iterator Gtk::TextBuffer::insert  ( const iterator&  pos,  const iterator& 
range_begin,  const iterator&  range_end )
Copies text, tags, and pixbufs between range_start and range_end and inserts 
the copy at pos.
If range_start and range_end are in a different buffer from pos then the two 
buffers must share the same tag table.

Overide virtual void Gtk::TextView::on_populate_popup  (Menu*  menu)
but that's just a guess, never tried that myself.

place any widget next to the textview that you find suitable to display that 
info. (maybe a treeview).

As i understand you want to highlight the line over the full width of the 
textview even if the text on that line is not the full width?, i'm not sure 
if that is possible, maybe you should use the treeview widget instead.
