+    \class QStack
+    \brief The QStack class is a template class that provides a stack.
+
+    \ingroup tools
+    \ingroup shared
+    \mainclass
+    \reentrant
+
+    QStack\<T\> is one of Qt's generic \l{container classes}. It implements
+    a stack data structure for items of a same type.
+
+    A stack is a last in, first out (LIFO) structure. Items are added
+    to the top of the stack using push() and retrieved from the top
+    using pop(). The top() function provides access to the topmost
+    item without removing it.
+
+    Example:
+
+    \snippet doc/src/snippets/qstack/main.cpp 0
+
+    The example will output 3, 2, 1 in that order.
+
+    QStack inherits from QVector. All of QVector's functionality also
+    applies to QStack. For example, you can use isEmpty() to test
+    whether the stack is empty, and you can traverse a QStack using
+    QVector's iterator classes (for example, QVectorIterator). But in
+    addition, QStack provides three convenience functions that make
+    it easy to implement LIFO semantics: push(), pop(), and top().
+
+    QStack's value type must be an \l{assignable data type}. This
+    covers most data types that are commonly used, but the compiler
+    won't let you, for example, store a QWidget as a value; instead,
+    store a QWidget *.
