Hmm, I think however that the usage of "state" in the heading command, where you can do e.g.: % .t heading 0 -anchor e state disabled -text foo is probably at least rather counter-intuitive even for tcl programmers. In this context "state" (at least to me) clearly looks like an option, not like a command and should therefore be preceded by a "-". And since the state option for the heading command is not documented in the treeview man page its behavior might still be a subject to be changed, so I doubt if it makes much sense to add a workaround to ttk.py now.
