Maybe have a look at the widgets I have adapted here: http://sourceforge.net/p/lives/code/1810/tree/trunk/src/giw/ giwknob, giwvscale and giwled. They will work with both gtk+ 2 and gtk+ 3. If you look at the #if GTK_CHECK_VERSION lines it will give you an idea of exactly what needs to be changed. The biggest change is using cairo for drawing, but there are some smaller changes like GtkObject becomes GObject, etc. It took me a while and a lot of trial and error, so it may save you some time. giwtimeline is only for gtk3, so it represents a somewhat cleanish implementation. Some of the support functions are found in http://sourceforge.net/p/lives/code/1810/tree/trunk/src/widget-helper.c I can't guarantee that any of this adheres to the official coding standards. Hope this helps !
