class | QDeepCopy< QDir > |
The QDir class provides access to directory structures and their contents in a platform-independent way.
A QDir is used to manipulate path names, access information regarding paths and files, and manipulate the underlying file system.
A QDir can point to a file using either a relative or an absolute path. Absolute paths begin with the directory separator "/" (optionally preceded by a drive specification under Windows). If you always use "/" as a directory separator, Qt will translate your paths to conform to the underlying operating system. Relative file names begin with a directory name or a file name and specify a path relative to the current directory.
The "current" path refers to the application's working directory. A QDir's own path is set and retrieved with setPath() and path().
An example of an absolute path is the string "/tmp/quartz", a relative path might look like "src/fatlib". You can use the function isRelative() to check if a QDir is using a relative or an absolute file path. Call convertToAbs() to convert a relative QDir to an absolute one. For a simplified path use cleanDirPath(). To obtain a path which has no symbolic links or redundant ".." elements use canonicalPath(). The path can be set with setPath(), and changed with cd() and cdUp().
QDir provides several static functions, for example, setCurrent() to set the application's working directory and currentDirPath() to retrieve the application's working directory. Access to some common paths is provided with the static functions, current(), home() and root() which return QDir objects or currentDirPath(), homeDirPath() and rootDirPath() which return the path as a string. If you want to know about your application's path use {QApplication::applicationDirPath()}.
The number of entries in a directory is returned by count(). Obtain a string list of the names of all the files and directories in a directory with entryList(). If you prefer a list of QFileInfo pointers use entryInfoList(). Both these functions can apply a name filter, an attributes filter (e.g. read-only, files not directories, etc.), and a sort order. The filters and sort may be set with calls to setNameFilter(), setFilter() and setSorting(). They may also be specified in the entryList() and entryInfoList()'s arguments.
Create a new directory with mkdir(), rename a directory with rename() and remove an existing directory with rmdir(). Remove a file with remove(). You can interrogate a directory with exists(), isReadable() and isRoot().
To get a path with a filename use filePath(), and to get a directory name use dirName(); neither of these functions checks for the existence of the file or directory.
The list of root directories is provided by drives(); on Unix systems this returns a list containing one root directory, "/"; on Windows the list will usually contain "C:/", and possibly "D:/", etc.
It is easiest to work with "/" separators in Qt code. If you need to present a path to the user or need a path in a form suitable for a function in the underlying operating system use convertSeparators().
Examples:
See if a directory exists.
QDir d( "example" ); // "./example" if ( !d.exists() ) qWarning( "Cannot find the example directory" );
Traversing directories and reading a file.
QDir d = QDir::root(); // "/" if ( !d.cd("tmp") ) { // "/tmp" qWarning( "Cannot find the \"/tmp\" directory" ); } else { QFile f( d.filePath("ex1.txt") ); // "/tmp/ex1.txt" if ( !f.open(IO_ReadWrite) ) qWarning( "Cannot create the file %s", f.name() ); }
A program that lists all the files in the current directory (excluding symbolic links), sorted by size, smallest first:
#include <stdio.h> #include <qdir.h> int main( int argc, char **argv ) { QDir d; d.setFilter( QDir::Files | QDir::Hidden | QDir::NoSymLinks ); d.setSorting( QDir::Size | QDir::Reversed ); const QFileInfoList *list = d.entryInfoList(); QFileInfoListIterator it( *list ); QFileInfo *fi; printf( " Bytes Filename\n" ); while ( (fi = it.current()) != 0 ) { printf( "%10li %s\n", fi->size(), fi->fileName().latin1() ); ++it; } return 0; }
enum QDir::FilterSpec |
This enum describes the filtering options available to QDir, e.g. for entryList() and entryInfoList(). The filter value is specified by OR-ing together values from the following list:
Dirs List directories only. Files List files only. Drives List disk drives (ignored under Unix). NoSymLinks Do not list symbolic links (ignored by operating systems that don't support symbolic links). All List directories, files, drives and symlinks (this does not list broken symlinks unless you specify System). TypeMask A mask for the the Dirs, Files, Drives and NoSymLinks flags. Readable List files for which the application has read access. Writable List files for which the application has write access. Executable List files for which the application has execute access. Executables needs to be combined with Dirs or Files. RWEMask A mask for the Readable, Writable and Executable flags. Modified Only list files that have been modified (ignored under Unix). Hidden List hidden files (on Unix, files starting with a .). System List system files (on Unix, FIFOs, sockets and device files) AccessMask A mask for the Readable, Writable, Executable Modified, Hidden and System flags DefaultFilter Internal flag.
If you do not set any of Readable
, Writable
or Executable
, QDir will set all three of them. This makes the default easy to write and at the same time useful.
Examples: Readable|Writable
means list all files for which the application has read access, write access or both. Dirs|Drives
means list drives, directories, all files that the application can read, write or execute, and also symlinks to such files/directories.
enum QDir::FilterSpec |
enum QDir::SortSpec |
enum QDir::SortSpec |
This enum describes the sort options available to QDir, e.g. for entryList() and entryInfoList(). The sort value is specified by OR-ing together values from the following list:
Name Sort by name. Time Sort by time (modification time). Size Sort by file size. Unsorted Do not sort. SortByMask A mask for Name, Time and Size.
DirsFirst Put the directories first, then the files. Reversed Reverse the sort order. IgnoreCase Sort case-insensitively. LocaleAware Sort names using locale aware compares DefaultSort Internal flag.
You can only specify one of the first four.
If you specify both DirsFirst
and Reversed
, directories are still put first, but in reverse order; the files will be listed after the directories, again in reverse order.
QDir::QDir | ( | ) |
Constructs a QDir pointing to the current directory (".").
QDir::QDir | ( | const QString & | path, |
const QString & | nameFilter = QString::null , |
||
int | sortSpec = Name | IgnoreCase , |
||
int | filterSpec = All |
||
) |
Constructs a QDir with path path, that filters its entries by name using nameFilter and by attributes using filterSpec. It also sorts the names using sortSpec.
The default nameFilter is an empty string, which excludes nothing; the default filterSpec is All
, which also means exclude nothing. The default sortSpec is Name|IgnoreCase
, i.e. sort by name case-insensitively.
Example that lists all the files in "/tmp":
If path is "" or QString::null, QDir uses "." (the current directory). If nameFilter is "" or QString::null, QDir uses the name filter "*" (all files).
Note that path need not exist.
QDir::QDir | ( | const QDir & | d | ) |
Constructs a QDir that is a copy of the directory d.
QDir::~QDir | ( | ) | [virtual] |
Destroys the QDir frees up its resources.
QDir::QDir | ( | ) |
QDir::QDir | ( | const QString & | path, |
const QString & | nameFilter = QString::null , |

int | sortSpec = Name|IgnoreCase , |
||
int | filterSpec = All |
||
) |
QDir::QDir | ( | const QDir & | ) |
virtual QDir::~QDir | ( | ) | [virtual] |
Returns the absolute path name of a file in the directory. Does not check if the file actually exists in the directory. Redundant multiple separators or "." and ".." directories in fileName will not be removed (see cleanDirPath()).
If acceptAbsPath is TRUE a fileName starting with a separator "/" will be returned without change. If acceptAbsPath is FALSE an absolute path will be prepended to the fileName and the resultant string returned.
virtual QString QDir::absFilePath | ( | const QString & | fileName, |
bool | acceptAbsPath = TRUE |
||
) | const [virtual] |
QString QDir::absPath | ( | ) | const [virtual] |
Returns the absolute path (a path that starts with "/" or with a drive specification), which may contain symbolic links, but never contains redundant ".", ".." or multiple separators.
virtual QString QDir::absPath | ( | ) | const [virtual] |
QString QDir::canonicalPath | ( | ) | const [virtual] |
virtual QString QDir::canonicalPath | ( | ) | const [virtual] |
Changes the QDir's directory to dirName.
If acceptAbsPath is TRUE a path starting with separator "/" will cause the function to change to the absolute directory. If acceptAbsPath is FALSE any number of separators at the beginning of dirName will be removed and the function will descend into dirName.
Returns TRUE if the new directory exists and is readable; otherwise returns FALSE. Note that the logical cd() operation is not performed if the new directory does not exist.
Calling cd( ".." ) is equivalent to calling cdUp().
virtual bool QDir::cdUp | ( | ) | [virtual] |
bool QDir::cdUp | ( | ) | [virtual] |
Changes directory by moving one directory up from the QDir's current directory.
Returns TRUE if the new directory exists and is readable; otherwise returns FALSE. Note that the logical cdUp() operation is not performed if the new directory does not exist.
Removes all multiple directory separators "/" and resolves any "."s or ".."s found in the path, filePath.
Symbolic links are kept. This function does not return the canonical path, but rather the simplest version of the input. For example, "./local" becomes "local", "local/../bin" becomes "bin" and "/local/usr/../bin" becomes "/local/bin".
Returns pathName with the '/' separators converted to separators that are appropriate for the underlying operating system.
On Windows, convertSeparators("c:/winnt/system32") returns "c:\winnt\system32".
The returned string may be the same as the argument on some operating systems, for example on Unix.
void QDir::convertToAbs | ( | ) | [virtual] |
Converts the directory path to an absolute path. If it is already absolute nothing is done.
virtual void QDir::convertToAbs | ( | ) | [virtual] |
uint QDir::count | ( | ) | const |
uint QDir::count | ( | ) | const |
Returns the total number of directories and files that were found.
Equivalent to entryList().count().
QDir QDir::current | ( | ) | [static] |
Returns the application's current directory.
Use path() to access a QDir object's path.
static QDir QDir::current | ( | ) | [static] |
QString QDir::currentDirPath | ( | ) | [static] |
static QString QDir::currentDirPath | ( | ) | [static] |
QString QDir::dirName | ( | ) | const [virtual] |
Returns the name of the directory; this is not the same as the path, e.g. a directory with the name "mail", might have the path "/var/spool/mail". If the directory has no name (e.g. it is the root directory) QString::null is returned.
No check is made to ensure that a directory with this name actually exists.

Returns a list of QFileInfo objects for all the files and directories in the directory, ordered in accordance with setSorting() and filtered in accordance with setFilter() and setNameFilter().
The filter and sorting specifications can be overridden using the filterSpec and sortSpec arguments.
Returns 0 if the directory is unreadable or does not exist.
The returned pointer is a const pointer to a QFileInfoList. The list is owned by the QDir object and will be reused on the next call to entryInfoList() for the same QDir instance. If you want to keep the entries of the list after a subsequent call to this function you must copy them.
Note: QFileInfoList is really a QPtrList<QFileInfo>.

QDir QDir::home | ( | ) | [static] |
Returns the home directory.
Under Windows the HOME
environment variable is used. If this does not exist the USERPROFILE
environment variable is used. If that does not exist the path is formed by concatenating the HOMEDRIVE
and HOMEPATH
environment variables. If they don't exist the rootDirPath() is used (this uses the SystemDrive
environment variable). If none of these exist "C:\" is used.
Under non-Windows operating systems the HOME
environment variable is used if it exists, otherwise rootDirPath() is used.

Returns the file name at position index in the list of file names. Equivalent to entryList().at(index).
Returns a QString::null if the index is out of range or if the entryList() function failed.
QString QDir::path | ( | ) | const [inline, virtual] |
Returns the path, this may contain symbolic links, but never contains redundant ".", ".." or multiple separators.
The returned path can be either absolute or relative (see setPath()).
virtual QString QDir::path | ( | ) | const [virtual] |
void QDir::refresh | ( | ) | const |
Refreshes the directory information.
void QDir::refresh | ( | ) | const |
Removes the file, fileName.
If acceptAbsPath is TRUE a path starting with separator "/" will remove the file with the absolute path. If acceptAbsPath is FALSE any number of separators at the beginning of fileName will be removed and the resultant file name will be removed.
Returns TRUE if the file is removed successfully; otherwise returns FALSE.

static QDir QDir::root | ( | ) | [static] |
QDir QDir::root | ( | ) | [static] |
Returns the root directory.

static char QDir::separator | ( | ) | [static] |
virtual void QDir::setFilter | ( | int | filterSpec | ) | [virtual] |
void QDir::setFilter | ( | int | filterSpec | ) | [virtual] |
Sets the filter used by entryList() and entryInfoList() to filterSpec. The filter is used to specify the kind of files that should be returned by entryList() and entryInfoList(). See {QDir::FilterSpec}.
void QDir::setMatchAllDirs | ( | bool | enable | ) | [virtual] |
If enable is TRUE then all directories are included (e.g. in entryList()), and the nameFilter() is only applied to the files. If enable is FALSE then the nameFilter() is applied to both directories and files.
virtual void QDir::setMatchAllDirs | ( | bool | ) | [virtual] |
virtual void QDir::setNameFilter | ( | const QString & | nameFilter | ) | [virtual] |
void QDir::setNameFilter | ( | const QString & | nameFilter | ) | [virtual] |
Sets the name filter used by entryList() and entryInfoList() to nameFilter.
The nameFilter is a wildcard (globbing) filter that understands "*" and "?" wildcards. (See QRegExp wildcard matching.) You may specify several filter entries all separated by a single space " " or by a semi-colon ";".
For example, if you want entryList() and entryInfoList() to list all files ending with either ".cpp" or ".h", you would use either dir.setNameFilter("*.cpp *.h") or dir.setNameFilter("*.cpp;*.h").
virtual void QDir::setPath | ( | const QString & | path | ) | [virtual] |
void QDir::setPath | ( | const QString & | path | ) | [virtual] |
Sets the path of the directory to path. The path is cleaned of redundant ".", ".." and of multiple separators. No check is made to ensure that a directory with this path exists.
The path can be either absolute or relative. Absolute paths begin with the directory separator "/" (optionally preceded by a drive specification under Windows). Relative file names begin with a directory name or a file name and specify a path relative to the current directory. An example of an absolute path is the string "/tmp/quartz", a relative path might look like "src/fatlib".
virtual void QDir::setSorting | ( | int | sortSpec | ) | [virtual] |
void QDir::setSorting | ( | int | sortSpec | ) | [virtual] |
Sets the sort order used by entryList() and entryInfoList().
The sortSpec is specified by OR-ing values from the enum {QDir::SortSpec}.
QDir::SortSpec QDir::sorting | ( | ) | const [inline] |
Returns the value set by setSorting()
SortSpec QDir::sorting | ( | ) | const |
