Type Property

borderless

The window displays none of the usual peripheral elements. Useful only for display or caching purposes. A window that uses NSWindowStyleMaskBorderless can’t become key or main, unless the value of canBecomeKey or canBecomeMain is true. Note that you can set a window’s or panel’s style mask to NSWindowStyleMaskBorderless in Interface Builder by deselecting Title Bar in the Appearance section of the Attributes inspector.
