• Remove the event listener, or y at - there no need?

  Gidday

  If I set up an event listener in a private function

  for example

  var myfile:File = new File();

  myfile.addEventListener (Event.SELECT, loadmyfile, false, 0, true);

  myfile.browseForOpen ("Select a file to import...", [myfileFilter]);

  what I have to remove the listener in loadmyfile(), or the listener goes away once Flash has left the current private function as var myfile was created at the breast of this?

  Thank you guys

  MyFile should be garbage collected (gc would be) because you have assigned the listener to be low with your last setting (and myfile is local to your service - private or public or otherwise, does not matter).  but there are so many problems with all that you are better off using a weak listener AND the removal of the listener.

  a bit of a stretch is better than underkill and gc system can use all the help it can get.

• 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");
  }
  
  private function myImage_completeHandler(event:Event):void
  {
       myImage.removeEventListener("complete",myImage_completeHandler);

  Remove. EventListener should be removeEventListener

• The proper way to remove a listener for loader events

  Hello.

  I´d would like to know what is the rigth way to remove a listener for loader events?

  Like this?

  loader.contentLoaderInfo.removeEventListener (ProgressEvent.PROGRESS, onProgressData)
  loader.contentLoaderInfo.removeEventListener (Event.INIT, onInit)

  Thank you

  I find the best way to remove them is to make them the same way you added, replacing 'Add' with 'delete'... it seems that you did in your example.

• [noob] Help understand why the event listener continues even after the withdrawal.

  Hey again,

  I'll try to do my best to explain. I can get this to work properly, but I'd like to understand why what I did before was not working.

  I have a little trouble understanding why an event listener continues listening to even after that I delete it. I have a facility where a Parent MovieClip ("CampScene") is established and an event listener is added to the look for a function ("walkUpToCampfire") to see if a condition is true ("comingFromAx is true", that won't be true until later).

  If it is true, an animation plays, an event listener is added to see if the animation is made and if it's an event listener is added to listen for a click ("campScene.goToAx") to a new animation to play and other events. (It won't be true until later.)

  If this isn't true (which is the situation that I work with at the start), the event listener said listening for a click on "campScene.goToAx" is implemented immediately. The function following removes the event listener, so it is supposed to stop listening to a click and let an animation play throughout.

  The problem is a continuous click to be listened to and if you keep clicking on the reboot of animation every time, which is what I don't want to happen.

  --------------------------------------

  I'm able to resolve the problem by adding the line "campScene.removeEventListener (Event.ENTER_FRAME, walkUpToCampfire)"; or in mouseEnabled affecting false for "campScene.goToAx", but I try to understand what is happening.

  It is, even if I'm deleting the listener ("campScene.goToAx") in a function ("goToAxScene"), "campScene.addEventListener (Event.ENTER_FRAME, walkUpToCampfire)"; continues to wait for a mouse click, unless it is removed also?

  Again, I am trying to understand how it works.

  --------------------------------------

  This should be all ACEs. Of course, I would like to know if you need more information. (I can post the FLA / AS files if need be.)

  campScene.guyAtCampScene.gotoAndPlay ("guyGoingToAx");
  
  check the label to see if axScene must appear
  campScene.guyAtCampScene.addEventListener (Event.ENTER_FRAME, addScene);
  }
  

  Your best bet to solve why things happen is to make use of the trace function.  In this case, you may have a trace run every time this listener can addedand any time it is deleted.  In this way, you should be able to see if it was added in after he deleted.  If there are several places where it is added, then adjust your tracks to indicate which line is involved as well.

• Removing event listeners - are they need all the time

  My goal is to increase the performance of my project, so I would like to know if it's always a good idea to remove event listeners. Specifically, let's say I have a movie with several scenes and several frames in these scenes. Each image has an event listener:

  Example:

  Scene 1

  Image 1 (EventListener)

  Frame 2 (EventListener)

  Frame 3 (EventListener)

  Framework 4 (EventListener)

  Scene 2

  Image 1 (EventListener)

  Frame 2 (EventListener)

  Frame 3 (EventListener)

  Framework 4 (EventListener)

  Questions:

  1. Flash continues to listen to an event in the scene 1/frame 1 when the playhead on stage 1 / 2 frame?
  2. Or Flash just listening events when the playhead is in a particular frame only?
  3. Should I remove the event listener once I leave a specific frame (should there be event listeners remove on each image)?

  You must remove event if listeners is no longer necessary.

  scenes do not yet exist in your published swf file.  they exist only in the ide to help you organize your project, but the more advanced flash users avoid using scenes because they do nothing useful, once you get a deeper understanding of flash.

  so, it makes no difference what the read head scene is because the flash player doesn't know which scene is that.  those who are righteous (marked) frames on scenario main and each scene begins with a keyframe void (unless and until you put something in that keyframe).

• Even if I put a null componet and remove parent... again for important to remove event listeners?

  I'm confused about something. My Essential Action Script book mentions that you should really remove all registry event listeners when you use is no longer the component when it is defined. It applies even if its parent container is removed and you set the null object? The garbage collector should not take care to destroy the event listener registered as well since it was registered in the component that you have set to null?

  When you set a component to null, what you are defining this particular reference to null, is no no not the object itself null. The event listener maintains a reference to the component, and given that the number of references so that the object is greater than zero, it is not the garbage collector.

  You can work around this problem by setting the useWeakReference flag in the call addEventListener() to true. Be careful with this, however. If you use a weak reference, and do not remove the event listener, you can always react to events lifted between the time when it is removed and when he is recovered by garbage collected. It is generally safe, but if there are events that are triggered by a timer, that could be a problem.

• Event listener to sleep

  Is it possible to do an event listener "sleep" for 5 seconds and then make it active again?

  
  IM thinking something like this:

  remove the event listener;

  wait 5 seconds;

  Is someone can you please tell me how I can do?

  Thank you

  Use the timer or setTimeout class to add your listener after a delay.

• the click event listener smile ActionScript 3.0 works only once

  I am a newbie. I use actionscript 3.0 and I have a file .as separated with all my action script code. I have 2 buttons called myBtn1 and myBtn2 in my .fla including the base class file is two flash.display.SimpleButton.
  The event listener for myBtn1 (buttonClickHandler) always fire correctly. But the eventHandler for myBtn2 (textClickHandler) fires once and only if myBtn2 is the first button click. (I know that these event handlers and instructions switch sounds pretty ridiculous with a single element of each, but I removed the code).
  Why textClickHandler only seems to work once?
  Any help would be greatly appreciated!
  
  

  According to one of the Adobe Technical Notes sometimes the event mouse move is missed by the DisplayObject, thus, rather than attach the listener to the stage. Which works very well. So now instead of
  
myBtn1.addEventListener(MouseEvent.CLICK,buttonClickHandler);
myBtn2.addEventListener(MouseEvent.CLICK,buttonClickHandler);

  I have
  
stage.addEventListener(MouseEvent.CLICK,buttonClickHandler);

• URGENT: Problem of EVENT listener

  Hi all
  Thanks for your time. I am facing a little problem with the event dispatcher and the event listener to be added. Well, I'll explain the problem.
  
  I have a MovieClip named BUTTON_SET and I gave "ButtonSet.as" class link.
  Inside this BUTTON_SET, I'll have a few buttons and they also have "UIButton.as" as a binding class
  
  UIButton expedition press and release events, but unable to capture it using the button class. Here, I enclose the Code and I gave the URL Source too.
  
  to my knowledge: UIButton class is not triggered when the button is ready for addListener.
  Please help me solve this problem.
  
  If I can't find a solution, I need to change all my class structures.
  
  CLICK HERE TO SEE THE SOURCE CODE
  
  

  According to your Code, when you call the InitHandler Functionction buttons may or may not be launched. Then use the Enterframe to check if its charging or not.

  Note that in the button to replace the Manager call init.

  this.onEnterFrame = Delegate.create (this, initHandler);

  a_l'_interieur_de this initHandler, remove the function that will help you if you do not use any Enterframe for any other manipulation)

  delete this.onEnterFrame;

• How can I create an event listener for the change of variable shared or similar?

  Hello

  I have a 'big' 6 devices communicating measurement system via the TCP protocol. The system is designed to use REST (the representative State transfer) with JSON (JavaScript object notation).

  Now, I need to add labview program to this environment. I've implemented a solution to 'work' with the help of this forum. Thank you for this! Now, I need to do better (currently no timestamps, large delays, etc.).

  I currently have a web service deployed using http-get as input. My web service .vi is just passing the web entrance to shared variables that are then questioned in real measurement program. Reason is that when I put the measurement program directly to the web service, it does not (something about rights and dependencies). Measurement program includes one third of the owners (Instron) drivers. Also I would not direct access via the network to our mechanical testing device potentially dangerous.

  Now, I want to change the message from the web services .vi commensurate .vi. Currently I have a loop of 10ms to query for changes in the shared variable. Is there a better way to do this? I thought create a listener to the shared variable change events.

  In addition, if you have any ideas (preferably, working code example) how to make the interface between labview and TCP-JSON I would really appreciate it.

  BR,

  Juha

  Currently in LabVIEW, the only way to create an event listener or event NSV is to use the DSC toolkit.  Most of the time the DSC is a very expensive tool that simply encapsulates the functionality that is built into the motor of the PSP and OAS and which is accessible to anyone who can program in LabWindows/CVI.

  http://zone.NI.com/reference/en-XX/help/370051P-01/CVI/libref/cvicnvcreatesubscriber/

  If you want to collaborate, I would like to create a small library of LV that would create a base SV events using a vi LV reminder or possibly passing return user LV event which is how works the DSC toolkit.  I asked OR several times to explain how do this and they're very tight discreet about it.  I guess that they do not want to give users LV less reason to buy the DSC.

• Launch Global event listener when auto start MyApp

  What I was trying to do:

  MyApp has an alternative entry point and the graphical user interface.

  access to choice, I wanto save a folderlistener that triggers a global event to trigger an email sending process.

  so far, I've only had the entire process running only if I join the global event listener in the GUI part, it means when myapp GUI stood then go global Stanley knitted.

  but I want Global event listener remains all the time, how can I do this?

  I did some research in this Ant but just couldn't understand it

  any responses appreciated.

  my code:

  ============================================

  SerializableAttribute public class MyApp extends UiApplication implements FieldChangeListener, GlobalEventListener
  {

  Public Shared Sub main (String [] args) throws AddressException, ClassNotFoundException
  {
  MyApp PAP;
  If (args! = null & args.length > 0) {}
  {If (args.length > 0 & {args [0].equals("Auto-MyApp")})}
            
  Entered another application by the entry point.
  Turn on folderlistener at startup.
  FolderListenerApp.waitForSingleton ();
             
  }
  else {}
  PAP = new MyApp();
  theApp.enterEventDispatcher ();

  Is it the GlobalEvent we expect?
            
  If (guid is 0xa4c7e78a6c3fe109L)
  {
  Yes.

  FolderListenerAction f = new FolderListenerAction();
  New Thread (fa) m:System.NET.HttpListener.start ();
  }
         
  }

  }

  ==================================

  Check out this tutorial that I posted earlier, it shows an application that is divided into a background process (extends the Application and begins when the operating system starts) and a process of foregroud/AC (extends UiApplication).

  Both are implementing GlobalEventListener and use it to talk with them
