# autoscroll(with:) Scrolls the view’s closest ancestor [`NSClipView`](/documentation/AppKit/NSClipView) object proportionally to the distance of an event that occurs outside of it. ``` func autoscroll(with event: NSEvent) -> Bool ``` ## Parameters `event` An event object whose location should be expressed in the window’s base coordinate system (which it normally is), not the receiving view’s. ## Return Value Returns if any scrolling is performed; otherwise returns . ## Discussion View objects that track mouse-dragged events can use this method to scroll automatically when the cursor is dragged outside of the [`NSClipView`](/documentation/AppKit/NSClipView) object. Repeated invocations of this method (with an appropriate delay) result in continual scrolling, even when the mouse doesn’t move. ## See Also [`func isDescendant(of: NSView) -> Bool`](/documentation/AppKit/NSView/isDescendant(of:)) Returns a Boolean value that indicates whether the view is a subview of the specified view. [`func autoscroll(with: NSEvent) -> Bool`](/documentation/AppKit/NSClipView/autoscroll(with:)) Scrolls the clip view proportionally to `theEvent`’s distance outside of it. --- Copyright © 2026 Apple Inc.
