32 Introducing Flex

Repeaters Repeaters let you dynamically repeat any number of controls or

containers specified in MXML tags, at runtime.

For more information, see Chapter 26, “Dynamically Repeating

Controls and Containers,” in the Flex 2 Developer’s Guide.

Image and media

importing

You can use MXML tags to import several images into

applications. Flex supports several formats, including JPEG,

PNG, GIF, and SVG images and SWF files. In addition, you can

use the VideoDisplay control to incorporate streaming media into

Flex applications. Flex supports the Flash Video File (FLV) file

format with this control.

For more information, see Chapter 30, “Embedding Assets,” in

the Flex 2 Developer’s Guide.

View states View states let you structure your application to present a varying

appearance by defining a base application view state, and sets of

changes that modify the base view state. Each view state can

add or remove children, set or change styles and properties, or

define state-specific event handlers. You can also define

transitions between view states, which control the appearance of

the change from one view state to another.

For more information, see Chapter 27, “Using View States,” in

the Flex 2 Developer’s Guide.

ActionScript scripting 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 9, “Code Editing in Flex

Builder,” in Using Flex Builder 2, or Chapter 4, “Using

ActionScript,” in the Flex 2 Developer’s Guide.

Debugging 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 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.
