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.

    1. @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:

      <s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"
          xmlns:fb="http://ns.adobe.com/flashbuilder/2009" alpha.disabled="0.5" blendMode="normal">
