# update(with:)

Informs the feedback filter about a new event.

```
func update(with event: NSEvent)
```

## Parameters

`event`

An event ([`NSEvent`](/documentation/AppKit/NSEvent)) to be filtered, which matches an event type returned by the [`inputEventMask`](/documentation/AppKit/NSAlignmentFeedbackFilter/inputEventMask) method.

## Discussion

This method informs the feedback filter about a new event to be filtered, which matches an event type returned by the [`inputEventMask`](/documentation/AppKit/NSAlignmentFeedbackFilter/inputEventMask) method. Call the `updateWithEvent:` method instead of [`update(withPanRecognizer:)`](/documentation/AppKit/NSAlignmentFeedbackFilter/update(withPanRecognizer:)) if you are using a tracking loop controller for event tracking.
