DESCRIPTION
       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.

       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.

       If you need the path in a form suitable for 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;
	   }

   Member Type Documentation
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:

       QDir::Dirs - List directories only.

       QDir::Files - List files only.

       QDir::Drives - List disk drives (ignored under Unix).

       QDir::NoSymLinks - Do not list symbolic links (ignored by operating systems that don't
       support symbolic links).

       QDir::All - List directories, files, drives and symlinks (this does not list broken
       symlinks unless you specify System).

       QDir::TypeMask - A mask for the the Dirs, Files, Drives and NoSymLinks flags.

       QDir::Readable - List files for which the application has read access.

       QDir::Writable - List files for which the application has write access.

       QDir::Executable - List files for which the application has execute access. Executables
       needs to be combined with Dirs or Files.

       QDir::RWEMask - A mask for the Readable, Writable and Executable flags.

       QDir::Modified - Only list files that have been modified (ignored under Unix).

       QDir::Hidden - List hidden files (on Unix, files starting with a .).

       QDir::System - List system files (on Unix, FIFOs, sockets and device files)

       QDir::AccessMask - A mask for the Readable, Writable, Executable Modified, Hidden and
       System flags

       QDir::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: 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.

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:

       QDir::Name - Sort by name.

       QDir::Time - Sort by time (modification time).

       QDir::Size - Sort by file size.

       QDir::Unsorted - Do not sort.

       QDir::SortByMask - A mask for Name, Time and Size.

       QDir::DirsFirst - Put the directories first, then the files.

       QDir::Reversed - Reverse the sort order.

       QDir::IgnoreCase - Sort case-insensitively.

       QDir::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.

MEMBER FUNCTION DOCUMENTATION
QDir::QDir ()
       Constructs a QDir pointing to the current directory.

       See also currentDirPath().

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":

	   QDir d( "/tmp" );
	   for ( int i = 0; i < d.count(); i++ )
	       printf( "%s\n", d[i] );

       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.

       See also exists(), setPath(), setNameFilter(), setFilter(), and setSorting().

QDir::QDir ( const QDir & d )
       Constructs a QDir that is a copy of the directory d.

       See also operator=().

QDir::~QDir () [virtual]
       Destroys the QDir frees up its resources.

QString QDir::absFilePath ( const QString & fileName, bool acceptAbsPath = TRUE ) const [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.

       See also filePath().

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.

       See also setPath(), canonicalPath(), exists(), cleanDirPath(), dirName(), and
       absFilePath().

       Example: fileiconview/qfileiconview.cpp.

QString QDir::canonicalPath () const [virtual]
       Returns the canonical path, i.e. a path without symbolic links or redundant "." or ".."
       elements.

       On systems that do not have symbolic links this function will always return the same
       string that absPath() returns. If the canonical path does not exist (normally due to
       dangling symbolic links) canonicalPath() returns QString::null.

       See also path(), absPath(), exists(), cleanDirPath(), dirName(), absFilePath(), and
       QString::isNull().

bool QDir::cd ( const QString & dirName, bool acceptAbsPath = TRUE ) [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().

       See also cdUp(), isReadable(), exists(), and path().

       Example: fileiconview/mainwindow.cpp.

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.

       See also cd(), isReadable(), exists(), and path().

QString QDir::cleanDirPath ( const QString & filePath ) [static]
       Removes all multiple directory separators "/" and resolves any"

       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".

       See also absPath() and canonicalPath().

QString QDir::convertSeparators ( const QString & pathName ) [static]
       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.

       See also isRelative().

uint QDir::count () const
       Returns the total number of directories and files that were found.

       Equivalent to entryList().count().

       See also operator[]() and entryList().

QDir QDir::current () [static]
       Returns the application's current directory.

       Use path() to access a QDir object's path.

       See also currentDirPath() and QDir::QDir().

QString QDir::currentDirPath () [static]
       Returns the absolute path of the application's current directory.

       See also current().

       Examples:

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.

       See also path(), absPath(), absFilePath(), exists(), and QString::isNull().

const QFileInfoList * QDir::drives () [static]
       Returns a list of the root directories on this system. On Windows this returns a number of
       QFileInfo objects containing "C:/", "D:/" etc. On other operating systems, it returns a
       list containing just one root directory (e.g. "/").

       The returned pointer is owned by Qt. Callers should not delete or modify it.

       Example: dirview/main.cpp.

QStrList QDir::encodedEntryList ( int filterSpec = DefaultFilter, int sortSpec = DefaultSort )
       const [virtual]
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       This function is included to easy porting from Qt 1.x to Qt 2.0, it is the same as
       entryList(), but encodes the filenames as 8-bit strings using QFile::encodedName().

       It is more efficient to use entryList().

QStrList QDir::encodedEntryList ( const QString & nameFilter, int filterSpec = DefaultFilter, int
       sortSpec = DefaultSort ) const [virtual]
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

const QFileInfoList * QDir::entryInfoList ( const QString & nameFilter, int filterSpec =
       DefaultFilter, int sortSpec = DefaultSort ) const [virtual]
       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 nameFilter, 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.

       See also entryList(), setNameFilter(), setSorting(), and setFilter().

QStringList QDir::entryList ( const QString & nameFilter, int filterSpec = DefaultFilter, int
       sortSpec = DefaultSort ) const [virtual]
       Returns a list of the names of 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 nameFilter, filterSpec
       and sortSpec arguments.

       Returns an empty list if the directory is unreadable or does not exist.

       See also entryInfoList(), setNameFilter(), setSorting(), and setFilter().

       arguments.

       Returns an empty list if the directory is unreadable or does not exist.

       See also entryInfoList(), setNameFilter(), setSorting(), and setFilter().

bool QDir::exists ( const QString & name, bool acceptAbsPath = TRUE ) [virtual]
       Checks for the existence of the file name.

       If acceptAbsPath is TRUE a path starting with separator "/" will check the file with the
       absolute path. If acceptAbsPath is FALSE any number of separators at the beginning of name
       will be removed and the resultant file name will be checked.

       Returns TRUE if the file exists; otherwise returns FALSE.

       See also QFileInfo::exists() and QFile::exists().

bool QDir::exists () const [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Returns TRUE if the directory exists; otherwise returns FALSE. (If a file with the same
       name is found this function will return FALSE).

       See also QFileInfo::exists() and QFile::exists().

QString QDir::filePath ( const QString & fileName, bool acceptAbsPath = TRUE ) const [virtual]
       Returns the path name of a file in the directory. Does not check if the file actually
       exists in the directory. If the QDir is relative the returned path name will also be
       relative. 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.

       See also absFilePath(), isRelative(), and canonicalPath().

FilterSpec QDir::filter () const
       Returns the value set by setFilter()

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:&#92;" is used.

       Under non-Windows operating systems the HOME environment variable is used if it exists,
       otherwise rootDirPath() is used.

       See also homeDirPath().

QString QDir::homeDirPath () [static]
       Returns the absolute path of the user's home directory.

bool QDir::isReadable () const [virtual]
       Returns TRUE if the directory is readable and we can open files by name; otherwise returns
       FALSE.

       Warning: A FALSE value from this function is not a guarantee that files in the directory
       are not accessible.

       See also QFileInfo::isReadable().

       Examples:

bool QDir::isRelative () const [virtual]
       Returns TRUE if the directory path is relative to the current directory and returns FALSE
       if the path is absolute (e.g. under UNIX a path is relative if it does not start with a
       "/").

       See also convertToAbs().

bool QDir::isRelativePath ( const QString & path ) [static]
       Returns TRUE if path is relative; returns FALSE if it is absolute.

       See also isRelative().

bool QDir::isRoot () const [virtual]
       Returns TRUE if the directory is the root directory; otherwise returns FALSE.

       Note: If the directory is a symbolic link to the root directory this function returns
       FALSE. If you want to test for this use canonicalPath(), e.g.

	   QDir d( "/tmp/root_link" );
	   d = d.canonicalPath();
	   if ( d.isRoot() )
	       qWarning( "It is a root link!" );

       See also root() and rootDirPath().

bool QDir::match ( const QString & filter, const QString & fileName ) [static]
       Returns TRUE if the fileName matches the wildcard (glob) pattern filter; otherwise returns
       FALSE. The filter may contain multiple patterns separated by spaces or semicolons.

       (See QRegExp wildcard matching.)

       See also QRegExp::match().

bool QDir::match ( const QStringList & filters, const QString & fileName ) [static]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Returns TRUE if the fileName matches any of the wildcard (glob) patterns in the list of
       filters; otherwise returns FALSE.

       (See QRegExp wildcard matching.)

       See also QRegExp::match().

bool QDir::matchAllDirs () const
       Returns the value set by setMatchAllDirs()

       See also setMatchAllDirs().

bool QDir::mkdir ( const QString & dirName, bool acceptAbsPath = TRUE ) const [virtual]
       Creates a directory.

       If acceptAbsPath is TRUE a path starting with a separator ('/') will create the absolute
       directory; if acceptAbsPath is FALSE any number of separators at the beginning of dirName
       will be removed.

       Returns TRUE if successful; otherwise returns FALSE.

       See also rmdir().

QString QDir::nameFilter () const
       Returns the string set by setNameFilter()

bool QDir::operator!= ( const QDir & d ) const [virtual]
       Returns TRUE if directory d and this directory have different paths or different sort or
       filter settings; otherwise returns FALSE.

       Example:

	   // The current directory is "/usr/local"
	   QDir d1( "/usr/local/bin" );
	   QDir d2( "bin" );
	   if ( d1 != d2 ) qDebug( "They differ\n" ); // This is printed

QDir &; QDir::operator= ( const QDir & d )
       Makes a copy of QDir d and assigns it to this QDir.

QDir &; QDir::operator= ( const QString & path )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Sets the directory path to be the given path.

bool QDir::operator== ( const QDir & d ) const [virtual]
       Returns TRUE if directory d and this directory have the same path and their sort and
       filter settings are the same; otherwise returns FALSE.

       Example:

	   // The current directory is "/usr/local"
	   QDir d1( "/usr/local/bin" );
	   QDir d2( "bin" );
	   d2.convertToAbs();
	   if ( d1 == d2 ) qDebug( "They're the same\n" ); // This is printed

QString QDir::operator[] ( int index ) const
       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.

       See also count() and entryList().

QString QDir::path () const [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()).

       See also setPath(), absPath(), exists(), cleanDirPath(), dirName(), absFilePath(), and
       convertSeparators().

void QDir::refresh () const
       Refreshes the directory information.

bool QDir::remove ( const QString & fileName, bool acceptAbsPath = TRUE ) [virtual]
       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.

bool QDir::rename ( const QString & oldName, const QString & newName, bool acceptAbsPaths = TRUE
       ) [virtual]
       Renames a file or directory.

       If acceptAbsPaths is TRUE a path starting with a separator ('/') will rename the file with
       the absolute path; if acceptAbsPaths is FALSE any number of separators at the beginning of
       the names will be removed.

       Returns TRUE if successful; otherwise returns FALSE.

       On most file systems, rename() fails only if oldName does not exist or if newName and
       oldName are not on the same partition. On Windows, rename() will fail if newName already
       exists. However, there are also other reasons why rename() can fail. For example, on at
       least one file system rename() fails if newName points to an open file.

       Example: fileiconview/qfileiconview.cpp.

bool QDir::rmdir ( const QString & dirName, bool acceptAbsPath = TRUE ) const [virtual]
       Removes a directory.

       If acceptAbsPath is TRUE a path starting with a separator ('/') will remove the absolute
       directory; if acceptAbsPath is FALSE any number of separators at the beginning of dirName
       will be removed.

       The directory must be empty for rmdir() to succeed.

       Returns TRUE if successful; otherwise returns FALSE.

       See also mkdir().

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

       See also rootDirPath() and drives().

QString QDir::rootDirPath () [static]
       Returns the absolute path for the root directory.

       For UNIX operating systems this returns "/". For Windows file systems this normally
       returns "c:/".

       See also root() and drives().

char QDir::separator () [static]
       Returns the native directory separator; "/" under UNIX (including Mac OS X) and "&#92;"
       under Windows.

       You do not need to use this function to build file paths. If you always use "/", Qt will
       translate your paths to conform to the underlying operating system.

bool QDir::setCurrent ( const QString & path ) [static]
       Sets the application's current working directory to path. Returns TRUE if the directory
       was successfully changed; otherwise returns FALSE.

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.

       See also filter() and setNameFilter().

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.

       See also matchAllDirs().

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").

       See also nameFilter() and setFilter().

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".

       See also path(), absPath(), exists(), cleanDirPath(), dirName(), absFilePath(),
       isRelative(), and convertToAbs().

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.

       See also sorting() and SortSpec.

SortSpec QDir::sorting () const
       Returns the value set by setSorting()

       See also setSorting() and SortSpec.
