Any ideas on this one? I'm getting this printed on every call to add a page to a GtkNotebook, although the pages are added OK and the notebook displays fine: (hcpgui.exe:3628): Gtk-CRITICAL **: gtk_container_foreach: assertion `GTK_IS_CONTAINER (container)' failed The assertions are printed when gtk_notebook_append_page is called in the following sequence: viewWin = gtk_scrolled_window_new(NULL, NULL); . noteBook = gtk_notebook_new(); lbl = gtk_label_new("some text"); gtk_notebook_append_page(GTK_NOTEBOOK(noteBook), viewWin, lbl); Ian _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
