Display the message box to ask the question, e.g. via https://doc.qt.io/qt-5/qmessagebox.html#question. Then save or not according to response.
Or use QFileDialog to allow the user to pick a filename/path to save to, https://doc.qt.io/qt-5/qfiledialog.html#getSaveFileName. But not if you are wanting to control the filename/path, as per the filename code you are using.
