The reason why this is not going to work (for the windows theme at 
least, GTK+ 2.10) is a hard-coded check on the type of widget->parent in 
draw_box() on line 1929 of msw_style.c:

       if (GTK_IS_TREE_VIEW (widget->parent)
       || GTK_IS_CLIST (widget->parent))
       {
           if (xp_theme_draw
           (window, XP_THEME_ELEMENT_LIST_HEADER, style, x, y,
            width, height, state_type, area))
           return;
