Why can't I import mx.controls into a Flex ActionScript project

Question

I'm trying to do a simple import into an ActionScript Project that I've created in Flex Builder:

import mx.controls.Label;

It won't let me. Code hinting shows no 'controls' after mx.

Any idea what's going on?

Thanks.

To access mx libraries in an Actionscript Project, you need to point Flex Builder to the source path.

Right click on your Project -> Properties -> Actionscript Build Path -> Source path tab -> Add Folder... -> 'C:\\Program Files\\Adobe\\Flex Builder 3\\sdks\\SDK_VERSION_NUMBER_HERE\\frameworks\\source\\'

and now you can access all the mx.* classes.
