It also supports listing + directory contents recursively, and following symbolic links. Unlike + QDir::entryList(), QFileSystemIterator does not support sorting. + + The QFileSystemIterator constructor takes a QDir or a directory as + argument. After construction, the iterator is located before the first + directory entry. Here's how to iterate over all the entries sequentially: + + \snippet doc/src/snippets/code/src.corelib.io.qdiriterator.cpp 0 + + The next() function returns the path to the next directory entry and + advances the iterator. You can also call filePath() to get the current + file path without advancing the iterator. The fileName() function returns + only the name of the file, similar to how QDir::entryList() works. You can + also call fileInfo() to get a QFileInfo for the current entry. + + Unlike Qt's container iterators, QFileSystemIterator is uni-directional (i.e., + you cannot iterate directories in reverse order) and does not allow random + access. + + QFileSystemIterator works with all supported file engines, and is implemented + using QAbstractFileEngineIterator. + + \sa QDir, QDir::entryList(), QAbstractFileEngineIterator +*/ + +/*! \enum QFileSystemIterator::IteratorFlag + + This enum describes flags that you can combine to configure the behavior + of QFileSystemIterator. + + \value NoIteratorFlags The default value, representing no flags. The + iterator will return entries for the assigned path. + + \value Subdirectories List entries inside all subdirectories as well. + + \value FollowSymlinks When combined with Subdirectories, this flag + enables iterating through all subdirectories of the assigned path, + following all symbolic links.
