the link, image or other element on which the contextual menu is totally unknown.

Another thing we can find out is that the menu and its items do not contain any information about the context, e.g.

If an Image was clicked we find „ WKMenuItemIdentifierOpenImageInNewWindow“ and „ WKMenuItemIdentifierDownloadImage“ and for videos „ WKMenuItemIdentifierOpenMediaInNewWindow“ and „ WKMenuItemIdentifierDownloadMedia“

The second thing we can find out is that if a link is clicked, we find menu items with the ID „ WKMenuItemIdentifierOpenLinkInNewWindow“ and „ WKMenuItemIdentifierDownloadLinkedFile“.

The first thing we can find out is that the „ identifier“ property of the menu items is very clear about the meaning, and these identifiers look very stable – they haven’t changed between different macOS releases.

So some simple reverse engineering is required to find out the meaning of the default menu items and their actions.

This sounds easy, but there are a few issues.īecause Apple does not officially provide a way to customize the contextual menu, nothing is officially documented. In „ willOpenMenu“ the parameter „menu“ represents the contextual menu, so we can easily inspect all the available menu items, remove what we don’t need and add all the new menu items we want to have in the menu. In the „ willOpenMenu“ method we can add, modify or remove menu items and in „ didCloseMenu“ we would reset anything that needs to be reverted back to normal. So in order to customize the contextual menu of WKWebView, we could simply subclass WKWebView and override these methods in order to modify this menu.

Which is called after the contextual menu has closed. Open func didCloseMenu( _ menu: NSMenu, with event: NSEvent) Which is called before the contextual menu of the view will open and Open func willOpenMenu( _ menu: NSMenu, with event: NSEvent)

WKWebView is a subclass of an NSView on the Mac and the NSView class has methods to deal with a contextual menu.

It’s not that obvious how to do this, but it can be done.īecause the WKWebView API for macOS itself does not provide anything at all which deals with the contextual menu, we need to look elsewhere. This article explains how you can customize the contextual menu of WKWebView under macOS as well. Unfortunately under macOS the WKWebView does not provide such a method for its contextual menu. Under iOS the WKWebView class provides a delegate method which allow to customize the contextual menu of the web engine (the menu which opens when long-pressing a link).
