# displayIgnoringOpacity(_:)

Displays the view but confines drawing to a specified region and does not back up to the first opaque ancestor—it simply causes the view and its descendants to execute their drawing code.

```
func displayIgnoringOpacity(_ rect: NSRect)
```

## Parameters

`rect`

A rectangle defining the region of the view to be redrawn; it should be specified in the coordinate system of the view.
