89 \brief The QIdentityProxyModel class proxies its source model unmodified -

90 -

91 \ingroup model-view -

92 -

93 QIdentityProxyModel can be used to forward the structure of a source model exactly, with no sorting, filtering or other transformation. -

94 This is similar in concept to an identity matrix where A.I = A. -

95 -

96 Because it does no sorting or filtering, this class is most suitable to proxy models which transform the data() of the source model. -

97 For example, a proxy model could be created to define the font used, or the background colour, or the tooltip etc. This removes the -

98 need to implement all data handling in the same class that creates the structure of the model, and can also be used to create -

99 re-usable components. -

100 -

101 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. -
