    TileList itemRender reorder

    Luis Pedro Ferreira

      Hi all.

      Hope you can help me on this, I'm sure lots of you already did what I'm trying to aim.

      Let's imagine a tileList like this:


      [ 0 ][ 1 ][ 2 ]

      [ 3 ][ 4 ][ 5 ]

      [ 6 ][ 7 ][ 8 ]


      Then I remove from the array the index 4. What I want to happen is when I remove the itemRender index 4, all the other itemRenders move left or right, up or down till they became in their new places. (hope you understand)


      I can't find any help or information about how to do this on internet, so if you know how to do it, please give me some clues.

      I read somewhere that there's a trick with 2 arrays but how does it wokrs??


      Hope one of you can help me with this.


      Thank you.

          This code answers your question:


          <?xml version="1.0" encoding="utf-8"?>
                import mx.collections.ArrayCollection;
                [Bindable] private var ac:ArrayCollection = 
                  new ArrayCollection(["0", "1", "2", "3", "4", "5", "6", "7", "8"]);
            <mx:TileList dataProvider="{ac}" columnCount="3" 
              rowCount="3" width="100" height="100"/>
            <mx:Button label="Remove 4" click="ac.removeItemAt(4);"/>

            Hi Gregory and thank you for your answer.

            Actualy it doesn't do what i'm trying to get. I know how to remove and add more itens either to an array, arrayCollection or even to a container.

            What I'm trying to get is an animation of the remaining indexes in the container when I add or remove an element.


            I read something about the event "itemschangeeffect" for the TileList on the mx components but does it realy works? cause I also read that Adobe remove that event from the component....
