+    \since 4.8
+    \class QIdentityProxyModel
+    \brief The QIdentityProxyModel class proxies its source model unmodified
+
+    \ingroup model-view
+
+    QIdentityProxyModel can be used to forward the structure of a source model exactly, with no sorting, filtering or other transformation.
+    This is similar in concept to an identity matrix where A.I = A.
+
+    Because it does no sorting or filtering, this class is most suitable to proxy models which transform the data() of the source model.
+    For example, a proxy model could be created to define the font used, or the background colour, or the tooltip etc. This removes the
+    need to implement all data handling in the same class that creates the structure of the model, and can also be used to create
+    re-usable components.
+
+    This also provides a way to change the data in the case where a source model is supplied by a third party which can not be modified.

     \brief The QRadialGradient class is used in combination with QBrush to
     specify a radial gradient brush.
 
-    Radial gradients interpolate colors between a focal point and end
-    points on a circle surrounding it. Outside the end points the
-    gradient is either padded, reflected or repeated depending on the
-    currently set \l {QGradient::Spread}{spread} method:
+    Qt supports both simple and extended radial gradients.
+
+    Simple radial gradients interpolate colors between a focal point and end
+    points on a circle surrounding it. Extended radial gradients interpolate
+    colors between a focal circle and a center circle. Points outside the cone
+    defined by the two circles will be transparent. For simple radial gradients
+    the focal point is adjusted to lie inside the center circle, whereas the
+    focal point can have any position in an extended radial gradient.

+    Outside the end points the gradient is either padded, reflected or repeated
