Solved How to cache username/password in QWebView

[xiazeyi]

I write some HTML code using iframe to load a website in QWebView widget, and the website requires sign in by inputting username and password. The problem is that I have to sign in every time. Is there any solution to cache the account information?
Like some browsers, it will ask whether to save username and password when a form containing account information is submitted.

Seems that using a global QNetworkAccessManager can resolve this problem.
