• ERROR: Adding an event listener to a button in the main scenario

  I'm trying to get a simple script to work temporarily to show features. This file is a menu.swf file that loads below content.swf.
  
  There are 4 buttons on the main timeline and a stop at frame 40. On the same layer that my button is and frame 40, I have this code under actions. dineContent is the instance name of the button that I am referencing.
  
  However, I get access error 1120 property undefined.
  
  I know that I can add an event listener to an instance name. I have to create a film about all these buttons and then reference the instances of button inside the movie?
  

  I started playing with a bit more and found the solution.

  SOLUTION:
  in the property inspector to my instance of dineBtn named "dineContent", there is a contextual list under the "instance of: _" txt where you can choose between the track as button or Menu item.

  You must use the track as Menu item. the default value is button.

• Problem with event listener

  Hello

  We have an event listener that does not seem to receive all events insertion of a table.

  Here is the SYS. Order ADD_LISTENER that we use:

  call the SYS. ADD_LISTENER ('tpch ', 'SQLFIRE', 'lineitem', 'demo.vmware.sqlfire.greenplum.MultiHubProxyDispatcher',' connectionurl = jdbc:sqlfire: | numproxies = 4 | sqlfire = username: password = sqlfire ", null);

  MultiHubProxyDispatcher() code distributes the rows inserted between the four tables proxy (proxy_0 through proxy_4). I have attached the MultiHubProxyDispatcher() code in this post.

  Thus, after 2400 lines are inserted in the lines of only about 125 lineitem table are spread to each of the tables four proxy.

  sqlf > select count (*) in the sqlfire.lineitem;
  1
  -----------
  2400

  1 selected line
  sqlf > select count (*) in the sqlfire.proxy_0;
  1
  -----------
  125

  1 selected line
  sqlf > select count (*) in the sqlfire.proxy_0;
  1
  -----------
  125

  1 selected line
  sqlf > select count (*) in the sqlfire.proxy_1;
  1
  -----------
  129

  1 selected line

  This same event receiver code worked with SQLFire v1.0, we have recently updated to v1.0.3.1 and that's when we started to see the problem. I don't see anything unusual in the newspapers. Is there something that has changed with the SYS. Order ADD_LISTENER are we missing?

  Thank you
  Sean

  Hi Sean,.

  I think you want to attach the code for demo.vmware.sqlfire.greenplum.MultiHubProxyDispatcher but I see only MicroBatchListener.

  Looks like you are using both the AsyncEventListener, but also the listener to table which could be added through the SYS. Procedure ADD_LISTENER.

  Can you please write how you use the combination.

  Please note async event listener cannot be added through sys.ad_listener.

  Thank you

• 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;

• Strange problem with the keyboard event listener

  I have a full screen touch app. To close the application, I set an event listener on keyboard for the key "0". I don't want the press user due to some restrictions Alt + F4 key combination. Problems begin when the application loses focus. Here's the code;

  protected function onComplete(event:FlexEvent):void
  {

  this.setFocus ();
  this.addEventListener (KeyboardEvent.KEY_DOWN, trapKeys, true, 0, true);

  }

  private void trapKeys(e:KeyboardEvent):void {}
  
  If (e.keyCode == 96) {}
  This.Close ();
  }
  
  Else if (e.keyCode == 48) {}
  This.Close ();
  }
  
  }

  When the user change the screen to a different with Alt + TAB application, or any other combination of keys flex app loses focus and does not work when he turns back to my app "0". How can I solve this problem?

  Thanks in advance.

  Hi, Ahmed.

  I have absolutely no problem with the solution you are trying to set up - you use mode full-screen interactive mode of keyboard?

  Please consider:

  on full add keyboard listener

  protected function applicationCompleteHandler(event:FlexEvent):void

  {

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

  };

  //

  protected function applicationActivateHandler(event:AIREvent):void

  {

  If (this.stage)

  {

  switch the State to display full-screen when activated

  If (this.stage.displayState! = StageDisplayState.FULL_SCREEN_INTERACTIVE)

  {

  this.stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;

  };

  };

  };

  //

  private var exitHandled:Boolean = false;

  on NUMBER_0 | NUMPAD_0 exit-close

  protected function trapKeys(event:KeyboardEvent):void

  {

  If ((event.keyCode is Keyboard.NUMBER_0

  || event.keyCode is Keyboard.NUMPAD_0)

  (& this.exitHandled == false)

  {

  exitHandled = true;

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

  This.Close ();

  };

  }

  (Note: applicaton of the events 'applicatonComplete' and "applicationActivate" are routed to over managers)

  Kind regards

• Total frustration with adding event listener

  It's driving me crazy. I tried to do it for a few days now and I can't function. Everything seems to work properly, my images are loaded and land on the stage where I would like to, but I can't drag. It seems that the event listener (which I have highlighted) is not applied. Can someone tell me the error in my ways?  PLEASE?

  
  

  As a note, I did this same thing with the loading of the items in the library, and it works. I copied a lot of my project to test this code and when I load the bitmaps instead of out them of the library, it breaks.

  package {}

  import flash.display.MovieClip;
  Import 12345678910111213import;
  import flash.display.Loader;
  import flash.events. *;
  import flash.net.URLRequest;

  SerializableAttribute public class Main extends MovieClip {}

  var testImageArray:Array = new Array();
  var testImages:Array = new Array("177966","178006","700091");
  var xPos:int = 580;
  var yPos:int = 2;
  var yOffset:int = 0;

  public void Main() {}

  for (var i: uint = 0; i < testImages.length; i ++) {}
  loadThisImage (testImages [i]);
  }

  }

  function loadThisImage (imageName) {}
  var loader: Loader = new Loader();
  var req:URLRequest = new URLRequest("images/"+imageName+".jpg");

  loader.contentLoaderInfo.addEventListener (Event.COMPLETE, loadComplete);
  Loader.Load (req);

  }

  function loadComplete(event:Event):void {}
  var i: int

  testImageArray.push (addChild (event.target.content));

  I have = testImageArray.length;
  testImageArray [i-1].addEventListener(MouseEvent.MOUSE_DOWN,dragItem);

  testImageArray [i-1] .x = xPos;
  testImageArray there [i-1] = yPos;
  yPos += testImageArray [i-1] .height + 5;

  }

  
  function dragItem(event:MouseEvent):void {}
  trace ("Drag from");
  event.target.startDrag ();
  event.target.removeEventListener (MouseEvent.MOUSE_DOWN, dragItem);
  event.target.addEventListener (MouseEvent.MOUSE_UP, dropItem);
  }

  function dropItem(event:MouseEvent):void {}
  trace (Event.Target.Name);
  trace (Event.Target.x);
  trace (Event.Target.y);
  trace("");

  event.target.stopDrag ();
  event.target.removeEventListener (MouseEvent.MOUSE_UP, dropItem);
  event.target.addEventListener (MouseEvent.MOUSE_DOWN, dragItem);
  }

  }
  }

  My guess is you are trying to assign an event listener to an object that does not have one, an object bitmap, even if no error reported by you, I would hedge my bets.  If you place the image into a movieclip and set the event listener for the movieclip it might work... maybe something like...

  function loadComplete(event:Event):void {}
  var i: int

  var newMC:MovieClip = new MovieClip();

  newMC.addChild (event.target.content);

  testImageArray.push (addChild (newMC));

  I have = testImageArray.length;
  testImageArray [i - 1] .addEventListener (MouseEvent.MOUSE_DOWN, dragItem);

  testImageArray [i-1] .x = xPos;
  testImageArray there [i-1] = yPos;
  yPos += testImageArray [i-1] .height + 5;

  }

• [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.)

  }
  

  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.

• 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.

• Adding an event doubleclick on Graphic Image Online

  Hi all
  
  I am trying to add a doubleClickEvent to an InlineGraphicElement, so that a pop-up window appears and I can enter a new width and height. I have a problem adding a listener for the doubleClick event to an image I am about to add as a line chart. 1. before or after that I'm inserting the image with insertInlineGraphic(source,width,height), how can I add a double-click event listener? 2. once, I get a mouse doubleclick event works, how again can I access the selected or one doubleclicked image so I can change the width and height attributes?
  
  Thank you much for the help!

  We need expose the eventMirror property - it's a bug. I'll make the change today. Because there side effects I rename it to getEventMirror and it will no longer have a Get accessor.

• Problem with the event

  Hello
  I am facing a problem with the events. Please Ref. Event.zip the attachment.

  AEv.vi is a LV2G used for the reading/Generate/Init/destroy the event. Test2.VI is a main vi (we must run this vi)

  The AEv.vi Init action must be done in the other vi (other than the Test2.vi:- but for the objective test I've initialized in Test2.vi only).

  Test2.VI is used for genetate event.

  I could have called statically AEv.vi inside the Test2.vi to generate an event... but the path that comes is decided when running... (I have many live similar to AEv.vi...) .. who decided at run time...)

  The problem:

  When I run Test2.vi, it gives me the error code 1 (try running test2.VI... it gives the dialogue on the occurrence of the error)...

  Can someone fix this?

  Thank you!

  I modified your screws to do what I think you want.  The way you did the user events will not work.  I added a line to send orders to Ev.vi

• Q10 guest - zone problem blackBerry calendar event

  Hi all!

  I've just switched back to BlackBerry, iPhone and love everything about it so far except for one thing: calls on the calendar time zone problems.

  My work using an OS X hosted the CalDAV server, and I was able to sync my existing calendars to it without problem.

  My timezone: Eastern

  My colleagues timezone: Central

  Question: I received an invitation from a colleague, and on my Mac, it shows 13:00 Eastern, as it should.  The invitation has been sent to 12:00 Central.  This same invitation appears on my BlackBerry at 07:00 Eastern.

  Completed test:

  I added an invitation on my BlackBerry at 06:00 Eastern as a test and it appeared on my Mac at the right time without problem.

  I added an event on another day of my Mac, and it synced to my BlackBerry without problem.

  So it seems that my problem is that when the receiver event invites others, possibly in different time zones.

  My Mac and BlackBerry are both set to the Eastern time.

  My co-workers Mac and iPhone are set to Central time.

  I looked at all the parameters BB and can't find anything that would explain this strange behavior.

  I tried a battery pull - same results.

  I'm on the latest OS available for a Q10: 10.2.1.2976

  Can anyone help with this?  I'd hate to go back to iOS for a question like this, however, a precise and reliable timetable is essential for my work.

  Another update:

  Only, the lady came back on the line and told me that it is a known problem that is "actively investigated."  When asked how long their ticket has been opened on this subject, I was told since September of 2013...

  It seems that there is no resolution for this problem.  I will go back to iOS

• Global keyboard event listener?

  Is it possible to create a global keyboard event listener that is unrelated to a window, button, or other user interface element?  The best I could get to add the event to the window listener.  This only works if the window is active.  If the user clicks outside the window and then the receiver for the keyboard does not work.  In addition, when the dialog box appears first of all, it won't work until after the user has made some type of interaction with the window.  I want is to have keyboard shortcuts for users that work regardless of the place where they clicked on the screen, even if the dialogue window is not 'active'.  Is this possible?

  Here is the code I use to the receiver of keyboard for the window.

  mywindow.addEventListener ("keydown", function (k) {keyListen(k)});
  function keyListen(k){if(k.keyName=="Z"){alert("Do stuff here");}}
  

  I don't think that you can create listeners of world events, as for the first appearance of the dialog box, I solved this problem in my script: scripts buliarca BCM_ExtendShortcuts UI by a button activates the event listener to this button. A problem with attach listeners to window, it's in CC2015 events can only be attached to controls and not windows. Setting for windows works in CS6...

• Cannot add event listener to instantiated Movie Clip

  Hi guys,.

  I have a clip that I'm loading dynamically in my scene when a key is pressed.  Then, I would like to add a mouse event listener to the Movie Clip object so it can trigger a function when clicked.  I get an error when you try to do this and cannot find a solution anywhere.

  Here is my code:

  newLayerBT.addEventListener (MouseEvent.CLICK, newLayerBT_CLICK);

  function newLayerBT_CLICK (MouseEvent): void {}

  layerCount = layerCount + 1;

  Make a new object in my class BlankLayerMC

  var newLayer:BlankLayerMC = new BlankLayerMC;

  addChild (newLayer);

  Position the new object

  newLayer.y = prevY + newLayer.height;

  Change the text inside the object in order to take account layerCount courses

  newLayer.layerName.text = 'Layer' + layerCount;

  newLayer.layerNum = layerCount;

  prevY = newLayer.y;

  My problem occurs with this line...

  newLayer.addEventListener (MouseEvent.CLICK, moveSelection);

  layerArray.push (newLayer);

  }

  function moveSelection(e:MouseEvent):void {}

  var t = e.target;

  layerSelectedGraphic.x = t.x;

  t.y = layerSelectedGraphic.y;

  Any help would be greatly appreciated

  change:

• [noob] Possible to add an event listener in a table?

  Hi all

  I suspect, it might not be a way to do this, but I thought I would ask.

  I was wondering if there is anyway to add an event listener to a table ("array.addeventlistener (EVENT, cheetosFunction)');.

  I'm working on writing from a table that has several pushed DisplayObjects in, and I was hoping that instead of having to associate each DisplayObject instance with a listener event separately ("head.addEventListener [...], torso.addEventListener [...] legs.addEventListener [...]" ""), since the entire table would be these DisplayObjects, I could save time by adding a unique EventListener in the table, which has a single line of code instead of several.

  Any way to do this, or do something useful in the same way?

  use:

  for (var i: int = 0; i<>

  table [i] .addEventListener (MouseEvent.CLICK, cheetosFunction);

  }
