gio:list-model-item (model pos)

model -- a g:list-model object
pos -- an unsigned integer with the position of the item to fetch

The g:object instance at pos.

Get the item at pos. If the pos argument is greater than the number of items in the list model, nil is returned. The nil value is never returned for an index that is smaller than the length of the list model. See the g:list-model-n-items function.
