java窗口編程問題

我給妳寫了個小例子：

import javax.swing.JButton;

import javax.swing.JOptionPane;

import javax.swing.JPanel;

import javax.swing.JTabbedPane;

import javax.swing.JTextField;

public class TabDialog {

public TabDialog() {

JTabbedPane jtab = new JTabbedPane();

JPanel tab1 = new JPanel();

for (int i = 0; i < 4; i++) {

tab1.add(new JButton("JButton"));

}

JPanel tab2 = new JPanel();

for (int i = 0; i < 4; i++) {

tab2.add(new JTextField("JTextField"));

}

jtab.addTab("tab1", tab1);

jtab.addTab("tab2", tab2);

JOptionPane.showOptionDialog(null, jtab, "dialog",

JOptionPane.YES_NO_OPTION, JOptionPane.INFORMATION_MESSAGE,

null, null, null);

}

public static void main(String[] args) {

new TabDialog();

}

}

謝謝采納！！！
