Skinning MX components

You add skins to Adobe® Flex® components by using ActionScript classes, MXML components, and image files. Image files can contain JPEG, GIF, and PNG images or SWF files.

This topic describes the process for skinning MX components. These are typically components that use the Halo theme. For information about skinning Spark components, see Spark Skinning.

By default, MX components in a Flex 4 application use the Spark skin classes in the mx.skins.spark.* package. To use Halo skins, you can either apply the Halo theme to your application or set the compatibility-version compiler option to 3.0.0.
