如何快速掌握Java GUI设计
使用java的GUI设计一个简单的登陆界面（1）
实现效果如下：
源代码：
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
public class Login{
private JFrame frame = new JFrame(“登录”);
private Container c = frame.getContentPane();
private JTextField username = new JTextField();
private JPasswordField password = new JPasswordField();
private JButton ok = new JButton(“确定”);
private JButton cancel = new JButton(“取消”);
public Login(){
frame.setSize(300,200);
c.setLayout(new BorderLayout());
initFrame();
frame.setVisible(true);
}
private void initFrame(){
//顶部
JPanel titlePanel = new JPanel();
titlePanel.setLayout(new FlowLayout());
titlePanel.add(new JLabel(“系统管理员登录”));
c.add(titlePanel,”North”);
//中部表单
JPanel fieldPanel = new JPanel();
fieldPanel.setLayout(null);
JLabel a1 = new JLabel(“用户名:”);
a1.setBounds(50,20,50,20);
JLabel a2 = new JLabel(“密 码:”);
a2.setBounds(50,60,50,20);
fieldPanel.add(a1);
fieldPanel.add(a2);
username.setBounds(110,20,120,20);
password.setBounds(110,60,120,20);
fieldPanel.add(username);
fieldPanel.add(password);
c.add(fieldPanel,”Center”);
//底部按钮
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new FlowLayout());
buttonPanel.add(ok);
buttonPanel.add(cancel);
c.add(buttonPanel,”South”);
}
public static void main(String[] args){
new Login();
}
}
给个java GUI 基础教程吧
package com.ambow.sky;
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TestBorderLayout extends JFrame {
JPanel jp;
JButton jb1,jb2,jb3,jb4,jb5;
public TestBorderLayout() {
this.setSize(300, 300);
jp = new JPanel();
jp.setLayout(new BorderLayout());
jb1 = new JButton(“东部”);
jb2 = new JButton(“西部”);
jb3 = new JButton(“南部”);
jb4 = new JButton(“北部”);
jb5 = new JButton(“中部”);
jp.add(jb1, BorderLayout.EAST);
jp.add(jb2, BorderLayout.WEST);
jp.add(jb3, BorderLayout.SOUTH);
jp.add(jb4, BorderLayout.NORTH);
jp.add(jb5, BorderLayout.CENTER);
this.add(jp);
this.setVisible(true);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
new TestBorderLayout();
}
}
这是一个布局的GUI，你可以运行看一下！
java中的GUI
其实你也不用严格的按着几步来做：
1，导入包也就是
import java.awt.*;
import java.awt.event.*;
或者import javax.swing.*;
import javax.swing.event.*;
2,构造，估计就是构造方法，就是初始化你的组件，
3，不知道
4，应该是给组件加监视器
5，实现接口的方法，也就是当你按了按钮或选择了菜单项会发生的动作
