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.

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....
