Items are added to the top of the stack with push() and retrieved from the top with pop(). Use top() to get a reference to the top element without changing the stack. +.PP +You can control the stack's deletion policy with setAutoDelete(). +.PP +For compatibility with the QPtrCollection classes current() and remove() are provided; they both operate on the top(). +.PP +See also QPtrList, QPtrQueue, and Non-GUI Classes. +.SH MEMBER FUNCTION DOCUMENTATION +.SH "QPtrStack::QPtrStack ()" +Creates an empty stack. +.SH "QPtrStack::QPtrStack ( const QPtrStack<type> & s )" +Creates a stack by making a shallow copy of another stack \fIs\fR. +.SH "QPtrStack::~QPtrStack ()" +Destroys the stack. All items will be deleted if autoDelete() is TRUE. +.SH "bool QPtrStack::autoDelete () const" +The same as QPtrCollection::autoDelete(). +.PP +See also setAutoDelete(). +.SH "void QPtrStack::clear ()" +Removes all items from the stack, deleting them if autoDelete() is TRUE. +.PP +See also remove(). +.SH "uint QPtrStack::count () const" +Returns the number of items in the stack. +.PP +See also isEmpty(). +.SH "type * QPtrStack::current () const" +Returns a pointer to the top item on the stack (most recently pushed). The stack is not changed. Returns 0 if the stack is empty. +.SH "bool QPtrStack::isEmpty () const" +Returns TRUE if the stack contains no elements; otherwise returns FALSE. +.SH "QPtrStack::operator type * () const" +Returns a pointer to the top item on the stack (most recently pushed). The stack is not changed. Returns 0 if the stack is empty. +.SH "QPtrStack<type> & QPtrStack::operator= ( const QPtrStack<type> & s )" +Sets the contents of this stack by making a shallow copy of another stack \fIs\fR. Elements currently in this stack will be deleted if autoDelete() is TRUE. +.SH "type * QPtrStack::pop ()" +Removes the top item from the stack and returns it. The stack must not be empty. +.SH "void QPtrStack::push ( const type * d )" +Adds an element \fId\fR to the top of the stack. Last in, first out. +.SH "QDataStream & QPtrStack::read ( QDataStream & s, QPtrCollection::Item & item )\fC [virtual protected]\fR" +Reads a stack item, \fIitem\fR, from the stream \fIs\fR and returns a reference to the stream. +.PP +The default implementation sets \fIitem\fR to 0. +.PP +See also write(). +.SH "bool QPtrStack::remove ()" +Removes the top item from the stack and deletes it if autoDelete() is TRUE. Returns TRUE if there was an item to pop; otherwise returns FALSE. +.PP +See also clear(). +.SH "void QPtrStack::setAutoDelete ( bool enable )" +Defines whether this stack auto-deletes its contents. The same as QPtrCollection::setAutoDelete(). +.PP +If \fIenable\fR is TRUE the stack auto-deletes its contents; if \fIenable\fR is FALSE the stack does not delete its contents. +.PP +See also autoDelete(). +.SH "type * QPtrStack::top () const" +Returns a pointer to the top item on the stack (most recently pushed). The stack is not changed. Returns 0 if the stack is empty. +.SH "QDataStream & QPtrStack::write ( QDataStream & s, QPtrCollection::Item item ) const\fC [virtual protected]\fR" +Writes a stack item, \fIitem\fR, to the stream \fIs\fR and returns a reference to the stream. +.PP +The default implementation does nothing. +.PP +See also read(). + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/ntqptrstack.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
