需求说明:

使用Swing布局管理器和常用控件,实现仿QQ登录界面 

实现思路:

创建登录界面的类QQLogin,该类继承父类JFrame,在该类中创建无参数的构造方法,在构造方法中,设置窗体大小为宽355、高265,窗体的布局格式为绝对定位,通过this.setResizable(false)方法设置窗体大小不能改变。

创建初始化方法,在该方法中,创建图10.12中的相关组件,并在该方法中合理设置各组件之间的位置。在构造方法中调用该初始化方法。

实现代码:

package com.tencent.qq;

import javax.swing.JFrame;

import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JComboBox;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;

public class QQLogin extends JFrame {
	public QQLogin() {
		this.setBounds(700, 300, 600, 454);
		this.setTitle("QQ登录界面");
		this.setLayout(null);
		this.setResizable(false);
		
		Icon icon1 = new ImageIcon("img/logo.jpg");
		JLabel img1 = new JLabel(icon1);
		img1.setBounds(0, 0, 600, 154);
		
		Icon icon2 = new ImageIcon("img/icon.jpg");
		JLabel img2 = new JLabel(icon2);
		img2.setBounds(80, 170, 110, 100);
		
		JTextField userTest = new JTextField();
		userTest.setBounds(200, 185, 250, 30);
		JPasswordField pawTest = new JPasswordField();
		pawTest.setBounds(200, 230, 250, 30);
		
		JLabel zczh = new JLabel("注册账号");
		zczh.setBounds(460, 100, 200, 200);
		JLabel zhmm = new JLabel("找回密码");
		zhmm.setBounds(460, 145, 200, 200);
		
		JComboBox ComboBox = new JComboBox();
		ComboBox.addItem("在线");
		ComboBox.addItem("离开");
		ComboBox.addItem("忙碌");
		ComboBox.addItem("隐身");
		ComboBox.setBounds(95, 280, 85, 25);
		
		JCheckBox jzmm = new JCheckBox("记住密码");
		jzmm.setBounds(220, 270, 100, 50);
		JCheckBox zddl = new JCheckBox("自动登录");
		zddl.setBounds(350, 270, 100, 50);
		
		JButton dzh = new JButton("多账号");
		dzh.setBounds(50, 340, 105, 30);
		JButton sz = new JButton("设置");
		sz.setBounds(180, 340, 105, 30);
		JButton dl = new JButton("登录");
		dl.setBounds(420, 340, 105, 30);

		this.add(img1);
		this.add(img2);
		this.add(userTest); 
		this.add(pawTest);
		this.add(zczh);
		this.add(zhmm);
		this.add(ComboBox);
		this.add(jzmm);
		this.add(zddl);
		this.add(dzh);
		this.add(sz);
		this.add(dl);
		
	}

	public static void main(String[] args) {
		QQLogin login = new QQLogin();
		login.setVisible(true);
	}
}
