Dear all, thanks a lot for all your comments, I played a little bit with cario and it works out quit well: http://www.pagelnet.de/tmp/pinion.png
Looks much better then my trails with gtkextra and the polar plot. Since most examples I found where based on GTK3 I moved also to GTK3 for this test. So the reset of the applications have to follow now, but its anyway time... regards Arne _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
