Still you have to react on deprecations better soon than later, if you
want to avoid drowning some day.

Oh, from reading this thread I thought this would be the case, but
apparently it is not. Seems you really can change the orientation of
some Gtk[HV]Box now. Shocking.

Maybe GtkBox and friends should get an internal flag for locking that
property? Whilst changing the orientation of widgets can be useful under
certain circumstances, there are others where you don't want to permit
this. Well, but maybe I think too restrictive right now, as you can do
nonsense to derived widgets already. Thinking about evil actions like
calling gtk_container_remove() on some essential child.

Ciao,
