• How to use event.target.name in AS2?

  Thanks kglad, I could see how event.target.name in AS3 could make a button to load a movieclip with the same name.

  I do the same thing now in AS2, but don't know what to write instead of event.target.name.

  And so, at the present time, each button push information in a table and then a function that uses to decide what movieclip to tie to a holder after that he faded once and then fades new...

  BEGINNING OF THE GALLERY OF IMAGES *.
  Add images to the holder
  imgholder.attachMovie ("img0", "image0_0", 1).

  Table
  var nextLoad = ['img0'];

  Listeners of BTN
  img5.onRelease = function() {trace (nextLoad); nextLoad.pop (); nextLoad.push ("img5"); btnClick()} / / written on 1 line
  img4.onRelease = function() {trace (nextLoad); nextLoad.pop (); nextLoad.push ("img4"); btnClick()}
  img3.onRelease = function() {trace (nextLoad); nextLoad.pop (); nextLoad.push ("img3"); btnClick()}
  img2.onRelease = function() {trace (nextLoad); nextLoad.pop (); nextLoad.push ("img2"); btnClick()}
  img1.onRelease = function() {}
  nextLoad.pop ();
  nextLoad.push ("img1");
  btnClick()
  }
  img0.onRelease = function() {}
  nextLoad.pop ();
  nextLoad.push ("img0");
  btnClick()
  }

  
  The function of btn
  function btnClick() {}
  trace ('click');
  var myImgTween:Object = new Tween (imgholder, "_alpha", Strong.easeOut, 100, 0, 1, true ");
  myImgTween.onMotionFinished = function() {}
  fadeOutImg();
  }
  }

  The function part of II btn
  function fadeOutImg() {}
  trace ("fadeOutImg");
  imgholder.attachMovie (nextLoad, "image1_1", 1);
  var myImgTween:Object = new Tween (imgholder, "_alpha", Strong.easeOut, 0, 100, 1, true ");
  }

  I know I should be able to push the button name in the table, but I meet to use a string... I don't know that my code is heavy! But it works. I tried to push as the name of the button but it end by including the reference to full step.
  Is there a cleaner way to do this using event.target.name?
  Thanks for the research!

  There is no event.target in AS2. However since AS2 has no way to remember the scope object where the target object, you can use this to your advantage to get the name of the target using the command 'that' in the function when you use the format above "mc.onPress = myfunc". FYI, the delegate popular workaround solution, enabled when you called 'this' in the function, you can retrieve the scope object where the target instance. So without her help, "this" will return the name of the target object. In any case, this is the code that you can use:

  imgholder.attachMovie("img0","image0_0",1);

  var nextLoad = ['img0'];

  img5.onRelease = onImgRelease;

  img4.onRelease = onImgRelease;

  img3.onRelease = onImgRelease;

  img2.onRelease = onImgRelease;

  img1.onRelease = onImgRelease;

  img0.onRelease = onImgRelease;

  function onImgRelease (): Void {}

  nextLoad.pop ();

  nextLoad.push (this._name);

  btnClick();

  }

  The function of btn

  function btnClick() {}

  trace ("Click");

  var myImgTween:Object = new Tween (imgholder, "_alpha", Strong.easeOut, 100, 0, 1, true ");

  myImgTween.onMotionFinished = function() {}

  fadeOutImg();

  }

  }

  The function part of II btn

  function fadeOutImg() {}

  trace ("fadeOutImg");

  imgholder.attachMovie(nextLoad,"image1_1",1);

  var myImgTween:Object = new Tween (imgholder, "_alpha", Strong.easeOut, 0, 100, 1, true ");

• Problem in update of views presentation models

  Hi all

  I am trying to create a login using cairngorm screen and presentation model. I created a main screen that has two components - the screen logon and member. They appear according to the connection process. The problem is that even after the successful - connection, I can not update view.

  I know why - because I create two instances of presentation model for Main.mxml in Main.mxml and format for it.

  // Presentation model for Main.mxml
  public class MainModel {
       public var prop:String;
       public function callbackFunc( value:String ) {
            prop = value;
       }
  }
  

  // Presentation model for Login.mxml
  public class LoginModel {
       public function doLogin( username:String, password:String ) {
            var mainModel:MainModel = new MainModel(); // Instance created
            var event:LoginEvent = new LoginEvent( mainModel.callbackFunc, username, password );
            event.dispatch();
       }
  }
  

  <!-- Main.mxml -->
  <mx:Script>
  <![CDATA[
       [Bindable]
       public var model:MainModel = new MainModel(); // Another instance created
  ]]>
  <mx:ViewStack id="views" selectedIndex="{model.prop}">
       <views:MemberScreen />
       <views:Login />
  </mx:ViewStack>
  

  <!-- Login.mxml -->
  <mx:Script>
  <![CDATA[
       [Bindable]
       public var model:LoginModel = new LoginModel();
  ]]>
  <!-- form elements here -->
  <mx:Button label="login" id="btnLogin" click="{model.doLogin( 'abc', 'def' )}" />
  

  In this scenario, I make use of the callback function to the display to get updated when the loginEvent fires. But the view not updated because of two separate proceedings.

  How should I use the presentation model pattern in this scenario, as well as callback functions?

  Thanks and greetings

  You could do a Singleton to the principal so that way everywhere, you use it, you use the same instance of it. Or if you use the Cairngorm ModelLocator (not that I recommend) has a single instance of the principal and you access anywhere else via the ModelLocator.

• Automatic use at the request of resource blocks using not all solutions available resource locking

  Hello

  I'm trying to use TestStand with batch process model. I run lots of 8 EHR. Most of my tests have dedicated hardware, some use shared resources. As far as I can tell (and according to support NEITHER) the fastest way to run my test is to configure all tests in blocks using Auto demand for resources and just create enough resource Lock Alternatives for EHR 8 to use resources dedicated at the same time.

  If I create a single block of resources at the request of self employment with Alternatives to resource lock 8, it works perfectly. All EHR 8 run the test at the same time. However, if I add a second block of resources at the request of self employment with 8 Lock Alternatives resource (the same as in the first block, or with new unique names named) TestStand uses 4 of 8 Resource Lock Alternatives and my test takes twice as long as it should.

  Is it possible that I miss a setting, or configuration things wrong? I have attached a simple sequence that illustrates what I'm trying to do and a capture screen how TestStand runs it. TestStand 2014.

  Thank you very much for the help!

  I can't reproduce your behavior.  I have a quad core with all discussions on "logical".  So a total of 8 wires.  I modified your movie file to do 16 DUT to see if she could slow down.  I see about 7 seconds per report.

  We know that this is not the sequence file, because I run your movie file.  My guess is that there is another setting somewhere.  TestStand or in your operating system that is the cause.

  You have changed the model of batch processing?  I use out of the box one.  What version of TestStand?  I have 2014.  In Options of Station > preferences what is your processor affinity set?  Mine is - 1.

  Kind regards

• 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.

• 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.

• 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.

• 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).

• New in AS3: stupid question about event listeners...

  Hi all

  I am a newbie in Flash and have a question about event listeners. I have a site I'm developing with a movie clip navigation which is composed of several buttons. What is the right way to write the event listener?

  Here's a sample of what I have:

  I have a clip called 'buttons_mc' that contains the symbols of individual button with various names such as "btn_history". So far, I don't have an instance name for the clip of the film itself.

  My event listener:

  btn_history.addEventListener (MouseEvent.CLICK, history);

  I have to put something before the "btn_history" which refers to the video? I get this error message:

  1120: access of undefined property btn_history.

  Thank you!!!

  Julia

  Yes, it is preferable to have at least one layer dedicated to actionscript.  I often use a couple... one for code shared (functions and variables) and a level of the frame code (stop(), etc.).

  The code must be in a scenario where the button is directly accessible.  If your button is accessible in frame 1, which means that it does not animate in place such that it is not really intended to be used until you get somewhere near the bottom of the timeline, then you can target the button of the timeline that holds the buttons_mc movieclip.  So as I described earlier, if you give this movieclip an instance name of "buttons", and then to assign a code to the button on the inside you should use...

  Buttons.btn_history.addEventListener (MouseEvent.CLICK, history);

  But if the button exists somewhere down the timeline inside the buttons_mc due to the animation of the button, which means that there is more than one key image for the button, then you must place the code that you have initially shown in the last keyframe to the bottom of the timeline where he set the button in place.

• 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.

• Remove all event listeners

  If you have several running events listeners, is there a way to delete all at once rather than one at a time?

• To access the event listeners in the custom class

  I am a construction and film using the classes customized for the first time. I built a custom class and bound a clip in my film for her so that the color of the text in the video will change when he is overthrown. I have 10 occurrences of this clip in the film, so it saves me a lot of code. Instead of writing 10 to ROLL_OVER event listeners and 10 more for ROLL_OUT (as I have done in the past), one for each instance of the clip on the scene, I wrote now event listeners and the corresponding functions in the custom class. So far, so good, everything works fine. When I ride above and outside on one of the 10 instances of the clip on the stage it changes color. See code attached.
  
  However, according to what is happening in the film, that I sometimes need to turn off the headphones of events on one or more video clips. So, I wrote the code in the movie itself to remove event listeners of the instance of the clip that I need to disable. See code attached.
  
  But, alas, it does not work.
  
  I get this error:
  ReferenceError: Error #1065: Variable turnWhite is not defined.
  
  I thought that by the 'public' method in the custom class, I would be able to call from the film, but I do not. Any help or advice would be greatly appreciated. Thank you very much.

  Ned, thanks for your help. I was able to understand. Your code has been helpful, and I've used something similar to what you suggested.

  They are not. That's why I asked the question.

  Essbase displays the dimension members, i.e.

  Time
  + THE EXERCISE 2007
  + FISCAL 2008
  + FISCAL 2009
  ++ Qtr 01
  ++ Qtr 02
  ++ Qtr 03

  OBIEE displays the dimensional levels i.e.

  Time
  Year
  ID of the month
  Name of the month
  Day
  ID of the day
  Days of week
  Quarter

  In addition, you cannot member hierarchies displayed in the pane selection of answers. You may be using "->" in the old testament Description "-" in the name of the catalog of presentation, but what - this.
