/* this is a wrapper around t_fielddesc-- it adds a flag for two reasons:
   1) tkpath defaults to inheriting values for options from the parent until
      you specify them-- after that, there's no way to get back to "inherit".
      We set the flag to "0" to mean "inherit"-- that way we don't send a tcl
      string for that option.  There's still the bug that the user can't set
      an attribute back to "inherit" after they've set something explicitly,
      however.
1114
1115
1116
   2) This might be generally useful even with other GUI toolkits, so that if
      the user calls a method for an attribute without any arguments, Qt goes
      back to inheriting the value from the parent.  That gives us a way to
1117
1118
1119
      differentiate "inherit" from fielddescriptors, the value "none" and
      "".  (Similar to the way "set" resets a message box.)
