<hr><h2><a name="details"></a>Detailed Description</h2>
The abstract base class of internal layout iterators.
<p>
To be subclassed by custom layout implementors. The functions that
need to be implemented are <a href="#e03723">next</a>(), <a href="#cdab98">current</a>() and <a href="#fa72ce">takeCurrent</a>().
<p>The QGLayoutIterator implements the functionality of
<a href="qlayoutiterator.html">QLayoutIterator</a>. Each subclass of <a href="qlayout.html">QLayout</a> needs a
QGLayoutIterator subclass.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="06ad02"></a>QGLayoutIterator::~QGLayoutIterator() <code>[virtual]</code></h3>
<p>Destroys the iterator.
<h3 class="fn"><a href="qlayoutitem.html">QLayoutItem</a>*<a name="cdab98"></a>QGLayoutIterator::current() <code>[virtual]</code></h3>
<p>Implemented in subclasses to return the current item, or 0 if there
is no current item.
<h3 class="fn"><a href="qlayoutitem.html">QLayoutItem</a>*<a name="e03723"></a>QGLayoutIterator::next() <code>[virtual]</code></h3>
<p>Implemented in subclasses to move the iterator to the next item and
return that item, or 0 if there is no next item.
<h3 class="fn"><a href="qlayoutitem.html">QLayoutItem</a>*<a name="fa72ce"></a>QGLayoutIterator::takeCurrent() <code>[virtual]</code></h3>
<p>Implemented in subclasses to remove the current item from the layout
without deleting it, move the iterator to the next item and return
the removed item, or 0 if no item was removed.
