There's no supported way to do it and never has been; back in the day when Java's compatibility test had a "set button color", the MacLookAndFeel got an exemption because it's just not possible.
If you look in the Calendar app bundle it has grayscale checkbox images, which they probably colorize with code specific to Calendar - so even Apple is "using images to mimic the UI" - and since it's specific to the OS it ships with, it doesn't have to worry about mismatches if it runs on a different one. ----- Original Message ----- From: "Alex Kac" <a...@webis.net> To: "SevenBits" <sevenbitst...@gmail.com> Cc: "Cocoa-Dev" <Cocoa-dev@lists.apple.com> Sent: Thursday, June 5, 2014 10:42:48 PM Subject: Re: Simple question? NSButton/checkbox color OK maybe I’m not being clear. We need to have a checkbox that can be colored, exactly the same way that the Calendar app on both color their checkboxes for the calendar they are representing. Right now the only way I can think of doing that is to create a checkbox image, and color it, and use that. Obviously if we do that, we have to have different images for Mavericks and Yosemite. So we have to mimic Yosemite. I’d prefer NOT to have to create mimicked checkbox images. That’s what I’m trying to prevent. I’m asking all the AppKit gurus here if there is a better way, a more proper way, to color a checkbox control without having to use images to mimic the UI of the OS we’re running on.
