Question

Java swing中的JList组件怎么获得所选项的字符串？？？

Answer 1

//用Model来做吧,下面的例子你点一下,就会加一个
import javax.swing.*;
import java.awt.event.*;
public class TT {
static int i=0;
public static void main(String[] args) {
final DefaultListModel m=new DefaultListModel();
JList l = new JList(m);
m.addElement("请随便点击..");
l.addMouseListener(new MouseAdapter(){
public void mousePressed(MouseEvent e)
});
JDialog d = new JDialog();
d.setSize(100,300);
d.add(l);
d.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
d.setVisible(true); }}
