Given it some thought and a decision made.
The aim behind creating Gnocl is to facilitate the creation of complex layouts. This assumes that the appropriate level or error checking will be made internally and decisions made on how best to proceed based upon the values passed from from the calling script. The answer then is to modify the current buider.c code to detect whether single item or multiple object lists have been received and then to determine which packing call to use, that is either gtk_box_pack_end () or gtk_container_add (). The sequence of items in the list will, by default, be assumed to be the right packing order.
