# knobStyle

The scroller’s knob style.

## Declaration

```swift
var knobStyle: NSScroller.KnobStyle { get set }
```

## Discussion

Discussion The value of this property does not affect legacy scrollers. NSScroller.KnobStyle.default is appropriate for a wide range of content, but in some cases choosing an alternative knob style may enhance visibility of the scroller knob atop some kinds of content. For a list of possible values, see NSScroller.KnobStyle.
