QtWebEngine – Taming the beast
summary
QtWebEngine embeds Chromium (multi‑process, separate renderer) into Qt since 5.4 and updates in 5.5/5.6 add deeper APIs: QWidget and Qt Quick views, call QWebEngine::initialize to share GL context, remote debugging via Chrome DevTools, console forwarding, runJavaScript with callbacks, and WebEngineScript collection with injection points and isolated worlds. Use QWebChannel for async C++↔JavaScript messaging, support for WebRTC and geolocation, request interceptors/custom schemes/cookie control, Pepper plugins (Flash), and OpenGL is required for best performance.
