[pygtk] Refresh window

[Genie Fomina]

John, my problem is not about reading from sockets (this part works good),
and I do not have anything that should be done fair amount of time, it's
more about writing into sockets (to two of them I need to write too). I add
sockets by gobject.io_add_watch(sock,gobject.IO_IN | gobject.IO_OUT,
self.my_callback) and so main loop always calls the callbacks because those
sockets are always ready to be written to. So I understand those callbacks
always in pending_events(). And what I have as a result is that one callback
get called all the time when another one never/rarely. Sometimes it works ok
but I need a stable result and I really need to uderstand where is the right
place to put

while/if gtk.events_pending():
    gtk.main_iteration()

Another quesion, is there a way to call a callback to write into a socket
only when I have data to write? Do I have to use io_add_watch method to
write into a socket or it will be better without it?

Thank you, Genie
