# displayIfNeededIgnoringOpacity(_:)

Acts as [`displayIfNeeded()`](/documentation/AppKit/NSView/displayIfNeeded()), but confining drawing to `aRect` and not backing up to the first opaque ancestor—it simply causes the view and its descendants to execute their drawing code.

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

## Parameters

`rect`

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