It does not allow modification of the values of the list since that would break const semantics. <p> You can create the appropriate const iterator type by using the <tt>const_iterator</tt> typedef provided by TQValueList. <p> For more information on TQValueList iterators, see TQValueListIterator. <p> <p>See also <a href="qvaluelistiterator.html">TQValueListIterator</a>, <a href="ntqvaluelist.html">TQValueList</a>, <a href="ntqtl.html">TQt Template Library Classes</a>, and <a href="tools.html">Non-GUI Classes</a>. <hr><h2>Member Type Documentation</h2> <h3 class=fn><a name="pointer"></a>TQValueListConstIterator::pointer</h3> Pointer to value_type. <h3 class=fn><a name="reference"></a>TQValueListConstIterator::reference</h3> Reference to value_type. <h3 class=fn><a name="value_type"></a>TQValueListConstIterator::value_type</h3> The type of value. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQValueListConstIterator"></a>TQValueListConstIterator::TQValueListConstIterator () </h3> <p> Creates un uninitialized iterator. <h3 class=fn><a name="TQValueListConstIterator-3"></a>TQValueListConstIterator::TQValueListConstIterator ( const <a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & it ) </h3> <p> This is an overloaded member function, provided for convenience.
