.SH DESCRIPTION
|
|
The QGLayoutIterator class is an abstract base class of internal layout iterators.
|
|
.PP
|
|
(This class is \fInot\fR OpenGL related, it just happens to start with the letters QGL...)
|
|
.PP
|
|
Subclass this class to create a custom layout. The functions that must be implemented are next(), current(), and takeCurrent().
|
|
.PP
|
|
The QGLayoutIterator implements the functionality of QLayoutIterator. Each subclass of QLayout needs a QGLayoutIterator subclass.
|
|
.PP
|
|

.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QGLayoutIterator::~QGLayoutIterator ()\fC [virtual]\fR"
|
|
Destroys the iterator
|
|
.SH "QLayoutItem * QGLayoutIterator::current ()\fC [pure virtual]\fR"
|
|
Implemented in subclasses to return the current item, or 0 if there is no current item.
|
|
.PP
|
|
Examples:
|
|
.)l customlayout/border.cpp, customlayout/card.cpp, and customlayout/flow.cpp.
|
|
.SH "QLayoutItem * QGLayoutIterator::next ()\fC [pure 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.
|
|
.PP
|
|
Examples:
|
|
.)l customlayout/border.cpp, customlayout/card.cpp, and customlayout/flow.cpp.
|
|
.SH "QLayoutItem * QGLayoutIterator::takeCurrent ()\fC [pure virtual]\fR"
|
|
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.
