+    \class Q3PtrCollection
+    \reentrant
+    \brief The Q3PtrCollection class is the base class of most pointer-based Qt collections.
+
+    \compat
+
+    The Q3PtrCollection class is an abstract base class for the Qt
+    collection classes QDict, Q3PtrList,
+    etc.
+
+    A Q3PtrCollection only knows about the number of objects in the
+    collection and the deletion strategy (see setAutoDelete()).
+
+    A collection is implemented using the \c Item (generic collection
+    item) type, which is a \c void*. The template classes that create
+    the real collections cast the \c Item to the required type.
+*/
+
+
+/*!
+    \typedef Q3PtrCollection::Item
+
+    This type is the generic "item" in a Q3PtrCollection.
+*/
+
+
+/*!
+    \fn Q3PtrCollection::Q3PtrCollection()
+
+    Constructs a collection. The constructor is protected because
+    Q3PtrCollection is an abstract class.
+*/
+
+/*!
+    \fn Q3PtrCollection::Q3PtrCollection( const Q3PtrCollection & source )
+
+    Constructs a copy of \a source with autoDelete() set to false. The
+    constructor is protected because Q3PtrCollection is an abstract
+    class.
+
+    Note that if \a source has autoDelete turned on, copying it will
+    risk memory leaks, reading freed memory, or both.
+*/
+
+/*!
+    \fn Q3PtrCollection::~Q3PtrCollection()
+
+    Destroys the collection. The destructor is protected because
+    Q3PtrCollection is an abstract class.
+*/
+
+
+/*!
+    \fn bool Q3PtrCollection::autoDelete() const
+
+    Returns the setting of the auto-delete option. The default is false.
+
+    \sa setAutoDelete()
+*/
+
+/*!
+    \fn void Q3PtrCollection::setAutoDelete( bool enable )
+
+    Sets the collection to auto-delete its contents if \a enable is
+    true and to never delete them if \a enable is false.
+
+    If auto-deleting is turned on, all the items in a collection are
+    deleted when the collection itself is deleted. This is convenient
+    if the collection has the only pointer to the items.
+
+    The default setting is false, for safety. If you turn it on, be
+    careful about copying the collection - you might find yourself
+    with two collections deleting the same items.
+
+    Note that the auto-delete setting may also affect other functions
+    in subclasses. For example, a subclass that has a remove()
+    function will remove the item from its data structure, and if
+    auto-delete is enabled, will also delete the item.
+
+    \sa autoDelete()

+
+/*!
+    \fn virtual void Q3PtrCollection::clear()
+
+    Removes all objects from the collection. The objects will be
+    deleted if auto-delete has been enabled.
+
+    \sa setAutoDelete()
+*/
+
+/*!
+    \fn void Q3PtrCollection::deleteItem( Item d )
+
+    Reimplement this function if you want to be able to delete items.
+
+    Deletes an item that is about to be removed from the collection.
+
+    This function has to reimplemented in the collection template
+    classes, and should \e only delete item \a d if auto-delete has
+    been enabled.
+
+    \warning If you reimplement this function you must also
+    reimplement the destructor and call the virtual function clear()
+    from your destructor. This is due to the way virtual functions and
+    destructors work in C++: Virtual functions in derived classes
+    cannot be called from a destructor. If you do not do this, your
+    deleteItem() function will not be called when the container is
+    destroyed.

+    Virtual function that creates a copy of an object that is about to
+    be inserted into the collection.
+
+    The default implementation returns the \a d pointer, i.e. no copy

+
+    This function is seldom reimplemented in the collection template
+    classes. It is not common practice to make a copy of something
+    that is being inserted.
