# setPeriodicDelay(_:interval:)

Sets the message delay and interval periods for a continuous button.

```
func setPeriodicDelay(_ delay: Float, interval: Float)
```

## Parameters

`delay`

The amount of time (in seconds) that a continuous button will pause before starting to periodically send action messages to the target object. The maximum allowed value is 60.0 seconds; if a larger value is supplied, it is ignored, and 60.0 seconds is used.

`interval`

The amount of time (in seconds) the continuous button will pause between sending each action message. The maximum value is 60.0 seconds; if a larger value is supplied, it is ignored, and 60.0 seconds is used.

## Discussion

The delay and interval values are used if the button is configured (by a [`isContinuous`](/documentation/AppKit/NSControl/isContinuous) message) to continuously send the action message to the target object while tracking the mouse.

## See Also

[`var isContinuous: Bool`](/documentation/AppKit/NSControl/isContinuous)

A Boolean value indicating whether the receiver’s cell sends its action message continuously to its target during mouse tracking.
