\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.
