Hi Jeff,
I don't think you're correct on this point.

This is an upstream bug in Tk which appears to still be present in their
development version. There's supposed to be a "-state" property of
treeview columns, but the "-" is missing. Python always removes the
first character in its configure-type interfaces, so you get "tate"
The ttk widgets handle some things differently than the standard Tk
widgets. According to the man page (of Tk 8.5 at
http://www.tcl.tk/man/tcl8.5/TkCmd/ttk_treeview.htm, with the ttk
widgets, "state" is a command rather than a configuration option:
pathname state ?stateSpec?
Modify or query the widget state; see ttk::widget(n).
Therefore, rather than Tk being wrong, Python is doing the wrong thing
by mangling the command.
Compare the definition of "-text" to "state" at lines 296 and 308:
http://tktoolkit.cvs.sourceforge.net/viewvc/tktoolkit/tk/generic/ttk/ttkTreeview.c?revision=1.41&view=markup#l295
For what it's worth, here is the core repo for Tcl/Tk now:
http://core.tcl.tk. The project shifted its SCM from CVS to Fossil
(http://fossil-scm.org/) about a year ago.
I do understand the confusion. In the ttk widget C code, "state" is
grouped among the configuration options, and its purpose is to set
configuration, but it does so as a command, not as a flag passed to the
"configure" command. I'm not sure why it was implemented this way, but
that does appear to be its design. Perhaps someone should file a bug
against Python to make sure it's implemented correctly in Tkinter?
