NAME

       QGLayoutIterator - Abstract base class of internal layout iterators

SYNOPSIS

       #include <qlayout.h>

   Public Members
       virtual ~QGLayoutIterator ()
       virtual QLayoutItem * next () = 0
       virtual QLayoutItem * current () = 0
       virtual QLayoutItem * takeCurrent () = 0

DESCRIPTION

       The QGLayoutIterator class is an abstract base class of internal layout iterators.

       (This class is not OpenGL related, it just happens to start with the letters QGL...)

       Subclass this class to create a custom layout. The functions that must be implemented are next(), current(), and takeCurrent().

       The QGLayoutIterator implements the functionality of QLayoutIterator. Each subclass of QLayout needs a QGLayoutIterator subclass.

       See also Widget Appearance and Style and Layout Management.

MEMBER FUNCTION DOCUMENTATION

QGLayoutIterator::~QGLayoutIterator () [virtual]
       Destroys the iterator

QLayoutItem * QGLayoutIterator::current () [pure virtual]
       Implemented in subclasses to return the current item, or 0 if there is no current item.

       Examples:

QLayoutItem * QGLayoutIterator::next () [pure virtual]
       Implemented in subclasses to move the iterator to the next item and return that item, or 0 if there is no next item.

       Examples:

QLayoutItem * QGLayoutIterator::takeCurrent () [pure virtual]
       Implemented in subclasses. The function must remove the current item from the layout without deleting it, move the iterator to the next
       item and return the removed item, or 0 if no item was removed.

       Examples:
