We then iterate over the +dictionary printing the associated strings. +<p> Multiple iterators may independently traverse the same dictionary. +A <a href="qptrdict.html">TQPtrDict</a> knows about all the iterators that are operating on the +dictionary. When an item is removed from the dictionary, TQPtrDict +updates all iterators that refer the removed item to point to the +next item in the traversing order. +<p> <p>See also <a href="qptrdict.html">TQPtrDict</a>, <a href="collection.html">Collection Classes</a>, and <a href="tools.html">Non-GUI Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQPtrDictIterator"></a>TQPtrDictIterator::TQPtrDictIterator ( const <a href="qptrdict.html">TQPtrDict</a><type> & dict ) +</h3> + +<p> Constructs an iterator for <em>dict</em>.
