Get “fat header” background color in Swing

Question

I'm building a Swing app in which I'd like to put a "fat header" as in this image:

Is there a nice way to get the native system colour for that background area? So on Ubuntu with a default theme I'd like to get the colour in the image, but for other themes, and on Windows, I'd also like to have something sensible. I'm using the native Look & Feel.

例如 ，FatHeader可能是JMenuBar或带有GradientPaint JPanel （非常简单，是从JButton's JComponents获取此Gradient[] ）
