(Incomplete) list of WebEngine features, and how to test for them. Actively maintained list is available on a dedicated documentation page: Qt WebEngine Features

Chromium DevTools

Version: Qt 5.4.0 onwards

Description: Ability to inspect and debug layout and performance issues of any web content.

Documentation: Qt WebEngine Developer Tools and Debugging with WebEngine

How to test: Launch a QtWebEngine app with command line option --remote-debugging-port=[your-port] and use any QtWebEngine-based example browser (from the same version) instance to connect to http://localhost:[your-port]. See documentation for details. Also, widgets' based simplebrowser[1] and quicknanobrowser[2] examples implement opening devtools in a separate view through context menu.

WebRTC

Version: Qt 5.4.0 onwards

Description: Real-Time Communications (RTC) capabilities via simple APIs

Documentation: WebRTC usage

How to test: Set up a webcam / microphone. Open e.g. https://test.webrtc.org/ in simplebrowser[1] for simple test of supported capabilities. Also https://www.webrtc-experiment.com/RecordRTC/ is good to just test screen recording.

HTML5 Geolocation

Version: Qt 5.5.0 onwards

Description: Javascript Geolocation API with QtLocation as a backend

Documentation: HTML5 Geolocation

How to test: QtLocation should be built before QtWebEngine. Using simplebrowser[1], go to http://html5demos.com/geo, and allow the page to find your position. Note that on Windows you need an external GPS receiver connected, see QtPositioning documentation.

PPAPI / Adobe Flash

Version: Qt 5.6.0 onwards

Description: Support for PPAPI plugins, and Flash in particular

Documentation: Pepper Flash Player Plugin Support and Pepper Flash Player Plugin Support

How to test: Make sure you have the Adobe Flash PPAPI plugin installed. Launch DemoBrowser, NanoBrowser, and make sure that 'Plugins' are enabled. Load https://helpx.adobe.com/flash-player.html .

Fullscreen

Version: Qt 5.6.0 onwards

Description: Support for viewing content in fullscreen mode.

Documentation: Fullscreen API support

How to test: Use either specialized videoplayer[3] example or just quicknanobrowser[2] and go to youtube.com or vimeo.com and pick any video. Click on the full screen icon to go into fullscreen mode.

Drag & Drop

Version: Qt 5.7.0 onwards

Description: Support for HTML5 drag and drop.

Documentation: Drag and Drop support

How to test: Try any HTML5 drag and drop demo. E.g. this, that or maybe even yon, or w3schools one. Dragging files into the browser is not part of HTML5 but also works. Try also to invoke context menu of simplebrowser[1] or quicknanobrowser[2] and click 'Save page', which will land an offline copy of a page into default downloads directory. Then just drag this file back to browser from a system file explorer. That should open an offline page through file url.

Printing to PDF

Version: Qt 5.7.0 onwards

Description: Support for printing a web page to a PDF file.

Documentation: Print to PDF file

How to test: Use html2pdf[4] and printme[5] examples to test the feature.

HTML5 DRM video

DRM Protected, widevine plugin

Version: Qt 5.7.0 onwards

Description: Support for viewing DRM protected videos.

How to test: QtWebEngine should be built with proprietary codecs enabled (pass '-proprietary-codecs' to configure when building qt). Try and view videos at. e.g. http://demo.castlabs.com/, http://ssdemo04.swankmp.net/ or https://shaka-player-demo.appspot.com/demo/.

Local Storage

Description: Support for HTML5 local storage.

How to test: It seems currently there are only auto-tests in qtwebengine/tests/auto/widgets/qwebenginepage, and no manual tests or examples.

WebGL

Description: Support for HTML 5 WebGL

How to test: Visit http://webglsamples.org/ or https://threejs.org/examples/ and try available demos.

WebSockets

Description: Support for HTML 5 WebSockets

How to test: Try simple online test echo server https://www.websocket.org/echo.html
