Actually there is another method that I use that has the same effect.

procedure KeyPress_RE(integer self, integer event, sequence parms)
	if equal(getUserProperty(self, "ReadOnly"), {True}) then
		returnValue(-1)
      end if
end procedure
setHandler(RE, w3HKeyPress, routine_id("KeyPress_RE"))
defineUserProperty(RE, "ReadOnly", False)

. . . if NeedsReadOnly then
       setUserProperty(RE, "ReadOnly", True)
   end if
