Antialias

["Diego A. Fons" <diegofons apexar com ar>]

Hi,

I'm trying to disable the antialias capability when rendering text, 
reading the reference API a wrote this:
       Cairo::FontOptions cairoOpts;
       Glib::RefPtr<Pango::Context> pango;
       Pango::FontDescription font;

       font.set_family("Courier New");
       font.set_size(25000);

       entry1.set_text("texto con AA default");
       entry1.set_size_request(200, 25);
       entry1.modify_font(font);
       pango = entry1.get_pango_context();
       cairoOpts.set_antialias(Cairo::ANTIALIAS_DEFAULT);
       pango->set_cairo_font_options(cairoOpts);

But this code doesn't work :(
Am i doing something wrong? What is the correct way of disabling 
antialias for text?
