[`+ (CGFloat) scrollerWidthForControlSize:(NSControlSize) controlSize;`](/documentation/AppKit/NSScroller/scrollerWidthForControlSize:)

Returns the width of the scroller based on `controlSize` and assuming a scroller style of [`NSScroller.Style.legacy`](/documentation/AppKit/NSScroller/Style/legacy).

[`- (void) setFloatValue:(float) value knobProportion:(CGFloat) proportion;`](/documentation/AppKit/NSScroller/setFloatValue:knobProportion:)

Sets the position of the knob to `aFloat`, which is a value from 0.0 (indicating the top or left end) to 1.0 (the bottom or right end).

[`func drawArrow(NSScroller.Arrow, highlight: Bool)`](/documentation/AppKit/NSScroller/drawArrow(_:highlight:))

Draws the scroll button indicated by `arrow`, which is either `NSScrollerIncrementArrow` (the down or right scroll button) or `NSScrollerDecrementArrow` (up or left).

### Deprecated properties

[`var arrowsPosition: NSScroller.ArrowPosition`](/documentation/AppKit/NSScroller/arrowsPosition)

The location of the scroll buttons within the scroller, as described in [`NSScroller.ArrowPosition`](/documentation/AppKit/NSScroller/ArrowPosition).

[`var controlTint: NSControlTint`](/documentation/AppKit/NSScroller/controlTint)

The scroller’s control tint.

### Deprecated enumerations

[`enum Arrow`](/documentation/AppKit/NSScroller/Arrow)

These constants describe the two scroller buttons and are used by [`drawArrow(_:highlight:)`](/documentation/AppKit/NSScroller/drawArrow(_:highlight:)).

[`enum ArrowPosition`](/documentation/AppKit/NSScroller/ArrowPosition)
