Is Websocket support planned?

[naiteon]

I have a local html file in a raspberry pi that i open thru chromium in kiosk mode. It works really well connects to both local and remote websocket servers. But I'm afraid it is gonna mess up in the future since there is no way to stop chromium from trying to auto update and who knows which undesired UI prompt or window they may come up with next release, which i can't show to the kiosk users!

I tried this module then in the hopes i could have a webview without future messes from chromium BUT unfortunately it can't connect to any websocket server. I tried to read through the issues to see if websocket is supported but it is still inconclusive.

Is there any flag or parameter required to enable websocket?

As you have probably seen already there are a couple of old issues related to web sockets, all of them are resolved in one way or another. I have not personally tested web sockets on RPI or elsewhere, so I have no idea how well it is supported. GTK is currently the only viable renderer choice for RPI and the truth is it is not very capable.

I think the best course would be to get QT with QTWebEngine support up and running on RPI. I have investigated it to some extent as described here https://github.com/r0x0r/pywebview/issues/523, but could not get it running. More specifically QT works fine, but not QTWebEngine. Help is appreciated.

Thank you so much for your attention and kind response @r0x0r ! I ended up using GTK and WebKit2 in C++. I think we could make a webkit2 binding through gtk. I could help if you want.

Pywebview uses GTK and WebKit2 already. Is C++ variant any different?

Oh that's weird! yeah i tried pywebview and the html/js loaded successfully but the websocket connection wouldn't work. When I tried the equivalent example with C++ it worked, both the html js and websocket worked. I don't know exactly why, but I can guarantee you the files were the same! In c++ i used the webview_web_view_load_uri (and also webview_web_view_load_html) both worked out of the box.

On the raspberry pi I've used these libraries:

libgtk-3-dev libwebkit2gtk-4.0-37 libwebkit2gtk-4.0-dev

[r0x0r]

pywebview uses PyGObject with relies on the same libraries. Might it be a case of old PyGObject installed or something along these lines?

Maybe that could be the case because I believe I was using python 3 but looking for PyGObject I only found it under python2 libs:

/usr/lib/python2.7/dist-packages/PyGObject-3.30.4.egg-info
