I recall writing some code, for this very mailing list, once upon a  
time...  but i cannot find it.  Alas.  Anyway, the trick was to, in  
the textview's size-allocate, check whether the allocated space for  
the widget is wider than the desired wrap width, and, if so, adjust  
the textview's right margin to make up the difference.  This required  
measuring a string, which assumed you are using a monospaced font.   
If the window is narrower than the wrap width, it had to set the size  
request of the textview such that the scrolled window would activate  
the horizontal scrollbar.

I cannot find this code.  :-/

However, that suggestion should give you something to experiment with.


(By the way, SourceView has the nice feature to show the right  
margin, but you'll have to set the property yourself to make the  
wrapping honor it.)
