All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

public class DDataLov

extends javax.swing.JComponent

Lov para escolha por lista de valores.
Equivalente a comboBox so que abre uma Dialog independente e permite eventuais query(s) sobre a tabela
Os dados sao os que ficam preenchidos num DDataControl da pool de DDataControl, no entanto , embora seja possivel uma filtragem da informacao do DDataControl, deve tambem poder efectuar query(s) sobre a base de dados (se estiver connectado)
Esta classe vai ser substituida por uma mais bem arquitectada
