Hi, Kai:

Thank you so much!
It works with the system browser settings.

By the way, there was typo at my previous e-mail. What I meant was the Qt Webkitwidgets example browser.

Best regards,

It's true that the Qt WebBrowser does still miss a settings dialog for custom proxy settings. Also, it does not feature a UI yet to ask for username and password. Feel free to open a suggestion for this.

Anyhow, it should pick up the system browser settings (http_proxy environment
variable) automatically, as long as you have configured Qt with -system-proxies (default since Qt 5.8).

This is weird, because these are application specific. Anyhow, I'm not sure which application you mean by 'Qt Webwidget Browser'.
