Text tabbed interface new to Lion

I like the new tab interface displayed in the Lion “About This Mac” window. It's not gorgeous, but I think it's extremely 开发者_运维百科useful in presenting information where icons would most probably fail to do a good job.

Question is: is that UI available from standard Cocoa components? I.e., can something similar to it be built with Xcode, without resorting to custom classes with custom drawing code?

Isn't that just a toolbar without images?
