<p>This class is only relevant if you have subclassed <a href="qscriptclass.html">QScriptClass</a> and want to provide enumeration of your custom properties (e.g. when objects of your class are used with <a href="qscriptvalueiterator.html">QScriptValueIterator</a>, or with the for-in statement in scripts).</p>
<p>The <a href="qscriptclasspropertyiterator.html#object">object</a>() function returns the Qt Script object the iterator is traversing.</p>
<p><a href="qscriptclasspropertyiterator.html#toFront">toFront</a>(), <a href="qscriptclasspropertyiterator.html#hasNext">hasNext</a>() and <a href="qscriptclasspropertyiterator.html#next">next</a>() provide forward iteration.</p>
<p><a href="qscriptclasspropertyiterator.html#toBack">toBack</a>(), <a href="qscriptclasspropertyiterator.html#hasPrevious">hasPrevious</a>() and <a href="qscriptclasspropertyiterator.html#previous">previous</a>() provide backward iteration.</p>
<p><a href="qscriptclasspropertyiterator.html#name">name</a>(), <a href="qscriptclasspropertyiterator.html#id">id</a>() and <a href="qscriptclasspropertyiterator.html#flags">flags</a>() return information about the last property that was jumped over using <a href="qscriptclasspropertyiterator.html#next">next</a>() or <a href="qscriptclasspropertyiterator.html#previous">previous</a>().</p>
<p>See also <a href="qscriptclass.html#newIterator">QScriptClass.newIterator</a>() and <a href="qscriptvalueiterator.html">QScriptValueIterator</a>.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QScriptClassPropertyIterator" />QScriptClassPropertyIterator.__init__ (<i>self</i>, <a href="qscriptvalue.html">QScriptValue</a>)</h3><p>Constructs an iterator for traversing <i>object</i>.</p>
<p>Subclasses should ensure that the iterator is set to the front of the sequence of properties (before the first property).</p>
<a name="//apple_ref/cpp/instm/QScriptClassPropertyIterator/~QScriptClassPropertyIterator" />
<h3 class="fn"><a name="flags" /><a href="qscriptvalue-propertyflags.html">QScriptValue.PropertyFlags</a> QScriptClassPropertyIterator.flags (<i>self</i>)</h3><p>Returns the flags of the last property that was jumped over using <a href="qscriptclasspropertyiterator.html#next">next</a>() or <a href="qscriptclasspropertyiterator.html#previous">previous</a>().</p>
<p>The default implementation calls the propertyFlags() function of <a href="qscriptclasspropertyiterator.html#object">object</a>() with argument <a href="qscriptclasspropertyiterator.html#name">name</a>().</p>

<a name="//apple_ref/cpp/instm/QScriptClassPropertyIterator/id" />
<h3 class="fn"><a name="id" />int QScriptClassPropertyIterator.id (<i>self</i>)</h3><p>Returns the id of the last property that was jumped over using <a href="qscriptclasspropertyiterator.html#next">next</a>() or <a href="qscriptclasspropertyiterator.html#previous">previous</a>().</p>
<p>The default implementation returns 0.</p>
