70 Building a Flex Application
Using Flex development tools
Flex provides the following tools to help you test, debug, and tune your applications during
the development process. The following table describes the Flex development tools:
Tool Description
Flex Builder Flex Builder is an integrated development environment (IDE) for
developing applications using the Flex 2 SDK. The Flex Builder
IDE provides tools that help you develop, design, and debug Flex
applications, including an integrated incremental compiler and a
step-through debugger.
For more information, see Using Flex Builder 2.
Flash Debug Player Flash Debug Player is a Flash Player that reports runtime errors,
including errors for undeclared variables, uncaught runtime
exceptions, and operating-system–specific networking errors. You
can view errors in a trace window and send errors to a text file.
For more information, see Chapter 11, “Running and Debugging
Applications,” in Using Flex Builder 2, or Chapter 12, “Using the
Command-Line Debugger,” in Building and Deploying Flex 2
Applications.
Command-line debugger The Flex ActionScript debugger lets you open and debug
ActionScript files that your Flex applications use. You can use the
debugger from Flex Builder, or from a command line.
For more information, see Chapter 11, “Running and Debugging
Applications,” in Using Flex Builder 2, or Chapter 12, “Using the
Command-Line Debugger,” in Building and Deploying Flex 2
Applications.
mxmlc The Flex command-line compiler, mxmlc, is useful if you want to
request SWF files in a web browser or in Flash Player. It is
particularly useful for debugging SWF files with Flash Debug
Player.
For more information, see Chapter 11, “Running and Debugging
Applications,” in Using Flex Builder 2, or Chapter 9, “Using the
Flex Compilers,” in the Flex 2 Developer’s Guide.
compc The compc compiler generates a SWC file from MXML
component source files or ActionScript component source files.
For more information, see Chapter 9, “Using the Flex Compilers,”
in Building and Deploying Flex 2 Applications
, and Chapter 10,
“Building Projects,” in Using Flex Builder 2.
