Well I've understood that I must add columns in this way: nautilus_column_new(ID, ATTRIBUTE, LABEL, DESCRIPTION);
what scares me is that ATTRIBUTE must be understood by get_string_attribute(NautilusFileInfo* file, const char* ATTRIBUTE) I see that there is a add_string_attribute(NautilusFileInfo *file, const char *attribute_name, const char *value) So it should be that someone must call this function when listing the files inside a directory. Where does this happen? Thank you very much for your help! I hope I will release this patch thanks to you! -- nautilus-list mailing list nautilus-list@gnome.org http://mail.gnome.org/mailman/listinfo/nautilus-list
