Hi and welcome to devnet,

That's a question you should bring to the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

I'll give it a try. I've got a client wanting plugins for FF, Chrome, Safari, and IE. All are somewhat easy (manifest text file + some XML, HTML, Javascript, jQuery) except for IE. On IE, one STILL (yep, disappointing that Microsoft doesn't run with the pack yet) requires that you compile it into a COM object DLL and then through some registry stuff, hook it into IE. (BTW, the new experimental Edge browser from Microsoft has no extension support yet. Windows 10 comes with both Edge and IE11.)

sslConfiguration

You don't seem to have actually associated the sslConfiguration object with the QSslSocket object.

You can set the cert/key files directly on the QSslSocket if that helps simplify your code for testing...

Yes you have everything you need in Qt to do that, however there are other projects like QHttp that you could use directly.

Hope it helps

Yes, thanks.
I found this example. And he is works.

And I found - Webengine is not supported on android and not with MinGW either.

There is some additional information on this issue in the JIRA at https://bugreports.qt.io/browse/QTBUG-45122
