Is there a way to hide the titlebar in an NSWindow? I don\'t want to have to completely write a new custom window. I can\'t use NSBorderlessWindowMask because I have a botto
The only way I know would be to create a window without a titlebar (see NSBorderlessWindowMask). Note that you can't (easily) create a window without a titlebar in IB, so you will have to do a bit of work in code (there are a couple of different approaches, you can probably figure it out).
A big drawback with using a window without a titlebar is that you're now on the hook for much more of the standard appearance and behaviour - rounded corners and such.
