亮点：

Using Flash Components in Flex

You can insert Flash components into Flex by importing from fl.controls.* package.

You will need the following FlashControls.swc file, in order for the compiler to recognize the package path. Download the file. In your project properties, go to "ActionScript BuildPath", select the tab "Library Path", and click on "Add SWC..." to add FlashControls.swc to your build path.
