A Boolean that indicates whether the scroll view draws its background.
- macOS 10.0+
When the value of this property is
YES, the scroll view cell fills the background with its background color.
If the scroll view encloses an
NSClip, setting this property to
NO also sets the
NO. The side effect of setting
draws directly on the
NSClip instead is the appearance of “trails” (vestiges of previous drawing) in the document view as it is scrolled.
