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]

Thanks, that’s exactly what I needed.
