches the end of my set tab order they failed to hit 74 times tab to go beyond the computed text fields to return to the top of the order.

  Thank you

  The only solution I know is to use the setFocus method. The output of the last topic event you could add

  xfa.host.setFocus (form1.page1.subform1.firstField);

  drive focus to a field called "firstField.

• my content aware tool is not completely remove the object that I chose

  When I select an object to delete with content aware that he will remove all... it leaves a shadow of the object. I put it on the Normal and 100% opacity

  There is something that I have worked on the right after the College became available.  It is not always doing things, so the trick is to provide only pixels you are happy so he can get the fill of.  So imagine the image below with the floating stone.  Red is a selection marked by the quick mask, I've done very quickly with the lasso tool.  By copying the selection into a new layer and then by selecting the stone and using the CAF, you can be sure that it won't catch the pixels of the bird or gravel to fill the repair area.

• How to remove base class event listeners

  Guys, I have a base class (he is a clip) in which I added event listeners:

  addEventListener (MouseEvent.MOUSE_OVER, mouseOverHandler);

  OK, it works and everything is beautiful.

  But I have a subclass that clip in class 'regular ': as3

  class DifferentClass extends MyMovieClip

  {

  }

  you get the gist.

  Now, I want in my DifferentClass also have the MOUSE_OVER event, but without never to raise the base class event.

  No one knows how to do?

  Thank you.

  override protected function mouseOverHandler(e:MouseEvent):void {}

  do not call super. Instead, do your own thing custom

  }

  No need to call getQualifiedClassName. This is what has protected methods are for!

  Note You can also listen to a higher priority and the preventImmediatePropogation() on the event if for any reason any substitution does not work for you.

• List - remove the old events in bulk

  One of my sites has several thousand former events and we need a way to be able to archive them and remove them from the hosting platform. It would be great if we could download them and then remove them in bulk.

  Also, anyone know what the correct process is now to add to the wish list?

  see you soon

  Deb

  You cannot export the actual events, but you can export customer report and booking Site Settings > custom reports. BTW, bookings have been renamed to events in the main menu but elsewhere, they are always qualified bookings.

  But you need to remove one events.

• remove the onload event

  After the review of a Web page and the withdrawal / change some images, to the old images onload event is still in the body.  What I think is what is at the origin of the broken links appears in the link checker.  Is there an easy way to remove these old onload events without disturbing the onload for new images in use?  Should I still worry about this?  Thanks for any help you can provide.

  I just tested to be sure, but if I use the above IP tag selector, to select the body, I see the behavior in the behaviors panel, and if I double click the preload/Panel icon I get a list of images in proloaded and have the ability more or add images to will.

  I get the ability even if I place my cursor inside thecode in design mode.

  I'm afraid that if you get the option using the above, then you will need to remove it manually via the code view.

  Or you can select the body tag and just remove the behavior completely and then reapply the behavior and add only the images you need.

  Based on previous experiences and discussions, all you have to do is restart the server by stopping all the services of EPM, Reboot HFM server and then start all services.
