- Remove unneeded member variables. - Use new connection syntax. - Streamline code. - Add a QCheckBox for launching the file after download and make the default file name and download directory configureable. - Make status messages more verbose. - Set Password echo mode on authentication dialog. - Extract the progress dialog to a separate class that is directly connected to the QNetworkReply, which is created on demand. Set set minimum and duration on it. This fixes a crash that currently occurs when clicking "Abort" on the SSL error dialog and "Cancel" on the progress dialog that is then re-shown due to its internal force timer/minimum duration handling. - Resize according to screen size. Task-number: QTBUG-48332 Change-Id: Ia2611e63fe96d6f49e4cdd06049a206ddb2c2864 Reviewed-by: David Faure <david.faure@kdab.com>
