Flex Examples

The following example shows how you can embed a font in the Flex Gumbo beta and use the embedded font with the new TextView class using the latest version (build 4.0.0.3616) of the beta Flex Gumbo SDK.

Full code after the jump.

To use the following code, you must have Flash Player 10 and a Flex Gumbo SDK installed in your Flex Builder 3. For more information on downloading and installing the Gumbo SDK into Flex Builder 3, see “Using the beta Gumbo SDK in Flex Builder 3″.

This entry is based on a beta version of the Flex Gumbo 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 Gumbo SDK.

For examples of embedding fonts in earlier versions of Flex (Flex 3 and earlier), see the Font tag archive at http://blog.flexexamples.com/category/fonts/.
