Proper way to provide gtk+ app with asynchronous data?

["Dmitry M. Shatrov" <zzidre mail ru>]

Hello.

I'm going to display graphically data that arrives from another machine.
It must be displayed as soon as possible, so periodic polling
does not suite my needs.
How to implement this properly?

In my case there is one thread which receives data and an UI thread with
an event loop, I think about making a new event source (g_source_new, I
mean),
is it correct or maybe there's a simpler solution?

Thank you.
