Cocoa - Replicate mail button bar

Question

How do I replicate the appearance of the button bar in the Mail App? I'm pretty close, but I cannot seem to get the colors to work the way I want.

If I set the background color for the view containing the buttons, it won't look the same as the NSTableView above it when the window loses focus.

Here is my app with focus:

My app without focus:

Mail.app with focus:

Mail.app without focus:

So in short, I want the same behaviour as the mail button bar with or without focus. How would one do that?

Answer 1

After spending a lot of time on this and then after finally asks a question here, I manage to fix it.

What I did was adding a bottom bar in IB and then programmatically setting the same color on the bottom bar as the background color on the NSTableView.
