Using a CFF embedded font with a Halo List control in Flex 4

The following example shows how you can use a CFF/DefineFont4 embedded font with a Halo/MX List control in Flex 4 by setting the textFieldClass style to the new mx.core.UIFTETextField class.

Full code after the jump.

The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.

For more information on getting started with Flex 4 and Flash Builder 4, see the official Adobe Flex Team blog.

Or you can set the textFieldClass style on the mx|ListItemRenderer selector, as seen in the following example:

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.
