# drawsBackground

A Boolean that indicates whether the scroll view draws its background.

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

## Discussion

When the value of this property is <doc://com.apple.documentation/documentation/Swift/true>, the scroll view cell fills the background with its background color.

If the scroll view encloses an `NSClipView`, setting this property to <doc://com.apple.documentation/documentation/Swift/false> also sets the `NSClipView` property [`copiesOnScroll`](/documentation/AppKit/NSClipView/copiesOnScroll) to <doc://com.apple.documentation/documentation/Swift/false>. The side effect of setting `drawsBackground` directly on the `NSClipView` instead is the appearance of “trails” (vestiges of previous drawing) in the document view as it is scrolled.
