I only know two ways round this, both of which involve you writing some
kind of string splitter.
a) Do the whole darn thing and write a splitter that breaks the string as
you want it.
or
b) Break the string into words and use
for j=0, n_words-1 do $
WIDGET_CONTROL, textid, SET_VALUE=word(j), /append, /no_newline
This will break the string provided YSIZE > 1.
