ZMQ sockets are not really sockets in that they do not have a file descriptor interface. That is something that is being worked on in the zeromq development, but it is not there yet. Also, I don't think the API will be fully compatible, so I am not sure how it will play with what Qt is expecting. > Just use the qt4 event loop to watch both the file descriptors zeromq wants > to watch, in addition to whatever events qt4 needs.
