<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>This class provides functions that reads text data using an input stream, allowing you to read text, floats, and integers. </p>
<p>The <a class="el" href="classwx_text_input_stream.html" title="This class provides functions that reads text data using an input stream, allowing you to read text...">wxTextInputStream</a> correctly reads text files (or streams) in DOS, Macintosh and Unix formats and reports a single newline char as a line ending.</p>
<p>wxTextInputStream::operator>>() is overloaded and you can use this class like a standard C++ iostream. Note, however, that the arguments are the fixed size types wxUint32, wxInt32 etc and on a typical 32-bit computer, none of these match to the "long" type (wxInt32 is defined as int on 32-bit architectures) so that you cannot use long. To avoid problems (here and elsewhere), make use of wxInt32, wxUint32 and similar types.</p>
<p>If you're scanning through a file using <a class="el" href="classwx_text_input_stream.html" title="This class provides functions that reads text data using an input stream, allowing you to read text...">wxTextInputStream</a>, you should check for <code>EOF</code> <b>before</b> reading the next item (word / number), because otherwise the last item may get lost. You should however be prepared to receive an empty item (empty string / zero number) at the end of file, especially on Windows systems. This is unavoidable because most (but not all) files end with whitespace (i.e. usually a newline).</p>
<p>For example:</p>
<div class="fragment"><div class="line"><a class="code" href="classwx_file_input_stream.html" title="This class represents data read in from a file.">wxFileInputStream</a> input( <span class="stringliteral">"mytext.txt"</span> );</div>
<div class="line"><a class="code" href="classwx_text_input_stream.html" title="This class provides functions that reads text data using an input stream, allowing you to read text...">wxTextInputStream</a> text( input );</div>
<div class="line"><a class="code" href="defs_8h.html#aad88e290b822df511ad8025ee2e45263" title="8 bit type (the mapping is more complex than a simple typedef and is not shown here).">wxUint8</a> i1;</div>
<div class="line"><span class="keywordtype">float</span> f2;</div>
<div class="line"><a class="code" href="classwx_string.html" title="String class for passing textual data to or receiving it from wxWidgets.">wxString</a> line;</div>
<div class="line"></div>
<div class="line">text >> i1; <span class="comment">// read a 8 bit integer.</span></div>
