Print CGAL arrangement with Qt

Question

I am using a CGAL Arrangement.

Here is my Arrangement_2 type:

typedef CGAL::CORE_algebraic_number_traits              Nt_traits;
typedef Nt_traits::Rational                             Rational;
typedef Nt_traits::Algebraic                            Algebraic;
typedef CGAL::Cartesian<Rational>                       Rat_kernel;
typedef Rat_kernel::Point_2                             Rat_point_2;
typedef Rat_kernel::Segment_2                           Rat_segment_2;
typedef Rat_kernel::Circle_2                            Rat_circle_2;
typedef CGAL::Cartesian<Algebraic>                      Alg_kernel;
typedef CGAL::Arr_conic_traits_2<Rat_kernel, Alg_kernel, Nt_traits> Traits_2;
typedef Traits_2::Point_2                               Point_2;
typedef Traits_2::Curve_2                               Conic_arc_2;
typedef CGAL::Arrangement_2<Traits_2>                   Arrangement_2;

I would like to know how can I print this Arrangement_2 in a Qt window. I would really appreciate an example.

Have a look at the code of the Qt demo in demo/Arrangement_on_surface_2, in the CGAL tarball. There should be everything you need.
