  \class QTreeWidgetItemIterator
  \ingroup model-view
  \brief The QTreeWidgetItemIterator class provides a way to iterate over the
  items in a QTreeWidget instance.

  The iterator will walk the items in a pre-order traversal order, thus visiting the
  parent node \e before it continues to the child nodes.

  For example, the following code examples each item in a tree, checking the
  text in the first column against a user-specified search string:

  \snippet doc/src/snippets/qtreewidgetitemiterator-using/mainwindow.cpp 0

  It is also possible to filter out certain types of node by passing certain
  \l{IteratorFlag}{flags} to the constructor of QTreeWidgetItemIterator.

  \sa QTreeWidget, {Model/View Programming}, QTreeWidgetItem
*/

/*!
    Constructs an iterator for the same QTreeWidget as \a it. The
    current iterator item is set to point on the current item of \a it.
