|
|
|
|
|
|
|
|
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>
|
|
|
|

|
|
(excluding symbolic links), sorted by size, smallest first:

<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.
|
|
</ul><p> If you do not set any of <a href="#FilterSpec-enum">Readable</a>, <a href="#FilterSpec-enum">Writable</a> or <a href="#FilterSpec-enum">Executable</a>, TQDir will set all three of them. This makes the
|
|
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>
|
|
|
|
<p> This enum describes the sort options available to TQDir, e.g. for
|
|
<a href="#entryList">entryList</a>() and <a href="#entryInfoList">entryInfoList</a>(). The sort value is specified by
|
|
OR-ing together values from the following list:
|
|
<ul>
|
|
<li><tt>TQDir::Name</tt> - Sort by name.
|
|
<li><tt>TQDir::Time</tt> - Sort by time (modification time).
|
|
<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.
|
|
<li><tt>TQDir::DirsFirst</tt> - Put the directories first, then the files.
|
|
<li><tt>TQDir::Reversed</tt> - Reverse the sort order.
|
|
<li><tt>TQDir::IgnoreCase</tt> - Sort case-insensitively.
|
|
<li><tt>TQDir::LocaleAware</tt> - Sort names using locale aware compares
|
|
<li><tt>TQDir::DefaultSort</tt> - Internal flag.
|
|
</ul><p> You can only specify one of the first four.
|
|
<p> If you specify both <a href="#SortSpec-enum">DirsFirst</a> and <a href="#SortSpec-enum">Reversed</a>, directories are
|
|
still put first, but in reverse order; the files will be listed
|
|
after the directories, again in reverse order.

<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.

|
|
Changes the TQDir's directory to <em>dirName</em>.
|
|
<p> If <em>acceptAbsPath</em> is TRUE a path starting with separator "/"

<em>dirName</em>.
|

<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

<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>().

<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>.
