Hi, I´m currently trying to modify the Gtk-- signal/slot mechanism for Penguinplay. It should fit neatly as our OO event mechanism. See http://www.cs.tut.fi/~p150650/gtk/gtk--.html for details on it. Please let me know what you think about adopting it (so that I don´t waste too much time/effort in case you´re against it ;) Cu Christian
