Hi, out of curiosity and as a proof of concept I hacked the very beginning of a QT widget wrapper. It's tested on linux and a somewhat older gcj/libgcj combination. You may want to try it following these directions: 1. Download http://www.informatik.fernuni-hagen.de/import/pi3/joerg/gcj/qt.tar.gz 2. Download QT 2.0.1 3. Edit the *.sh and adjust the paths 4. Type make 5. Run ./QTest The sample application will ask for a zip file whose contents is displayed in a QListBox. Cheers, Jörg
