It is then the programmer's responsibility to ensure that the Unicode data exists for the entire lifetime of the TQConstString object. <p> A TQConstString is created with the TQConstString constructor. The string held by the object can be obtained by calling <a href="#string">string</a>(). <p>See also <a href="text.html">Text Related Classes</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQConstString"></a>TQConstString::TQConstString ( const <a href="qchar.html">TQChar</a> * unicode, uint length ) </h3> Constructs a TQConstString that uses the first <em>length</em> Unicode characters in the array <em>unicode</em>. Any attempt to modify copies of the string will cause it to create a copy of the data, thus it remains forever unmodified. <p> The data in <em>unicode</em> is not copied. The caller must be able to guarantee that <em>unicode</em> will not be deleted or modified. <h3 class=fn><a name="~TQConstString"></a>TQConstString::~TQConstString () </h3> Destroys the TQConstString, creating a copy of the data if other strings are still using it. <h3 class=fn>const <a href="ntqstring.html">TQString</a> & <a name="string"></a>TQConstString::string () const </h3> <p> Returns a constant string referencing the data passed during construction. <!-- eof --> <hr><p> This file is part of the <a href="index.html">TQt toolkit</a>.
