+ \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.
