.SH DESCRIPTION
The abstract base class of internal layout iterators.
.PP
To be subclassed by custom layout implementors. The functions that need to be implemented are next(), current() and takeCurrent().
.PP
The QGLayoutIterator implements the functionality of QLayoutIterator. Each subclass of QLayout needs a QGLayoutIterator subclass.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QGLayoutIterator::~QGLayoutIterator () \fC[virtual]\fR"
Destroys the iterator.
.SH "QLayoutItem * QGLayoutIterator::current () \fC[virtual]\fR"
Implemented in subclasses to return the current item, or 0 if there is no current item.
.SH "QLayoutItem * QGLayoutIterator::next () \fC[virtual]\fR"
Implemented in subclasses to move the iterator to the next item and return that item, or 0 if there is no next item.
.SH "QLayoutItem * QGLayoutIterator::takeCurrent () \fC[virtual]\fR"
Implemented in subclasses to 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.
