• Help needed to convert the ArrayList collection ArrayCollection

  
  I am converting an ArrayList (Java) to the collection of Flex ArrayCollection.
  Please help me in this, I don't know whether there is a correct approach

  I have a created a class user VO ActionScript Flex with two properties as uname, pass.

  [Bindable]

  With the code below, the DataGrid displays is empty without data, please help me where I am wrong doung

  I have to do something more? The data comes on the lcds Server console.

  Help, please.

  Hi Kiran,

  Try this once...

  private void displayDetails(event:ResultEvent):void
  {
  result = new collection ArrayCollection (event.result as Array);

  }

  Just try to debug by placing the stop point and make sure that you have found event.result as array... If not, then change your code accordingly.

  Thank you

• How to access the Flex collection ArrayCollection in Action Script components?

  I have this code-

  < mx:Label text = "Style" / >
  < mx:ComboBox id = "cboStyle" initialize = "{changeSkin('skins/Plain.swf') ;} "change ="{changeSkin (cboStyle.selectedItem.data) ;} ">
  < mx:ArrayCollection >
  < mx:Object label = "Plain" data="skins/Plain.swf"/ >
  < mx:Object label = "BlueTan" data="skins/BlueTan.swf"/ >
  < mx:Object label = "Brauwny" data="skins/Brauwny.swf"/ >
  < mx:Object label = "Darknite" data="skins/Darknite.swf"/ >
  < mx:Object label = "iCandy" data="skins/iCandy.swf"/ >
  < mx:Object label = "Minty" data="skins/Minty.swf"/ >
  < mx:Object label = "SimplicityGray" data="skins/SimplicityGray.swf"/ >
  < mx:Object label = "SummerSky" data="skins/SummerSky.swf"/ >
  < / mx:ArrayCollection >
  < / mx:ComboBox >

  I would like to do instead of initialize = "{changeSkin('skins/Plain.swf') ;} "East of refers to an item in the collection ArrayCollection.  How can I do this?  I'm relatively new to Flex.  I guess that there is a way to access the ArrayCollection collection and then access the individual table entry.

  Thank you

• Problems using collection ArrayCollection as a DataProvider for trees and the menu bar, possibly bug?

  Hi guys,.

  I'm having some troble using a collection ArrayCollection as a DataProvider for a tree and a menu bar...

  I read some Adobe documents on this subject, and I read that two components read the dataProvider in the same way.

  but my current works of DataProvider well on the tree, but not on the MenuBar component...

  My dataProvider is an ArrayCollection collection of a custom class (which extends from ArrayCollection collection), and among its assets is a children's collection: ArrayCollection, so the hierarchy can be read correctly.

  When I use the component of the tree it works, but the menu bar do not display the branches...

  Can someone help me?

  Here's the function that create my dataprovider:

  
  private function fnFillDP (): void {}
  for (var i: int = 0; admResult.length > i; i ++) {}
  If (.nivel JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]) == 0) {}
  var novoMenu:CL_ArrayMenu = new CL_ArrayMenu();
  novoMenu.idMenu = .idMenu JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenu.titulo = .titulo JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenu.parent = .parent JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenu.nivel = .nivel JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenu.ordem = .ordem JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  
  dataProvider.addItem (novoMenu);
  } ElseIf (.nivel JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]) == 1) {}
  for (var j: int = 0; dataProvider.length > j; j ++) {}
  {If (CL_ArrayMenu(dataProvider[j]).idMenu == {JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]) .parent})}
  var novoMenuChildren:CL_ArrayMenu = new CL_ArrayMenu();
  novoMenuChildren.idMenu = .idMenu JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenuChildren.titulo = .titulo JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenuChildren.parent = .parent JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenuChildren.nivel = .nivel JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  novoMenuChildren.ordem = .ordem JV_MenuAdm (JV_AuxMenuAdm(admResult[i]).menuAdm [0]);
  If (dp.length > 0) {}
  If (CL_ArrayMenu (dp.getItemAt (0)) .parent == novoMenuChildren.parent) {}
  dp.addItem (novoMenuChildren);
  } else {}
  DP = new ArrayCollection();
  dp.addItem (novoMenuChildren);
  }
  } else {}
  dp.addItem (novoMenuChildren);
  }
  
  CL_ArrayMenu (DataProvider [j]). Children = dp;
  break;
  }
  }
  }
  }
  tree.dataProvider = dataProvider;
  menu.dataProvider = dataProvider;
  }

  Sorry for the bad English...

  Hello

  You can try using xml as the dataprovider of the Menu bar instead of going for the Arraycollection collection.

  Thank you

• Display collection ArrayCollection in a list and the ArrayCollection with Drag and Drop collection reorgnize

  I have an ArrayCollection collection created like this

  qaAC = new ArrayCollection();

  for (var i: int = 0; i < 10; ++ i) {}
  var o: Object = {question: ' what is "+ i +"? ", answer:" it's "+ i"};
  qaAC.addItem (o);
  }

  The ArrayCollection collection is an array of object that has properties "question" and "answer to" custimized.

  I want to put 'issues' in the ArrayCollection collection in a list. 'qaAC.question' does not return an array of questions for me.

  I have to extract the ArrayCollection collection to form a new String table, and use the new array as the dataProvider of the list of questions.

  Is there a way better and clean?

  My goal is to use a list to reorgnize an ArrayCollection collection that contains complex objects (not simple string) with Drag & Drop. Is this possible?

  Any suggestions?

  I put two lists in my example to show how the ArrayCollection collection could be displayed in two different ways. You don't have to have two lists if you do not need them.

  When you change the order of the list made with drag and drop, you change the order of the collection ArrayCollection qaAC, so all the controls that display the qaAC will also be updated to reflect the new order. You can test this in the example I posted earlier. Change the order in the list of question and you will see the order change also in the list of responses. This is because they are both bound to the same collection of ArrayCollection. If you want to behave independently, you need two separate ArrayCollections.

• Problems on collection ArrayCollection and DataGrid

  Hi people!
  I have a problem of ugly...
  in the my application, I have a datagrid named DG and its dataprovider is bound as an ArrayCollection called AC collection.
  A result of the query contains the AC...
  
  Ok.. So far so good...
  
  the problem just when I try to select an object in AC by name...
  AC has done like this:
  0 objecthjh324jghf7
  1 objectd5674567
  2 objectAaagohrtt
  3 object4534c45jg
  
  so I can choose an object by its index (0,1,2,3... ecc)
  but not by name (objectxxxxxx)
  
  I might want the names of the objects are the name of the column (such as ID, NAME, NATION, phone ecc)
  
  is this possible?
  now, if I want the object ID in KT (i.e. the ID column in my datagrid DG), I have to check with a loop from 0 to col_number to find some AC (loop_value) USER.USER
  
  EDIT
  example:
  If my first column of the DG's 'id', I want to use something like "myDataGrid.columns ('id')", now I have to use this "myDataGrid.columns (0)»
  EDIT
  Help me please! : D :D

  try (somewhere in your result handler that takes care of your objects):

  var sampleObj:Object = myQuery [0];
  columnNames = []; should be set on a global scale
  for {(prop: String en sampleObj)}
  columnNames.push (prop);
  }

  now:

  public void hideColumns(columnsToHide:Array,_myDataGrid:DataGrid):void {}
  for (var x = 0; x)< columnstohide.length;="">
  myDataGrid.columns [columnNames.indexOf (columnsToHide [x])] .visible = false;
  }
  }

  Thanks in advance

  Hi anthony,.

  from the looks of it the collection ArrayCollection class is available only if you are coding in Flex (MXML). Since you only use ActionScript, you cannot use this class. Now depending on what you want to achieve with your application, there are different equivelents. on the fly, your best bet will be to use the DataProvider class in the catalog of QNX API:

  http://www.BlackBerry.com/developers/docs/airapi/1.0.0/QNX/UI/data/dataProvider.html

  hope that helps. Good luck!

• collection ArrayCollection collection arraycollection assigned values from the original setting?

  Hi... I am pretty stumped on this one. Here's the situation... on my main flex app I define an arraycollection collection:

  public var fiscalYrsArray:ArrayCollection;

  The collection is filled with the results of a query to a CFC

  protected function fiscalYrs_resultHandler(event:ResultEvent):void {}

  for (var x: int = 0; x < event.result.length; x ++) {}

  If (event.result [x]. DATA == passData.filterFiscalYrs) {}

  Event.Result [x]. Assigned = true;

  }

  }

  fiscalYrsArray = event.result as ArrayCollection collection;

  }

  I have a main application with drop-down menus window (I use a multi-case combobox). I use this window as a filter window, where users can choose what they want filtered.

  on this component, I use a temporary arraycollection collection (b/c I don't want to change the assignments of the arraycollection the temp collection is based off of) which will be a copy of the fiscalYrsArray of the parentApplication collection:

  " < = xmlns:fx s:TitleWindow ' http://ns.Adobe.com/MXML/2009 'close = "PopUpManager.removePopUp (this)'

  xmlns:s = "library://ns.adobe.com/flex/spark" title = "filter data" creationComplete = "initComp (); »

  xmlns:MX = "library://ns.adobe.com/flex/mx" width = "400" height = "300".

  xmlns:multiPickBox = "Components.multiPickBox. *" >

  < fx:Declarations >

  <! - Place non-visual elements (e.g., services, items of value) here - >

  < / fx:Declarations >

  < fx:Script >

  <! [CDATA]

  Import mx.collections.ArrayCollection;

  Import mx.controls.Alert;

  Import mx.managers.PopUpManager;

  private var tempfilterFiscalYrs:String

  [Bindable] private var fiscalYrDP:ArrayCollection = new ArrayCollection collection;

  private function initComp (): void {}

  fiscalYrDP = parentApplication.fiscalYrsArray;

  tempfilterFiscalYrs = parentApplication.passData.filterFiscalYrs;

  }

  protected function msc_addItemHandler(event:Event,filterVal:String,comboId:String):void

  {

  Alert.Show ("get here '");

  This [filterVal] = ";

  {for each (var point: Object in {this [comboId] .selectedItems)}

  This element of += [filterVal] ['DATA'] + ",";

  }

  filterChange = true;

  idText.text = str;

  }

  I am lie the collection arraycollection filterYrDP to a custom choice multi combobox:

  < multiPickBox:CheckCombo id = "fiscalYearF" width = "162" dataProvider = "{fiscalYrDP}".

  addItem = "msc_addItemHandler (event, 'tempfilterFiscalYrs', 'fiscalYearF')" "

  allIndex = '0' x = "77" y = "17" labelField = "DATA" / >

  However, I find that when an element is activated the assigned = true value is actually applied to the fiscalYrsArray of my parentApplication origin. I just want the assigned = true to apply to the fiscalYrDP collection arraycollection (one that is based on the fiscalYrsArray of parentApplication). How could it be written back and changing the properties of a fi main is just a temporary copy?

  By assigning the table using "=" you are just assigning the same table - in the same memory location.

  If you want to keep a separate table, you use the function ObjectUtil.copy

  import mx.utils.ObjectUtil;
  
  arrNewData  = new ArrayCollection();
  arrOldData  = ObjectUtil.copy(arrNewData) as ArrayCollection;
  

• Problem with allocating memory collection arraycollection by AddItem

  I have a strange problem with the AddItem method.

  I made a new item with this code:

  ------

  for (var u: int = 0; u < 41; u ++) {}
  Page = new PageToSave();
  project.addPage (page as PageToSave);
  }

  -----

  the project is a distance of class projectblueprint:

  package marcoDoItBetter.utils
  {
  Import mx.collections.ArrayCollection;
  public class ProjectBlueprint
  {
  private var _pages:ArrayCollection;

  public void addPage(page:PageToSave):void
  {
  This._pages. AddItem (page);
  }

  }

  }

  ----

  PageToSave is a class that extends the object.

  When we create the element using the addPages (so with in the collection _pages arraycollection's addItem) programmatically, we have this result using the term Inspector in debug mode.

  is a garbage collector from?

  How can we solve this problem?

  Thank you

  Hello

  From the looks of it, looks like a bug.

  Are you defining filters or performs a sort on the ArrayCollection collection? Or it's just a pure naked collection instance ArrayCollection.

  Have you tried addItemAt() and got the same result?

• How to browse the collection ArrayCollection?

  I have two datagrids and you want to move items on datagrip and fill the other.  Here is a screenshot of a Visual screen.

  

  In the screenshot on I can add some names/sex to the datagrid on the left using the text input and the Add button.  I can select the checkboxes for each name of ros as well. I want to do is move the check names in the datagrid control on the left for the datagrid on the right.  4 max.  But if I chose only 2 name, both names would be added to the 1 Racer and Racer 2. Runner 3 and 4 of the race would be left blank.  If I check the new names and submitted it would be in a new line on the left data grid.

  What I can understand is to scroll the datagrid control left and find only the lines of control.  To the right of the datagrid can be quite easily as soon as I figure out how to identify what is checked and what is not checked.

  This is the datagrid on the right.

  "" " < mx:DataGrid x ="10"y ="76"height ="337"id ="list"editable ="false"dataProvider =" rosterArray{}">

  < mx:columns >

  < mx:DataGridColumn headerText = "" width ="30">

  < mx:itemRenderer >

  < mx:Component >

  < mx:CheckBox / >

  < / mx:Component >

  < / mx:itemRenderer >

  < / mx:DataGridColumn >

  "" < mx:DataGridColumn headerText = "name" dataField ="name" width = "200" "editable ="false" / >

  "" < mx:DataGridColumn headerText = "sex" dataField ="sex" width = "40" "editable ="false" / >

  "" < mx:DataGridColumn headerText = "time" dataField ="time" width = "45" editable ="false" / >

  < / mx:columns >

  < / mx:DataGrid >

  The function add to my rosterArray (left datagrid) is below.

  private function rosterAdd():void

  {

  rosterArray.addItem({name:addName.text,sex:sexGroup.selectedValue.toString()});)

  addName.text = ""; empty text entry field.

  }

  I guess I have to scroll datagrid and not the rosterArray because I don't have a place for the checkmarks in the rosterArray.

  Any help idetifying which lines are checked in the left data grid would be much appreciated.

  Thank you.

• Collection ArrayCollection - summing values

  Hello

  In my application an ArrayCollection collection returns values such as '1', '2', '3' and so on. Now, I would like to sum 10 each so that the end result would be '10', '20', '30 '.

  How can I do that. I tried to find a way to convert them to numbers, but I don't know if this "possible.

• Impression of field collection ArrayCollection object

  Hi all

  I can return the collection of items in area code (POJO/value object) server that can be extracted as a collection table-side client in Flex. On the iteration of the table collection, we can get each item as an object. It is now possible to print/get the individual properties on object/POJO without creating/binding with action script class.

  For example a collection of used class has been removed from the side server, and we have in collection ArrayCollection. We can print the Rible properties such as first name, last name etc without creating a corrosponding action script class.

  Thank you

  Hello

  well, sure you can.

  As you mention all the object will be an object with all the properties type. Then simply to know the names of these properties.

  for each (var obj:Object in _arrayCollection)

  {

  trace (obj ["name"]);

  trace (obj ["name"]); and so on

  }

• Enter the filtered items in collection ArrayCollection after such FilterFunction

  It is an easy one. I have my filtering function, but rather than use main ArrayCollection collection after it has been filtered, I want to retrieve all filtered items and pass them in another collection ArrayCollection.

  private var allScreens:ArrayCollection;

  [Bindable]
  private var filteredScreens:ArrayCollection;

  private void filterFunc(value:Object):Object
  {
  If (Number (value.module_number) == 1)

  {
  Returns true;
  }
  Returns false;
  }

  
  private void filterSuff(value:Object=null):void
  {
  allScreens.filterFunction = filterFunc;
  allScreens.refresh ();
  
  for (var i: int = 0; i < allScreens.length; i ++)
  {
  If (allScreens.getItemAt (i) .module_number == 1) {}
  filteredScreens.addItem (allScreens.getItemAt (i) .filename);
  }
  }
  
  trace (ObjectUtil.toString (filteredScreens));
  }

  Hmm, addAll() is a function for the ArrayCollection with Flex SDK 3.3 collection, but I guess not in some versions.  A loop could perform the same function.

  var point: Object;

  for each (item in the original)

  {

  filtered.addItem (item);

  }

  Let me know if it does the trick.

  Context menu button is defined as:
  < mx:PopUpMenuButton id = "AddMenu' label = 'Add' dataProvider ="{protocolList}"= 'name' showRoot = labelField 'false' itemClick ="runAddMenu (event); "/ >
  
  Result handler is:
  [Bindable] private var protocolList: XML;
  private void gotIt(e:ResultEvent):void {}
  protocolList = new XML (e.result);
  }
  
  With this configuration the popup appears like:
  Add >

  Repeating values where I'm just a right menu.
  I do not use attributes but the node element value of data and that seems to be confusing.
  
  I thought that the difficulty it is to convert the XML data in an ArrayCollection collection, but I can't get this to work.
  
  Documentation and examples, I assumed it would be as simple as changing my result handler in order to:
  [Bindable] private var protocolList: ArrayCollection collection;
  private void gotIt(e:ResultEvent):void {}
  var temp: XML = new XML (e.result);
  protocolList = temp. Protocol.record;
  }
  
  Problem is that gives me a runtime error: unable to compel XMLList for collection ArrayCollection.
  
  For some reason any 'temp' Gets type XMLList and not XML and I couldn't find a way to do it in XML.
  
  I know that I can browse the xml tree and building the ArrayCollection collection, but it seems exaggerated as Flex should be able to do it for me.
  
  I'm something obvious overseeing here?

  Thank you, Tracy, but I ended up iterating over XML data to generate an array to use in the menu. I tried your suggestions before, but the result has always been a hierarchical menu, where it must be flat. Maybe a problem with the help of the element instead of attribute values.

  At the end of the day, it's really simple to do this way, here's my latest code that helps someone else:

  [Bindable] private var protocolList: Array;
  private void loadProtocolsComplete(e:ResultEvent):void {}
  var temp: XML = new XML (e.result);
  protocolList = new Array ({name: "Select", id:-1});
  for each {(var elem:XML in temp.record)
  protocolList.push ({name:elem.name, id:elem.id});})
  }
  addMenu.dataProvider = protocolList;
  }

• Collection ArrayCollection clone

  [Salvation all THE]
  
  I decided to create a new topic for a problem in another... never mind: P
  
  Simple question
  
  I had a myOriginal (collection ArrayCollection), clone/where you want it and call the new: myCloned (collection ArrayCollection).
  
  myOriginal cannot be updated any more.
  
  This is my code so far but it stills updated the original Collection. I prove that by the loop and the trace of the original Collection.
  
  
  [Bindable] private var myData:ArrayCollection;
  [Bindable] private var myCloned:ArrayCollection;
  
  private void resultHandler(event:ResultEvent):void {}
  myData = event.result.db.data; Original data
  cloneOriginal(); Perform cloning
  myData.disableAutoUpdate (); It is wrong... in the 'core' still updates... I think so..
  }
  
  
  private function cloneOriginal (): void {}
  var myCloned:ArrayCollection = new ArrayCollection();
  for (var c:int = 0; c < myData.length; c ++) {}
  myCloned.addItem (myData [c]);
  }
  
  
  Thanks in advance... ;)
  Base on...

  Thank you for using Clara, after some time, I've done the correction :)

  Final code, thanks to anyone are [[]]:

  "- How do I clone an ArrayCollection collection.

  Import mx.utils.UIDUtil;
  Import mx.collections.ArrayCollection;
  Import mx.rpc.events.ResultEvent;

  [Bindable] public var myOriginal:ArrayCollection;
  [Bindable] public var myCloned:ArrayCollection = new ArrayCollection();

  FLEX THINGS...
  public void objectCopier(toAdd:Object):Object {}
  var addME:Object = clone (n);
  addME.mx_internal_uid = UIDUtil.createUID ();
  return Alain;
  }

  public void clone(source:Object): * {}
  var myBA:ByteArray = new ByteArray();
  myBA.writeObject (source);
  myBA.position = 0;
  Return myBA.readObject ();
  }
  END

  public void resultHandler(event:ResultEvent):void {/ / result of a HTTPService...} For example, of course...
  myOriginal = event.result.db.data;
  myCloned = clone (myOriginal); THE ACTION IS HERE

  hList.dataProvider = myOriginal; Stay forever with these data
  hList2.dataProvider = myCloned; Table working on it
  }
