Detailed Description

WebEngineView control offers a HTML browser engine based on Chromium/QtWebEngine.

To facilitate debugging of the control, you can enable the logConsoleOutput MDL tag. Another option is to set the environment variable QTWEBENGINE_REMOTE_DEBUGGING to a port number (e.g. 4567) and then connect a Google Chrome browser to http://127.0.0.1:4567/ to use the remote debugging tools.
