Now we’re ready to create the Tile component in MXML, bind

the photoFeed XML data to the TileList component, and then

create the thumbnails item renderer in the Tile component:

1. We will use a TileList component to display the images.

After the HBox component and before the closing Appli

cation tag, add a TileList component with a width of

100% and a height of 100%. This TileList is shown in

Example 3-11.

Example 3-11. The TileList

<mx:TileList width="100%" height="100%">

</mx:TileList>

2. Using the Outline view, locate the TileList component

and add an attribute of dataProvider with a value of

{photoFeed} to bind the data to the tile component. (Re-

member to move the > to the end of the dataProvider

line.) Example 3-12 shows the completed TileList com-

ponent.

Example 3-12. The completed TileList

<mx:TileList width="100%" height="100%"

dataProvider="{photoFeed}">

</mx:TileList>

3. The item renderer renders the layout for each item in the

TileList. Within the TileList component, add an item

Renderer property, using the code shown in Exam-

ple 3-13.
