Tk Text box

Is there any way I can create a text box in Tk that the user cannot
edit, but the program can edit the value of? I have tried doing state
('disabled') on a TkText but this makes it not editable at all.

Also, is there a way I can bind an event to someone hitting enter in a
TkEntry?

Remove its classs from the bindtags of the widget.
Probably, it is the most simple way.
For example,

t = TkText.new
t.bindtags -= [t.class]

e = TkEntry.new
e.bind('Return'){ ... callback operation ... }
