swing编程实现闪屏登录效果_综合

1、先写一个闪屏类

package com.mhl.Tools;
import java.awt.*;
import javax.swing.*;
//开发一个闪屏类 

public class paint extends JPanel implements Runnable

2、用户登陆窗口类

package com.mhl.View;
import java.awt.*;
import java.awt.event.*;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.*;


import com.mhl.Tools.*;
public class UserLogin extends JDialog implements ActionListener {
   

	/**
	 * @param args
	 */

	LoginBackImage bgimage=null; //背景图片
	paint p=null;  //闪屏

	 JLabel jb1,jb2,jb3;
	 JTextField juserName;
	 JPasswordField   jPwd;

	 JButton jconfirm,jcancel;

	public static void main(String[] args) {
   

		UserLogin login=new UserLogin();

	}

  public UserLogin()
	{
   
		jb1=new JLabel("请输入用户编号:");
		jb1.setFont(myFont.f1);
		//设置jb1在容器中的位置和大小,注意：只有在空布局中才使用此设置
	    jb1.setBounds(60, 190, 150, 30);
		this.add(jb1);


		juserName=new JTextField();
		juserName.setBounds(180,190,120,30);
		//设置下凹
		juserName.setBorder(BorderFactory.createLoweredBevelBorder());
		this.add(juserName);

		jb2=new JLabel("(或员工号)");
		jb2.setFont(myFont.f4);
		jb2.setForeground(Color.red);
		jb2.setBounds(100,210,100,30);
		this.add(jb2);

	    jb3=new JLabel("用户密码:");
	    jb3.setBounds(60,240,150,30);
	    jb3.setFont(myFont.f1);
	    this.add(jb3);

	    jPwd=new JPasswordField();
	    jPwd.setBounds(180,240,120,30);
		//设置边框下凹
	    jPwd.setBorder(BorderFactory.createLoweredBevelBorder());
	    this.add(jPwd);


	    jconfirm=new JButton("确定");
	    jconfirm.setBounds(105,300,75,30);
	    jconfirm.setFont(myFont.f1);
	    this.add(jconfirm);

	    jcancel=new JButton("取消");
	    jcancel.setBounds(215,300,75,30);
	    jcancel.setFont(myFont.f1);
	    jcancel.addActionListener(this);
	    this.add(jcancel);


	    //空布局
		this.setLayout(null);
		this.setSize(360,360);

		//加背景图片
		bgimage=new LoginBackImage();
		bgimage.setBounds(0, 0, 360, 360);
		this.add(bgimage);

		//加闪屏效果
		p=new paint();
		this.add(p);
	    //取掉边框修饰效果
		this.setUndecorated(true);
		//窗体居中
		this.setLocationRelativeTo(null);
		this.setVisible(true);


	}

@Override
public void actionPerformed(ActionEvent e) {
   

    if(e.getSource()==jconfirm)
    {
   
    	//todo
    }else if(e.getSource()==jcancel)
    {
   

    	System.exit(0);
    }
}
}
/*
 * 登陆截面的背景图片
 */
class LoginBackImage extends JPanel
{
   
	Image bg=null;
  	LoginBackImage()
	{
   
	  try {
   
		bg=ImageIO.read(new File("Images/login.gif"));
	} catch (IOException e) {
   

		e.printStackTrace();
	}

	}
  	public void paintComponent(Graphics g)
  	{
   
  		g.drawImage(bg, 0, 0,360,360,this);
  	}
}

3、实现闪屏登陆效果

package com.mhl.View;

import java.awt.*;
import javax.swing.*;


import com.mhl.Tools.*;
public class CataLog extends JWindow implements Runnable  {
   

	/**
	 * @param args
	 */

	paint p=null;
	public static void main(String[] args) {
   

		CataLog ct=new CataLog();
		Thread t=new Thread(ct);
		t.start();
	}


	public CataLog()
	{
   
		this.setSize(400,240);

		//加闪屏
		p=new paint();
		this.add(p);

		this.setLocationRelativeTo(null);
		this.setVisible(true);
	}


	@Override
	public void run() {
   

		while(true)
		{
   

			try {
   
				Thread.sleep(30*500); 
			} catch (InterruptedException e) {
   
				// TODO Auto-generated catch block
				e.printStackTrace();
			}

			//启动登陆窗口
			new UserLogin();
			this.dispose();
		}
	}

}

4、登陆窗口类中用到的类型

package com.mhl.Tools;
import java.awt.*;
public class myFont {
   

  public static Font f0=new Font("宋体",Font.PLAIN, 18);
  public static Font f1=new Font("宋体",Font.PLAIN, 16);
  public static Font f2=new Font("宋体",Font.PLAIN,15);
  public static Font f3=new Font("宋体",Font.PLAIN,14);
  public static Font f4=new Font("宋体",Font.PLAIN,13);
}
