Thanks. Here are a few comments:

- The gtk... namespace for widgets is reserved for the gtk toolkit itself, and should not be used for 3rd party widgets. (Yes, I have done the same mistake myself with my GtkImageViewer widget, but I promise that I will not repeat it!)
- The gdk_draw_... functions are considered obsolete and you should use cairo for drawing instead. (I'm surprised that gtk_paint_polygon is still considered up-to-date though it does not use cairo.) Using cairo will also make the compass more aesthetic, as cairo uses anti-aliasing, which is very noticible for something like a compass that has a lot of angles other than 0 and 90°.
- The contents of the publically viewable _GtkCompass class should preferably be hidden into a private instant.
Regards,
Dov

Dear All,
Not sure if its acceptable list policy (excuse me if its not).
Attached is a simple compass widget. I created this by modifying the dial widget from the tutorial.
I created it for use on my little ketch Wind Roamer. It will be driven by the NMEA app that collects all the boat data available on the NMEA buses (wind direction, course, heading, AIS targets etc). These data will be logged and and displayed on the fore and aft berths allowing the off-watch crew member (there are only two of us!) to keep an eye on things when resting.
Hope its useful to others.
Thanks to the writers of the GTK tutorial.
Leon
