Hi, I am not active in Vala coding right now, but I still read the digest. For all kinds of useful reasons, just like your "passing around the main window" — have a look into a thing called "pubsub", or "Publish Subscribe." It's not a library, it's an idea. Once you get it, you will wonder how you ever lived without it! Good luck, /d _______________________________________________ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
