       \section2 Animation
 
         Graphics View supports animation at several levels. You can easily
-        assemble animation paths by associating a QGraphicsItemAnimation with
-        your item. This allows timeline controlled animations that operate at
-        a steady speed on all platforms (although the frame rate may vary
-        depending on the platform's performance).  QGraphicsItemAnimation
-        allows you to create a path for an item's position, rotation, scale,
-        shear and translation. The animation can be controlled by a QSlider,
-        or more commonly by QTimeLine.
+        assemble animation by using the Animation Framework. For that you'll
+		need your items to inherit from QGraphicsObject and associate 
+		QPropertyAnimation with them. QPropertyAnimation allows to animate any 
+		QObject property.
 
         Another option is to create a custom item that inherits from QObject
         and QGraphicsItem. The item can the set up its own timers, and control

     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
+    To do this, you can register an interpolator function for a given
+    type. This function takes 3 parameters: the start value, the end value
+    and the current progress.
+
+    Example:
+    \code
+        QVariant myColorInterpolator(const QColor &start, const QColor &end, qreal progress)
+        {
+            ...
+            return QColor(...);
+        }
+        ...
+        qRegisterAnimationInterpolator<QColor>(myColorInterpolator);
+    \endcode
+
+    Another option is to reimplement interpolated(), which returns
     interpolation values for the value being interpolated.
