Hi, I am not a GAMBAS expert as I did start to use it on the past January, any how I made a small graphic project that can be usefull to somebody as an example. It rapresents an analogic tuning scale of a radio. It is downloadable from http://www.qsl.net/zp4kfx/Linux/Dial-0.0.1.tar.gz Improvements and comments are welcome. Regards Pino
