30 \class QPieModelMapper
31 \brief part of QtCommercial chart API.
32 \mainclass
33
34 Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
35 The instance of this class cannot be created directly. QHPieModelMapper of QVPieModelMapper should be used instead. This class is used to create a connection between QPieSeries and QAbstractItemModel derived model object.
36 It is possible to use both QAbstractItemModel and QPieSeries model API. QPieModelMapper makes sure that Pie and the model are kept in sync.
37 NOTE: used model has to support adding/removing rows/columns and modifying the data of the cells.
