+ \class QValueStack qvaluestack.h
+ \brief The QValueStack class is a value-based template class that provides a stack.
+
+ \ingroup qtl
+ \ingroup tools
+ \ingroup shared
+ \mainclass
+ \reentrant
+
+ Define a template instance QValueStack\<X\> to create a stack of
+ values that all have the class X. QValueStack is part of the \link
+ qtl.html Qt Template Library\endlink.
+
+ Note that QValueStack does not store pointers to the members of
+ the stack; it holds a copy of every member. That is why these
+ kinds of classes are called "value based"; QPtrStack, QPtrList,
+ QDict, etc., are "pointer based".
+
+ 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(). The top() function provides access to the topmost item
+ without removing it.
+
+ Example:
+ \code
+ QValueStack<int> stack;
+ stack.push( 1 );
+ stack.push( 2 );
+ stack.push( 3 );
+ while ( ! stack.isEmpty() )
+ cout << "Item: " << stack.pop() << endl;
+
+ // Output:
+ // Item: 3
+ // Item: 2
+ // Item: 1
+ \endcode
+
+ QValueStack is a specialized QValueList provided for convenience.
+ All of QValueList's functionality also applies to QPtrStack, for
+ example the facility to iterate over all elements using
+ QValueStack<T>::Iterator. See QValueListIterator for further
+ details.
+
+ Some classes cannot be used within a QValueStack, for example
+ everything derived from QObject and thus all classes that
+ implement widgets. Only values can be used in a QValueStack. To
+ qualify as a value, the class must provide
+ \list
+ \i a copy constructor;
+ \i an assignment operator;
+ \i a default constructor, i.e. a constructor that does not take any arguments.
+ \endlist
+
+ Note that C++ defaults to field-by-field assignment operators and
+ copy constructors if no explicit version is supplied. In many
+ cases this is sufficient.

+/*!
+ \fn QValueStack::QValueStack()
+
+ Constructs an empty stack.
+*/
+
+/*!
+ \fn QValueStack::~QValueStack()
+
+ Destroys the stack. References to the values in the stack and all
+ iterators of this stack become invalidated. Because QValueStack is
+ highly tuned for performance, you won't see warnings if you use
+ invalid iterators because it is impossible for an iterator to
+ check whether or not it is valid.
