# update(withPanRecognizer:)

Informs the feedback filter about a new pan (drag) gesture recognizer event.

```
func update(withPanRecognizer panRecognizer: NSPanGestureRecognizer)
```

## Parameters

`panRecognizer`

The gesture recognizer ([`NSPanGestureRecognizer`](/documentation/AppKit/NSPanGestureRecognizer)) that produced the event.

## Discussion

This method informs the feedback filter about a new pan (drag) gesture recognizer event. Call this method instead of [`update(with:)`](/documentation/AppKit/NSAlignmentFeedbackFilter/update(with:)) if your event tracking uses gesture recognizers.

## See Also

[`NSGestureRecognizer`](/documentation/AppKit/NSGestureRecognizer)

An object that monitors events and calls its action method when a predefined sequence of events occur.

[`NSPanGestureRecognizer`](/documentation/AppKit/NSPanGestureRecognizer)

A continuous gesture recognizer for panning gestures.
