The cell’s background style.
- macOS 10.5+
The background describes the surface the cell is drawn onto in the
draw method. A control typically sets the value of this property before it asks the cell to draw. A cell may draw differently based on background characteristics. For example, a table view drawing a cell in a selected row might set the value to
NSBackground. A text cell might decide to render its text white as a result. A rating-style level indicator might draw its stars white instead of gray.
