# cornerView

The view used to draw the area to the right of the column headers and above the vertical scroller of the enclosing scroll view.

## Declaration

```swift
var cornerView: NSView? { get set }
```

## Return Value

Return Value The view used to draw the area to the right of the column headers and above the vertical scroller of the enclosing NSScrollView object.

## Discussion

Discussion The default corner view draws a bezeled rectangle using a blank NSTableHeaderCell object, but you can replace it with a custom view that displays an image, or with a control that can handle mouse events, such as a Select All button. Your custom corner view should be as wide as a vertical NSScroller object and as tall as the header view of the table view.
