问题 I've got the latest Beta of Adobe Flash Builder 4. I want to use a <s:List> component, and specify the dataProvider as being an XML file.

This would be fairly straightforward if the column I want colored was part of the dataProvider. Instead, I am calculating it based on two other columns that are part of the dataProvider.

问题 There is any way to make a text "textured" - with a result similar to this: http://www.entheosweb.com/fireworks/patterned_text.asp In Flex (so using AS3)?
