.SH DESCRIPTION
The QStack class is a template class that provides a stack.
.PP
QStack is implemented as a template class. Define a template instance QStack<X> to create a stack that operates on pointers to X, or X*.
.PP
A stack is a Last In, First Out (LIFO) structure. Items are added to the top of the stack with push() and retrieved from the top with pop().
.PP

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QStack::QStack ()"
Creates and empty stack.
.SH "QStack::QStack ( const QStack<type> & s )"
Creates a stack by making a shallow copy of another stack.
.SH "QStack::~QStack ()"
Destroys the stack. All items will be deleted if autoDelete() is TRUE.
.SH "QStack::operator type* () const"
Returns a reference to the top item on the stack (most recently pushed). The stack is not changed.
.SH "bool QStack::autoDelete () const"
The same as QCollection::autoDelete().
.PP
See also setAutoDelete().
.SH "void QStack::clear () \fC[virtual]\fR"
Removes all items from the stack, deleting them if autoDelete() is TRUE.
.PP
See also remove().
.PP
Reimplemented from QCollection.
.SH "uint QStack::count () const \fC[virtual]\fR"
Returns the number of items in the stack.
.PP
See also isEmpty().
.PP
Reimplemented from QCollection.
.SH "type* QStack::current () const"
Returns a reference to the top item on the stack (most recently pushed). The stack is not changed.
.SH "bool QStack::isEmpty () const"
Returns TRUE is the stack contains no elements to be popped
.SH "QStack<type>& QStack::operator= ( const QStack<type> & s )"
Sets the contents of this stack by making a shallow copy of another stack. Elements currently in this stack will be deleted if autoDelete() is TRUE.
.SH "type* QStack::pop ()"
Removes the top item from the stack and returns it.
.SH "void QStack::push ( const type * d )"
Adds an element to the top of the stack. Last in, first out.
.SH "bool QStack::remove ()"
Removes the top item from the stack and deletes it if autoDelete() is TRUE. Returns TRUE if there was an item to pop.
.PP
See also clear().
.SH "void QStack::setAutoDelete ( bool enable )"
The same as QCollection::setAutoDelete().
.PP
See also autoDelete().
.SH "type* QStack::top () const"
Returns a reference to the top item on the stack (most recently pushed).
The stack is not changed.
