GtkHTML wrap mode?

Hi list, I've been fooling with php-gtk for about a week now and have been enjoying it much: http://code.google.com/p/phpitter/ I've ran in to an issue with GtkHTML though... I noticed in docs that you can set the wrap mode on GtkTextView to by char, instead of by word. But the docs for GtkHTML are seriously lacking compared to the docs for GtkTextView. Is it possible to change the wrap mode? I need it to wrap if someone sends something like "/this/is/a/really/long/path/to/something/so/ha" over twitter. Right now the ui has a minimum length of the longest "word" in your timeline.. :/ Thanks- Ryan
