Doesn't compile against gtk4 master (GtkEntry)
Hi, I happened to be trying to build gnome-todo as part of trying out Builder, and found it didn't compile because of Gtk4 API changes.
I changed enough to make it compile and launch, but I really don't know how right it is. I've actually never used gnome-todo.
Anyway, changes are pushed to a fork, in the hope they might be useful: undeconstructed/gnome-todo@5ffddb81
