How Qt WebEngine can help support modern web technologies for your app
summary
Compares WebKit vs Qt WebEngine and shows that WebEngine uses a multi‑process model with asynchronous callback APIs, so there is no direct C++ DOM access and JavaScript injection becomes the way to modify pages. Demonstrates using injected jQuery for auto‑login then replacing hard‑coded creds with a Qt WebChannel C++/JS bridge that reads properties live. Covers profile/incognito usage, request interceptors, enabling Chrome DevTools via a remote debug port, and platform limits like no mobile support and Mac App Store incompatibility.
