cluttermm-1.0: Cairo context problem

[Aarto Matti]

Hello,

I have attached a simple code, please take a look, it just draws a circle. I have two problems and will really appreciate some help on *both* of them.

1. It crashes if I do:

Glib::RefPtr<Clutter::Cairo::Texture> circle = Clutter::Cairo::Texture::create(100, 100);
Glib::RefPtr<Cairo::Context> crmm = circle->create_context();

Of course everything is fine using C API:

ClutterActor *ctex = clutter_cairo_texture_new(100, 100);
cairo_t *cr = clutter_cairo_texture_create(CLUTTER_CAIRO_TEXTURE(ctex));

2. It doesn't work when I try to wrap like this:

Glib::RefPtr<Cairo::Context> crmm(new Cairo::Context::Context(cr, true));

        Glib::RefPtr<Clutter::Actor> circle = Glib::wrap(ctex, true);

        circle->set_position(50, 50);
        stage->add_actor(circle);

        Clutter::main();
