       The QPtrDictIterator class provides an iterator for QPtrDict collections.

       QPtrDictIterator is implemented as a template class. Define a template instance
       QPtrDictIterator<X> to create a dictionary iterator that operates on QPtrDict<X>
       (dictionary of X*).


	   QPtrDict<char> fields;
	   QLineEdit *le1 = new QLineEdit( this );
	   le1->setText( "Simpson" );
	   QLineEdit *le2 = new QLineEdit( this );
	   le2->setText( "Homer" );
	   QLineEdit *le3 = new QLineEdit( this );
	   le3->setText( "45" );
	   fields.insert( le1, "Surname" );
	   fields.insert( le2, "Forename" );
	   fields.insert( le3, "Age" );
	   QPtrDictIterator<char> it( fields );
	   for( ; it.current(); ++it ) {
	       QLineEdit *le = (QLineEdit)it.currentKey();
	       cout << it.current() << ": " << le->text() << endl;
	   cout << endl;
	   // Output (random order):
	   //  Forename: Homer
	   //  Age: 45
	   //  Surname: Simpson
       In the example we insert some line edits into a dictionary, associating a string with
       each. We then iterate over the dictionary printing the associated strings.

       Multiple iterators may independently traverse the same dictionary. A QPtrDict knows about
       all the iterators that are operating on the dictionary. When an item is removed from the
       dictionary, QPtrDict updates all iterators that refer the removed item to point to the
       next item in the traversing order.

       See also QPtrDict, Collection Classes, and Non-GUI Classes.

QPtrDictIterator::QPtrDictIterator ( const QPtrDict<type> & dict )
       Constructs an iterator for dict. The current iterator item is set to point on the first
       item in the dict.

QPtrDictIterator::~QPtrDictIterator ()
       Destroys the iterator.

uint QPtrDictIterator::count () const
       Returns the number of items in the dictionary this iterator operates on.

       See also isEmpty().

type * QPtrDictIterator::current () const
       Returns a pointer to the current iterator item's value.

void * QPtrDictIterator::currentKey () const
       Returns the current iterator item's key.

bool QPtrDictIterator::isEmpty () const
       Returns TRUE if the dictionary is empty; otherwise returns FALSE.

       See also count().

QPtrDictIterator::operator type * () const
       Cast operator. Returns a pointer to the current iterator item. Same as current().

type * QPtrDictIterator::operator() ()
       Makes the succeeding item current and returns the original current item.

       If the current iterator item was the last item in the dictionary or if it was 0, 0 is

type * QPtrDictIterator::operator++ ()
       Prefix ++ makes the succeeding item current and returns the new current item.

       If the current iterator item was the last item in the dictionary or if it was 0, 0 is

type * QPtrDictIterator::operator+= ( uint jump )
       Sets the current item to the item jump positions after the current item and returns a
       pointer to that item.

       If that item is beyond the last item or if the dictionary is empty, it sets the current
       item to 0 and returns 0.

type * QPtrDictIterator::toFirst ()
       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
