  You seem to have two problems here and are confusing them.  You must break the problem into two parts

  (1) extract the data from the entry and create the objects you want to display

  2) display in a list, a set of objects.

  Let's get the sorted first premiera.

  I will suggest what to do here, but in practice, you might actually think about this yourself as part of the design phase of your application.  You should do this, not me, because then you will have all the information available.  At the present time, I have just what you said, which is not much.  So maybe what I'm telling you is not correct for your application.  Only you can decide that.  And be blunt here, you should have decided this before you start coding.  Do you want you could lead down the wrong path.  You must think of your application as a home - as the architect must design all the rooms, and how they will be built, before you start building the House.  You do not, then we are building the rooms on the fly.  Who knows if they will be fit at home?

  In this case, I think you need to create an object that represents each of the elements in the internal array of new data.  call this object

  NewsItem

  This object will have attributes, such as its title, content, date, the linked image and so on, each of whom have will get and set methods.  While you treat each inner element fetch you the associated entry and update the object.

  When you have finished the inner loop of processing, you now have a complete

  NewsItem

  Object, so you will add it to a collection, an array of NewsItem objects, call this _newsItems.  You will create it at the beginning - you know how many entries it takes because it is the number of entries in your outdoor table.

  So before you start to deal with JSON, create your table and the 'index' value of 0.

  Once you have created your Newsitem, add this in the table to the position 'index' and increment "index".

  And once you have analyzed all the JSON, you will have a complete picture.  This is part 1 finished!

  And note in your drawListRow, you are given a clue - that is the index in your tables in _newsItems.  So you can easily find which entry to view and display it correctly.  But it is part 2 and is a separate issue.

• Cannot focus on the custom itemRenderer?

  I made a custom itemRenderer double as an itemEditor following the instructions in the documentation.
  However, even if I put the rendererIsEditor = "true", when tabbing between other editable fields, controls within the itemRenderer do not receive focus. I can't help thinking it of a control/bug, but is it possible to submeter the itemRenderer to focus properly? At the moment my component is simply a box inside an HBox.
  
  Anyway, here is my code so that you can see for yourself (I have included a checkbox as itemRenderer so that you can see the * desired * effect.)

  < mx:DataGridColumn dataField = "num" headerText = "num" editable = "true" / >
  < / mx:columns >
  < / mx:DataGrid >
  < / mx:Application >
  

  Too bad... I found the answer to a few pages later in the docs...
  You must implement the IFocusManagerComponent interface and then substitute drawFocus as below to set the focus to the checkbox... hope it works for multiple controls.

  
  
  override public function drawFocus(focused:Boolean):void {}
  check.setFocus ();
  }

• Move the focus of the custom button

  Hello

  My button did to paint two differrent bitmap:

  Paint (Graphics g)

  {

  g.isDrawingStyleSet (Graphics.DRAWSTYLE_FOCUS)? FOCUS: NORMAL;

  g.drawBitmap (0, 0, getPreferredWidth(), getPreferredHeight(), _bitmaps [index], 0, 0);

  ...

  }

  How do I call it g.setDrawingStyleSet (Graphics.DRAWSTYLE_FOCUS, false) to navigationUnclick (State of the int, int hour). To make the button unfocus after a click.

  removeFocus() didn't work?

  clues will be a great help.

  This will work as long as the button is focused. You can add a custom boolean to change the drawing, or move the focus to another field.

• How to manage the focus in the custom component

  Hallo. As you know some flex components have indigenous focus, like buttons, textinput, etc... I created a custom component which is a borderContainer... As you know, by default, if the user press TAB my BorderContainer will never receive the focus... I tryied to set a property as setFocus() and tabFobusEnabled to true, but I still have some problems with my borderContainer development... It's as if my app knows that my custom component is not a native component... Is there a way for my component to receive focus without problems?... Which is the best way to do this?

  Thx a lot

  Max

  Components must implement IFocusManagerComponent in order to receive the focus.

• Clear link to the customer list

  Kind of goofy question - how can I clear the list of VC servers and hosts that your client is connected to?  On mine there is a bunch of connections unique to the guests, as well as tips from the lab that doesn't exist anymore - more than 40 points in total!

  I guess that's in a file on my PC, but I can't.

• Accessing the context property of main.qml to a custom list in a file item separate qml

  Hi all

  Sorry if this is already covered somewhere.

  I currently have an application with a list view in my main.qml.  I put a context property for my class app c ++ to be "app" in my main.qml.  My list uses a custom list item that is defined in a file separate qml.  The custom list item has a popup menu.  In this context menu, I want to call Q_INVOKABLE functions that are part of my class from the main application in C++.  What is the best way to be able to do?  Should I just set the context property on my file qml of list item custom like I do with my main.qml or is there a better way?

  Thank you

  I think that this has been repeated several times, but as it is not really intuitive:
  a listitemcomponent lies in a different context, it cannot access the context property of the qml file.
  You can use the reference to the listview to reach outside, see https://developer.blackberry.com/cascades/reference/bb__cascades__listview.html ListItem.view

• The Custom Format recording

  Hi all

  I'm looking how to save a document in a custom format.

  When registering a .tga I use:

  PSapp.ActiveDocument.SaveAs (output, tgaSaveOptions, psExtensionType.psLowercase, false);

  What I want is to save in a customized format that is not in the list of available SaveOptions.

  The format I want to save is a specific .tga: NW4C_TGA (file owner format) there several options specific to the economy of this format.

  When I save a file by hand in the display save as Photoshop dialog box, it displays the custom list format and I can select and configure the options.

  It's because I put the NW4C_Tga.8bi file in the directory of Plug-ins for photoshop.

  How can I access these custom by the script format?

  Thank you very much for your attention.

  Jeff

  You must install the plugin scriptlistner and see if it creates a code when you save in this format.

• How to determine if the rank of the acquired list focus?

  Hi all

  I have ListField with custom reminder.

  When the user change focus by the movement of the navigation, drawListRow() is called several times - for each focus-changed event.

  How can I determine in the method drawListRow() if current rank on the FOCUS_GAINED event?

  I can do that by following the path:

  public void focusChanged( Field field, int eventType )    {        mIsFocusGained = false;
  
          if( eventType == FOCUS_GAINED )        {            mIsFocusGained = true;        }    }
  
   public void drawListRow( ListField listField, Graphics graphics, int index, int y, int width )    {        int rowHeight = listField.getRowHeight();        int selectedIndex = getSelectedIndex();
  
          if( index == selectedIndex && mIsFocusGained )        {            drawHighlightRegion( graphics, HIGHLIGHT_FOCUS, true, 0, y, width, rowHeight );        }---------
  

  But I can do that directly in drawListRow()?

  Thank you

  I expected allows you to change your listener to update as follows:

  if ( eventType == FOCUS_GAINED )
  {
  mIsFocusGained = true;
  }
  else
  if ( eventType == FOCUS_LOST )
  {
  mIsFocusGained = false;
  }
  

  I think you should ignore FOCUS_CHANGED because the listField stil keep focus in these events.

  I'm not clear on what you mean by that:

  "is that a function is to determine/get current theme ceremony?

  I thought you did that with your FocusChange listener?

• How long does it take for the custom field created in SFDC appears in the list of field mapping?

  How long does it take for the custom field created in SFDC appears in the list of field mapping? I hit the refresh field button, but it does not appear after 5 min. I just need to have patience?

  I had the same problem yesterday, I think it took about 10-15 minutes to appear.
