Can't receive download requests from the QWebPage in Qt

Question

I am trying to create a download manager for a QGraphicsWebView and so far it works good except one thing: I cannot send the download request from the QWebPage to the download manager.

QObject::connect(webPage, SIGNAL(downloadRequested(const QNetworkRequest&)),
                 this, SLOT(downloadRequested(const QNetworkRequest&)));

This is my code for connecting the download request signal to the slot that sends the request forward, to the download manager. I put a qDebug() message in the slot before the other actions and the message isn't displayed. This means the signal isn't sent when I click a link to a file.

Is there a way I could send a signal when the user clicks a link to a file?

Answer 1

The downloadRequested(QNetworkRequest) signal is only emitted when you right click on the link, and then click on the "Save link..." item of the context menu.

When the user clicks on a link to something that is supposed to be downloaded (with the HTTP field Content-Disposition: attachment; filename=...), QWebPage emits the unsupportedContent(QNetworkReply*) signal.

Answer 2

Look this: QWebPage::unsupportedContent
