About the included theme files

Flex includes several themes that you can use without making any changes. With the exception of the default Halo theme, all of these themes are located in the flex_install_dir/frameworks/themes directory for the SDK. For Flex Data Services, the themes are located in the flex_install_dir/flex_sdk_2/frameworks/themes directory. For Flex Builder, the themes are located in the flex_install_dir/Flex SDK 2/frameworks/themes directory.

The following table describes these themes:

Theme	Description
Aeon Graphical	Contains the AeonGraphical.css file and the AeonGraphical.swf file. This is the graphical version of the default Halo theme, which is defined by the defaults.css file and graphical assets inside the framework.swc file. The source FLA file for the graphical assets is in the AeonGraphical Source directory. You change the graphical assets in this file by using the Flash IDE. You must ensure that you export the SWF file, which is used by the theme in Flex. This theme is provided as a starting point for graphically reskinning your application. While it might be more efficient, you lose some ability to apply run-time styles if you use it.
Halo	Provides the default Flex look and feel. The Halo theme uses the defaults.css file in the framework.swc file and the classes in the mx.skins.halo package. This is the default theme. For more information about the default theme assets, see About the default style sheet.
HaloClassic	Provides the look and feel of previous versions of Flex. This theme comprises the haloclassic.swc file. Included in this file are the CSS file and SWF file that provide graphical assets.
Ice	Contains the Ice.css file.
Institutional	Contains the Institutional.css file.
Smoke	Contains the Smoke.css file and a background JPEG file.
Wooden	Contains the Wooden.css file and a background JPEG file.
