Hi,

I am doing this:

 // this on header

 Class Classe...{
   ...
   bool Expose(GdkEventExpose* Event);
   int  Draw_Line(Gtk::TreePath Path, Glib::RefPtr<Gdk::Window> 
&Window, Glib::RefPtr<Gdk::GC> &GC, Gtk::TreeViewColumn* &Column, 
Gdk::Rectangle &Master, Gdk::Rectangle &Rectangle, bool Draw);
   ...
 };

 // this on body

 Classe::Classe(...){
   ...
   m_Grid.signal_expose_event().connect(SigC::slot(*this, 
&Classe::Expose), /*after=*/true);
   ...
 }

 int Classe::Draw_Line(Gtk::TreePath Path, Glib::RefPtr<Gdk::Window> 
&Window, Glib::RefPtr<Gdk::GC> &GC, Gtk::TreeViewColumn* &Column, 
Gdk::Rectangle &Master, Gdk::Rectangle &Rectangle, bool Draw){
   int MaxH = 0;
   if (!m_TreeModel->get_iter(Path))
     return 0;
   m_Grid.get_background_area(Path, *Column, Rectangle);
   while (m_TreeModel->get_iter(Path) && Rectangle.get_y()<0){
     Path.next();
     m_Grid.get_background_area(Path, *Column, Rectangle);
   }
   Path.prev();
   m_Grid.get_background_area(Path, *Column, Rectangle);
   do{
     if (Draw)
       Window->draw_line(GC, Master.get_x(), Rectangle.get_y(), 
Master.get_x()+Master.get_width(), Rectangle.get_y());
     if (m_Grid.row_expanded(Path)){
       Path.down();
       MaxH = Draw_Line(Path, Window, GC, Column, Master, Rectangle);
       Path.up();
     }
     Path.next();
     m_Grid.get_background_area(Path, *Column, Rectangle);
   } while (m_TreeModel->get_iter(Path) && 
Rectangle.get_y()<=Master.get_height());
   Path.prev();
   m_Grid.get_background_area(Path, *Column, Rectangle);
   if (Rectangle.get_y()+Rectangle.get_height()<=Master.get_height()){
     if (MaxH < Rectangle.get_y()+Rectangle.get_height())
       MaxH = Rectangle.get_y()+Rectangle.get_height();
     if (Draw)

Master.get_x()+Master.get_width(), 
Rectangle.get_y()+Rectangle.get_height());
   }
   else
     MaxH = Master.get_height();
   return MaxH;
 }

 bool Classe::Expose(GdkEventExpose* Event){
   int i, MaxH=0, MaxW;
   Gdk::Rectangle Master;
   m_Grid.get_visible_rect(Master);
   if (Master.get_height()<3 || Master.get_width()<3)
     return false;
   Gtk::TreeViewColumn *Column = m_Grid.get_column(0);
   if (!Column)
     return false;
   Glib::RefPtr<Gdk::Window> Window = m_Grid.get_bin_window();
   Glib::RefPtr<Gdk::GC> GC = Gdk::GC::create(Window);
   Gdk::Rectangle Rectangle;
   Gtk::TreePath Path("0");
   MaxH = Draw_Line(Path, Window, GC, Column, Master, Rectangle);

     Window->draw_line(GC, Rectangle.get_x(), 0, Rectangle.get_x(), MaxH);

   }
   Window->draw_line(GC, Rectangle.get_x(), 0, Rectangle.get_x(), MaxH);
   return false;
