The following example shows how you can change the value in a Flex 4 HSlider control by using the changeValueByStep() method.
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 beta, check out the Adobe Flash Builder 4 page on the Adobe Labs site. To download the latest build of the Flex 4 SDK, see http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4. For instructions on using the beta Flex 4 SDK in Flex Builder 3, see "Using the beta Flex 4 SDK in Flex Builder 3".

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.

I hate to be “that guy”, but I have a Flex example I’d like to share with you so you can post it. I cannot for the life of me figure out how to contact you, could you email me (and then nuke this comment). Thanks Peter.
