gio:list-store-find (store item)

store -- a g:list-store object
item -- a g:object item

The unsigned integer with the first position of the item, if it was found, otherwise nil.

Looks up the given item in the list store by looping over the items until the first occurrence of item. If the item argument was not found, then this method will return nil.

If you need to compare the two items with a custom comparison function, use the g:list-store-find-with-equal-func function with a custom g:equal-func-full callback function instead.
