<hr><a name="details"></a><h2>Detailed Description</h2>
The TQIntDictIterator class provides an iterator for <a href="tqintdict.html">TQIntDict</a> collections.
<p>
<p> TQIntDictIterator is implemented as a template class. Define a
template instance TQIntDictIterator<X> to create a dictionary
iterator that operates on TQIntDict<X> (dictionary of X*).
<p> Example:
<pre>
<a href="tqintdict.html">TQIntDict</a><TQLineEdit> fields;
for ( int i = 0; i < 3; i++ )
fields.<a href="tqintdict.html#insert">insert</a>( i, new <a href="tqlineedit.html">TQLineEdit</a>( this ) );
fields[0]->setText( "Homer" );
fields[1]->setText( "Simpson" );
fields[2]->setText( "45" );
TQIntDictIterator<TQLineEdit> it( fields );
for ( ; it.<a href="#current">current</a>(); ++it )
cout << it.<a href="#currentKey">currentKey</a>() << ": " << it.<a href="#current">current</a>()->text() << endl;
// Output (random order):
// 0: Homer
// 1: Simpson
// 2: 45
</pre>
<p> Note that the traversal order is arbitrary; you are not guaranteed the
order shown above.
<p> Multiple iterators may independently traverse the same dictionary.
A <a href="tqintdict.html">TQIntDict</a> knows about all the iterators that are operating on the
dictionary. When an item is removed from the dictionary, TQIntDict
updates all iterators that refer the removed item to point to the
next item in the traversal order.
<p> <p>See also <a href="tqintdict.html">TQIntDict</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="TQIntDictIterator"></a>TQIntDictIterator::TQIntDictIterator ( const <a href="tqintdict.html">TQIntDict</a><type> & dict )
</h3>
<p> Constructs an iterator for <em>dict</em>. The current iterator item is
set to point to the 'first' item in the <em>dict</em>. The first item
refers to the first item in the dictionary's arbitrary internal
ordering.
<h3 class=fn><a name="~TQIntDictIterator"></a>TQIntDictIterator::~TQIntDictIterator ()
</h3>
<p> Destroys the iterator.
<h3 class=fn>uint <a name="count"></a>TQIntDictIterator::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>TQIntDictIterator::current () const
</h3>
<p> Returns a pointer to the current iterator item.
<h3 class=fn>long <a name="currentKey"></a>TQIntDictIterator::currentKey () const
</h3>
<p> Returns the key for the current iterator item.
<h3 class=fn>bool <a name="isEmpty"></a>TQIntDictIterator::isEmpty () const
</h3>
<p> Returns TRUE if the dictionary is empty; otherwise eturns FALSE.
<p> <p>See also <a href="#count">count</a>().
<h3 class=fn><a name="operator-type-*"></a>TQIntDictIterator::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>TQIntDictIterator::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>TQIntDictIterator::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>TQIntDictIterator::operator+= ( uint 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>TQIntDictIterator::toFirst ()
</h3>
<p> Sets the current iterator item to point to the first item in the
dictionary and returns a pointer to the item. The first item
refers to the first item in the dictionary's arbitrary internal
ordering. If the dictionary is empty it sets the current item to
0 and returns 0.
