Such a widget would be nice, but I know that it is much work to make a really fine one. You intend to use plain C? A Questions is, if cairo drawing is fast enough in all cases. For my app http://ssalewski.de/PetEd.html.en it is fast enough, but I tried hard to draw new only what is really necessary. (And it is not only slow because I choosed Ruby language, performance is really restricted by cairo, but maybe I will be able to further improve performance.) You may also have a look at https://gitlab.com/ivor/GTK3-Cairo it was recently mentioned on gtk-list, but I had no time to look at that one. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
