DESCRIPTION

       The QAsciiDictIterator class provides an iterator for QAsciiDict collections.

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

       Example:

	   QAsciiDict<QLineEdit> fields;
	   fields.insert( "forename", new QLineEdit( this ) );
	   fields.insert( "surname", new QLineEdit( this ) );
	   fields.insert( "age", new QLineEdit( this ) );
	   fields["forename"]->setText( "Homer" );
	   fields["surname"]->setText( "Simpson" );
	   fields["age"]->setText( "45" );
	   QAsciiDictIterator<QLineEdit> it( fields );
	   for( ; it.current(); ++it )
	       cout << it.currentKey() << ": " << it.current()->text() << endl;
	   cout << endl;
	   // Output (random order):
	   //  age: 45
	   //  surname: Simpson
	   //  forename: Homer
       In the example we insert some line edits into a dictionary, then iterate over the dictionary printing the strings associated with those
       line edits.

       Note that the traversal order is arbitrary; you are not guaranteed any particular order.

       Multiple iterators may independently traverse the same dictionary. A QAsciiDict knows about all the iterators that are operating on the
       dictionary. When an item is removed from the dictionary, QAsciiDict updates all the iterators that are referring to the removed item to
       point to the next item in the (arbitrary) traversal order.

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

MEMBER FUNCTION DOCUMENTATION

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

QAsciiDictIterator::~QAsciiDictIterator ()
       Destroys the iterator.

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

       See also isEmpty().

type * QAsciiDictIterator::current () const
       Returns a pointer to the current iterator item.

const char * QAsciiDictIterator::currentKey () const
       Returns a pointer to the key for the current iterator item.

bool QAsciiDictIterator::isEmpty () const
       Returns TRUE if the dictionary is empty, i.e. count() == 0, otherwise returns FALSE.

       See also count().

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

type * QAsciiDictIterator::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 returned.

type * QAsciiDictIterator::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 returned.

type * QAsciiDictIterator::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 * QAsciiDictIterator::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 0.
