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));

#include <cluttermm.h>
int main(int argc, char** argv)
{
Clutter::init(&argc, &argv);
Glib::RefPtr<Clutter::Stage> stage = Clutter::Stage::get_default();
stage->set_size(200, 200);
stage->set_color(Clutter::Color(0, 0, 0));
stage->show();
// Segfault
/*
Glib::RefPtr<Clutter::Cairo::Texture> circle = Clutter::Cairo::Texture::create(100, 100);
Glib::RefPtr<Cairo::Context> crmm = circle->create_context();
*/
// Doesn't work
/*
Glib::RefPtr<Cairo::Context> crmm(new Cairo::Context::Context(cr, true));
crmm->set_source_rgb(1.0, 1.0, 1.0);
crmm->translate(50, 50);
crmm->arc(0, 0, 50, 0, M_PI * 2);
crmm->fill();
*/
ClutterActor *ctex = clutter_cairo_texture_new(100, 100);
cairo_t *cr = clutter_cairo_texture_create(CLUTTER_CAIRO_TEXTURE(ctex));
cairo_set_source_rgb (cr, 1.0, 1.0, 1.0);
cairo_translate(cr, 50, 50);
cairo_arc(cr, 0, 0, 50, 0, M_PI * 2);
cairo_fill(cr);
cairo_destroy(cr);
Glib::RefPtr<Clutter::Actor> circle = Glib::wrap(ctex, true);
circle->set_position(50, 50);
stage->add_actor(circle);
Clutter::main();
return 0;
}
