Detailed Description

A proxy model used for decorating data with attributes.

An AttributesModel forwards data from and to the source model and adds attributes, data that influences the graphical rendering of the source model data. The attributes are distinguished from the source model's data by their role values. Therefore this class does not need to, and does not, change the data layout from the source model's; indexes that refer to the same data have the same row and column values in both models. Attribute changes, that is changes to data with the attribute role, via the interface of this class (including setData()) are stored internally and not forwarded to the source model.

) const

Returns the data that were specified at per column level, or the globally set data, or the default data, or QVariant().

Definition at line 311 of file KChartAttributesModel.cpp.

QVariant AttributesModel::data ( const QModelIndex index,
int  role = Qt::DisplayRole 
) const
