Description
Behaviors let you add animation or sound to applications in response to
user or programmatic action.
For more information, see Chapter 21, "Using Behaviors," in Developing
Flex Applications.
Repeaters let you dynamically repeat any number of controls or
containers specified in MXML tags, at runtime.
For more information, see Chapter 8, "Dynamically Repeating Controls
and Containers," in Developing Flex Applications.
Flex supports several formats, including JPEG, PNG, GIF, and SVG
images and SWF files. In addition, you can use the MediaDisplay,
MediaController, and MediaPlayback controls to incorporate streaming
media into Flex applications. Flex supports the Flash Video File (FLV)
and MP3 file formats with these controls.
For more information, see Chapter 13, "Importing Images," in
Developing Flex Applications.
Deferred instantiation lets you determine when controls and other
components are created when you invoke a Flex application.
For more information, see Chapter 27, "Improving Layout
Performance," in Developing Flex Applications.
You can use the Flex JSP tag library to add MXML code to your JSPs
or create custom HTML wrappers for your Flex applications.
For more information, see Chapter 38, "Using the Flex JSP Tag
Library," in Developing Flex Applications.
ActionScript lets you perform actions with the components that are
represented by MXML tags. You use ActionScript in your Flex
applications to do the following:
• Handle events
• Define custom functions and methods
• Call ActionScript functions
• Work with components after they are instantiated
For more information, see Chapter 16, "Working with ActionScript in
Flex," in Developing Flex Applications.
Flex includes support for debugging and warning messages, an error-
reporting mechanism, and a command-line ActionScript debugger to
assist you in debugging your application.
For more information, see Chapter 36, "Debugging Flex Applications,"
in Developing Flex Applications.
