Print JS console messages by default
Change the behavior of QWebEnginePage/WebEngineView to print JavaScript console.warn and console.error messages by default in a 'js' logging category. This matches also the behavior for QtQml, where console messages end up in a 'qml' logging category by default. So far access to the JavaScript console required either use of the remote debugging functionality, subclassing of QWebEnginePage, or implementing a custom handler. Anyhow, even then writing a seamless forwarding of the data and metadata to the Qt message handler is difficult. This patches implements this forwarding by default. The behavior can be changed by either setting up rules for the 'js' category, e.g. setFilterRules("js.*=false"); or by implementing onJavaScriptConsoleMessage(), or overriding QWebEnginePage::javaScriptConsoleMessage. [ChangeLog] Unhandled JS console messages are now forwarded to to the Qt message handler inside a 'js' category. Change-Id: I5480383a80dcf7a122496f9b7915264ef9036db3 Reviewed-by: Joerg Bornemann <>
