The depth limit of the window.
- macOS 10.0+
The value of this property can be examined with the Application Kit functions
bits. In addition, the
NSBest function provides the best depth limit based on a set of parameters.
Setting this property to
0 sets the depth limit to the window’s default depth limit. A depth limit of
0 can be useful for reverting a window object to its initial depth. You can also use one of the explicit bit depths defined in Explicit Window Depth Limits (
NSWindow is the default).
