J- you hit the nail on the head! 

to the rest, beleive me i've scowerd the tcl/tk docs. i don't have any
problem editing the value of the TkText widget via the methods you-all
have now relayed to me. thanks for the attempt though. that's just not
the problem. what i want to do is directly bind a variable to the
widget, a la -textarea, in order to create a mixin module that links an
object to a form --instantly. so if the object changes, the form
changes, and vice-versa. well, at least that was the hope. now it looks
like i'll have to settle on some sort of 'refresh form' method. that is
unless anyone else has thought of way....

i still wonder if a ruby callback of some sort could pull it off. is
there a way to callback on method invocations?

p.s. by the way, mike, i'm not a newbie
