Java图形化编程美化

1.去掉原来的界面的装饰，改用自己装饰：

先看看效果，如下图

 

如何实现：

1.去掉原来的windows的装饰：

this.setSize(340, 256);

this.setUndecorated(true);

//虽然去掉了装饰，但是下面的界面图标与界面的标题是不可以去掉的，否则在桌面最下面的工具栏中会看不到标题与图标的。

URL url5 = this.getClass().getResource("/p_w_picpath/client_title.png");

this.setIconImage(new ImageIcon(url5).getImage());

this.setTitle("用户登录");

this.setLocation(new ScreenLocation(348,250).getLocation());

this.setVisible(true);

this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);

this.setResizable(false);

2.移动界面的代码：

Point loc = null;

Point tmp = null;

boolean isDragged = false;

//拖动窗体的方法

private void setDragable() {

this.addMouseListener(new java.awt.event.MouseAdapter() {

public void mouseReleased(java.awt.event.MouseEvent e) {

isDragged = false;

//当鼠标不拖动时，设置鼠标显示的样式

setCursor(new Cursor(Cursor.DEFAULT_CURSOR));

}

public void mousePressed(java.awt.event.MouseEvent e) {

tmp = new Point(e.getX(), e.getY());

isDragged = true;

//当鼠标点击时，鼠标显示的样式

setCursor(new Cursor(Cursor.DEFAULT_CURSOR));

}

});

//添加鼠标运动监听器

this.addMouseMotionListener(new java.awt.event.MouseMotionAdapter() {

public void mouseDragged(java.awt.event.MouseEvent e) {

if (isDragged) {

//重新设置界面的位置

loc = new Point(getLocation().x + e.getX() - tmp.x,

getLocation().y + e.getY() - tmp.y);

setLocation(loc);

}

}

});

}

3.添加界面最下化与关闭按钮：

//处理关闭窗口按钮

//com为界面的容器,exit为按钮JButton

com.add(exit);

exit.setBounds(300, 1, 37, 20);

exit.setBorder(null);

exit.setIcon(new ImageIcon(this.getClass().getResource("/p_w_picpath/login_exit.jpg")));

exit.addMouseListener(new MouseAdapter() {

public void mouseEntered(MouseEvent e) {

exit.setIcon(new ImageIcon(this.getClass().getResource("/p_w_picpath/login_exit2.jpg")));

}

public void mouseExited(MouseEvent e) {

exit.setIcon(new ImageIcon(this.getClass().getResource("/p_w_picpath/login_exit.jpg")));

}

public void mouseClicked(MouseEvent e) {

if(e.getClickCount() == 1){

System.exit(0);

}

}

});

//处理最小化窗口按钮

//com为界面的容器,minux为按钮JButton

com.add(minux);

minux.setBounds(272,1, 29, 20);

minux.setBorder(null);

minux.setIcon(new ImageIcon(this.getClass().getResource("/p_w_picpath/login_minux.jpg")));

minux.addMouseListener(new MouseAdapter() {

public void mouseEntered(MouseEvent e) {

minux.setIcon(new ImageIcon(this.getClass().getResource("/p_w_picpath/login_minux2.jpg")));

}

public void mouseExited(MouseEvent e) {

minux.setIcon(new ImageIcon(this.getClass().getResource("/p_w_picpath/login_minux.jpg")));

}

public void mouseClicked(MouseEvent e) {

if(e.getClickCount() == 1){

//从界面管理容器中取得主界面，然后最小化

FaceManager.getFace("login").setExtendedState(JFrame.ICONIFIED);

}

}

});

4.要实现界面为一张图片，主界面的布局要设置为null，然后用一个JLabel来放置背景图片。

URL url1 = this.getClass().getResource("/p_w_picpath/login.jpg");

background = new JLabel(new ImageIcon(url1));

Container com = this.getContentPane();

com.setLayout(null);

com.add(background);

background.setBounds(0, 0, 340, 256);

//下面是添加可以移动的方法

setDragable();

全部代码如下

public class ClientLogin extends JFrame implements ActionListener {
    private static final long serialVersionUID = 1L;

    public static String serverIp = "127.0.0.1";


    JLabel background,jl_uname,jl_psd,jl_ip;
    JPanel con,control;
    JTextField username,ipaddr;
    JPasswordField password;
    JButton jb_login,jb_cannel,jb_regist;


    JButton exit = new JButton();
    JButton minux = new JButton();

    Point loc = null;
    Point tmp = null;
    boolean isDragged = false;

    //拖动窗体的方法
    private void setDragable() {
        this.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseReleased(java.awt.event.MouseEvent e) {
                isDragged = false;
                setCursor(new Cursor(Cursor.DEFAULT_CURSOR));
            }
            public void mousePressed(java.awt.event.MouseEvent e) {
                tmp = new Point(e.getX(), e.getY());
                isDragged = true;
                setCursor(new Cursor(Cursor.DEFAULT_CURSOR));
            }
        });
        this.addMouseMotionListener(new java.awt.event.MouseMotionAdapter() {
            public void mouseDragged(java.awt.event.MouseEvent e) {
                if (isDragged) {
                    loc = new Point(getLocation().x + e.getX() - tmp.x,
                            getLocation().y + e.getY() - tmp.y);
                    setLocation(loc);
                }
            }
        });
    }

    //构造函数
    public ClientLogin() {
        FaceManager.addFace("login", this);
        URL url1 = this.getClass().getResource("/p_w_picpath/login.jpg");
        background = new JLabel(new ImageIcon(url1));
        con = new JPanel(null);
        jl_uname = new JLabel("用户名:",JLabel.CENTER);
        jl_psd = new JLabel("密码:",JLabel.CENTER);
        username = new JTextField();
        password = new JPasswordField();
        jl_ip = new JLabel("服务IP:");
        ipaddr = new JTextField(serverIp);
        con.add(jl_uname);
        con.add(username);
        con.add(jl_psd);
        con.add(password);
        con.add(jl_ip);
        con.add(ipaddr);
        control = new JPanel();

        //处理南部
        URL url2 = this.getClass().getResource("/p_w_picpath/denglu.gif");
        jb_login = new JButton(new ImageIcon(url2));
        jb_login.addActionListener(this);
        URL url3 = this.getClass().getResource("/p_w_picpath/quxiao.gif");
        jb_cannel = new JButton(new ImageIcon(url3));
        jb_cannel.addActionListener(this);
        URL url4 = this.getClass().getResource("/p_w_picpath/xiangdao.gif");
        jb_regist = new JButton(new ImageIcon(url4));

        //control.setBackground(Color.pink);

        Container com = this.getContentPane();
        com.setLayout(null);
        com.add(jl_uname);
