<h2>Detailed Description</h2>
<p>The Q3TextStream class provides basic functions for reading and writing text using a <a href="qiodevice.html">QIODevice</a>.</p>
<p>The text stream class has a functional interface that is very similar to that of the standard C++ iostream class.</p>
<p>Qt provides several global functions similar to the ones in iostream:</p>

<p><b>Warning:</b> By default Q3TextStream will automatically detect whether integers in the stream are in decimal, octal, hexadecimal or binary format when reading from the stream. In particular, a leading '0' signifies octal, i.e. the sequence "0100" will be interpreted as 64.</p>
<p>The Q3TextStream class reads and writes text; it is not appropriate for dealing with binary data (but <a href="qdatastream.html">QDataStream</a> is).</p>
<p>By default, output of Unicode text (i.e. <a href="qstring.html">QString</a>) is done using the local 8-bit encoding. This can be changed using the <a href="q3textstream.html#setEncoding">setEncoding</a>() method. For input, the Q3TextStream will auto-detect standard Unicode "byte order marked" text files; otherwise the local 8-bit encoding is used.</p>
<p>The <a href="qiodevice.html">QIODevice</a> is set in the constructor, or later using <a href="q3textstream.html#setDevice">setDevice</a>(). If the end of the input is reached <a href="q3textstream.html#atEnd">atEnd</a>() returns TRUE. Data can be read into variables of the appropriate type using the operator>>() overloads, or read in its entirety into a single string using <a href="q3textstream.html#read">read</a>(), or read a line at a time using <a href="q3textstream.html#readLine">readLine</a>(). Whitespace can be skipped over using <a href="q3textstream.html#skipWhiteSpace">skipWhiteSpace</a>(). You can set flags for the stream using <a href="q3textstream.html#flags">flags</a>() or <a href="q3textstream.html#setf">setf</a>(). The stream also supports <a href="q3textstream.html#width">width</a>(), <a href="q3textstream.html#precision">precision</a>() and <a href="q3textstream.html#fill">fill</a>(); use <a href="q3textstream.html#reset">reset</a>() to reset the defaults.</p>

<p>Constructs a text stream that operates on the Unicode <a href="qstring.html">QString</a>, <i>str</i>, through an internal device. The <i>filemode</i> argument is passed to the device's open() function; see <a href="qiodevice-qt3.html#mode" class="compat">QIODevice::mode</a>().</p>
