<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>
