GtkTreePaths do not know anything about underlying model (number of elements, ...), which means that it's always possible to obtain next path. Whether this new path corresponds to anything inside model is beyond the scope of path itself (you'll check this when obtaining iter from this path). On the other hand, previous path cannot be obtained if your current path already points to first element (the one with index 0) and this is what gtk_tree_path_prev() reports with it's return value. > And is the last sentence proper English? :-) As long as I'm able to understand you, I really don't care much;) Tadej -- Tadej Borovšak tadeboro.blogspot.com [email protected] [email protected] _______________________________________________ gtk-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtk-list
