Flex Examples
The following example shows how you can style the disabled state on a Spark TextInput control in Flex 4.
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 http://www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see http://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.

View source is enabled 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.

Nice example but is it also possible to style the alpha of the disabled state? I tried using content-background-alpha but that doesn’t seem to do the trick…
@Tom Van den Eynde,
I believe you can change the disabled alpha by creating a custom skin. For example, here is top bit of the default spark.skins.spark.TextInputSkin.mxml file:
