CHAPTER 3

Flex 101: Step by Step

This chapter will walk you step by step through the process of

constructing

a Flex application. That starts with learning how

Flex works. Flex is an XML-based language that is compiled

into Flash applications. You can see the process portrayed

graphically in Figure 3-1.

Figure 3-1. The flow of Flex application building

Going

from the bottom left of Figure 3-1 to the top right, Flex

Builder 3 helps you write app.mxml, the Flex application. That

in turn is run through the MXML compiler that generates a

SWF file for the application. It also generates a temporary

HTML test page that hosts the SWF so that you can test it. The

SWF and the HTML are replaced after each compile, so I made

them dashed to indicate that they are temporary.
