There are a couple of difficulties I see. They are not
insurmountable, just tedious. The case I have I do not
know the text beforehand, it is read from a file. Also
in order to insert the line breaks in a good spot I would
have to use the same algorithm the text widget must use
because the font is perportional. If I have to do that I
could just count the \n's I would insert, but not insert
them, then I would know how many lines were used.
I guess I will look at the text widget again. It is pretty
big and I couldn't figure out exactly where the word wrap
stuff was calculated. I may try to change the text widget so
this information is accessable. I can't be the only person
who would need this, can I?
