# tabbingMode

A value that indicates when a window displays tabs.

## Declaration

```swift
var tabbingMode: NSWindow.TabbingMode { get set }
```

## Discussion

Discussion Set this to the desired tabbing mode before displaying a window. The default value is NSWindow.TabbingMode.automatic. When the value is NSWindow.TabbingMode.automatic, the system uses userTabbingPreference to determine tabbing behavior. For a list of possible values, see NSWindow.TabbingMode.
