# canPropagateSelectedChildViewControllerTitle

A Boolean value indicating whether the tab view controller gets its title from the selected child view controller.

```
var canPropagateSelectedChildViewControllerTitle: Bool { get set }
```

## Discussion

When this property is <doc://com.apple.documentation/documentation/Swift/true> and the tab view controller’s own title is `nil`, the tab view controller gets its title from the [`title`](/documentation/AppKit/NSViewController/title) property of the selected child view controller. When this property is <doc://com.apple.documentation/documentation/Swift/false>, the tab view controller always provides the title, which may be `nil`. The default value of this property is <doc://com.apple.documentation/documentation/Swift/true>.
