Detailed Description

DatasetProxyModel takes a KChart dataset configuration and translates it into a filtering proxy model.

The resulting model will only contain the part of the model that is selected by the dataset, and the according row and column header data.

Currently, this model is implemented for table models only. The way it would work with models representing a tree is to be decided.

The column selection is configured by passing a dataset description vector to the model. This vector (of integers) is supposed to have one value for each column of the original model. If the value at position x is -1, column x of the original model is not included in the dataset. If it is between 0 and (columnCount() -1), it is the column the source column is mapped to in the resulting model. Any other value is an error.

bool DatasetProxyModel::setData ( const QModelIndex index,
const QVariant value,
int  role 
)
overridevirtual

Overloaded from base class.

Reimplemented from QSortFilterProxyModel.

Definition at line 218 of file KChartDatasetProxyModel.cpp.

void DatasetProxyModel::setDatasetColumnDescriptionVector ( const DatasetDescriptionVector columnConfig)
slot

Configure the dataset selection for the columns.

Every call to this method resets the previous dataset description.

Definition at line 54 of file KChartDatasetProxyModel.cpp.

void DatasetProxyModel::setDatasetDescriptionVectors ( const DatasetDescriptionVector rowConfig,
