The TQDir class provides access to directory structures and their contents in a platform-independent way.
< p >
< p > A TQDir is used to manipulate path names, access information
regarding paths and files, and manipulate the underlying file
system.
< p > A TQDir 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, TQt 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.
< p > The "current" path refers to the application's working directory.
A TQDir's own path is set and retrieved with < a href = "#setPath" > setPath< / a > () and < a href = "#path" > path< / a > ().
< p > An example of an absolute path is the string "/tmp/quartz", a
relative path might look like "src/fatlib". You can use the
function < a href = "#isRelative" > isRelative< / a > () to check if a TQDir is using a relative or an
absolute file path. Call < a href = "#convertToAbs" > convertToAbs< / a > () to convert a relative TQDir
to an absolute one. For a simplified path use < a href = "#cleanDirPath" > cleanDirPath< / a > (). To
obtain a path which has no symbolic links or redundant ".."
elements use < a href = "#canonicalPath" > canonicalPath< / a > (). The path can be set with setPath(),
and changed with < a href = "#cd" > cd< / a > () and < a href = "#cdUp" > cdUp< / a > ().
< p > TQDir provides several static functions, for example, < a href = "#setCurrent" > setCurrent< / a > ()
to set the application's working directory and < a href = "#currentDirPath" > currentDirPath< / a > () to
retrieve the application's working directory. Access to some
common paths is provided with the static functions, < a href = "#current" > current< / a > (),
< a href = "#home" > home< / a > () and < a href = "#root" > root< / a > () which return TQDir objects or currentDirPath(),
< a href = "#homeDirPath" > homeDirPath< / a > () and < a href = "#rootDirPath" > rootDirPath< / a > () which return the path as a string.
If you want to know about your application's path use
< a href = "ntqapplication.html#applicationDirPath" > TQApplication::applicationDirPath< / a > ().
< p > The number of entries in a directory is returned by < a href = "#count" > count< / a > ().
Obtain a string list of the names of all the files and directories
in a directory with < a href = "#entryList" > entryList< / a > (). If you prefer a list of < a href = "ntqfileinfo.html" > TQFileInfo< / a >
pointers use < a href = "#entryInfoList" > entryInfoList< / a > (). 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 < a href = "#setNameFilter" > setNameFilter< / a > (), < a href = "#setFilter" > setFilter< / a > () and < a href = "#setSorting" > setSorting< / a > ().
They may also be specified in the entryList() and
entryInfoList()'s arguments.
< p > Create a new directory with < a href = "#mkdir" > mkdir< / a > (), rename a directory with
< a href = "#rename" > rename< / a > () and remove an existing directory with < a href = "#rmdir" > rmdir< / a > (). Remove a
file with < a href = "#remove" > remove< / a > (). You can interrogate a directory with < a href = "#exists" > exists< / a > (),
< a href = "#isReadable" > isReadable< / a > () and < a href = "#isRoot" > isRoot< / a > ().
< p > To get a path with a filename use < a href = "#filePath" > filePath< / a > (), and to get a
directory name use < a href = "#dirName" > dirName< / a > (); neither of these functions checks
for the existence of the file or directory.
< p > The list of root directories is provided by < a href = "#drives" > drives< / a > (); on Unix
systems this returns a list containing one root directory, "/"; on
Windows the list will usually contain "C:/", and possibly "D:/",
etc.
< p > It is easiest to work with "/" separators in TQt 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
< a href = "#convertSeparators" > convertSeparators< / a > ().
< p > Examples:
< p > See if a directory exists.
< pre >
TQDir d( "example" ); // "./example"
if ( !d.< a href = "#exists" > exists< / a > () )
< a href = "ntqapplication.html#qWarning" > tqWarning< / a > ( "Cannot find the example directory" );
< / pre >
< p > Traversing directories and reading a file.
< pre >
TQDir d = TQDir::< a href = "#root" > root< / a > (); // "/"
if ( !d.< a href = "#cd" > cd< / a > ("tmp") ) { // "/tmp"
< a href = "ntqapplication.html#qWarning" > tqWarning< / a > ( "Cannot find the \"/tmp\" directory" );
} else {
< a href = "ntqfile.html" > TQFile< / a > f( d.< a href = "#filePath" > filePath< / a > ("ex1.txt") ); // "/tmp/ex1.txt"
if ( !f.< a href = "ntqfile.html#open" > open< / a > (IO_ReadWrite) )
< a href = "ntqapplication.html#qWarning" > tqWarning< / a > ( "Cannot create the file %s", f.< a href = "ntqfile.html#name" > name< / a > () );
}
< / pre >
< p > A program that lists all the files in the current directory
(excluding symbolic links), sorted by size, smallest first:
< pre >
#include < stdio.h>
#include < < a href = "qdir-h.html" > ntqdir.h< / a > >

< h3 class = fn > < a name = "FilterSpec-enum" > < / a > TQDir::FilterSpec< / h3 >
< p > This enum describes the filtering options available to TQDir, e.g.
for < a href = "#entryList" > entryList< / a > () and < a href = "#entryInfoList" > entryInfoList< / a > (). The filter value is specified
by OR-ing together values from the following list:
< ul >
< li > < tt > TQDir::Dirs< / tt > - List directories only.
< li > < tt > TQDir::Files< / tt > - List files only.
< li > < tt > TQDir::Drives< / tt > - List disk drives (ignored under Unix).
< li > < tt > TQDir::NoSymLinks< / tt > - Do not list symbolic links (ignored by operating
systems that don't support symbolic links).
< li > < tt > TQDir::All< / tt > - List directories, files, drives and symlinks (this does not list
broken symlinks unless you specify System).
< li > < tt > TQDir::TypeMask< / tt > - A mask for the the Dirs, Files, Drives and
NoSymLinks flags.
< li > < tt > TQDir::Readable< / tt > - List files for which the application has read access.
< li > < tt > TQDir::Writable< / tt > - List files for which the application has write access.
< li > < tt > TQDir::Executable< / tt > - List files for which the application has execute
access. Executables needs to be combined with Dirs or Files.
< li > < tt > TQDir::RWEMask< / tt > - A mask for the Readable, Writable and Executable flags.
< li > < tt > TQDir::Modified< / tt > - Only list files that have been modified (ignored
under Unix).
< li > < tt > TQDir::Hidden< / tt > - List hidden files (on Unix, files starting with a .).
< li > < tt > TQDir::System< / tt > - List system files (on Unix, FIFOs, sockets and
device files)
< li > < tt > TQDir::AccessMask< / tt > - A mask for the Readable, Writable, Executable
Modified, Hidden and System flags
< li > < tt > TQDir::DefaultFilter< / tt > - Internal flag.

default easy to write and at the same time useful.
< p > Examples: < tt > Readable|Writable< / tt > means list all files for which the
application has read access, write access or both. < tt > Dirs|Drives< / tt >
means list drives, directories, all files that the application can
read, write or execute, and also symlinks to such
files/directories.
< h3 class = fn > < a name = "SortSpec-enum" > < / a > TQDir::SortSpec< / h3 >

< li > < tt > TQDir::Size< / tt > - Sort by file size.
< li > < tt > TQDir::Unsorted< / tt > - Do not sort.
< li > < tt > TQDir::SortByMask< / tt > - A mask for Name, Time and Size.

< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > < a name = "TQDir" > < / a > TQDir::TQDir ()
< / h3 >
Constructs a TQDir pointing to the current directory (".").
< p > < p > See also < a href = "#currentDirPath" > currentDirPath< / a > ().
< h3 class = fn > < a name = "TQDir-2" > < / a > TQDir::TQDir ( const < a href = "ntqstring.html" > TQString< / a > & path, const < a href = "ntqstring.html" > TQString< / a > & nameFilter = TQString::null, int sortSpec = Name | IgnoreCase, int filterSpec = All )
< / h3 >
Constructs a TQDir with path < em > path< / em > , that filters its entries by
name using < em > nameFilter< / em > and by attributes using < em > filterSpec< / em > . It
also sorts the names using < em > sortSpec< / em > .
< p > The default < em > nameFilter< / em > is an empty string, which excludes
nothing; the default < em > filterSpec< / em > is < a href = "#FilterSpec-enum" > All< / a > , which also means
exclude nothing. The default < em > sortSpec< / em > is < tt > Name|IgnoreCase< / tt > ,
i.e. sort by name case-insensitively.
< p > Example that lists all the files in "/tmp":
< pre >
TQDir d( "/tmp" );
for ( int i = 0; i < d.< a href = "#count" > count< / a > (); i++ )
printf( "%s\n", d[i] );
< / pre >
< p > If < em > path< / em > is "" or < a href = "ntqstring.html#TQString-null" > TQString::null< / a > , TQDir uses "." (the current
directory). If < em > nameFilter< / em > is "" or TQString::null, TQDir uses the
name filter "*" (all files).
< p > Note that < em > path< / em > need not exist.
< p > < p > See also < a href = "#exists" > exists< / a > (), < a href = "#setPath" > setPath< / a > (), < a href = "#setNameFilter" > setNameFilter< / a > (), < a href = "#setFilter" > setFilter< / a > (), and < a href = "#setSorting" > setSorting< / a > ().

< / h3 >
Returns the absolute path name of a file in the directory. Does < em > not< / em > check if the file actually exists in the directory. Redundant
multiple separators or "." and ".." directories in < em > fileName< / em >
will not be removed (see < a href = "#cleanDirPath" > cleanDirPath< / a > ()).
< p > If < em > acceptAbsPath< / em > is TRUE a < em > fileName< / em > starting with a

< / h3 >
Returns the canonical path, i.e. a path without symbolic links or
redundant "." or ".." elements.
< p > On systems that do not have symbolic links this function will
always return the same string that < a href = "#absPath" > absPath< / a > () returns. If the
canonical path does not exist (normally due to dangling symbolic
links) < a href = "#canonicalPath" > canonicalPath< / a > () returns < a href = "ntqstring.html#TQString-null" > TQString::null< / a > .

< / h3 >
Changes the TQDir's directory to < em > dirName< / em > .
< p > If < em > acceptAbsPath< / em > is TRUE a path starting with separator "/"
will cause the function to change to the absolute directory. If < em > acceptAbsPath< / em > is FALSE any number of separators at the beginning
of < em > dirName< / em > will be removed and the function will descend into
< em > dirName< / em > .
< p > Returns TRUE if the new directory exists and is readable;
otherwise returns FALSE. Note that the logical < a href = "#cd" > cd< / a > () operation is
not performed if the new directory does not exist.

< / h3 >
Removes all multiple directory separators "/" and resolves any
"."s or ".."s found in the path, < em > filePath< / em > .
< p > 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".

separators that are appropriate for the underlying operating
system.
< p > On Windows, < a href = "#convertSeparators" > convertSeparators< / a > ("c:/winnt/system32") returns

< p > < p > See also < a href = "#count" > count< / a > () and < a href = "#entryList" > entryList< / a > ().
< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "path" > < / a > TQDir::path () const< tt > [virtual]< / tt >
< / h3 >
< p > Returns the path, this may contain symbolic links, but never
contains redundant ".", ".." or multiple separators.
< p > The returned path can be either absolute or relative (see
< a href = "#setPath" > setPath< / a > ()).
< p > < p > See also < a href = "#setPath" > setPath< / a > (), < a href = "#absPath" > absPath< / a > (), < a href = "#exists" > exists< / a > (), < a href = "#cleanDirPath" > cleanDirPath< / a > (), < a href = "#dirName" > dirName< / a > (), < a href = "#absFilePath" > absFilePath< / a > (), and < a href = "#convertSeparators" > convertSeparators< / a > ().
< h3 class = fn > void < a name = "refresh" > < / a > TQDir::refresh () const
< / h3 >
Refreshes the directory information.
< h3 class = fn > bool < a name = "remove" > < / a > TQDir::remove ( const < a href = "ntqstring.html" > TQString< / a > & fileName, bool acceptAbsPath = TRUE )< tt > [virtual]< / tt >
< / h3 >
Removes the file, < em > fileName< / em > .
< p > If < em > acceptAbsPath< / em > is TRUE a path starting with separator "/"
will remove the file with the absolute path. If < em > acceptAbsPath< / em >
is FALSE any number of separators at the beginning of < em > fileName< / em >
will be removed and the resultant file name will be removed.
< p > Returns TRUE if the file is removed successfully; otherwise
returns FALSE.
< h3 class = fn > bool < a name = "rename" > < / a > TQDir::rename ( const < a href = "ntqstring.html" > TQString< / a > & oldName, const < a href = "ntqstring.html" > TQString< / a > & newName, bool acceptAbsPaths = TRUE )< tt > [virtual]< / tt >
< / h3 >
Renames a file or directory.
< p > If < em > acceptAbsPaths< / em > is TRUE a path starting with a separator
('/') will rename the file with the absolute path; if < em > acceptAbsPaths< / em > is FALSE any number of separators at the beginning
of the names will be removed.
< p > Returns TRUE if successful; otherwise returns FALSE.
< p > On most file systems, < a href = "#rename" > rename< / a > () fails only if < em > oldName< / em > does not
exist or if < em > newName< / em > and < em > oldName< / em > are not on the same
partition. On Windows, rename() will fail if < em > newName< / em > already
exists. However, there are also other reasons why rename() can
fail. For example, on at least one file system rename() fails if
< em > newName< / em > points to an open file.
< p > Example: < a href = "fileiconview-example.html#x814" > fileiconview/qfileiconview.cpp< / a > .
< h3 class = fn > bool < a name = "rmdir" > < / a > TQDir::rmdir ( const < a href = "ntqstring.html" > TQString< / a > & dirName, bool acceptAbsPath = TRUE ) const< tt > [virtual]< / tt >
< / h3 >
Removes a directory.
< p > If < em > acceptAbsPath< / em > is TRUE a path starting with a separator ('/')
will remove the absolute directory; if < em > acceptAbsPath< / em > is FALSE
any number of separators at the beginning of < em > dirName< / em > will be
removed.
< p > The directory must be empty for < a href = "#rmdir" > rmdir< / a > () to succeed.
< p > Returns TRUE if successful; otherwise returns FALSE.
< p > < p > See also < a href = "#mkdir" > mkdir< / a > ().
< h3 class = fn > < a href = "ntqdir.html" > TQDir< / a > < a name = "root" > < / a > TQDir::root ()< tt > [static]< / tt >
< / h3 >
Returns the root directory.
< p > < p > See also < a href = "#rootDirPath" > rootDirPath< / a > () and < a href = "#drives" > drives< / a > ().
< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "rootDirPath" > < / a > TQDir::rootDirPath ()< tt > [static]< / tt >
< / h3 >
Returns the absolute path for the root directory.
< p > For UNIX operating systems this returns "/". For Windows file
systems this normally returns "c:/".
< p > < p > See also < a href = "#root" > root< / a > () and < a href = "#drives" > drives< / a > ().
< h3 class = fn > char < a name = "separator" > < / a > TQDir::separator ()< tt > [static]< / tt >
< / h3 >
Returns the native directory separator; "/" under UNIX (including
Mac OS X) and "\ " under Windows.
< p > You do not need to use this function to build file paths. If you
always use "/", TQt will translate your paths to conform to the
underlying operating system.
< h3 class = fn > bool < a name = "setCurrent" > < / a > TQDir::setCurrent ( const < a href = "ntqstring.html" > TQString< / a > & path )< tt > [static]< / tt >
< / h3 >
Sets the application's current working directory to < em > path< / em > .
Returns TRUE if the directory was successfully changed; otherwise
returns FALSE.
< h3 class = fn > void < a name = "setFilter" > < / a > TQDir::setFilter ( int filterSpec )< tt > [virtual]< / tt >
< / h3 >
Sets the filter used by < a href = "#entryList" > entryList< / a > () and < a href = "#entryInfoList" > entryInfoList< / a > () to < em > filterSpec< / em > . The filter is used to specify the kind of files that
should be returned by entryList() and entryInfoList(). See
< a href = "#FilterSpec-enum" > TQDir::FilterSpec< / a > .
< p > < p > See also < a href = "#filter" > filter< / a > () and < a href = "#setNameFilter" > setNameFilter< / a > ().
< h3 class = fn > void < a name = "setMatchAllDirs" > < / a > TQDir::setMatchAllDirs ( bool enable )< tt > [virtual]< / tt >
< / h3 >
If < em > enable< / em > is TRUE then all directories are included (e.g. in
< a href = "#entryList" > entryList< / a > ()), and the < a href = "#nameFilter" > nameFilter< / a > () is only applied to the files.
If < em > enable< / em > is FALSE then the nameFilter() is applied to both
directories and files.
< p > < p > See also < a href = "#matchAllDirs" > matchAllDirs< / a > ().
< h3 class = fn > void < a name = "setNameFilter" > < / a > TQDir::setNameFilter ( const < a href = "ntqstring.html" > TQString< / a > & nameFilter )< tt > [virtual]< / tt >
< / h3 >
Sets the name filter used by < a href = "#entryList" > entryList< / a > () and < a href = "#entryInfoList" > entryInfoList< / a > () to < em > nameFilter< / em > .
< p > The < em > nameFilter< / em > is a wildcard (globbing) filter that understands
"*" and "?" wildcards. (See < a href = "ntqregexp.html#wildcard-matching" > TQRegExp wildcard matching< / a > .) You may specify several filter
entries all separated by a single space " " or by a semi-colon
";".
< p > For example, if you want entryList() and entryInfoList() to list
all files ending with either ".cpp" or ".h", you would use either
dir.< a href = "#setNameFilter" > setNameFilter< / a > ("*.cpp *.h") or dir.setNameFilter("*.cpp;*.h").
< p > < p > See also < a href = "#nameFilter" > nameFilter< / a > () and < a href = "#setFilter" > setFilter< / a > ().
< h3 class = fn > void < a name = "setPath" > < / a > TQDir::setPath ( const < a href = "ntqstring.html" > TQString< / a > & path )< tt > [virtual]< / tt >
< / h3 >
Sets the path of the directory to < em > path< / em > . The path is cleaned of
redundant ".", ".." and of multiple separators. No check is made
to ensure that a directory with this path exists.
< p > 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".
< p > < p > See also < a href = "#path" > path< / a > (), < a href = "#absPath" > absPath< / a > (), < a href = "#exists" > exists< / a > (), < a href = "#cleanDirPath" > cleanDirPath< / a > (), < a href = "#dirName" > dirName< / a > (), < a href = "#absFilePath" > absFilePath< / a > (), < a href = "#isRelative" > isRelative< / a > (), and < a href = "#convertToAbs" > convertToAbs< / a > ().
< h3 class = fn > void < a name = "setSorting" > < / a > TQDir::setSorting ( int sortSpec )< tt > [virtual]< / tt >
< / h3 >
Sets the sort order used by < a href = "#entryList" > entryList< / a > () and < a href = "#entryInfoList" > entryInfoList< / a > ().
< p > The < em > sortSpec< / em > is specified by OR-ing values from the enum
< a href = "#SortSpec-enum" > TQDir::SortSpec< / a > .
< p > < p > See also < a href = "#sorting" > sorting< / a > () and < a href = "#SortSpec-enum" > SortSpec< / a > .
< h3 class = fn > < a href = "ntqdir.html#SortSpec-enum" > SortSpec< / a > < a name = "sorting" > < / a > TQDir::sorting () const
< / h3 >
< p > Returns the value set by < a href = "#setSorting" > setSorting< / a > ()
< p > < p > See also < a href = "#setSorting" > setSorting< / a > () and < a href = "#SortSpec-enum" > SortSpec< / a > .
