103 //************* QFile -

104 -

105 /*! -

106 \class QFile -

107 \inmodule QtCore -

108 \brief The QFile class provides an interface for reading from and writing to files. -

109 -

110 \ingroup io -

111 -

112 \reentrant -

113 -

114 QFile is an I/O device for reading and writing text and binary -

115 files and \l{The Qt Resource System}{resources}. A QFile may be -

116 used by itself or, more conveniently, with a QTextStream or -

117 QDataStream. -

118 -

119 The file name is usually passed in the constructor, but it can be -

120 set at any time using setFileName(). QFile expects the file -

121 separator to be '/' regardless of operating system. The use of -

122 other separators (e.g., '\\') is not supported. -

123 -

124 You can check for a file's existence using exists(), and remove a -

125 file using remove(). (More advanced file system related operations -

126 are provided by QFileInfo and QDir.) -

127 -

128 The file is opened with open(), closed with close(), and flushed -

129 with flush(). Data is usually read and written using QDataStream -

130 or QTextStream, but you can also call the QIODevice-inherited -

131 functions read(), readLine(), readAll(), write(). QFile also -

132 inherits getChar(), putChar(), and ungetChar(), which work one -

133 character at a time. -

134 -

135 The size of the file is returned by size(). You can get the -

136 current file position using pos(), or move to a new file position -

137 using seek(). If you've reached the end of the file, atEnd() -

138 returns \c true. -

139 -

140 \section1 Reading Files Directly -

141 -

142 The following example reads a text file line by line: -

143 -

144 \snippet file/file.cpp 0 -

145 -

146 The QIODevice::Text flag passed to open() tells Qt to convert -

147 Windows-style line terminators ("\\r\\n") into C++-style -

148 terminators ("\\n"). By default, QFile assumes binary, i.e. it -

149 doesn't perform any conversion on the bytes stored in the file. -

150 -

151 \section1 Using Streams to Read Files -

152 -

153 The next example uses QTextStream to read a text file -

154 line by line: -

155 -

156 \snippet file/file.cpp 1 -

157 -

158 QTextStream takes care of converting the 8-bit data stored on -

159 disk into a 16-bit Unicode QString. By default, it assumes that -

160 the user system's local 8-bit encoding is used (e.g., UTF-8 -

161 on most unix based operating systems; see QTextCodec::codecForLocale() for -

162 details). This can be changed using \l QTextStream::setCodec(). -

163 -

164 To write text, we can use operator<<(), which is overloaded to -

165 take a QTextStream on the left and various data types (including -

166 QString) on the right: -

167 -

168 \snippet file/file.cpp 2 -

169 -

170 QDataStream is similar, in that you can use operator<<() to write -

171 data and operator>>() to read it back. See the class -

172 documentation for details. -

173 -

174 When you use QFile, QFileInfo, and QDir to access the file system -

175 with Qt, you can use Unicode file names. On Unix, these file -

176 names are converted to an 8-bit encoding. If you want to use -

177 standard C++ APIs (\c <cstdio> or \c <iostream>) or -

178 platform-specific APIs to access files instead of QFile, you can -

179 use the encodeName() and decodeName() functions to convert -

180 between Unicode file names and 8-bit file names. -

181 -

182 On Unix, there are some special system files (e.g. in \c /proc) for which -

183 size() will always return 0, yet you may still be able to read more data -

184 from such a file; the data is generated in direct response to you calling -

185 read(). In this case, however, you cannot use atEnd() to determine if -

186 there is more data to read (since atEnd() will return true for a file that -

187 claims to have size 0). Instead, you should either call readAll(), or call -

188 read() or readLine() repeatedly until no more data can be read. The next -

189 example uses QTextStream to read \c /proc/modules line by line: -

190 -

191 \snippet file/file.cpp 3 -

192 -

193 \section1 Signals -

194 -

195 Unlike other QIODevice implementations, such as QTcpSocket, QFile does not -

196 emit the aboutToClose(), bytesWritten(), or readyRead() signals. This -

197 implementation detail means that QFile is not suitable for reading and -

198 writing certain types of files, such as device files on Unix platforms. -

199 -

200 \section1 Platform Specific Issues -

201 -

202 File permissions are handled differently on Unix-like systems and -

203 Windows. In a non \l{QIODevice::isWritable()}{writable} -

204 directory on Unix-like systems, files cannot be created. This is not always -

205 the case on Windows, where, for instance, the 'My Documents' -

206 directory usually is not writable, but it is still possible to -

207 create files in it. -

208 -

209 Qt's understanding of file permissions is limited, which affects especially -

210 the \l QFile::setPermissions() function. On Windows, Qt will set only the -

211 legacy read-only flag, and that only when none of the Write* flags are -

212 passed. Qt does not manipulate access control lists (ACLs), which makes this -

213 function mostly useless for NTFS volumes. It may still be of use for USB -

214 sticks that use VFAT file systems. POSIX ACLs are not manipulated, either. -

215 -

897 Opens the existing file handle \a fh in the given \a mode. -

898 \a handleFlags may be used to specify additional options. -

899 Returns \c true if successful; otherwise returns \c false. -

900 -

901 Example: -

902 \snippet code/src_corelib_io_qfile.cpp 3 -

903 -

904 When a QFile is opened using this function, behaviour of close() is -

905 controlled by the AutoCloseHandle flag. -

906 If AutoCloseHandle is specified, and this function succeeds, -

907 then calling close() closes the adopted handle. -

908 Otherwise, close() does not actually close the file, but only flushes it. -

909 -

910 \b{Warning:} -

911 \list 1 -

912 \li If \a fh does not refer to a regular file, e.g., it is \c stdin, -

913 \c stdout, or \c stderr, you may not be able to seek(). size() -

914 returns \c 0 in those cases. See QIODevice::isSequential() for -

915 more information. -

916 \li Since this function opens the file without specifying the file name, -

917 you cannot use this QFile with a QFileInfo. -

918 \endlist -

919 -

920 \note For Windows CE you may not be able to call resize(). -

921 -

922 \sa close() -

923 -

924 \b{Note for the Windows Platform} -

925 -

926 \a fh must be opened in binary mode (i.e., the mode string must contain -

927 'b', as in "rb" or "wb") when accessing files and other random-access -

928 devices. Qt will translate the end-of-line characters if you pass -

929 QIODevice::Text to \a mode. Sequential devices, such as stdin and stdout, -

930 are unaffected by this limitation. -

931 -

932 You need to enable support for console applications in order to use the -

933 stdin, stdout and stderr streams at the console. To do this, add the -

934 following declaration to your application's project file: -

970 \a handleFlags may be used to specify additional options. -

971 Returns \c true if successful; otherwise returns \c false. -

972 -

973 When a QFile is opened using this function, behaviour of close() is -

974 controlled by the AutoCloseHandle flag. -

975 If AutoCloseHandle is specified, and this function succeeds, -

976 then calling close() closes the adopted handle. -

977 Otherwise, close() does not actually close the file, but only flushes it. -

978 -

979 The QFile that is opened using this function is automatically set -

980 to be in raw mode; this means that the file input/output functions -

981 are slow. If you run into performance issues, you should try to -

982 use one of the other open functions. -

983 -

984 \warning If \a fd is not a regular file, e.g, it is 0 (\c stdin), -

985 1 (\c stdout), or 2 (\c stderr), you may not be able to seek(). In -

986 those cases, size() returns \c 0. See QIODevice::isSequential() -

987 for more information. -

988 -

989 \warning For Windows CE you may not be able to call seek(), and size() -

990 returns \c 0. -

992 \warning Since this function opens the file without specifying the file name, -

993 you cannot use this QFile with a QFileInfo. -
