# NSWindowTab

A tab associated with a window that is part of a tabbing group.

```
class NSWindowTab
```

## Overview

[`NSWindowTab`](/documentation/AppKit/NSWindowTab) describes the way a window displays as part of a tabbed window group. The properties of [`NSWindowTab`](/documentation/AppKit/NSWindowTab) are configurable at any time, but only take effect when the associated [`NSWindow`](/documentation/AppKit/NSWindow) displays in a tab.

AppKit automatically creates an instance of [`NSWindowTab`](/documentation/AppKit/NSWindowTab) for each [`NSWindow`](/documentation/AppKit/NSWindow). You can access a window’s tab object using the [`tab`](/documentation/AppKit/NSWindow/tab) property.
