+
+
+The TQAsciiDictIterator class provides an iterator for <a href="qasciidict.html">TQAsciiDict</a> collections.
+<p>
+
+<p> TQAsciiDictIterator is implemented as a template class. Define a
+template instance TQAsciiDictIterator&lt;X&gt; to create a dictionary
+iterator that operates on TQAsciiDict&lt;X&gt; (dictionary of X*).
+<p> Example:
+<pre>
+ <a href="qasciidict.html">TQAsciiDict</a>&lt;TQLineEdit&gt; fields;
+ fields.<a href="qasciidict.html#insert">insert</a>( "forename", new <a href="qlineedit.html">TQLineEdit</a>( this ) );
+ fields.<a href="qasciidict.html#insert">insert</a>( "surname", new <a href="qlineedit.html">TQLineEdit</a>( this ) );
+ fields.<a href="qasciidict.html#insert">insert</a>( "age", new <a href="qlineedit.html">TQLineEdit</a>( this ) );
+
+ fields["forename"]-&gt;setText( "Homer" );
+ fields["surname"]-&gt;setText( "Simpson" );
+ fields["age"]-&gt;setText( "45" );
+
+ TQAsciiDictIterator&lt;TQLineEdit&gt; it( fields );
+ for( ; it.<a href="#current">current</a>(); ++it )
+ cout &lt;&lt; it.<a href="#currentKey">currentKey</a>() &lt;&lt; ": " &lt;&lt; it.<a href="#current">current</a>()-&gt;text() &lt;&lt; endl;
+ cout &lt;&lt; endl;
+
+ // Output (random order):
+ // age: 45
+ // surname: Simpson
+ // forename: Homer
+ </pre>
+
+In the example we insert some line edits into a dictionary, then
+iterate over the dictionary printing the strings associated with
+those line edits.
+<p> Note that the traversal order is arbitrary; you are not guaranteed
+any particular order.
+<p> Multiple iterators may independently traverse the same dictionary.
+A <a href="qasciidict.html">TQAsciiDict</a> knows about all the iterators that are operating on
+the dictionary. When an item is removed from the dictionary,
+TQAsciiDict updates all the iterators that are referring to the
+removed item to point to the next item in the (arbitrary)
+traversal order.
+<p> <p>See also <a href="qasciidict.html">TQAsciiDict</a>, <a href="collection.html">Collection Classes</a>, and <a href="tools.html">Non-GUI Classes</a>.

+<h3 class=fn><a name="TQAsciiDictIterator"></a>TQAsciiDictIterator::TQAsciiDictIterator ( const&nbsp;<a href="qasciidict.html">TQAsciiDict</a>&lt;type&gt;&nbsp;&amp;&nbsp;dict )
+</h3>
+
+<p> Constructs an iterator for <em>dict</em>. The current iterator item is
+set to point on the first item in the <em>dict</em>.
+
+<h3 class=fn><a name="~TQAsciiDictIterator"></a>TQAsciiDictIterator::~TQAsciiDictIterator ()
+</h3>
+
+<p> Destroys the iterator.
+
+<h3 class=fn>uint <a name="count"></a>TQAsciiDictIterator::count () const
+</h3>
+
+<p> Returns the number of items in the dictionary this iterator
+operates over.
+<p> <p>See also <a href="#isEmpty">isEmpty</a>().
+
+<h3 class=fn>type * <a name="current"></a>TQAsciiDictIterator::current () const
+</h3>
+
+<p> Returns a pointer to the current iterator item.
+
+<h3 class=fn>const char * <a name="currentKey"></a>TQAsciiDictIterator::currentKey () const
+</h3>
+
+<p> Returns a pointer to the key for the current iterator item.
+
+<h3 class=fn>bool <a name="isEmpty"></a>TQAsciiDictIterator::isEmpty () const
+</h3>
+
+<p> Returns TRUE if the dictionary is empty, i.e. <a href="#count">count</a>() == 0,
+otherwise returns FALSE.
+<p> <p>See also <a href="#count">count</a>().
+
+<h3 class=fn><a name="operator-type-*"></a>TQAsciiDictIterator::operator type * () const
+</h3>
+
+<p> Cast operator. Returns a pointer to the current iterator item.
+Same as <a href="#current">current</a>().
+
+<h3 class=fn>type * <a name="operator()"></a>TQAsciiDictIterator::operator() ()
+</h3>
+
+<p> Makes the succeeding item current and returns the original current
+item.
+<p> If the current iterator item was the last item in the dictionary
+or if it was 0, 0 is returned.
+
+<h3 class=fn>type * <a name="operator++"></a>TQAsciiDictIterator::operator++ ()
+</h3>
+
+<p> Prefix ++ makes the succeeding item current and returns the new
+current item.
+<p> If the current iterator item was the last item in the dictionary
+or if it was 0, 0 is returned.
+
+<h3 class=fn>type * <a name="operator+-eq"></a>TQAsciiDictIterator::operator+= ( uint&nbsp;jump )
+</h3>
+
+<p> Sets the current item to the item <em>jump</em> positions after the
+current item, and returns a pointer to that item.
+<p> If that item is beyond the last item or if the dictionary is
+empty, it sets the current item to 0 and returns 0.
+
+<h3 class=fn>type * <a name="toFirst"></a>TQAsciiDictIterator::toFirst ()
+</h3>
+
+<p> Sets the current iterator item to point to the first item in the
+dictionary and returns a pointer to the item. If the dictionary is
+empty it sets the current item to 0 and returns 0.
