# getPeriodicDelay(_:interval:) Returns the initial delay and repeat values for continuous sending of action messages to target objects. ``` func getPeriodicDelay(_ delay: UnsafeMutablePointer, interval: UnsafeMutablePointer) ``` ## Parameters `delay` On input, a pointer to a floating-point variable. On output, the variable contains the current delay (measured in seconds) before messages are sent. This parameter must not be `NULL`. `interval` On input, a pointer to a floating point variable. On output, the variable contains the interval (measured in seconds) at which messages are sent. This parameter must not be `NULL`. ## Discussion The default implementation returns a delay of `0.2` and an interval of `0.025` seconds. Subclasses can override this method to supply their own delay and interval values. ## See Also [`var isContinuous: Bool`](/documentation/AppKit/NSCell/isContinuous) A Boolean value indicating whether the cell sends its action message continuously during mouse tracking. --- Copyright © 2026 Apple Inc.
