        If you are reading the information from a
file, it is easy enough: 
        
        <pseudo code>
        read_line_from_file ()
        gtk_entry_set_text (GTK_ENTRY (text_entry), line);
        while (g_main_context_iteration(NULL, FALSE));
        </pseudo code>

        if you are waiting of a socket, or a fifo, or the like, I would do the
following:

        <pseudo code>
        while (1) {
                select (n, socket_fd_set, NULL, NULL, timeout)
                if (socket_ready_to_read) {
                        read_from_socket ()
                        gtk_entry_set_text (GTK_ENTRY (text_entry), line);
                }
                if (socket_closed)
                        break;
                while (g_main_context_iteration (NULL, FALSE));
        }
        </pseudo code>

        of course, what other users have suggested (using a textview instead of
an entry) is also a good idea.
