# rect(for:)

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

## Declaration

```swift
func rect(for partCode: NSScroller.Part) -> NSRect
```

## Discussion

Discussion See NSScroller.Part for a list of possible values for aPart. Note the interpretations of NSScrollerDecrementPage and NSScrollerIncrementPage. The actual part of an NSScroller that causes page-by-page scrolling varies, so as a convenience these part codes refer to useful parts different from the scroll buttons. Returns NSZeroRect if the part requested isn’t present on the receiver.
