QWebEngine: print a page?

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?

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.

Qt 5.7 includes print support in to pdf files for QWebEngine.

Use printToPdf function to export the current page in a pdf file. Example:

const QString fileName = QFileDialog::getSaveFileName(0,
                                                tr("Save pdf"),
                                                ".",
                                                tr("PDF Files (*.pdf)"));
if (fileName.isEmpty()) {
    return;
}
ui->webView->page()->printToPdf(fileName);

I would offer following code (for a while):

    QTextEdit *textEdit = new QTextEdit;
    ui.myWebView->page()->toHtml([textEdit](const QString &result){ textEdit->setHtml(result); });
    textEdit->print(somerinter);
    textEdit->deleteLater();
