How to make a table grid in Flex 4?

I want to make a grid with 3 images in a row and then should the next row start. How do I that in Flex 4? Are there any controls or can you do it with the Repeat开发者_Python百科er? Or am I forced to do some math on my own (modulus here we go again).

You may use a TileLayout:

<s:DataGroup>
    <s:layout>
        <s:TileLayout />
    </s:layout>
</s:DataGroup>

When a line is full, it goes to the next line automatically.

You could use a TileList and set the columnCount property = 3.

Example:

<?xml version="1.0" encoding="utf-8"?>
