c++ - QWebEngine: print a page?

Question

The migration from QWebKit to QWebEngine seems to be much more complicated than Qt guys claimed. With QWebKit I could print a webpage easily via

QWebView->print(&printer);

With QWebEngine class QWebEngine view does not provide a method print(). Their browser example uses a class named QWebEngineFrame which offers a method print() - but the whole QWebEngineFrame is not defined anywhere!

So my question: how do I print a page using QWebEngine?

Answer 1

I think the correct way to use QWebEngineView::render method because QWebEngineView is a QWidget. It accepts paint device as a first argument and you may pass QPrinter there for printing.

Update: If you can use the latest version of Qt, in Qt 5.8 a new function for printing page was added:

void QWebEnginePage::print(QPrinter *printer, FunctorOrLambda resultCallback);

Actually it first prints to temp PDF with QPrinter settings.

Here is the link to Qt docs.
