The window parameter is a window identifier. The listtag parameter is a checkable outline list listtag (case sensitive). The row parameter is an offset into listtag (starting from one). The checkstate parameter indicates the state the check box for the list entry should take. (0 indicates no check, 1 indicates a check).
