</PRE>
<P>
<p>The <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a> class provides an interface for reading from and writing to files.</p>
<p><a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a> is an I/O device for reading and writing text and binary files and <a href="%2E%2E/resources.html">resources</tt></a>. A <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a> may be used by itself or, more conveniently, with a <a href="QTextStream.html"><tt>QTextStream</tt></a> or <a href="QDataStream.html"><tt>QDataStream</tt></a>.</p>
<p>The file name is usually passed in the constructor, but it can be set at any time using <a href="QFile.html#setFileName(java.lang.String)"><tt>setFileName</tt></a>. You can check for a file's existence using <a href="QFile.html#exists(java.lang.String)"><tt>exists</tt></a>, and remove a file using <a href="QFile.html#remove(java.lang.String)"><tt>remove</tt></a>. (More advanced file system related operations are provided by <a href="QFileInfo.html"><tt>QFileInfo</tt></a> and <a href="QDir.html"><tt>QDir</tt></a>.)</p>
<p>The file is opened with <a href="QFile.html#open(com.trolltech.qt.core.QIODevice.OpenMode)"><tt>open</tt></a>, closed with <a href="QFile.html#close()"><tt>close</tt></a>, and flushed with <a href="QFile.html#flush()"><tt>flush</tt></a>. Data is usually read and written using <a href="QDataStream.html"><tt>QDataStream</tt></a> or <a href="QTextStream.html"><tt>QTextStream</tt></a>, but you can also call the <a href="QIODevice.html#QIODevice(com.trolltech.qt.core.QObject)"><tt>QIODevice</tt></a>-inherited functions <a href="QIODevice.html#read(long)"><tt>read</tt></a>, <a href="QIODevice.html#readLine(long)"><tt>readLine</tt></a>, <a href="QIODevice.html#readAll()"><tt>readAll</tt></a>, <a href="QIODevice.html#write(com.trolltech.qt.core.QByteArray)"><tt>write</tt></a>. <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a> also inherits getChar(), putChar(), and ungetChar(), which work one character at a time.</p>
<p>The size of the file is returned by <a href="QFile.html#size()"><tt>size</tt></a>. You can get the current file position using <a href="QFile.html#pos()"><tt>pos</tt></a>, or move to a new file position using <a href="QFile.html#seek(long)"><tt>seek</tt></a>. If you've reached the end of the file, <a href="QFile.html#atEnd()"><tt>atEnd</tt></a> returns true.</p>
<a name="reading-files-directly"></a>
<h3>Reading Files Directly</h3>
<p>The following example reads a text file line by line:</p>
<pre> QFile file("in.txt");
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
return;
while (!file.atEnd()) {
QByteArray line = file.readLine();
process_line(line);
}</pre>
<p>The QIODevice::Text flag passed to <a href="QFile.html#open(com.trolltech.qt.core.QIODevice.OpenMode)"><tt>open</tt></a> tells Qt to convert Windows-style line terminators ("\r\n") into C++-style terminators ("\n"). By default, <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a> assumes binary, i.e. it doesn't perform any conversion on the bytes stored in the file.</p>
<a name="using-streams-to-read-files"></a>
<h3>Using Streams to Read Files</h3>
<p>The next example uses <a href="QTextStream.html"><tt>QTextStream</tt></a> to read a text file line by line:</p>
<pre> QFile file("in.txt");
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
return;
QTextStream in(&file);
while (!in.atEnd()) {
QString line = in.readLine();
process_line(line);
}</pre>
<p><a href="QTextStream.html"><tt>QTextStream</tt></a> takes care of converting the 8-bit data stored on disk into a 16-bit Unicode <a href="%2E%2E/porting4.html#qstring"><tt>QString</tt></a>. By default, it assumes that the user system's local 8-bit encoding is used (e.g., ISO 8859-1 for most of Europe; see QTextCodec::codecForLocale() for details). This can be changed using setCodec().</p>
<p>To write text, we can use operator<<(), which is overloaded to take a <a href="QTextStream.html"><tt>QTextStream</tt></a> on the left and various data types (including <a href="%2E%2E/porting4.html#qstring"><tt>QString</tt></a>) on the right:</p>
<pre> QFile file("out.txt");
if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
return;
QTextStream out(&file);
out << "The magic number is: " << 49 << "\n";</pre>
<p><a href="QDataStream.html"><tt>QDataStream</tt></a> is similar, in that you can use operator<<() to write data and operator>>() to read it back. See the class documentation for details.</p>
<p>When you use <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a>, <a href="QFileInfo.html"><tt>QFileInfo</tt></a>, and <a href="QDir.html"><tt>QDir</tt></a> 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 use standard C++ APIs (<tt><cstdio></tt> or <tt><iostream></tt>) or platform-specific APIs to access files instead of <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a>, you can use the <a href="QFile.html#encodeName(java.lang.String)"><tt>encodeName</tt></a> and <a href="QFile.html#decodeName(com.trolltech.qt.core.QByteArray)"><tt>decodeName</tt></a> functions to convert between Unicode file names and 8-bit file names.</p>
<p>On Unix, there are some special system files (e.g. in <tt>/proc</tt>) for which <a href="QFile.html#size()"><tt>size</tt></a> will always return 0, yet you may still be able to read more data from such a file; the data is generated in direct response to you calling <a href="QIODevice.html#read(long)"><tt>read</tt></a>. In this case, however, you cannot use <a href="QFile.html#atEnd()"><tt>atEnd</tt></a> to determine if there is more data to read (since <a href="QFile.html#atEnd()"><tt>atEnd</tt></a> will return true for a file that claims to have size 0). Instead, you should either call <a href="QIODevice.html#readAll()"><tt>readAll</tt></a>, or call <a href="QIODevice.html#read(long)"><tt>read</tt></a> or <a href="QIODevice.html#readLine(long)"><tt>readLine</tt></a> repeatedly until no more data can be read. The next example uses <a href="QTextStream.html"><tt>QTextStream</tt></a> to read <tt>/proc/modules</tt> line by line:</p>
<pre> QFile file("/proc/modules");
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
return;
QTextStream in(&file);
QString line = in.readLine();
while (!line.isNull()) {
process_line(line);
line = in.readLine();
}</pre>
<a name="signals"></a>
<h3>Signals</h3>
<p>Unlike other <a href="QIODevice.html#QIODevice(com.trolltech.qt.core.QObject)"><tt>QIODevice</tt></a> implementations, such as <a href="%2E%2E/network/QTcpSocket.html"><tt>QTcpSocket</tt></a>, <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a> does not emit the <a href="QFile.html#aboutToClose()"><tt>aboutToClose</tt></a>, <a href="QFile.html#bytesWritten(long)"><tt>bytesWritten</tt></a>, or <a href="QFile.html#readyRead()"><tt>readyRead</tt></a> signals. This implementation detail means that <a href="QFile.html#QFile(com.trolltech.qt.core.QObject)"><tt>QFile</tt></a> is not suitable for reading and writing certain types of files, such as device files on Unix platforms.</p>
