Used to indicate which fields of a gdk:geometry instance should be paid attention to. Also, the presence/absence of the :pos, :user-pos, and :user-size values is significant, though they do not directly refer to gdk:geometry fields. The :user-pos value will be set automatically by the gtk:window widget if you call the gtk:window-move function. The :user-pos and :user-size values should be set if the user specified a size/position using a - geometry command-line argument. The gtk:window-parse-geometry function automatically sets these flags.
