1.TestFrame.java，用于绘制主面板的组件，以下是源码：

import java.awt.Dimension;  import java.awt.FlowLayout;  import java.awt.Font;  import java.awt.Insets;    import javax.swing.ImageIcon;  import javax.swing.JButton;  import javax.swing.JFrame;  import javax.swing.JMenuBar;  import javax.swing.JTextField;  import javax.swing.UIManager;  import javax.swing.plaf.basic.BasicButtonUI;    public class TestFrame extends JFrame {     private JTextField searchText = null;   private JButton searchBtn = null;   private JButton editBtn = null;   private JButton saveBtn = null;     public TestFrame() {    setLookAndFeel();    init();   }     /**    * 为主面板设置皮肤    */   private void setLookAndFeel() {    try {     UIManager       .setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");    } catch (Exception e) {     e.printStackTrace();    }   }     /**    * 增加工具栏的组件，并设置样式    */   private JMenuBar addMenuBar() {    JMenuBar menuBar = new JMenuBar();    menuBar.setLayout(new FlowLayout(40, 4, 0));    // 增加文件选择按钮    menuBar.add(createBtn("File", "./src/folder_up.png"));      // 增加编辑按钮    editBtn = createBtn("Edit", "./src/page_edit.png");    //editBtn.setEnabled(false);    menuBar.add(editBtn);      // 增加保存文件按钮    saveBtn = createBtn("Save", "./src/folder_down.png");    //saveBtn.setEnabled(false);    menuBar.add(saveBtn);      // 增加查询输入文本框    searchText = new JTextField();    searchText.setPreferredSize(new Dimension(140, 27));    menuBar.add(searchText);      // 增加查询按钮    searchBtn = createBtn("Search", "./src/search.png");    //searchBtn.setEnabled(false);    menuBar.add(searchBtn);      return menuBar;   }     /**    * 创建工具栏按钮    *     * @author lqj    * @param text    *            按钮名称    * @param icon    *            按钮图标所在路径    * @return 返回添加样式和监听器后的按钮    */   private JButton createBtn(String text, String icon) {    JButton btn = new JButton(text, new ImageIcon(icon));    btn.setUI(new BasicButtonUI());// 恢复基本视觉效果    btn.setPreferredSize(new Dimension(80, 27));// 设置按钮大小    btn.setContentAreaFilled(false);// 设置按钮透明    btn.setFont(new Font("粗体", Font.PLAIN, 15));// 按钮文本样式    btn.setMargin(new Insets(0, 0, 0, 0));// 按钮内容与边框距离    btn.addMouseListener(new MyMouseListener(this));    return btn;   }     /**    * @author lqj    * 初始化主面板和工作栏内容    */   private void init() {      JMenuBar menuBar = addMenuBar();    // menuBar.setBackground(Color.WHITE);    menuBar.setPreferredSize(new Dimension(1400, 30));    this.setJMenuBar(menuBar);    this.setSize(1320, 750);    this.setLocationRelativeTo(null);    this.setVisible(true);    this.setTitle("TestButton");    this.setDefaultCloseOperation(EXIT_ON_CLOSE);    // this.setBackground(Color.gray);   }     // main   public static void main(String[] args) {    new TestFrame();   }    }

    2.MyMouseListener.java，用于增加鼠标事件，源码如下：

import java.awt.Color;  import java.awt.event.MouseEvent;  import java.awt.event.MouseListener;    import javax.swing.JButton;  import javax.swing.border.Border;  import javax.swing.border.EtchedBorder;    public class MyMouseListener implements MouseListener {     private TestFrame frame;     public MyMouseListener() {    // TODO Auto-generated constructor stub   }     public MyMouseListener(TestFrame f) {    this.frame = f;   }     @Override   public void mouseClicked(MouseEvent e) {    // TODO Auto-generated method stub    String btnName =((JButton)e.getSource()).getText();    if ("File".equals(btnName.trim())) {     //鼠标点击事件    }   }     @Override   public void mousePressed(MouseEvent e) {    // TODO Auto-generated method stub    JButton btn = (JButton) e.getComponent();    Border etchedBorder = new EtchedBorder(EtchedBorder.RAISED);// 设置边框凸显    btn.setBorder(etchedBorder);   }     @Override   public void mouseReleased(MouseEvent e) {    // TODO Auto-generated method stub    JButton btn = (JButton) e.getComponent();    Border etchedBorder = new EtchedBorder(EtchedBorder.LOWERED);// 设置边框凹显    btn.setBorder(etchedBorder);   }     @Override   public void mouseEntered(MouseEvent e) {    // TODO Auto-generated method stub    JButton btn = (JButton) e.getComponent();    btn.setForeground(new Color(0x33, 0x66, 0xcc));// 设置字体颜色    btn.setBorderPainted(true);// 显示边框    Border etchedBorder = new EtchedBorder(EtchedBorder.LOWERED);// 设置边框凹显    btn.setBorder(etchedBorder);    btn.setRolloverEnabled(true);   }     @Override   public void mouseExited(MouseEvent e) {    // TODO Auto-generated method stub    JButton btn = (JButton) e.getComponent();    btn.setForeground(Color.black);// 设置字体颜色    btn.setBorderPainted(false);// 隐藏边框   }    }
