I have just workarounded by doing this: -import kaa (before importing gtk in my runner script). -kaa.main.run() instead of gtk.main() -kaa.main.stop() instead of gtk.main_quit() I think I get what I am doing this, I am kind of integrating kaa's main loop inside GTK (or calling GTK's from inside kaa?). Anyway, besides these three lines of code I touched, is there any implication for doing this? For example, will gobject.idle_add function keep working?
