# horizontalRulerView

The scroll view’s horizontal ruler view.

## Declaration

```swift
var horizontalRulerView: NSRulerView? { get set }
```

## Discussion

Discussion The value of this property is nil when the scroll view has no horizontal ruler view. If the scroll view is set to display a horizontal ruler view and doesn’t yet have one, this property creates an instance of the ruler view class set using the class method setRulerViewClass(_:). You can use this property to override the default ruler class set using the class method setRulerViewClass(_:). Display of rulers is controlled using the rulersVisible property.
