It accepts a `WheelEvent` object as a parameter, representing the scroll event. The method's primary action is to scroll the flyout based on the wheel event data. It does not return any value, indicated by the `void` return type. The method is protected, meaning it can be called by subclasses of `HorizontalFlyout`.\n"]]
