Thanks for your answer!

My function looks now like this:

Gtk::DrawingArea* tmp=(Gtk::DrawingArea*)refXml->get_widget("DrawingArea");
Glib::RefPtr<Gdk::Window> window(tmp->get_window());
	
window->draw_arc(tmp->get_style()->get_fg_gc[tmp->get_state()],
				 TRUE,
				 0, 0, 550,550,
				 0, 64 * 360);

Unfortantly I still have problems:

g++ $(pkg-config --libs --cflags gtkmm-2.4) $(pkg-config --libs --cflags
libglademm-2.4) main.cc
main.cc: In function 'bool do_draw(GdkEventExpose*)':
main.cc:31: error: invalid types '<unresolved overloaded function
type>[Gtk::StateType]' for array subscript

Line 31 is the "window->draw_arc" line.
