Interface ContainerData

All Superinterfaces:
FieldData
All Known Subinterfaces:
FormData
public interface ContainerData extends FieldData
Expõe para as classes controller as operações disponíveis em um container (data view) do NXJ.

Essa interface é implementada pela classe forms.systextil.ControleJavaDataView no NXJ, e, teoricamente, uma classe java que implemente essa interface é capaz de controlar qualquer DataView no NXJ.
