Flex Examples
The following example shows how you can apply styles to individual thumbs in a MX HSlider control in Flex by calling the getThumbAt() method to get a specific thumb and then calling the setStyle() method to apply the styles.
Full code after the jump.

The following example shows how you can do the same thing in Flex 4 by setting the chromeColor style instead of the themeColor and fillColors styles.
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.

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.
