我是用jbuilder做的SWING，用JTABLE的abstrctmodel方式实现JTABLE的。我现在想做到的是，在查询出来的结果中，用户先点JTABLE的某条记录，然后点一个“删除"的按钮，之后将其删除，
我看书上用到的是selectionmodel，想在JB中用，但遇到这样的问题，因为JB的代码是这样生成的
public class Query
extends JInternalFrame {
}
class Query_jButton2_actionAdapter
implements ActionListener{
private Query adaptee;
Query_jButton2_actionAdapter(Query adaptee) {
this.adaptee = adaptee;
} public void actionPerformed(ActionEvent e) {
adaptee.jButton2_actionPerformed(e);
}
这样的，
那么，我要必须implments ListSelectionListener,这句话加在哪里？

只是实现了删除功能，但没有更新数据到数据库，如果要更新到数据，
请LZ自己加代码...
