Detailed Description

The QFile class is an I/O device that operates on files.

QFile is an I/O device for reading and writing binary and text files. A QFile may be used by itself or more conveniently with a QDataStream or QTextStream.

The file name is usually passed in the constructor but can be changed with setName(). You can check for a file's existence with exists() and remove a file with remove().

The file is opened with open(), closed with close() and flushed with flush(). Data is usually read and written using QDataStream or QTextStream, but you can read with readBlock() and readLine() and write with writeBlock(). QFile also supports getch(), ungetch() and putch().

The size of the file is returned by size(). You can get the current file position or move to a new file position using the at() functions. If you've reached the end of the file, atEnd() returns TRUE. The file handle is returned by handle().

Here is a code fragment that uses QTextStream to read a text file line by line. It prints each line with a line number.

    QStringList lines;
    QFile file( "file.txt" );
    if ( file.open( IO_ReadOnly ) ) {
        QTextStream stream( &file );
        QString line;
        int i = 1;
        while ( !stream.atEnd() ) {
            line = stream.readLine(); // line of text excluding '\n'
            printf( "%3d: %s\n", i++, line.latin1() );
            lines += line;
        }
        file.close();
    }

Writing text is just as easy. The following example shows how to write the data we read into the string list from the previous example:

    QFile file( "file.txt" );
    if ( file.open( IO_WriteOnly ) ) {
        QTextStream stream( &file );
        for ( QStringList::Iterator it = lines.begin(); it != lines.end(); ++it )
            stream << *it << "\n";
        file.close();
    }

The QFileInfo class holds detailed information about a file, such as access permissions, file dates and file types.

The QDir class manages directories and lists of file names.

Qt uses Unicode file names. If you want to do your own I/O on Unix systems you may want to use encodeName() (and decodeName()) to convert the file name into the local encoding.

Member Function Documentation

bool QFile::at (  Offset  pos  )  [virtual]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Sets the file index to pos. Returns TRUE if successful; otherwise returns FALSE. Example: QFile f( "data.bin" ); f.open( IO_ReadOnly ); // index set to 0 f.at( 100 ); // set index to 100 f.at( f.at()+50 ); // set index to 150 f.at( f.size()-80 ); // set index to 80 before EOF f.close(); Use at() without arguments to retrieve the file offset. Warning: The result is undefined if the file was open()'ed using the IO_Append specifier. See also: size(), open() Reimplemented from QIODevice. Definition at line 478 of file qfile_unix.cpp. References FALSE, fd, fh, QIODevice::ioIndex, QIODevice::isOpen(), QIODevice::isRaw(), QIODevice::isSequentialAccess(), l, and qWarning().

QIODevice::Offset QFile::at (   )  const [inline, virtual]

bool QFile::atEnd (   )  const [virtual]

Returns TRUE if the end of file has been reached; otherwise returns FALSE. If QFile has not been open()'d, then the behavior is undefined. See also: size() Reimplemented from QIODevice. Definition at line 298 of file qfile.cpp. References at(), QIODevice::atEnd(), FALSE, QIODevice::isDirectAccess(), QIODevice::isOpen(), QIODevice::isTranslated(), length, and qWarning().

void QFile::close (  void   )  [virtual]

Closes an open file. The file is not closed if it was opened with an existing file handle. If the existing file handle is a FILE*, the file is flushed. If the existing file handle is an int file descriptor, nothing is done to the file. Some "write-behind" filesystems may report an unspecified error on closing the file. These errors only indicate that something may have gone wrong since the previous open(). In such a case status() reports IO_UnspecifiedError after close(), otherwise IO_Ok. See also: open(), flush() Implements QIODevice. Reimplemented in MemFile.

QString QFile::decodeName (  const QCString &  localFileName  )  [static]

This does the reverse of QFile::encodeName() using localFileName. See also: setDecodingFunction() Definition at line 591 of file qfile.cpp. References decoder. Referenced by QDir::canonicalPath(), QDir::currentDirPath(), CardMonitor::getStatusSd(), QFileInfo::group(), QDir::homeDirPath(), QFileInfo::owner(), QDir::readDirEntries(), and QFileInfo::readLink().

QCString QFile::encodeName (  const QString &  fileName  )  [static]

When you use QFile, QFileInfo, and QDir to access the file system with Qt, you can use Unicode file names. On Unix, these file names are converted to an 8-bit encoding. If you want to do your own file I/O on Unix, you should convert the file name using this function. On Windows NT/2000, Unicode file names are supported directly in the file system and this function should be avoided. On Windows 95, non-Latin1 locales are not supported. By default, this function converts fileName to the local 8-bit encoding determined by the user's locale. This is sufficient for file names that the user chooses. File names hard-coded into the application should only use 7-bit ASCII filename characters. The conversion scheme can be changed using setEncodingFunction(). This might be useful if you wish to give the user an option to store file names in UTF-8, etc., but be aware that such file names would probably then be unrecognizable when seen by other programs.

void QFile::flush (   )  [virtual]

Flushes the file buffer to the disk. close() also flushes the file buffer. Implements QIODevice. Definition at line 281 of file qfile.cpp. References fh, and QIODevice::isOpen(). Referenced by QMyDialog::SaveClicked(), DCCTransferRecv::slotProcess(), and QCopEnvelope::~QCopEnvelope().

int QFile::getch (   )  [virtual]

Reads a single byte/character from the file. Returns the byte/character read, or -1 if the end of the file has been reached. See also: putch(), ungetch() Implements QIODevice. Definition at line 401 of file qfile.cpp. References buf, fh, IO_ReadError, QIODevice::ioIndex, QCString::isEmpty(), QIODevice::isOpen(), QIODevice::isRaw(), QIODevice::isReadable(), QIODevice::isSequentialAccess(), len, QCString::length(), qWarning(), readBlock(), QIODevice::setStatus(), QCString::truncate(), and ungetchBuffer. Referenced by open(), Config::read(), and Opie::MM::ExifData::ReadJpegSections().

int QFile::handle (   )  const

Returns the file handle of the file. This is a small positive integer, suitable for use with C library functions such as fdopen() and fcntl(). On systems that use file descriptors for sockets (ie. Unix systems, but not Windows) the handle can be used with QSocketNotifier as well. If the file is not open or there is an error, handle() returns -1.

void QFile::init (   )  [private]

For internal use only. Initialize internal data. Definition at line 171 of file qfile.cpp. References ext_f, FALSE, fd, fh, IO_Direct, IO_Ok, QIODevice::ioIndex, length, QIODevice::setFlags(), and QIODevice::setStatus(). Referenced by close(), open(), and QFile().

QString QFile::name (  void   )  const [inline]

Returns the name set by setName(). See also: setName(), QFileInfo::fileName() Definition at line 117 of file qfile.h. References fn. Referenced by PackageHandler::addPackageFiles(), ConfigDialog::ConfigDialog(), GPRSRun::detectState(), DCCTransfer::filename(), DspMakefileGenerator::init(), ProjectGenerator::init(), MakefileGenerator::init(), VcprojGenerator::initOld(), loadFile(), main(), SystemFile::open(), VcprojGenerator::openOutput(), DspMakefileGenerator::openOutput(), ProjectGenerator::openOutput(), MakefileGenerator::openOutput(), MetrowerksMakefileGenerator::openOutput(), ServerPI::process(), QFileInfo::QFileInfo(), TimerReceiverObject::resetTimer(), Appearance::saveSchemeClicked(), SzTransfer::sendFile(), FileTransfer::sendFile(), QFileInfo::setFile(), QSettings::sync(), WavFile::trackName(), MetrowerksMakefileGenerator::writeMakeParts(), and UnixMakefileGenerator::writeSubdirs().

bool QFile::open (  int  m, int  f )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Opens a file in the mode m using an existing file descriptor f. Returns TRUE if successful, otherwise FALSE. When a QFile is opened using this function, close() does not actually close the file. The QFile that is opened using this function, is automatically set to be in raw mode; this means that the file input/output functions are slow. If you run into performance issues, you should try to use one of the other open functions. Warning: If f is one of 0 (stdin), 1 (stdout) or 2 (stderr), you may not be able to seek. size() is set to INT_MAX (in limits.h). See also: close() Definition at line 391 of file qfile_unix.cpp. References ext_f, FALSE, fd, getch(), init(), IO_Open, IO_Raw, IO_Sequential, QIODevice::ioIndex, QIODevice::isOpen(), QIODevice::isReadable(), length, qWarning(), QIODevice::resetStatus(), QIODevice::setMode(), QIODevice::setState(), QIODevice::setType(), TRUE, and ungetch().

bool QFile::open (  int  m, FILE *  f )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Opens a file in the mode m using an existing file handle f. Returns TRUE if successful, otherwise FALSE. Example: #include <stdio.h> void printError( const char* msg ) { QFile f; f.open( IO_WriteOnly, stderr ); f.writeBlock( msg, qstrlen(msg) ); // write to stderr f.close(); } When a QFile is opened using this function, close() does not actually close the file, only flushes it. Warning: If f is stdin, stdout, stderr, you may not be able to seek. See QIODevice::isSequentialAccess() for more information. See also: close() Definition at line 329 of file qfile_unix.cpp. References ext_f, FALSE, fh, QIODevice::flags(), getch(), init(), IO_Open, IO_Raw, IO_Sequential, IO_Truncate, QIODevice::ioIndex, QIODevice::isOpen(), QIODevice::isReadable(), length, qWarning(), QIODevice::setMode(), QIODevice::setState(), QIODevice::setType(), TRUE, and ungetch().

bool QFile::open (  int  m  )  [virtual]

Opens the file specified by the file name currently set, using the mode m. Returns TRUE if successful, otherwise FALSE. IO_Raw IO_ReadOnly IO_WriteOnly IO_ReadWrite IO_Append IO_Truncate IO_Translate The mode parameter m must be a combination of the following flags: Flag Meaning IO_Raw Raw (non-buffered) file access. IO_ReadOnly Opens the file in read-only mode. IO_WriteOnly Opens the file in write-only mode. If this flag is used with another flag, e.g. IO_ReadOnly or IO_Raw or IO_Append, the file is not truncated; but if used on its own (or with IO_Truncate), the file is truncated. IO_ReadWrite Opens the file in read/write mode, equivalent to (IO_ReadOnly | IO_WriteOnly). IO_Append Opens the file in append mode. (You must actually use (IO_WriteOnly | IO_Append) to make the file writable and to go into append mode.) This mode is very useful when you want to write something to a log file. The file index is set to the end of the file. Note that the result is undefined if you position the file index manually using at() in append mode. IO_Truncate Truncates the file. IO_Translate Enables carriage returns and linefeed translation for text files under Windows. The raw access mode is best when I/O is block-operated using a 4KB block size or greater. Buffered access works better when reading small portions of data at a time. Warning: When working with buffered files, data may not be written to the file at once. Call flush() to make sure that the data is really written. If you have a buffered file opened for both reading and writing you must not perform an input operation immediately after an output operation or vice versa. You should always call flush() or a file positioning operation, e.g. at(), between input and output operations, otherwise the buffer may contain garbage. If the file does not exist and IO_WriteOnly or IO_ReadWrite is specified, it is created. Example: QFile f1( "/tmp/data.bin" ); f1.open( IO_Raw | IO_ReadWrite ); QFile f2( "readme.txt" ); f2.open( IO_ReadOnly | IO_Translate ); QFile f3( "audit.log" ); f3.open( IO_WriteOnly | IO_Append ); See also: name(), close(), isOpen(), flush() Implements QIODevice.

QFile& QFile::operator= (  const QFile &   )  [private]

int QFile::putch (  int  ch  )  [virtual]

Writes the character ch to the file. Returns ch, or -1 if some error occurred. See also: getch(), ungetch() Implements QIODevice. Definition at line 444 of file qfile.cpp. References buf, fh, IO_WriteError, QIODevice::ioIndex, QIODevice::isOpen(), QIODevice::isRaw(), QIODevice::isSequentialAccess(), QIODevice::isWritable(), length, qWarning(), QIODevice::setStatus(), and writeBlock(). Referenced by IrdaApplet::setIrdaDiscoveryStatus().

Q_LONG QFile::readBlock (  char *  p, Q_ULONG  len )  [virtual]

Warning: We have experienced problems with some C libraries when a buffered file is opened for both reading and writing. If a read operation takes place immediately after a write operation, the read buffer contains garbage data. Worse, the same garbage is written to the file. Calling flush() before readBlock() solved this problem. Implements QIODevice.

Q_LONG QFile::readLine (  QString &  s, Q_ULONG  maxlen )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Reads a line of text. Reads bytes from the file into string s, until end-of-line or maxlen bytes have been read, whichever occurs first. Returns the number of bytes read, or -1 if there was an error, e.g. end of file. Any terminating newline is not stripped. This function is only efficient for buffered files. Avoid using readLine() for files that have been opened with the IO_Raw flag. Note that the string is read as plain Latin1 bytes, not Unicode. See also: readBlock(), QTextStream::readLine() Definition at line 380 of file qfile.cpp. References l, and readLine().

Q_LONG QFile::readLine (  char *  p, Q_ULONG  maxlen )  [virtual]

Reads a line of text. Reads bytes from the file into the char* p, until end-of-line or maxlen bytes have been read, whichever occurs first. Returns the number of bytes read, or -1 if there was an error. Any terminating newline is not stripped. This function is only efficient for buffered files. Avoid readLine() for files that have been opened with the IO_Raw flag. See also: readBlock(), QTextStream::readLine() Reimplemented from QIODevice.

bool QFile::remove (  const QString &  fileName  )  [static]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Removes the file fileName. Returns TRUE if successful, otherwise FALSE. Definition at line 70 of file qfile_unix.cpp. References encodeName(), FALSE, QString::isEmpty(), and qWarning().

bool QFile::remove (   )

Removes the file specified by the file name currently set. Returns TRUE if successful; otherwise returns FALSE. The file is closed before it is removed.

void QFile::setDecodingFunction (  DecoderFn  f  )  [static]

Sets the function for decoding 8-bit file names to f. The default uses the locale-specific 8-bit encoding. See also: encodeName(), decodeName() Definition at line 611 of file qfile.cpp. References decoder.

void QFile::setEncodingFunction (  EncoderFn  f  )  [static]

Sets the function for encoding Unicode file names to f. The default encodes in the locale-specific 8-bit encoding. See also: encodeName() Definition at line 573 of file qfile.cpp. References encoder.

void QFile::setName (  const QString &  name  )

Sets the name of the file to name. The name can have no path, a relative path or an absolute absolute path. Do not call this function if the file has already been opened. If the file name has no path or a relative path, the path used will be whatever the application's current directory path is {at the time of the open()} call. Example: QFile file; QDir::setCurrent( "/tmp" ); file.setName( "readme.txt" ); QDir::setCurrent( "/home" ); file.open( IO_ReadOnly ); // opens "/home/readme.txt" under Unix Note that the directory separator "/" works for all operating systems supported by Qt.

int QFile::ungetch (  int  ch  )  [virtual]

Puts the character ch back into the file and decrements the index if it is not zero. This function is normally called to "undo" a getch() operation. Returns ch, or -1 if an error occurred. See also: getch(), putch() Implements QIODevice. Definition at line 484 of file qfile.cpp. References at(), buf, fh, IO_ReadError, QIODevice::ioIndex, QIODevice::isOpen(), QIODevice::isRaw(), QIODevice::isReadable(), QIODevice::isSequentialAccess(), qWarning(), QIODevice::setStatus(), ungetchBuffer, and writeBlock().

Q_LONG QFile::writeBlock (  const QByteArray &  data  )  [inline]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Reimplemented from QIODevice. Definition at line 86 of file qfile.h. References QIODevice::writeBlock().

Q_LONG QFile::writeBlock (  const char *  p, Q_ULONG  len )  [virtual]

Writes len bytes from p to the file and returns the number of bytes actually written. Returns -1 if a serious error occurred. Warning: When working with buffered files, data may not be written to the file at once. Call flush() to make sure the data is really written. See also: readBlock() Implements QIODevice.
