How to detect the change in HSlider when value is updated

Is there a way to detect the value change in HSlider开发者_高级运维 (in Flex 4.0) without touching the slider.

Basically, what I wanted is to detect if the slider value was changed programmatically. Ex.

slider.value += 3; // where slider is a slider component

Thanks.

FlexEvent.VALUE_COMMIT event is dispatched. Just listen to it.
