You shouldn't do that: as indicated by the leading underscore,
_entryWidget is 
an internal field and shouldn't be accessed directly. So upgrading your
Pmw 
version may someday break your code. The portable way to do what you
want is:

NoChoice.configure(entry_state=DISABLED)

or:

NoChoice['entry_state'] = DISABLED

if you prefer this syntax.
