NAME

SYNOPSIS

10
11   Public Members
12       virtual ~QGLayoutIterator ()
13       virtual QLayoutItem * next () = 0
14       virtual QLayoutItem * current () = 0
15       virtual QLayoutItem * takeCurrent () = 0

DESCRIPTION

18       The QGLayoutIterator class is an abstract base class of internal layout
19       iterators.
20
21       (This class is not OpenGL related, it just happens to start with the
22       letters QGL...)
23
24       Subclass this class to create a custom layout. The functions that must
25       be implemented are next(), current(), and takeCurrent().
26
27       The QGLayoutIterator implements the functionality of QLayoutIterator.
28       Each subclass of QLayout needs a QGLayoutIterator subclass.

MEMBER FUNCTION DOCUMENTATION

QGLayoutIterator::~QGLayoutIterator () [virtual]

34       Destroys the iterator
35

QLayoutItem * QGLayoutIterator::current () [pure virtual]

37       Implemented in subclasses to return the current item, or 0 if there is
38       no current item.
39
40       Examples:
41

QLayoutItem * QGLayoutIterator::next () [pure virtual]

43       Implemented in subclasses to move the iterator to the next item and
44       return that item, or 0 if there is no next item.
45
46       Examples:
47

QLayoutItem * QGLayoutIterator::takeCurrent () [pure virtual]

49       Implemented in subclasses. The function must remove the current item
50       from the layout without deleting it, move the iterator to the next item
51       and return the removed item, or 0 if no item was removed.
