this works fine for a start:
import gobject, zmq
def zmq_callback(self, fd, condition, zmq_socket):
while zmq_socket.getsockopt(zmq.EVENTS) & zmq.POLLIN:
(channel, msg) = zmq_socket.recv_multipart()
return True
....
zmq_fd = zmq_socket.getsockopt(zmq.FD)
gobject.io_add_watch(self.zmq_fd, gobject.IO_IN, self.zmq_callback,
self.zmq_socket)
gtk.main()
