# drawKnob()

Draws the knob.

```
func drawKnob()
```

## Discussion

You should never need to invoke this method directly, but may wish to override it to customize the appearance of the knob.

[`func rect(for: NSScroller.Part) -> NSRect`](/documentation/AppKit/NSScroller/rect(for:))

Returns the rectangle occupied by `aPart`, which for this method is interpreted literally rather than as an indicator of scrolling direction.
