You'll probably need to go to the editor-canvas% and text% pair (which
is what text-field is built out of). Those objects have all of the
knobs you would probably ever need for things like that. I think you
want, in particular, to `lock' the editor (except when your program is
changing it) and possibly hide the caret with hide-caret .
