Bug 215943 – WKUIDelegate's contextMenuConfigurationForElement API method isn't called for images

• Status: NEW
• Component: WebKit API

[Ali Juma]

The public API method -[WKUIDelegate webView:contextMenuConfigurationForElement:completionHandler] is only called for links, not for images. The SPI version (-[WKUIDelegate _webView:contextMenuConfigurationForElement:completionHandler]) does get called for images.

This means that WKWebView embedders cannot easily customize the context menu shown for images.

The logic for this is in -[WKContentViewInteraction continueContextMenuInteraction:], which does:
 if (_positionInformation.isLink && [uiDelegate respondsToSelector:@selector(webView:contextMenuConfigurationForElement:completionHandler:)]) {
     .....
 } else if ([uiDelegate respondsToSelector:@selector(_webView:contextMenuConfigurationForElement:completionHandler:)]) {
     .....
 }

Could we change the first condition to also include |_positionInformation.isImage|?

This API was designed to be a replacement for the API it deprecated without substantial changes.  We are considering improving the context menu API, and this input is noted.
