# windowNibName

The name of the nib file that stores the window associated with the receiver.

## Declaration

```swift
var windowNibName: NSNib.Name? { get }
```

## Discussion

Discussion If init(windowNibPath:owner:) was used to initialize the instance, windowNibName contains the last path component with the “.nib” extension stripped off. If init(windowNibName:) or init(windowNibName:owner:) was used, NSWindowController contains the name without the “.nib” extension.
