NAMEQGLayoutIterator - 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
DESCRIPTIONThe 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.
