Remove all event listeners

Similar Questions

• Is there a way to clear all event listeners, to stop all the video clips, etc.?

  Is there a syntax for that?

  I have a movie that has 15 images. Each image has integrated video clips in video clips, tons of entertainment and event listeners. None is needed except when they are on the scene, on the frame. However, the animations continue even when the frame is left.

  For example, I have a framework that shows a rendered animation dynamically the leaves that fall from the tree. When the frame is left, the leaves continue to decline.

  There are many cases of this kind of thing happens.

  
  Ideally, I'd like to just be able to erase everything when a new image is loaded, since no animations or postponed event from one image to the other listeners.

  
  Is it possible to do it without the thousands of lines of code it would take to manually remove all single animation and event listener and sounds, etc., of the scene?

  Thank you very much!

  You must do it manually.

  or, you can convert each image into a swf file.  load each swf when necessary and, if you're publishing to fp 10 +, you can apply unloadAndStop() to kill all the flows in the SWF loaded and ready these assets to gc.

• 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.

• To remove all listeners and/or all links?

  Hello

  Is it possible in JavaFX 8 to remove all listeners change/cancellation on an observable?

  And is it possible to remove all the links on a property?

  Thank you

  Graham

  Is it possible in JavaFX 8 to remove all listeners change/cancellation on an observable?

  When parameterListener is passed to removeListener(), implementation goes through the list of all the listeners of change/cancellation. He calls parameterListener.equals on each of the listeners in the list and remove the first of so that it returns true. Therefore, the answer is technically Yes. However, you can't directly access the list of the headphones and it is not recommended that you remove any listener that you have added yourself.

  And is it possible to remove all the links on a property?

  If you know everything that was related to it. But I don't think that you have access to the internal list of all things related.

• Remove all listeners - or another solution to the given problem

  If the problem is the following:
  
  Say we have a list of items displayed in a ListView. The elements can be made up of a string describing and above all, a list of IDs.
  
  Then we have a group of checkboxes, each associated with a value ID. The check boxes are selected must be determined by the content of the list of the selected item in the ListView.
  
  For example, the elements may be individuals, and IDS can refer to his hobbies or whatever - typical example. If you have a group of predefined leisure displays that you can check if the particular person has them or not.
  
  Therefore, the behavior that we want to:
  
  (1) when the selected item in the ListView is changed, update the boxes to display the ID of this item.
  
  It is trivial. Simply add a listener on the selected ListView item and for each checkbox, set it to enabled if the list contains the corresponding id.
  
  (2) when an any of the boxes is changed by the user, update the list of IDS to the selected ListView item.
  
  This seems to be is not as trivial as it may seem. :)
  
  The first thing I tried was:
  
  Add a listener for invalidation fixed for each of the boxes. In Manager, a list of all ID-checked, and updated list of the current selected ListView with the latter item.
  
  The problem here is him when you select an item in the ListView and behavior in 1) is called, the invalidation handler is called, thus updating list of the selected ListView item again before it has had the opportunity to update all the boxes!
  
  Next thing I tried:
  
  Do not add any fixed listener for the check boxes. (Instead, in 1), remove the check boxes for any listener, to update, and then add a listener that will call the behavior in 2).
  
  The problem here is 'remove every listener of the boxes', given that on Observable removeListener() method takes a specific listener as a parameter - and we have no reference to that. (And the first time, we have not added even.)
  
  So is there a way to tell an Observable, Hey, remove all listeners you have?
  
  Or am I on the wrong track, and it is indeed obvious, another solution to this problem?

  I don't see the need to remove the listeners - this seems dirty and a little prone to error.

  What follows is doing what you want (I used a ChoiceBox for ease, but adapting to a list would be trivial), or if I'm missing a part of the question?

• removeChild removes the object event listeners?

  Hello

  If you dynamically create a parent movieclip, dynamically add a selector of color of each element and add an event listener for each color picker, a removeChild on the parent movieClip removes event listeners belonging to one of her children?

  Thank you

  Shaun

  It should not.  You only delete the object from the display list, not existence.  It's still there, you don't see it, but you can bring it to life too fast that reuse addChild.

• Smartphones blackBerry how to remove all calendar events?

  I am a new BB user (changed of the years as a Palm bigot) who bought just a "BOLD". I do not use a BES to sync but use the BB Desktop Mgr for calendar and contacts.

  After my first couple of USB sync, I have duplicate calendar on my device that must be deleted. My outlook calendar is "free duplication", but the unit needs to be cleaned up clean of the calendar events, so I can start again.

  How can I delete all events in the calendar of my "BOLD" device so I can sync it with a clean Outlook start?

• 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.

• How to remove the event listener when all the MoviClip are out of the scene

  I am newbie to as3,

  I created the animation using as3 in which duplicate the circle ten times, then push in a table and giving random motion.

  use:

• Event listeners generate errors while the modal windows are shown.

  Hi all

  I have an interface in ui script that relies on headphones for events initialized as follows:

  		var button = palette.add ('image', rect);
  		button.onDraw = buttonDraw;
  		button.addEventListener ('mouseover', onMouse, false);
  		button.addEventListener (onMouse, 'mouseout/mouseouthandler()', false);
  		button.addEventListener ("mousedown", onMouse, false);
  		button.addEventListener ("mouseup", onMouse, false ");

  I need these events if I change images (false buttons) when the user moves the mouse over them or click on one of them. Everything works as it should, until I decided to give something back. Although made in After Effects, a window or something is open somewhere and it makes all the unnecessary scripts, they do not meet the entry to any user, and it is very good for me. It works the same for all of the scripts that I tested.

  The real problem is with event listeners. The scripts that use will generate them a substantive error if no listener is enabled. And when rendering finished, AE will display a pop-up allowing you to know these errors. Also the interface script stops turning completely until you close open again.

  The error message is:

  "Cannot run a script so that a modal dialog box is waiting for answer".

  I thought to replace all the headphones by the other type of reminder like 'onClick', but it seems that there is no work around to "mouseover" or "mouseout/mouseouthandler()".

  It is a real problem for my user interface, as if the user has my Panel anchored somewhere in the interface and simply move the mouse on one of the buttons, it will end with the error at the end to make it. There are also I can't do anything to avoid the listeners to run, because once the script is loaded, we lose all control of what goes with it, no way to temporarily remove listeners.

  Any ideas on how to solve this problem?

  I found a solution to my problem.

  I had to remove the listenerer of the 'mouseout/mouseouthandler()' event when my custom onDraw function has been executed as a result of the actual mouse out (in other words drawing my picture in the iddle version). Then I just reinstall the event "mouseout/mouseouthandler()" at the "mouseover" event is triggered.

  I also tried to remove the "mouseout/mouseouthandler()" in my function onMouseOut listener, but it did not work very well, the only way was to remove it in the custom onDraw.

  Another thing, I discovered, is that the "mouseout/mouseouthandler()" event is actually fired 2 times... every time! That's probably a bug.

  I'll mark this as answered even if it's more as a workaround that dirty a real difficulty. I think it's a bug in After Effects (at least).

  UQg about your question, do you have a thread for it? Otherwise, you need to create one, I also have this problem and I'll look into it.

• to view the consecutive words in a table on a press of a key. Event listeners does not.

  I need to display a series of words consecutively on a black background. A new Word presented whenever you press the Enter key (it is necessary that it is the same key IE each time the Enter key). The words are arranged in a table. I created a function for each button press and a listener. Also, as the previous word is replaced by the following, I have a removeChild() to get rid of the the last word.

  I have a set removeEventListener in place too, to avoid problems with listeners. To this, I've been long without success. It must be an earpiece problem (IE I do not have the doors correctly listeners?) or a display problem. It always shows only one. Please find below the code for the display of two of the words in the table called cvcwords. The main problem is that the words are not displayed one after the other (actually not at all, except for the first) when you press the Enter key. Very much as a powerpoint presentation, that's the idea anyway. I have just a sample of the code below. any help appreciated.

  var cvcwords: Table = ["bad", "mod", "hud", "mit", "sat", "fog", "puc",];

  this. stage.addEventListener (KeyboardEvent. ) KEY_DOWN, modKeyDown);

  Function modKeyDown (e: KeyboardEvent): void {}

  if (e.keyCode is keyboard. ( ENTER) {

  removeChild (myText);               / / to remove back Word of screen

  myText.text = cvcwords [1];        //to View element un of le table

  addChild (myText);

  } else If (e.keyCode == keyboard. ) SPACE) { //this is distinct from the other for option }

  myText.text = "try again";

  addChild (myText);

  this. stage.removeEventListener (KeyboardEvent. ) KEY_DOWN, modKeyDown);

  }

  }

  this. stage.addEventListener (KeyboardEvent. ) KEY_DOWN, hudKeyDown);

  Function hudKeyDown (e: KeyboardEvent): void {}

  if (e.keyCode is keyboard. ( ENTER) {

  removeChild (myText);  to delete the previous word of the screen

  myText.text = cvcwords [2];

  addChild (myText);

  } else If (e.keyCode == keyboard. ) SPACE) {}

  myText.text = "start";

  addChild (myText);

  this. stage.removeEventListener (KeyboardEvent. ) KEY_DOWN, hudKeyDown);

  }

  }

  
  

  From what I see of your code, the following is everything you need...

  var cvcwords: Array = ["bad", "mod", "hud", "mit", "sit", "fog", "puc",];
  var count: int = 0;

  stage.addEventListener (KeyboardEvent.KEY_DOWN, modKeyDown);

  function modKeyDown(e: KeyboardEvent): void {}
  If (e.keyCode == Keyboard.ENTER) {}
  myText.text = cvcwords [counter];

  counter ++;
  } Else if (e.keyCode == Keyboard.SPACE) {}

  myText.text = "try" again
  addChild (myText);
  stage.removeEventListener (KeyboardEvent.KEY_DOWN, modKeyDown);
  }
  }

  When you test this in Flash, in the drive to be sure, you will need to select the option of Devil keyboard shortcuts located under the control option in the top toolbar

  If you really want to tell them to try again, probably not wanting to remove the event listener

• How to remove an event listener

  I have a series of buttons. When a button is clicked, a component (instructorView) is loaded into a container named passageContainer:

  passageContainer.addChild (instructorView);

  Every time I load a new component, I remove the component of the old first:

  passageContainer.removeAllChildren ();

  The component includes an eventListener that is raised when a key is pressed.

  The first time I load a component and you press a button, the event is triggered once.

  The second time that the event is triggered two times.

  The third time the event is fired three times and so on.

  I'm almost certain that the eventListeners are not removed even if the components are removed. And event listeners to perform several times.

  Is it possible for the eventListeners to stay after the components have been removed? If so, how can I remove them?

  Thank you!

  This means that the components are always in memory, they are tightly coupled, you need to makesure that the event listeners are weakly couples/weakreferenced.

  http://www.Selikoff.NET/2010/09/21/Flex-event-handlers-and-weak-references/

  (OR) to remove the earphones manually, by this.removeEventLIstener (on each component for all events that are saved in the component before remove you it from memory.

• "master password" not recognized, it is not send me an email, if I reset my master password - it will remove all my passwords on my computer or just mazilla?

  I tried several times and it does not recognize my master password. In fact, I had a similar problem with the usual password before going with the master.
  If I reset the 'master' password, I need to know that it will not erase all of my passwords where I use them as ebay, Apple, or emails. I don't want to be locked off sites or the loose them on this computer.
  When you say that it removes all, do you mean just the ones that I entered for firefox? WHAT DO YOU MEAN IT WILL REMOVE ALL? from my computer?
