Using QWebEngine to login to a page.

[anda_skoa]

I tried using this approach but was unsuccessful. Here is the link of the login page I am trying to automatically log into.

In thise case the server doesn't ask for regular authentication but presents you with a form.
You will have to programatically fill the form and submit it.

Now code below is my slot with the authenticator and know that this slot can't possibly work

No, that slot looks ok.

How can I send the username and password to the server?

That's what the authenticator does once the signal emit has returned.
I.e. the engine sees the authentication request, it creates an authentication object, emits a pointer to it in a signal, the slot fills in the data, the code after the signal emit uses the data.

A web page using a standard authentication request would have worked with that.

Cheers,
