<!-- $$$QTextStream-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QTextStream class provides a convenient interface for reading and writing text.</p>
<p>QTextStream can operate on a <a href="qiodevice.html">QIODevice</a>, a <a href="qbytearray.html">QByteArray</a> or a <a href="qstring.html">QString</a>. Using QTextStream's streaming operators, you can conveniently read and write words, lines and numbers. For generating text, QTextStream supports formatting options for field padding and alignment, and formatting of numbers. Example:</p>
<pre class="cpp"> <span class="type"><a href="qfile.html">QFile</a></span> data(<span class="string">"output.txt"</span>);
<span class="keyword">if</span> (data<span class="operator">.</span>open(<span class="type"><a href="qfile.html">QFile</a></span><span class="operator">::</span>WriteOnly <span class="operator">|</span> <span class="type"><a href="qfile.html">QFile</a></span><span class="operator">::</span>Truncate)) {
<span class="type">QTextStream</span> out(<span class="operator">&</span>data);
out <span class="operator"><</span><span class="operator"><</span> <span class="string">"Result: "</span> <span class="operator"><</span><span class="operator"><</span> <a href="qtextstream.html#qSetFieldWidth">qSetFieldWidth</a>(<span class="number">10</span>) <span class="operator"><</span><span class="operator"><</span> left <span class="operator"><</span><span class="operator"><</span> <span class="number">3.14</span> <span class="operator"><</span><span class="operator"><</span> <span class="number">2.7</span>;
<span class="comment">// writes "Result: 3.14 2.7 "</span>
}</pre>
<p>It's also common to use QTextStream to read console input and write console output. QTextStream is locale aware, and will automatically decode standard input using the correct codec. Example:</p>
<pre class="cpp"> <span class="type">QTextStream</span> stream(stdin);
<span class="type"><a href="qstring.html">QString</a></span> line;
<span class="keyword">do</span> {
line <span class="operator">=</span> stream<span class="operator">.</span>readLine();
} <span class="keyword">while</span> (<span class="operator">!</span>line<span class="operator">.</span>isNull());</pre>
<p>Besides using QTextStream's constructors, you can also set the device or string QTextStream operates on by calling <a href="qtextstream.html#setDevice">setDevice</a>() or <a href="qtextstream.html#setString">setString</a>(). You can seek to a position by calling <a href="qtextstream.html#seek">seek</a>(), and <a href="qtextstream.html#atEnd">atEnd</a>() will return true when there is no data left to be read. If you call <a href="qtextstream.html#flush">flush</a>(), QTextStream will empty all data from its write buffer into the device and call <a href="qtextstream.html#flush">flush</a>() on the device.</p>
<p>Internally, QTextStream uses a Unicode based buffer, and <a href="qtextcodec.html">QTextCodec</a> is used by QTextStream to automatically support different character sets. By default, <a href="qtextcodec.html#codecForLocale">QTextCodec::codecForLocale</a>() is used for reading and writing, but you can also set the codec by calling <a href="qtextstream.html#setCodec">setCodec</a>(). Automatic Unicode detection is also supported. When this feature is enabled (the default behavior), QTextStream will detect the UTF-16 or the UTF-32 BOM (Byte Order Mark) and switch to the appropriate UTF codec when reading. QTextStream does not write a BOM by default, but you can enable this by calling setGenerateByteOrderMark(true). When QTextStream operates on a <a href="qstring.html">QString</a> directly, the codec is disabled.</p>
<p>There are three general ways to use QTextStream when reading text files:</p>
<ul>
<li>Chunk by chunk, by calling <a href="qtextstream.html#readLine">readLine</a>() or <a href="qtextstream.html#readAll">readAll</a>().</li>
<li>Word by word. QTextStream supports streaming into QStrings, QByteArrays and char* buffers. Words are delimited by space, and leading white space is automatically skipped.</li>
<li>Character by character, by streaming into <a href="qchar.html">QChar</a> or char types. This method is often used for convenient input handling when parsing files, independent of character encoding and end-of-line semantics. To skip white space, call <a href="qtextstream.html#skipWhiteSpace">skipWhiteSpace</a>().</li>
</ul>
<p>Since the text stream uses a buffer, you should not read from the stream using the implementation of a superclass. For instance, if you have a <a href="qfile.html">QFile</a> and read from it directly using <a href="qiodevice.html#readLine">QFile::readLine</a>() instead of using the stream, the text stream's internal position will be out of sync with the file's position.</p>
<p>By default, when reading numbers from a stream of text, QTextStream will automatically detect the number's base representation. For example, if the number starts with "0x", it is assumed to be in hexadecimal form. If it starts with the digits 1-9, it is assumed to be in decimal form, and so on. You can set the integer base, thereby disabling the automatic detection, by calling <a href="qtextstream.html#setIntegerBase">setIntegerBase</a>(). Example:</p>
<pre class="cpp"> <span class="type">QTextStream</span> in(<span class="string">"0x50 0x20"</span>);
<span class="type">int</span> firstNumber<span class="operator">,</span> secondNumber;
in <span class="operator">></span><span class="operator">></span> firstNumber; <span class="comment">// firstNumber == 80</span>
in <span class="operator">></span><span class="operator">></span> dec <span class="operator">></span><span class="operator">></span> secondNumber; <span class="comment">// secondNumber == 0</span>
<span class="type">char</span> ch;
in <span class="operator">></span><span class="operator">></span> ch; <span class="comment">// ch == 'x'</span></pre>
<p>QTextStream supports many formatting options for generating text. You can set the field width and pad character by calling <a href="qtextstream.html#setFieldWidth">setFieldWidth</a>() and <a href="qtextstream.html#setPadChar">setPadChar</a>(). Use <a href="qtextstream.html#setFieldAlignment">setFieldAlignment</a>() to set the alignment within each field. For real numbers, call <a href="qtextstream.html#setRealNumberNotation">setRealNumberNotation</a>() and <a href="qtextstream.html#setRealNumberPrecision">setRealNumberPrecision</a>() to set the notation (<a href="qtextstream.html#RealNumberNotation-enum">SmartNotation</a>, <a href="qtextstream.html#RealNumberNotation-enum">ScientificNotation</a>, <a href="qtextstream.html#RealNumberNotation-enum">FixedNotation</a>) and precision in digits of the generated number. Some extra number formatting options are also available through <a href="qtextstream.html#setNumberFlags">setNumberFlags</a>().</p>
