# windowTitle(forDocumentDisplayName:)

Returns the window title to be used for a given document display name.

## Declaration

```swift
func windowTitle(forDocumentDisplayName displayName: String) -> String
```

## Parameters

- `displayName`: The display name for the document. This is the last path component under which the document file is saved.

## Discussion

Discussion The default implementation returns displayName. Subclasses can override this method to customize the window title. For example, a CAD application could append “-Top” or “-Side,” depending on the view displayed by the window.
