public class Boxtest implements ActionListener{

public Boxtest() {
static int n;
static String[] items ={"one","two","three","four","five"};
JFrame f = new JFrame();
JComboBox combo=new JComboBox(items));
JButton buttonok=new JButton("Button ok"));

Container contentPane = f.getContentPane();
Box baseBox = Box.createHorizontalBox();
contentPane.add(baseBox);
baseBox.add(combo);
baseBox.add(buttonok);

f.setTitle("Boxtest");
f.setSize(new Dimension(200,200));
f.setVisible(true);

f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});

public void actionPerformed(ActionEvent e) {
if(e.getSource()==buttonOK){
n = combo.getSelectedIndex();
f.setVisible(false);
}
}

//返回选中的项目的值
public static String getItems(){
....??如何实现?
}

}


我想通过内部函数public static String getItems()取得选择的项目值,该如何实现呢?

JComboBox中的Object getSelectedItem()可以直接得到被选择的对象!

问题是，
public static String getItems(){
n = combo.getSelectedIndex();
return items[n];
}
这样得到的只是第一次没有选择过时的项目值
如果想在按下确定按钮后，返回当前选定的项目，该怎么办呢？

JList.addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
Object value = list.getSelectedItem();
}
});
