Cannot download pdf from QML webview

I've developed a page in my app that uses QML webview and that points to an online site contaning links to some PDF files.

I was expecting the PDF to download correctly but when the user clicks on the link nothing happens.

QML webview is, AFAIK, the only usable solution in mobile environments (Android and iOS).

Is there a solution or a workaround to download and display a PDF from that webview?

Thanks.
