     \class QAbstractAnimation
     \ingroup animation
-    \brief The QAbstractAnimation class provides an abstract base class for animations.
+    \brief The QAbstractAnimation class is the base of all animations.
     \since 4.5
     \preliminary
 
-    This class is part of \l{The Animation Framework}. It serves as a base class
-    for standard animations and groups, with functions for shared
-    functionality, and it also makes it easy for you to define custom
+    The class defines the functions for the functionality shared by
+    all animations. By inheriting this class, you can create custom
     animations that plug into the rest of the animation framework.
 
-    If you want to create an animation, you should look at the two subclasses,
-    QVariantAnimation and QAnimationGroup, instead.
-
-    QAbstractAnimation provides an interface for the current time and
-    duration, the iteration count, and the state of an animation. These properties
-    define the base functionality common to all animations in Qt. The virtual
-    duration() function returns the local duration of the animation; i.e., for
-    how long the animation should update the current time before
-    looping. Subclasses can implement this function differently; for example,
-    QVariantAnimation returns the duration of a simple animated property, whereas
-    QAnimationGroup returns the duration of a set or sequence of
-    animations. You can also set a loop count by calling setIterationCount(); a
-    iteration count of 2 will let the animation run twice (the default value is
-    1).
-
-    Like QTimeLine, QAbstractAnimation also provides an interface for starting
-    and stopping an animation, and for tracking its progress. You can call the
-    start() slot to start the animation. When the animation starts, the
-    stateChanged() signal is emitted, and state() returns Running. If you call the
-    stop() slot, the stateChanged() signal is emitted, and state() returns
-    Stopped. If you call the pause() slot, the stateChanged() signal is emitted
-    and state() returns Paused. If the animation reaches the end, the finished()
-    signal is emitted. You can check the current state by calling state().
-
-    QAbstractAnimation provides two functions that are pure virtual, and must
-    be reimplemented in a subclass: duration(), and updateCurrentTime(). The
-    duration() function lets you report a duration for the animation (a return
-    value of -1 signals that the animation runs forever until explicitly
-    stopped). The current time is delivered by the framework through calls to
-    updateCurrentTime(). By reimplementing this function, you can track the
-    animation progress and update your target objects accordingly. By
-    reimplementing updateState(), you can track the animation's state
-    changes, which is particularily useful for animations that are not driven
-    by time.
-
-    \sa QVariantAnimation, QAnimationGroup, {The Animation Framework}
+    The progress of an animation is given by its current time
+    (currentTime()), which is measured in milliseconds from the start
+    of the animation (0) to its end (duration()). The value is updated
+    automatically while the animation is running. It can also be set
+    directly with setCurrentTime().
+
+    At any point an animation is in one of three states:
+    \l{QAbstractAnimation::}{Running},
+    \l{QAbstractAnimation::}{Stopped}, or
+    \l{QAbstractAnimation::}{Paused}--as defined by the
+    \l{QAbstractAnimation::}{State} enum. The current state can be
+    changed by calling start(), stop(), pause(), or resume(). An
+    animation will always reset its \l{currentTime()}{current time}
+    when it is started. If paused, it will continue with the same
+    current time when resumed. When an animation is stopped, it cannot
+    be resumed, but will keep its current time (until started again).
+    QAbstractAnimation will emit stateChanged() whenever its state
+    changes.
+
+    An animation can loop any number of times by setting the loopCount
+    property. When an animation's current time reaches its duration(),
+    it will reset the current time and keep running. A loop count of 1
+    (the default value) means that the animation will run one time.
+    Note that a duration of -1 means that the animation will run until
+    stopped; the current time will increase indefinitely. When the
+    current time equals duration() and the animation is in its
+    final loop, the \l{QAbstractAnimation::}{Stopped} state is
+    entered, and the finished() signal is emitted.
+
+    QAbstractAnimation provides pure virtual functions used by
+    subclasses to track the progress of the animation: duration() and
+    updateCurrentTime(). The duration() function lets you report a
+    duration for the animation (as discussed above). The current time
+    is delivered by the animation framework through calls to
+    updateCurrentTime(). By reimplementing this function, you can
+    track the animation progress. Note that neither the interval
+    between calls nor the number of calls to this function are
+    defined; though, it will normally be 60 updates per second.
+
+    By reimplementing updateState(), you can track the animation's
+    state changes, which is particularly useful for animations that
+    are not driven by time.

-    QAnimationGroup represents a group of animations, such as parallel or sequential,
-    and lets you combine different animations into one. The group manages any animation
-    that inherits QAbstractAnimation. By combining groups, you can easily construct
-    complex animation graphs.
-
-    The QAnimationGroup base class provides methods for adding and retrieving animations.
-    Besides that, you can remove animations by calling remove(), and clear the animation
-    group by calling clearAnimations(). You may keep track of changes in the group's animations by
-    listening to QEvent::ChildAdded and QEvent::ChildRemoved events.
-
-    QAnimationGroup takes ownership of the animations it manages, and ensures that they are
-    deleted when the animation group is deleted.
+    An animation group is a container for animations (subclasses of
+    QAbstractAnimation). A group is usually responsible for managing
+    the \l{QAbstractAnimation::State}{state} of its animations, i.e.,
+    it decides when to start, stop, resume, and pause them. Currently,
+    Qt provides two such groups: QParallelAnimationGroup and
+    QSequentialAnimationGroup. Look up their class descriptions for
+    details.
+
+    Since QAnimationGroup inherits from QAbstractAnimation, you can
+    combine groups, and easily construct complex animation graphs.
+    You can query QAbstractAnimation for the group it belongs to
+    (using the \l{QAbstractAnimation::}{group()} function).
+
+    To start a top-level animation group, you simply use the
+    \l{QAbstractAnimation::}{start()} function from
+    QAbstractAnimation. By a top-level animation group, we think of a
+    group that itself is not contained within another group. Starting
+    sub groups directly is not supported, and may lead to unexpected

     \class QPropertyAnimation
-    \brief The QPropertyAnimation class animates properties for QObject(and QWidget)
+    \brief The QPropertyAnimation class animates Qt properties
     \ingroup animation
     \preliminary
 
-    This class is part of {The Animation Framework}.  You can use QPropertyAnimation
-    by itself as a simple animation class, or as part of more complex
-    animations through QAnimationGroup.
-
-    The most common way to use QPropertyAnimation is to construct an instance 
-    of it by passing a pointer to a QObject or a QWidget, and the name of the
-    property you would like to animate to QPropertyAnimation's constructor.
-
-    The start value of the animation is optional. If you do not set any start
-    value, the animation will operate on the target's current property value
-    at the point when the animation was started. You can call setStartValue()
-    to set the start value, and setEndValue() to set the target value for
-    the animated property.
-
-    Animations can operate on QObjects and QWidgets. You can choose to assign a
-    target object by either calling setTargetObject() or by passing a QObject
-    pointer to QPropertyAnimation's constructor.
+    QPropertyAnimation interpolates over \l{Qt's Property System}{Qt
+    properties}. As property values are stored in \l{QVariant}s, the
+    class inherits QVariantAnimation, and supports animation of the
+    same \l{QVariant::Type}{variant types} as its super class. 
+
+    A class declaring properties must be a QObject. To make it
+    possible to animate a property, it must provide a setter (so that
+    QPropertyAnimation can set the property's value). Note that this
+    makes it possible to animate many of Qt's widgets. Let's look at
+    an example:
+    
+    \code
+        QPropertyAnimation animation(myWidget, "geometry");
+        animation.setDuration(10000);
+        animation.setStartValue(QRect(0, 0, 100, 30));
+        animation.setEndValue(QRect(250, 250, 100, 30));
+
+        animation.start();
+    \endcode
+
+    The property name and the QObject instance of which property
+    should be animated are passed to the constructor. You can then
+    specify the start and end value of the property. The procedure is
+    equal for properties in classes you have implemented
+    yourself--just check with QVariantAnimation that your QVariant
+    type is supported.
+
+    The QVariantAnimation class description explains how to set up the
+    animation in detail. Note, however, that if a start value is not
+    set, the property will start at the value it had when the
+    QPropertyAnimation instance was created.
+
+    QPropertyAnimation works like a charm on its own. For complex
+    animations that, for instance, contain several objects,
+    QAnimationGroup is provided. An animation group is an animation
+    that can contain other animations, and that can manage when its
+    animations are played. Look at QParallelAnimationGroup for an
+    example.

+    This class is part of \l{The Animation Framework}. It serves as a
+    base class for property and item animations, with functions for
+    shared functionality.
+
+    QVariantAnimation cannot be used directly as it is an abstract
+    class; it does not implement
+    \l{QAbstractAnimation::}{updateCurrentValue()} from
+    QAbstractAnimation. The class performs interpolation over
+    \l{QVariant}s, but leaves using the interpolated values to its
+    subclasses. Currently, Qt provides QPropertyAnimation, which
+    animates Qt \l{Qt's Property System}{properties}. See the
+    QPropertyAnimation class description if you wish to animate such
+    properties.
+    
     You can then set start and end values for the property by calling
     setStartValue() and setEndValue(), and finally call start() to
-    start the animation. When control goes back to the event loop, QVariantAnimation
-    will interpolate the property of the target object and emit the valueChanged
-    signal. To react to a change in the current value you have to reimplement the
-    updateCurrentValue virtual method.
-
-    There are two ways to affect how QVariantAnimation interpolates the values.
-    You can set an easing curve by calling setEasingCurve(), and configure the
-    duration by calling setDuration(). You can change how the QVariants are
-    interpolated by creating a subclass of QVariantAnimation, and reimplementing the
-    virtual interpolated() function.

+    property of the target object and emit valueChanged(). To react to
+    a change in the current value you have to reimplement the
+    updateCurrentValue() virtual function.
+
+    It is also possible to set values at specified steps situated
+    between the start and end value. The interpolation will then
+    touch these points at the specified steps. Note that the start and
+    end values are defined as the key values at 0.0 and 1.0.

+    setDuration(). You can change how the QVariants are interpolated
+    by creating a subclass of QVariantAnimation, and reimplementing
+    the virtual interpolated() function.
+
+    Subclassing QVariantAnimation can be an alternative if you have
+    \l{QVariant}s that you do not wish to declare as Qt properties.
+    Note, however, that you in most cases will be better off declaring
+    your QVariant as a property.
+
+    Not all QVariant types are supported. Below is a list of currently
+    supported QVariant types:
+
+    \list
+        \o \l{QMetaType::}{Int}
+        \o \l{QMetaType::}{Double}
+        \o \l{QMetaType::}{Float}
+        \o \l{QMetaType::}{QLine}
+        \o \l{QMetaType::}{QLineF}
+        \o \l{QMetaType::}{QPoint}

+        \o \l{QMetaType::}{QSizeF}
+        \o \l{QMetaType::}{QRect}
+        \o \l{QMetaType::}{QRectF}
+    \endlist 
+
+    If you need to interpolate other variant types, including custom
+    types, you have to implement interpolation for these yourself.
+    You do this by reimplementing interpolated(), which returns
+    interpolation values for the value being interpolated.

-   \enum QAbstractState::RestorePolicy
-
-   This enum specifies the restore policy type for a state. The restore policy
-   takes effect when the machine enters a state which sets one or more
-   properties. If the restore policy of the state is set to RestoreProperties,
-   the state machine will save the original value of the property before the
-   new value is set.
-
-   Later, when the machine either enters a state which has its restore policy
-   set to DoNotRestoreProperties or when it enters a state which does not set
-   a value for the given property, the property will automatically be restored
-   to its initial value.
-
-   Only one initial value will be saved for any given property. If a value for a property has 
-   already been saved by the state machine, it will not be overwritten until the property has been
-   successfully restored. Once the property has been restored, the state machine will clear the 
-   initial value until it enters a new state which sets the property and which has RestoreProperties
-   as its restore policy.
-
-   \value GlobalRestorePolicy The restore policy for the state should be retrieved using 
-          QStateMachine::globalRestorePolicy()
-   \value DoNotRestoreProperties The state machine should not save the initial values of properties 
-          set in the state and restore them later.

-    \class QItemAnimation
-    \brief The QItemAnimation class animates properties for QGraphicsItem
-    \since 4.5
-    \ingroup animation
-    \preliminary
-
-    This class is part of {The Animation Framework}.  You can use QItemAnimation
-    by itself as a simple animation class, or as part of more complex
-    animations through QAnimationGroup.
-
-    The most common way to use QItemAnimation is to construct an instance
-    of it by passing a pointer to a QGraphicsItem and the property you
-    would like to animate to QItemAnimation's constructor.
-
-    The start value of the animation is optional. If you do not set any start
-    value, the animation will operate on the target's current property value
-    at the point when the animation was started. You can call setStartValue()
-    to set the start value, and setEndValue() to set the target value for
-    the animated property.
-
-    You can choose to assign a target item by either calling setTargetItem()
-    or by passing a QGraphicsItem pointer to QVariantAnimation's constructor.
