Chapter 3: Creating, Coding, And Debugging Flex Files; Creating Mxml Or Actionscript Files - MACROMEDIA FLEX BUILDER-USING FLEX BUILDER Use Manual

Creating, Coding, and Debugging Flex Files
Macromedia Flex applications are made up of plain text files containing MXML and ActionScript
code, plus assets such as Flash components (SWC files) and images. The Flex server compiles the
MXML and ActionScript files into Macromedia Flash SWF files that can run in Macromedia
Flash Player or in a web browser with Flash Player installed.
Macromedia Flex Builder provides you with an integrated development environment for writing,
editing, debugging, previewing, and deploying MXML and ActionScript files.
