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 DOCUMENTATIONQGLayoutIterator::~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.
