I think the obscure function you want is:


     gtk_container_child_set_property ()

(Not to cast aspersions at the developers but some of the function calls 
are truly convoluted, at least to someone not on the development team. 
On the other hand the documentation is superb.)

I don't think there is a really clean way to do this since you can't 
know where the line will break.  My best idea is to set the textview 
background (using a gdk_draw_rgb_image... () call of course.  How could 
you not know this?).  Using the row stride feature it shouldn't be too 
hard.  See the gtk examples (sudo apt-get install gtk2.0-examples) 
program /usr/bin/gtk-demo and the Pixbufs example.
