JMenuBar showing gradient background on Mac -- how to disable?
posted 6 years ago
JMenuBar on Mac OS adds a gradient, which I don't want. See the simple example below. (Note, the gradient is very subtle. Using Mac OS's DigitalColorMeter utility, you can detect it.) Does anyone know how I can get rid of it. No matter what I set the background color to, it adds this subtle gradient on top of it. UIManager.get("MenuBar.gradient") returns null. Any ideas?
(Busted. Sorry, I'll be sure to say when I'm posting to more than one forum in the future.) I think the below example makes the issue a little clearer. If you add the JMenuBar to a JPanel, instead of using setJMenuBar on the JFrame, you can see the gradient clearer. Notice the top of the JMenuBar is lighter than the bottom. Is there a way to disable that? Thanks.
