# didExitFullScreenNotification

A notification that the window object exited full-screen mode.

```
class let didExitFullScreenNotification: NSNotification.Name
```

## Discussion

The system posts this notification when a window moves in front of other windows or when other windows move from in front of it, exposing part of its content.

The notification object is the [`NSWindow`](/documentation/AppKit/NSWindow) object that exposes its content. In the notification’s `userInfo` dictionary, the key `NSExposedRect` specifies an <doc://com.apple.documentation/documentation/Foundation/NSValue> object that contains the rectangle the window exposed.

To observe this notification using Swift concurrency, use [`NSWindow.DidExitFullScreenMessage`](/documentation/AppKit/NSWindow/DidExitFullScreenMessage).
