What is up? GtkWidget is a subclass of GObject (of course not in C++ sense, but in GObject type system). The line gobject=(GObject *)gtk_window_new(GTK_WINDOW_TOPLEVEL); contains nothing that could produce the errors above (unless something else is seriously messed up). Try to create a minimal test case that reproduces the errors, you should find the real source of the problem along the way -- if not, post it. Yeti -- That's enough. _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
