Access to the objects in the display list

• RemovePopUp method removes the object from the display list?

  I'm setting up an AIR application that uses several pop-up windows, and I get as much memory as possible windows pop up closed at each Garbage Collection.  Reading through forums / Articles / documentation, I see instances of object created by pop ups stay in memory (No GC would be) up to:

  -all references to the object are = null (cancelled)

  -all receivers on the object are removed (or are weakly referenced)

  -l' object is removed from the display list.

  My question is:

  Does

  PopUpManager.removePopUp (this);

  remove the object from the display list?

  I use PopUpManager.createPopUp () to instantiate a container to display mx:TitleWindow objects.

  The pop-up closed deletion function, however, I'm not sure if it is 'removed from the display list' completely.

  A simple answer is the best, what moves me in the direction of answering the question. (Also useful: How can I see the objects in the display list at a certain point during execution of the application?)

  Thank you all!

  He,

  Yes, removePopUp removes it from the display list.

• Is it possible to use the getObjectsUnderPoint of a DisplayObject that is not added to the display list?

  My situation:

  I have a DisplayObject (objA) added to the display list and a DisplayObjectContainer (objB) not added to the display list. When objA receives a MouseEvent.CLICK event, is it possible to use the localX and localY to the event of objA to get objects under the same point in objB?

  Sample:

  var objA:Sprite = new Sprite();

  objA.graphics.beginFill (0);

  objA.graphics.drawRect (0, 0, 100, 100);

  objA.graphics.endFill ();

  addChild (objA);

  var objB:Sprite = new Sprite();

  var childA:TextField = new TextField();

  childA.text = "This is the child.";

  objB.addChild (childA);

  objA.addEventListener (MouseEvent.CLICK, handlerClick);

  function handlerClick(e:MouseEvent):void {}

  var pt:Point = new Point (e.localX, e.localY);

  var objs:Array = objB.getObjectsUnderPoint (pt);

  trace (objs. Length);

  }

  so your test/trace environment can deliver it.

  Use the following code, publish your swf file and test the swf file in your standalone player (or publish a html and swf and test it in your browser).

  package {}

  import flash.display.Sprite;

  import flash.events.MouseEvent;

  to import flash.geom.Point;

  import flash.text.TextField;

  SerializableAttribute public class extends Sprite {Main2

  private var _objA:Sprite = new Sprite();

  private var _objB:Sprite = new Sprite();

  private var childA:TextField

  public void Main2() {}

  _objA.name = "a";

  _objA.Graphics.beginFill (0xdddddd);

  _objA.Graphics.drawRect (0, 0, 100, 100);

  _objA.Graphics.endFill ();

  addChild (_objA);

  _objB.name = 'B ';.

  _objB.Graphics.beginFill (0xdd0000);

  _objB.Graphics.drawRect (0, 0, 100, 100);

  _objB.Graphics.endFill ();

  _objA.addEventListener (MouseEvent.CLICK, handlerClick);

  Stéphane = new TextField();

  childA.name = 'tf ';

  _objA.addChild (childA);

  childA.multiline = true;

  }

  private void handlerClick(e:MouseEvent):void {}

  var pt:Point = new Point (e.localX, e.localY);

  var objs:Array = _objB.getObjectsUnderPoint (pt);

  childA.text = "";

  for (var i: int = 0; i

  childA.appendText(objs[i].name+"\n");

  }

  }

  }

  }

• Simple class and the display list

  I have a very simple code for a class:

  package
  {
  import flash.text.TextField;
  import flash.display.Sprite;
  
  SerializableAttribute public class Greeter extends Sprite
  {
  public void Greeter()
  {
  var txtHello:TextField = new TextField();
  txtHello.text = "Hello World";
  trace ("HI");
  addChild (txtHello);
  }
  }
  }

  The above file is saved as Greeter.as say folder C:\test

  I then create a Fla file, named test_display.fla (recorded in C:\test) and its content is:

  import Greeter;
  var tt:Greeter = new Greeter();

  Now, the output window displays salvation because of the trace statement but should show the addChild method

  Hello World in the Flash movie, but it does not work. The only way to get Hello World to the Flash movie

  is to change the test_display.fla to:

  import Greeter;
  var tt:Greeter = new Greeter();

  addChild (tt);

  In other words, I have to use the method addChild twice (once in the Greeter.as and once in test_display.fla)

  to get the Hello World to be displayed in the Flash animation. Does anyone know why this is so?

  Because each DisplayObject must be explicitly added to the display list. Text field is on the display of the banner of host list and in order for him show that he has relatives (Greeter) should be added to the other display list-timeline in this case).

  In other words, it is insufficient to simply create an instance - it must be added via addChild. It begins to make more sense if you remember that not all classes are DisaplayObjects and can perform other that just display objects functions.

• hard to follow the point at the top of the display list

  Hey there.

  All day yesterday I tried to find a way to do something and I finally gave! I hope you can help me!

  I have a folder that contains all the code for a main menu. This code shows how to load the other as a file which initializes the code for general items that will be on the scene throughout the entire flash.

  But when I initialize the code for one of the menu items when he clicks on I don't know how to get 2 of the elements from the code of scene elements to be at the top of the display list. Because, as the code for the menu item load the elements of two stages will cover the elements of this code and after loading his will open and show them things that are loaded from the menu item code.

  If you do not understand quite what I said here pls let me know if I can explain in more detail.   I appreciate any help or instructions that you can give me!

  As you know, we use to define the depths with swapDepths() within the AS2.

  In AS3 the setChildIndex allows you to set the depths of your symbol (s).

  send to back

  setChildIndex(myMC,0);

  bring to front

  setChildIndex (myMC, numChildren - 1);

  So if you have 3 clips (myMC1, myMC2 myMC3) and you want them to appear in this order of depth, simple call them in that order.

  setChildIndex (myMC1, numChildren - 1);
  setChildIndex (myMC2, numChildren - 1);
  setChildIndex (myMC3, numChildren - 1);

  I'm sure that you must use the setChildIndex() within the display object container class.

  http://www.Adobe.com/LiveDocs/Flash/9.0/ActionScriptLangRefV3/Flash/display/DisplayObjectC ontainer.html#setChildIndex%28%29

  I hope this helps?

  Anyone else want to add to this answer more in detail?

• ItemRenderer for access in the spark list

  Hello

  I have a list with itemRenderers generated dynamically depending on the types of items (as a Manager who has a kind of rendering engine and the other type of employees has other types of converters). I would like to access the itemRenderer for 'selectedItem' of the list manager, but the selectedItem(item:Object) has direct access to the data item, not its rendering engine.

  I prefer to dissociate the issue of its rendering engine as much as possible.

  Sorry if this is considered to be a station of the cross as I noticed a similar to stackoverflow post. But he doesn't seem to get all the answers so far. Thank you.

  In Flex, a data element is not directly mapped a specific converter.  It's because of virtual layout converter and recycling section.  If the data element is not in sight so it will probably not a rendering that are associated with engine and it is possible for a single data item to be pushed in the instances of the rendering engine different during its lifetime (for example when scrolling of the list).  In spark's best practice is to change the data item and design your converter to detect and react to these changes, rather than interacting directly with the instance of the rendering engine.

  Check out the spec of virtualization of spark for more information on the virtual presentation and rendering recycling: http://opensource.adobe.com/wiki/display/flexsdk/Spark+Virtualization

  If you really don't want to have access to instances of the renderer you still can, but you should be only after that you have a really good understanding of what is happening.

  Here is an example, you can use the method getElementAt() of the part of skin of the dataGroup list:

  http://ns.Adobe.com/MXML/2009.
  xmlns:s = "library://ns.adobe.com/flex/spark" creationComplete = "traceRenderers ()" > "
     
          private function traceRenderers (): void {}
  for (var i: int = 0; i< list1.datagroup.numelements;="">
  trace (List1.dataGroup.getElementAt (i));
  }
  ]]>
     
     
     
         
             
                 
  [0,1,2,3,4,5,6,7,8,9,10,11,12,13]
                 
             
         
     
  

• Help remove events on a part of the display list

  Hey all
  
  Basically, I'm looking for a 'switch' that I can use for valves of all events for a display object and all of its descendants in the Flash display list / scene graph.
  
  I have a display object with a good number of descendants who have various Auditors/managers MouseEvent assigned to them. I would like to be able to remove/disable all these events related to mouse (or just all types of events so it's easier) at some point in time without knowing the number of descendants or how much and what type of event listeners were recorded with each node.
  
  So apart from writing a method of removal of single event for each node and market then the list display, call this method for each node, how do I? Pixelation this object to a Bitmap object, and then exchange the two in the list view to get a version of 'static' with none of the managers is a work-around I don't really want to do either (sorry).
  
  any ideas?
  

  For mouse events, perhaps a combination of
  DisplayObjectContainer.mouseChildren and InteractiveObject.mouseEnabled

• Most of the OAMessageChoice list

  Hello world
  
  I have a big problem with the display list of the choice of the message in the OPS, first the messagechoice empty sound, when a settings conclude of the PFR, the AM method fills the VO, then in the PR messagechoice with the VO asociates, but cams them problem when the load of choice of message as the 'select from' list without where clause... How can I load the messagechoice forcing the where clause
  Here is my code
  
  This is the code of the PFR
  
  This sound event to grab the parameter and save it in a global variable
  {if (PageContext.GetParameter (EVENT_PARAM). (Equals ("FAM"))}
  String cveFam = pageContext.getParameter ("IdCatFams");
  AM. TRANS = true;
  AM.fam = cveFam;
  
  }
  
  in the PR charge parameter then calls the method AM and asociate the choice of the message and the VO
  
  / * METHOD to populate the LIST of POPS (select drop-down list)
  */
  If (am.fam! = null & & am.trans! = false) {}
  JEM OAMessageStyledTextBean = (OAMessageStyledTextBean) webBean.findChildRecursive ("tituFamTX");
  String m = pageContext.getParameter ("NomDeFam");
  mje.setText (m);
  String cveFam = am.fam;
  am.invokeMethod ("cargarActivos", new Serializable [] {cveFam});
  Choice of OAMessageChoiceBean = (OAMessageChoiceBean) webBean.findChildRecursive ("popList");
  choice.setPickListCacheEnabled (false);
  choice.setPickListViewUsageName ("ActivosPopListVO1");
  choice.setListDisplayAttribute ("description");
  choice.setListValueAttribute ("ClaveActivo");
  
  }
  
  and the code for the AM method:
  / * Method load dropdown
  @param familiaID
  */
  {} public void cargarActivos (String familiaID)
  If (familiaID! = null)
  FAM = familiaID;
  getActivosPopListVO1 () .setWhereClause ("ID_CATALOGO_FAMILIAS =" + fam);
  getActivosPopListVO1 () .executeQuery ();
  }
  
  Published by: mentor on 26/08/2010 15:10

  Mentor,

  How you bind parameter to the query is not a standard approach.

  Use the code below in your AM method:

  {} public void cargarActivos (String familiaID)
  If (familiaID! = null)
  FAM = familiaID;
  getActivosPopListVO1 () .setWhereClause ("ID_CATALOGO_FAMILIAS =: 1");
  getActivosPopListVO1 () .setWhereClauseParams (null);
  getActivosPopListVO1 (.setWhereClauseParam(0,fam));
  getActivosPopListVO1 () .executeQuery ();
  }

  This should solve your problem.

• Want to access a SOAP service and display the data in the external list

  Hello

  I could see a WCF Service via the type of external content successfully. Now I want to access a SOAP Service and display the data in an external list in Sharepoint 2010. I am able to create a data source with success with the SOAP service, but how to display the data in the external list as external list uses only as data sources for external content types.

  Also with WCF as external content type, it is only on WCF services or any kind of web services can be added as an external content type.

  Any help would be appreciated.

  Thanks in advance

• Access to the value displayed in the selection list

  Hello
  On a form, I have a select list (drop-down list).
  I can access the value selected in the help: syntax SelectListName.
  But how to get the displayed value?
  
  Thanks in advance,
  Alex

  If necessary in a PL/SQL environment (or I guess you can call AJAX then PL/SQL javascript) you can use these two APIs to help you perhaps?

  APEX_ITEM. TEXT_FROM_LOV
  APEX_ITEM. TEXT_FROM_LOV_QUERY

  Or should give you the value displayed for a corresponding return value (so since you can access the return value already, switch to one of these functions (as appropriate to your situation)).

• To access the display object on the stage of another class

  I Googled that nothing helps, I only found how to manipulate the scene itself and not a display on that object and I'm noob enough to not be able to figure it out from there. :/

  I have a clip on the main timeline with the instance name displayName. I created a button that should change this framework displayName will to (in order to... makes you guess? display the name of the button.) Awesome. )

  So, I'm trying to write the code in a reusable manner and have everything related to a class called GeoPuzzle buttons. Inside the GeoPuzzle I instantiate a touch event and run code. However, the function should be able to change displayName in the main part of the timeline and, of course, the compiler says displayName does not exist because I'm in a class and I don't mean the scene.

  Here's the code simplified in the class:

  package com.freerangeeggheads.puzzleography {}
  import flash.display.MovieClip;
  import flash.events.TouchEvent;
  
  SerializableAttribute public class extends MovieClip {} GeoPuzzle
  declaring variables
  
  public void setInitial (abbrev:String, fullName:String, isLocked:Boolean): void {}
  Set the parameters
  this.addEventListener (TouchEvent.TOUCH_BEGIN, geoTouchBeginHandler);
  }
  
  public void GeoPuzzle (): void {}
  }
  
  public void geoTouchBeginHandler (e:TouchEvent): void {}
  e.target.addEventListener (TouchEvent.TOUCH_END, geoTouchEndHandler);
  other methods
  nameDisplay.gotoAndStop (e.target.abbrev);
  }
  
  public void geoTouchEndHandler (e:TouchEvent): void {}
  other methods
  nameDisplay.gotoAndStop ("USA");
  }
  }
  }
  

  The lines in bold are my problem. Now this code does not actually as it is the case if you find an error in it, Yes, I have no idea what the problem is, but he DID run forward and these lines always gave me wrong so I'll try to help out on multiple fronts.

  How can I say displayName to change its current image within the display object class?

  Thank you!

  any display list object can refer to any display list object, but this is not necessarily good OOP.

  in any case, for your class reference displayName:

  . DisplayName MovieClip (this.parent)
