Styling specific states in a Spark ToggleButton control in Flex 4 (redux)

In a previous example, “Styling specific states in a Spark ToggleButton control in Flex 4”, we saw how to style specific states in a Flex 4 Spark ToggleButton control using CSS by specifying the state name after the control name in the <Script> block.

The following example shows how you can set styles on specific states on a Flex 4 Spark ToggleButton control using ActionScript.

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 To download the latest nightly build of the Flex 4 SDK, see

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.
