eu.webtoolkit.jwt.WReadOnlyProxyModel

public class WReadOnlyProxyModel
extends WAbstractProxyModel

A read-only wrapper for a source model.

This is a simple proxy model which provides a read-only view on a source model. This is convenient for situations where you want to share a common read-only source model between different sessions.
