+    \class QPtrStack qptrstack.h
+    \brief The QPtrStack class is a template class that provides a stack.
+
+    \ingroup tools
+
+    QValueStack is an STL-compatible alternative to this class.
+
+    Define a template instance QPtrStack\<X\> to create a stack that
+    operates on pointers to X, (X*). 
+
+    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(). Use top() to get a reference to the top element
+    without changing the stack.
+
+    You can control the stack's deletion policy with setAutoDelete().
+
+    For compatibility with the QPtrCollection classes current() and
+    remove() are provided; they both operate on the top().
+
