Are you drawing using GDK API instead of Cairo? Are you implementing your own widgets? Are you using GdkWindow API, or using things like foreign surfaces? You can start from the migration guide from 2.x to 3.x: https://developer.gnome.org/gtk3/stable/gtk-migrating-2-to-3.html And if you want to look at what changes are necessary to go from 3.x to 4.0, you can look at the migration guide: https://gnome.pages.gitlab.gnome.org/gtk/gtk/gtk-migrating-3-to-4.html Just a word of caution: GTK 4.0 is not out yet, and there are still some changes that are in the pipeline, especially because GNOME applications are now in the process of experimental ports to the 4.0 API, and we're addressing the feedback. My strong suggestion is to port to GTK 3.x, and use the 3.x-to-4.x migration guide to ensure that you're using modern API that can ease the transition toward 4.0 when it's released. Ciao, Emmanuele.
