+  \since 4.4
+  \class QScriptClassPropertyIterator
+
+  \brief The QScriptClassPropertyIterator class provides an iterator interface for custom Qt Script objects.
+
+  \ingroup script
+
+  This class is only relevant if you have subclassed QScriptClass and
+  want to provide enumeration of your custom properties (e.g. when
+  objects of your class are used with QScriptValueIterator, or with
+  the for-in statement in scripts).
+
+  The object() function returns the Qt Script object the iterator is
+  traversing.
+
+  toFront(), hasNext() and next() provide forward iteration.
+
+  toBack(), hasPrevious() and previous() provide backward iteration.
+
+  name(), id() and flags() return information about the last property
+  that was jumped over using next() or previous().
+
+  \sa QScriptClass::newIterator(), QScriptValueIterator
