import java.awt.event.*;

public class JComboBoxMouseListenerExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("JComboBox MouseListener Example");

        // 创建下拉列表框并设置可选项
        String[] options = {"Option 1", "Option 2", "Option 3"};
        JComboBox<String> comboBox = new JComboBox<>(options);

        // 创建MouseListener并添加到jComboBox
        comboBox.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                // 在鼠标单击事件中执行特定的操作
                System.out.println("Mouse clicked on JComboBox");
            }
        });

        frame.add(comboBox);
