When you do a, b, c = runtime.shamir_share(range(1, n+1), Zp, my_input) you can attach callbacks to the three shares. If self.pbar is a gtk.ProgressBar something like this should do the trick: self.shares = 0 def step(value): self.shares += 1 self.pbar.set_fraction(self.shares / float(n)) return value a.addCallback(step) b.addCallback(step) c.addCallback(step) The idea is to make the callback update the progress bar, but otherwise pass the value through unharmed. -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multiparty Computation) to Python.

I would go for PyGTK, which has a Twisted integration available: http://twistedmatrix.com/projects/core/documentation/howto/choosing-reactor.html#auto11 This is important in order to be able to run both the network and graphical event loops. I once played with it, please see viff/apps/double-auction/client.py for a simple program that uses PyGTK with Twisted. It doesn't do anything VIFF related, though. In order to actually do something VIFFy with it, I imagine you would have a button with a callback like this: def start_clicked(): r = create_runtime(...) r.addCallback(go) The go function could then let one of the players input a number: def go(runtime): if runtime.id == 1: x = int(some_input_field.text) else: x = None x = runtime.shamir_share([1], Zp, x) y = x * x z = runtime.open(y) z.addCallback(update_output) Here I guess a text input field in GTK has a text attribute... Finally, update_output would do: def update_output(output): some_label.text = "Shared number: %d" % output.value I talked about this with Tomas Toft just the other day, so maybe he can contribute more to the pseudo-code :-) There were a slightly tricky issue with the synchronization of program counters that we had to think about, but now I don't remember the details.

[viff-devel] GUI programming for Python/VIFF
Hi! I'm developing a small application that will use VIFF. Instead of inputting values through the command line I would like to create a simple graphical interface. Have anyone experience with such GUI toolkits? Any recommendations? - I've barely tested PyQt, but it has some dual commercial/GPL license that I probably want to avoid. - Tkinter is the "standard" GUI toolkit for Python, but is reported to have a non-native look and feel. - wxPython is maybe the most popular GUI toolkit for Python, so perhaps I give it a try.
