以下示例展示如何在基于swing的应用程序中显示带有自定义按钮文本的确认对话框。
使用以下API -
JOptionPane- 创建标准对话框。JOptionPane.showOptionDialog()- 显示带有多个选项的消息警告。JOptionPane.YES_NO_OPTION- 获得是和否按钮。
示例
package com.yiibai.swingdemo;
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.LayoutManager;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class SwingTester {
public static void main(String[] args) {
createWindow();
}
private static void createWindow() {
JFrame frame = new JFrame("Swing Tester");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
createUI(frame);
frame.setSize(560, 200);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
private static void createUI(final JFrame frame){
JPanel panel = new JPanel();
LayoutManager layout = new FlowLayout();
panel.setLayout(layout);
JButton button = new JButton("点击我");
final JLabel label = new JLabel();
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
String[] options = {"是的，马上走起!", "不是，等一下！"};
int result = JOptionPane.showOptionDialog(
frame,
"确定要退出？",
"Swing是/否提示信息~",
JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE,
null, //no custom icon
options, //button titles
options[0] //default button
);
if(result == JOptionPane.YES_OPTION){
label.setText("选择：是");
}else if (result == JOptionPane.NO_OPTION){
label.setText("选择：否");
}else {
label.setText("未选择~");
}
}
});
panel.add(button);
panel.add(label);
frame.getContentPane().add(panel, BorderLayout.CENTER);
}
}
