| 44 | \class QDirIterator | - |
| 45 | \inmodule QtCore | - |
| 46 | \brief The QDirIterator class provides an iterator for directory entrylists. | - |
| 47 | | - |
| 48 | You can use QDirIterator to navigate entries of a directory one at a time. | - |
| 49 | It is similar to QDir::entryList() and QDir::entryInfoList(), but because | - |
| 50 | it lists entries one at a time instead of all at once, it scales better | - |
| 51 | and is more suitable for large directories. It also supports listing | - |
| 52 | directory contents recursively, and following symbolic links. Unlike | - |
| 53 | QDir::entryList(), QDirIterator does not support sorting. | - |
| 54 | | - |
| 55 | The QDirIterator constructor takes a QDir or a directory as | - |
| 56 | argument. After construction, the iterator is located before the first | - |
| 57 | directory entry. Here's how to iterate over all the entries sequentially: | - |
| 58 | | - |
| 59 | \snippet code/src_corelib_io_qdiriterator.cpp 0 | - |
| 60 | | - |
| 61 | The next() function returns the path to the next directory entry and | - |
| 62 | advances the iterator. You can also call filePath() to get the current | - |
| 63 | file path without advancing the iterator. The fileName() function returns | - |
| 64 | only the name of the file, similar to how QDir::entryList() works. You can | - |
| 65 | also call fileInfo() to get a QFileInfo for the current entry. | - |
| 66 | | - |
| 67 | Unlike Qt's container iterators, QDirIterator is uni-directional (i.e., | - |
| 68 | you cannot iterate directories in reverse order) and does not allow random | - |
| 69 | access. | - |
| 70 | | - |
| 71 | \sa QDir, QDir::entryList() | - |
| 72 | */ | - |
| 73 | | - |
| 74 | /*! \enum QDirIterator::IteratorFlag | - |
| 75 | | - |
| 76 | This enum describes flags that you can combine to configure the behavior | - |
| 77 | of QDirIterator. | - |
| 78 | | - |
| 79 | \value NoIteratorFlags The default value, representing no flags. The | - |
| 80 | iterator will return entries for the assigned path. | - |
| 81 | | - |
| 82 | \value Subdirectories List entries inside all subdirectories as well. | - |
| 83 | | - |
| 84 | \value FollowSymlinks When combined with Subdirectories, this flag | - |
| 85 | enables iterating through all subdirectories of the assigned path, | - |
| 86 | following all symbolic links. Symbolic link loops (e.g., "link" => "." or | - |
| 87 | "link" => "..") are automatically detected and ignored. | - |
