# qglayoutiterator(3qt)

Abstract base class of internal layout iterators

## 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:
