This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Returns a list of the names of all the files and directories in the directory, ordered according to the name and attribute filters previously set with setNameFilters() and setFilter(), and sorted according to the flags set with setSorting().
The attribute filter and sorting specifications can be overridden using the filters and sort arguments.
Returns an empty list if the directory is unreadable, does not exist, or if nothing matches the specification.
