gtk:list-store-insert-after (model sibling)

model -- a gtk:list-store object
sibling -- a valid gtk:tree-iter, or nil

The gtk:tree-iter iterator to the new row.

Inserts a new row after sibling. If sibling is nil, then the row will be prepended to the beginning of the list. The returned iterator will point to this new row. The row will be empty after this function is called. To fill in values, you need to call the gtk:list-store-set or gtk:list-store-set-value functions. The gtk:list-store implementation is deprecated since 4.10. Use the g:list-store object instead.
