## Discussion

If your app implements its own scrolling, or one of your responder objects tracks scroll wheel messages before they reach a scroll view, make sure the value of this property is <doc://com.apple.documentation/documentation/Swift/true> before you call [`trackSwipeEvent(options:dampenAmountThresholdMin:max:usingHandler:)`](/documentation/AppKit/NSEvent/trackSwipeEvent(options:dampenAmountThresholdMin:max:usingHandler:)) to handle the event. The system defines the value of this property based on user-level preferences.

If you use [`NSScrollView`](/documentation/AppKit/NSScrollView) for your app’s scrolling behavior, you don’t need to check this property. Scroll views automatically account for this behavior.
