	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.
