<h2>Detailed Description</h2>
<p>The iterator class provides an iterator for reading the contents of a <a href="qtextframe.html">QTextFrame</a>.</p>
<p>A frame consists of an arbitrary sequence of <a href="qtextblock.html">QTextBlock</a>s and child <a href="qtextframe.html">QTextFrame</a>s. This class provides a way to iterate over the child objects of a frame, and read their contents. It does not provide a way to modify the contents of the frame.</p>
<hr />
<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="iterator"></a>iterator::iterator ()</h3>
<p>Constructs an invalid iterator.</p>
<h3 class="fn"><a name="iterator-3"></a>iterator::iterator ( const iterator & <i>other</i> )</h3>
<p>Copy constructor. Constructs a copy of the <i>other</i> iterator.</p>
<h3 class="fn"><a name="atEnd"></a>bool iterator::atEnd () const</h3>
<p>Returns true if the current item is the last item in the text frame.</p>
<h3 class="fn"><a name="currentBlock"></a><a href="qtextblock.html">QTextBlock</a> iterator::currentBlock () const</h3>
<p>Returns the current block the iterator points to. If the iterator points to a child frame, the returned block is invalid.</p>
<p>See also <a href="qtextframe-iterator.html#currentFrame">currentFrame</a>().</p>
<h3 class="fn"><a name="currentFrame"></a><a href="qtextframe.html">QTextFrame</a> * iterator::currentFrame () const</h3>
<p>Returns the current frame pointed to by the iterator, or 0 if the iterator currently points to a block.</p>
<p>See also <a href="qtextframe-iterator.html#currentBlock">currentBlock</a>().</p>
<h3 class="fn"><a name="parentFrame"></a><a href="qtextframe.html">QTextFrame</a> * iterator::parentFrame () const</h3>
<p>Returns the parent frame of the current frame.</p>
<p>See also <a href="qtextframe-iterator.html#currentFrame">currentFrame</a>() and <a href="qtextframe.html#parentFrame">QTextFrame::parentFrame</a>().</p>
<h3 class="fn"><a name="operator-not-eq"></a>bool iterator::operator!= ( const iterator & <i>other</i> ) const</h3>
<p>Retuns true if the iterator is different from the <i>other</i> iterator; otherwise returns false.</p>
<h3 class="fn"><a name="operator-2b-2b"></a>iterator & iterator::operator++ ()</h3>
<p>Moves the iterator to the next frame or block.</p>
<p>See also <a href="qtextframe-iterator.html#currentBlock">currentBlock</a>() and <a href="qtextframe-iterator.html#currentFrame">currentFrame</a>().</p>
<h3 class="fn"><a name="operator-2b-2b-2"></a>iterator iterator::operator++ ( int )</h3>
<p>This is an overloaded member function, provided for convenience.</p>
<p>The postfix ++ operator (<tt>i++</tt>) advances the iterator to the next item in the text frame, and returns an iterator to the old item.</p>
<h3 class="fn"><a name="operator--"></a>iterator & iterator::operator-- ()</h3>
<p>Moves the iterator to the previous frame or block.</p>
<p>See also <a href="qtextframe-iterator.html#currentBlock">currentBlock</a>() and <a href="qtextframe-iterator.html#currentFrame">currentFrame</a>().</p>
<h3 class="fn"><a name="operator---2"></a>iterator iterator::operator-- ( int )</h3>
<p>This is an overloaded member function, provided for convenience.</p>
<p>The postfix -- operator (<tt>i--</tt>) makes the preceding item in the current frame, and returns an iterator to the old item.</p>
<h3 class="fn"><a name="operator-eq"></a>iterator & iterator::operator= ( const iterator & <i>other</i> )</h3>
<p>Assigns <i>other</i> to this iterator and returns a reference to this iterator.</p>
<h3 class="fn"><a name="operator-eq-eq"></a>bool iterator::operator== ( const iterator & <i>other</i> ) const</h3>
<p>Retuns true if the iterator is the same as the <i>other</i> iterator; otherwise returns false.</p>
