DESCRIPTION
       The QValueListIterator class provides an iterator for QValueList.

       An iterator is a class for accessing the items of a container class: a generalization of
       the index in an array. A pointer into a "const char *" and an index into an "int[]" are
       both iterators, and the general idea is to provide that functionality for any data
       structure.

       The QValueListIterator class is an iterator for QValueList instantiations. You can create
       the appropriate iterator type by using the iterator typedef provided by QValueList.

       The only way to access the items in a QValueList is to use an iterator.

       Example (see QValueList for the complete code):

	   EmployeeList::iterator it;
	   for ( it = list.begin(); it != list.end(); ++it )
	       cout << (*it).surname().latin1() << ", " <<
		       (*it).forename().latin1() << " earns " <<
		       (*it).salary() << endl;
	   // Output:
	   // Doe, John earns 50000
	   // Williams, Jane earns 80000
	   // Hawthorne, Mary earns 90000
	   // Jones, Tom earns 60000

       QValueList is highly optimized for performance and memory usage. This means that you must
       be careful: QValueList does not know about all its iterators and the iterators don't know
       to which list they belong. This makes things very fast, but if you're not careful, you can
       get spectacular bugs. Always make sure iterators are valid before dereferencing them or
       using them as parameters to generic algorithms in the STL or the QTL.

       Using an invalid iterator is undefined (your application will probably crash). Many Qt
       functions return const value lists; to iterate over these you should make a copy and
       iterate over the copy.

       For every Iterator there is a ConstIterator. When accessing a QValueList in a const
       environment or if the reference or pointer to the list is itself const, then you must use
       the ConstIterator. Its semantics are the same as the Iterator, but it only returns const
       references.

       See also QValueList, QValueListConstIterator, Qt Template Library Classes, and Non-GUI
       Classes.

   Member Type Documentation
QValueListIterator::pointer
       Pointer to value_type.

QValueListIterator::reference
       Reference to value_type.

QValueListIterator::value_type
       The type of value, T.

MEMBER FUNCTION DOCUMENTATION
QValueListIterator::QValueListIterator ()
       Creates un uninitialized iterator.

QValueListIterator::QValueListIterator ( const QValueListIterator<T> & it )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Constructs a copy of the iterator it.

bool QValueListIterator::operator!= ( const QValueListIterator<T> & it ) const
       Compares this iterator and it and returns TRUE if they point to different items; otherwise
       returns FALSE.

T &; QValueListIterator::operator* ()
       Asterisk operator. Returns a reference to the current iterator item.

const T &; QValueListIterator::operator* () const
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Asterisk operator. Returns a reference to the current iterator item.

QValueListIterator<;T> & QValueListIterator::operator++ ()
       Prefix ++ makes the succeeding item current and returns an iterator pointing to the new
       current item. The iterator cannot check whether it reached the end of the list.
       Incrementing the iterator returned by end() causes undefined results.

QValueListIterator<;T> QValueListIterator::operator++ ( int )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Postfix ++ makes the succeeding item current and returns an iterator pointing to the new
       current item. The iterator cannot check whether it reached the end of the list.
       Incrementing the iterator returned by end() causes undefined results.

QValueListIterator<;T> & QValueListIterator::operator+= ( int j )
       Postfix -- jumps j steps forward in the list. The iterator cannot check whether it reached
       the end of the list. Jumping past the end() causes undefined results.

QValueListIterator<;T> & QValueListIterator::operator-- ()
       Prefix -- makes the previous item current and returns an iterator pointing to the new
       current item. The iterator cannot check whether it reached the beginning of the list.
       Decrementing the iterator returned by begin() causes undefined results.

QValueListIterator<;T> QValueListIterator::operator-- ( int )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Postfix -- makes the previous item current and returns an iterator pointing to the new
       current item. The iterator cannot check whether it reached the beginning of the list.
       Decrementing the iterator returned by begin() causes undefined results.

QValueListIterator<;T> & QValueListIterator::operator-= ( int j )
       Postfix -- jumps j steps backward in the list. The iterator cannot check whether it
       reached the beginning of the list. Jumping past begin() causes undefined results.

bool QValueListIterator::operator== ( const QValueListIterator<T> & it ) const
       Compares this iterator and it and returns TRUE if they point to the same item; otherwise
       returns FALSE.
