Add event listeners in a loop?

• Add event listeners to the symbols loaded dynamically?

  Hello

  I'm trying to dynamically load a different MovieClips based on user input. Many of these clips have incorporated symbols of url link. How can I add events for url links listeners if the loaded MovieClip dynamically does not have an instance name? Looks like I can apply (right?) an instance name when the video loads, but the event listener does not compile because the name is not there yet, what seems to get out.

  I'm on the right track?

  You say you'll instnatiate this symbol several times and each time for that link url will be different?

  We list two ways to treat.

  1. inside of the symbol you can send a personal once event on:

  myLink.addeventListener(MouseEvent.CLICK, onClick);
  function onClick(e:MouseEvent):void {
       dispatchEvent(new Event("linkClick"));
  }
  

  When you instantiate the symbol (maybe on the timeline):

  var symbolInstance:MySymbol = new MySymbol();
  symbolInstance.addEventListener("linkClick", onLinkClick);
  function onLinkClick(e:Event):void {
       // do whatever
  }
  

  Second way would be to pass the value of the url in an instance of the symbol itself and deal with it on a symbol level. I personally prefer way 1.

• Add event listeners to the child of the child

  Hello!

  I have this little class where I load a charger and turn it into a movieclip (and some other stuff).

  I also have this larger class where I have a lot of the classes bit.  And in trying to arrange them correctly, I use their width and height and stuff.

  But I guess that since it takes little time for classes to load and convert to movieclip and other things, when I access the width and the height of them in the large class, they are all zero.

  What I do now is sort of ugly, where after I convert/add the movieclip, I send the event bubbling in the smallest class and literally add them upward in the parent class until they are all done.

  What I tried to do was Add Event.ADDED variable of movieclip in small classes, great class.

  as:

  littleclass1. MC.addEventListener (Event.Added, blah);

  littleclass2. "MC." "

  But that did not work and was just as ugly!

  So basically my question is... do I make in the class of the child or the parent class as... I can just create, add it and have all the items width and height and ready stuff immediately the bat (regardless now of many movieclips, loaders, sounds, sprites in the smallest class)?

  As a dispatch ' ok everything is all done here, now, you can access my width and height with precision.

  What isnew laptop.inbox("1")?

  If it is a symbol in the library that contains an element, then use the render event, or that contains shapes in a framework other 1 contributing to the width/height that you are trying to access, and then send an event from a frame other than a callback function.

  If it is a class in which you build objects, then shipping and event or use a reminder works when the width and height are ready to go.

• How to add events to the array elements?

  Hello.

  I have the table with 5 boxes.

  I show as boxes on the stage that + having shown that it is random.

  Now, I want to add events to this boxes.

  For example if I click for box1 I have to go to "p4", if I click to other boxes that I have to go to "p3".

  I'm trying to do the same thing as for the buttons, but its does not work:

  classNames[0].addEventListener(MouseEvent.CLICK, goCorrect);
  function goCorrect(event:MouseEvent):void {
       trace("p4");
       gotoAndStop('p4');
  }
  
  classNames[1].addEventListener(MouseEvent.CLICK, goWrong);
  function goWrong(event:MouseEvent):void {
       trace("p3");
       gotoAndStop('p3');
  }
  

  All the code in the code here:

  var classNames:Array=["box1","box2","box3","box4","box5"];
  var boxesList:Array=[];
  var ClassRef:Class;
  
  for (var i:int = 0; i < classNames.length; i++) {
       ClassRef=Class(getDefinitionByName(classNames[i]));
       boxesList[i] = new ClassRef();
       addChild(boxesList[i]);
  }
  
  var currentBox:MovieClip;
  
  
  var nextX:Number=0;
  for (var iii:int = 0; iii < classNames.length; iii++) {
       currentBox=boxesList[iii];
       currentBox.x=nextX;
       nextX+=currentBox.width;
  }
  
  
  for (iii= 0; iii < 1*boxesList.length; iii++) {
       var pos1:int = (Math.random()*1000) %boxesList.length;
       var pos2:int = (Math.random()*1000) %boxesList.length;
  
       if (pos1!=pos2) {
            var temp:int=boxesList[pos1].x;
            boxesList[pos1].x=boxesList[pos2].x;
            boxesList[pos2].x=temp;
       }
  }
  
  myBox1.visible=false;
  
  
  classNames[0].addEventListener(MouseEvent.CLICK, goCorrect);
  function goCorrect(event:MouseEvent):void {
       trace("p4");
       gotoAndStop('p4');
  }
  
  classNames[1].addEventListener(MouseEvent.CLICK, goWrong);
  function goWrong(event:MouseEvent):void {
       trace("p3");
       gotoAndStop('p3');
  }
  //box1.useHandCursor=true;
  

  You cannot add event listeners to the objects that send events. Generally speaking, an object that you want to send events should extend the EventDispatcher class.

  In your case, you add event listener for the classNames group members that are strings. String not to send events. So, you have to add listeners to events for objects that you instantiate while loop if classNames - these items are (I presume that these are instances of MovieClip, which stretches from EventDispatcher). Therefore, in your case, you can do the following:

  MovieClip(boxesList[0]).addEventListener(MouseEvent.CLICK, goCorrect);function goCorrect(event:MouseEvent):void {     trace("p4");     gotoAndStop('p4');}
  
  MovieClip(boxesList[1]).addEventListener(MouseEvent.CLICK, goWrong);function goWrong(event:MouseEvent):void {     trace("p3");     gotoAndStop('p3');}
  

• 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.

• Delete several event listeners.

  Hello

  In some cases, it is important to eliminate several event listeners in order to reduce the time CPU.

  Below is the code btn [i] .removeEventListener (event.type, arguments.callee); to //x doesn't seem to work.

  var btn:Array = (mc1, mc2);

  
  

  main.addEventListener (MouseEvent.CLICK, click);

  MC1.addEventListener (MouseEvent.Click, One);

  MC2.addEventListener (MouseEvent.Click, Two);

  
  

  function Click(event:MouseEvent):void

  {

  for (var i: uint = 0; i < btn.length; i ++)

       {

  event.currentTarget.removeEventListener (event.type, arguments.callee);

  x [i] BTN .removeEventListener (event.type, arguments.callee);

  trace(BTN[i]); [object MovieClip] twice, including mc1 and mc2 respectively.

       }

  }

  function one(event:MouseEvent):void

  {

  trace ("mc1", event.currentTarget + event.type); [object MovieClip] mc1 click.

  }

  function two(event:MouseEvent):void

  {

  trace ("mc2", event.currentTarget + event.type); mc2 click [object MovieClip].

  }

  Note that if we put code event.currentTarget.removeEventListener (event.type, arguments.callee), inside the Click function, it removes the listener very well.

  The problem may be with the table, but the trace in the loop of return [object MovieClip] twice.

  No, except if you know or can derive listener functions references:

  var btn:Array = (mc1, mc2);

  var f: Array = [1, 2]

  
  

  main.addEventListener (MouseEvent.CLICK, click);

  MC1.addEventListener (MouseEvent.Click, One);

  MC2.addEventListener (MouseEvent.Click, Two);

  
  

  function Click(event:MouseEvent):void

  {

  for (var i: uint = 0; i

  {

  event.currentTarget.removeEventListener (event.type, arguments.callee);

  BTN [i] .removeEventListener (event.type, f [i]);

  trace(BTN[i]); [object MovieClip] twice, including mc1 and mc2 respectively.

  }

  }

  function one(event:MouseEvent):void

  {

  trace ("mc1", event.currentTarget + event.type); [object MovieClip] mc1 click.

  }

  function two(event:MouseEvent):void

  {

  trace ("mc2", event.currentTarget + event.type); mc2 click [object MovieClip].

  }

• 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.

• Closure of a state machine in queue event with several parallel loops

  I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)

  I look forward to any comments on my as well code, if someone is willing to offer it.

  My program needs:

  If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.

  Architectural details:

  The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.

  During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".

  In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".

  HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.

  I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.

  I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.

  Thank you!

  First of all, close the notifier outside loops with your queues.  Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

• Global events and global event listeners does not work!

  I don't know who to ask if I have questions about knowledge base articles so I'll post here.

  I want to push the alert as how dialog box integrated calendar alerts to users. I understand that I need to use the globalevents and listeners, so I studied it in the knowledge base article below:

  http://supportforums.BlackBerry.com/T5/Java-development/global-events-and-global-event-listeners/TA-...

  However, when I run the code, it does nothing. The way it is set up, it should display messages ("received event, sending accused of receipt and acknowledgement received"), but nothing happens on my Simulator, once I have 'fire' of the global event. Help, please!

  No problem. We were all there at one point.

  Each of these files has a main method that is your entry point to the application. Since everyone has one, they all have two need to have their own projects.

  For example, to create a new project for each of these files in Eclipse (or JDE; Eclipse preferred) and drop the code in., and then run the two projects on the Simulator.

  Once both applications on the sim card, you can then view the interaction between the two applications.

• callback method vs event listeners

  I'm developing a game in AS 3 with the MVC pattern. In my document class, I created around 15 event listeners to refresh the view of the game.

  My question is that event listeners can I use function call back?.

  I tested the sample file by replacing the addeventlisteners with the callback function. It works very well.

  I think that compared to eventlisteners, call will be back took less memory only ().

  Any suggestion please?

  Thanks in advance

  Callback functions are more efficient. Event listeners allow a greater degree of decoupling in some cases, because you don't need often to know where the thing is that you're listening and the thing to send the event has no need to know or care that if everyone is to listen. And as soon as you need more of a thing to listen to, reminders become more complex (see AS3 signals).

  With callbacks or event listeners, keep to are you the spirit given a reference to the purpose of listening to the sender object. Make sure you clean all upward when the object that listens is no longer in use, or you can end up with leaks memory.

• 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.

• Event listeners

  Hello guys, how are you?

  I work with ActionScript 2 event listeners and I have a question about adding listeners in an ActionScript class.

  I tried this way in the constructor method:

  this.onLoad = loadXML;
  This ["btnNext"]. onRelease = loadNext;
  This ["btnPrevious"]. onRelease = loadPrevious;
  This ["btnLearnMore"]. onRelease = more;

  These are the respective methods:

  private void loadXML () {};
  private void loadNext () {};

  ...

  I'm rusty with actionscript 2. So, could someone help me?

  Kind regards

  I'm glad you solved your problem. If you are ready, please mark the correct thread so we can find unanswered questions.

• 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).
