[gtk-2.2.4, but I think this works with earlier 2.x versions]
You have to get a reference to the TreeViewColumn object.
You can do this with:
[http://www.pygtk.org/pygtk2reference/class-gtktreeview.html#method-gtktreeview--get-columns]
my_treeview.get_column(column_num)
or
my_treeview.get_columns()
Then use "set_clickable" to turn off sensitivity:
[http://www.pygtk.org/pygtk2reference/class-gtktreeviewcolumn.html#method-gtktreeviewcolumn--set-clickable]
for col in my_treeview.get_columns():
col.set_clickable(False)
Note that this controls sensitivity only for the column *headers*.
To control the cells, you need to use:
rend.set_property('editable', False)
for each renderer "rend".
