Recently Qt introduced the QtWebEngine module. Is there a way to invoke developer tools and debug JavaScript code inside QWebEngineView? It was possible with QWebView using 

page()->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);

but I couldn't find any similar option in QWebEngineView.

I just ran across this so I added it here for posterity.

It was just added to Qt 5.5 git. You have to enable it via an environment variable QTWEBENGINE_REMOTE_DEBUGGING=<port>. You can put 0.0.0.0:<port> if you are doing debugging of an embedded device and cant use the local console. Then you can point can connect to http://127.0.0.1: to get the debugger. It will need to be a chromium based browser. Do you have to use Chrome, or you can actually use the "quick nano browser" example if you want.
