[Interest] Use Qt to zip / unzip files on iOS, Android, OS X, & Windows ?

[Edward Sutton]

Andy, thanks for sharing the article.

On second thought we do not need ZIP file compatibility.  We just need to reduce data size of XML to speed up data transfers over Bluetooth.

We are going to try using the QByteArray compress functions.

I don't know if it's useful or not, but years ago I wrote a little in-memory zip class you might be able to modify or build on.  It uses minizip.

I think I have a more fleshed-out version somewhere.  If it's of interest I can try to find it and dust of the decaying bits :-)

Is there a solution in Qt 5.6 LTS ?

Else maybe a 3rd party lib such as QuaZip is good?
