Remove the scroll in WebKit View

WkWebView is very opaque. It is almost always a better idea to do such things in CSS or Javascript inside the view.

Things are easy in iOS? Are you in MacOS app ?

In that case, you may have to subclass and implement scrollWheel:

func scrollWheel(with event: NSEvent)

in iOS:

There is a scrollView associated to the webView:

webView.scrollView

Not sure it works in MacOS (except Catalyst)

See discussion here on WebView in MacOS

https://stackoverflow.com/questions/34363924/webview-vs-wkwebview-on-osx

Did you try to set its

isScrollEnabled property to false ?

Or use those properties (iOS):

var showsHorizontalScrollIndicator: Bool

A Boolean value that controls whether the horizontal scroll indicator is visible.

var showsVerticalScrollIndicator: Bool

A Boolean value that controls whether the vertical scroll indicator is visible.

In MacOS, there are

var hasHorizontalScroller: Bool

A Boolean that indicates whether the scroll view has a horizontal scroller.

var hasVerticalScroller: Bool

A Boolean that indicates whether the scroll view has a vertical scroller.

Thank you Claude. I know how to do that in iOS. I am asking only for macOS.

I do not know how to apply your suggestions. For instance,

var hasVerticalScroller: Bool

In MacOS, I tested this:

Subclass and implement scrollWheel:

func scrollWheel(with event: NSEvent)

See here

Code is

import Cocoa
import WebKit

class MyWKWebView: WKWebView {
    override func scrollWheel(with event: NSEvent) {
         print("NoScroll")     // Just to see scroll did not occur
    }
}

class WebViewController: NSViewController, WKUIDelegate {
   
    var webView: MyWKWebView! 
   
    override func loadView() {
        super.loadView()

        let webConfiguration = WKWebViewConfiguration()
        webView = MyWKWebView(frame: CGRect(x: 0, y: 0, width: 300, height: 300), configuration: webConfiguration)
        webView.uiDelegate = self

        view = webView
    }
   
    override func viewDidLoad() {
        super.viewDidLoad()
       
        var myURL: URL!
        myURL = URL(string: "https://developer.apple.com/")
        let myRequest = URLRequest(url: myURL!)
        webView.load(myRequest)
        webView.allowsMagnification = true
        webView.magnification = 0.25
        webView.setMagnification(0.25, centeredAt: CGPoint(x: 150, y: 150))

    }
   
}

In addition, you should check the system Preferences > General.

Check that

Display sidebars

is not set to always.
