Neither of these functions checks for the existence of files or directory they only construct paths. The filePath() function returns a path to the specified file or directory relative to the path of the QDir object absoluteFilePath() returns an absolute path to the specified file or directory.

Paths to files and directories within a directory can be constructed using filePath() and absoluteFilePath(). If you need information about each entry, use entryInfoList() to obtain a list of QFileInfo objects. A string list of the names of all the entries in a directory can be obtained with entryList(). The number of entries in a directory is returned by count(). Files and Directory Contentsĭirectories contain a number of entries, representing files, directories, and symbolic links. The refresh() function re-reads the directory's data from disk. You can test for the presence of a directory with a given name by using exists(), and the properties of a directory can be tested with isReadable(), isAbsolute(), isRelative(), and isRoot(). cd('.') is equivalent to cdUp().ĭirectories can be created with mkdir(), renamed with rename(), and removed with rmdir(). The cdUp() function changes the directory of the QDir object so that it refers to its parent directory i.e. When cd() is called with the name of an existing directory, the QDir object changes directory so that it represents that directory instead.

The path for a directory can also be changed with the cd() and cdUp() functions, both of which operate like familiar shell commands. SetNameFilters(const QStringList & nameFilters) Rename(const QString & oldName, const QString & newName)
