<hr><a name="details"></a><h2>Detailed Description</h2>
The TQValueListConstIterator class provides a const iterator
for <a href="ntqvaluelist.html">TQValueList</a>.
<p>
<p> In contrast to <a href="qvaluelistiterator.html">TQValueListIterator</a>, this class is used to iterate
over a const list. 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. It behaves essentially like the above function.
<p> Constructs a copy of the iterator <em>it</em>.
<h3 class=fn><a name="TQValueListConstIterator-4"></a>TQValueListConstIterator::TQValueListConstIterator ( const <a href="qvaluelistiterator.html">TQValueListIterator</a><T> & it )
</h3>
<p> Constructs a copy of the iterator <em>it</em>.
<h3 class=fn>bool <a name="operator!-eq"></a>TQValueListConstIterator::operator!= ( const <a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & it ) const
</h3>
<p> Compares this iterator with <em>it</em> and returns TRUE if they point
to different items; otherwise returns FALSE.
<h3 class=fn>const T & <a name="operator*"></a>TQValueListConstIterator::operator* () const
</h3>
<p> Asterisk operator. Returns a reference to the current iterator item.
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & <a name="operator++"></a>TQValueListConstIterator::operator++ ()
</h3>
<p> Prefix ++ makes the succeeding item current and returns an
iterator pointing to the new current item. The iterator cannot
check whether it reached the end of the list. Incrementing the
iterator returned by end() causes undefined results.
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> <a name="operator++-2"></a>TQValueListConstIterator::operator++ ( int )
</h3>
<p> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Postfix ++ makes the succeeding item current and returns an
iterator pointing to the new current item. The iterator cannot
check whether it reached the end of the list. Incrementing the
iterator returned by end() causes undefined results.
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & <a name="operator--"></a>TQValueListConstIterator::operator-- ()
</h3>
<p> Prefix -- makes the previous item current and returns an iterator
pointing to the new current item. The iterator cannot check
whether it reached the beginning of the list. Decrementing the
iterator returned by begin() causes undefined results.
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> <a name="operator---2"></a>TQValueListConstIterator::operator-- ( int )
</h3>
<p> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Postfix -- makes the previous item current and returns an iterator
pointing to the new current item. The iterator cannot check
whether it reached the beginning of the list. Decrementing the
iterator returned by begin() causes undefined results.
<h3 class=fn>bool <a name="operator-eq-eq"></a>TQValueListConstIterator::operator== ( const <a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & it ) const
</h3>
<p> Compares this iterator with <em>it</em> and returns TRUE if they point
to the same item; otherwise returns FALSE.
