NAME
TQGLayoutIterator - Abstract base class of internal layout iterators

SYNOPSIS
#include <tqlayout.h>

  Public Members
virtual ~TQGLayoutIterator ()
virtual TQLayoutItem * next () = 0
virtual TQLayoutItem * current () = 0
virtual TQLayoutItem * takeCurrent () = 0

DESCRIPTION
The TQGLayoutIterator class is an abstract base class of internal layout iterators.

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

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

The TQGLayoutIterator implements the functionality of TQLayoutIterator. Each subclass of TQLayout needs a TQGLayoutIterator subclass.

See also Widget Appearance and Style and Layout Management.

TQGLayoutIterator::~TQGLayoutIterator () [virtual]

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

Examples:

TQLayoutItem * TQGLayoutIterator::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:

TQLayoutItem * TQGLayoutIterator::takeCurrent () [pure virtual]
