A TileList is part of a group of elements that allow you to add components in a specific order and orientation. The TileList controls the displaying of a number of items set out as tiles and so it best suited to displaying images as thumbnails.

There are many ways to do this, but none of the examples on the Flex site seemed to be very useful, or very well explained. What I wanted to do was to create a TileList that displayed the tiles in a certain way and used an XML file to fill up the list of items with images, each image having a label associated with it.

Yesterday I talked about creating some simple Flex elements in your application. Today I will introduce a new element called Script.

The Script element, if you haven't already guessed is used to run your application function and should be contained within the Application element. You can either put script inline like this.

Flex is a powerful SDK that allows you to build Flash applications that can then be embedded into any web page. The SDK is that Flex uses quite large and covers a whole range of things from interface controls to data processing. To program in Flex you need to use ActionScript 3. What Flex creates as output is swf files, which can be run separately or embedded into a web page.
