Flex BorderContainer with dashed lines border

I want to write a skin for BorderContainer wi开发者_Python百科th dashed line stroke. I haven't found a property in SolidColorStroke or *Stroke class that provides this feature. Is there a Stroke class that provides dashed lines drawing?

Not included with default fxg primitives but there are some third party libraries such as http://www.tink.ws/blog/primitives/
