Class WAggregateProxyModel

public class WAggregateProxyModel extends WAbstractProxyModel
A proxy model for JWt's item models that provides column aggregation.

This proxy model does not store data itself, but presents data from a source model, and presents methods to organize columns using aggregation, through which a user may navigate (usually to obtain more detailed results related to a single aggregate quantity).

To use this proxy model, you should provide a source model using setSourceModel(), and define column ranges that can be aggregated using addAggregate().

This example would render like this:

Note: This model does not support dynamic changes to the column definition of the source model (i.e. insertions or deletions of source model columns).
