I didn't pull my code from Chromium, I just noticed in my googling that they used the undocumented method that is required to get the mouse over effects to work.
I ended up sticking with the standard Cocoa buttons that NSWindow provides for my custom window as it requires the least amount of code to use. The main things I had to do are: - Redraw the buttons when the window's key/main state changes - Track the mouse to redraw the buttons when the mouse enters/exits the group of buttons - Override in the button's superview _mouseInGroup: to return YES when the mouse is over any of the buttons - After the window is minimized, make sure the buttons redraw again with the mouse not being over the buttons I can post a sample project if someone wants, but I think that should cover it for anyone wanting to do this themselves.
