关于java swing的鼠标事件

package te;

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseListener;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JList;

import com.sun.glass.events.MouseEvent;

public class MainFrame extends JFrame {

private JPanel contentPane;

/**
 * Launch the application.
 */
public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                MainFrame frame = new MainFrame();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

/**
 * Create the frame.
 */
public MainFrame() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 450, 300);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    contentPane.setLayout(new BorderLayout(0, 0));
    setContentPane(contentPane);

    JList list = new JList();
    contentPane.add(list, BorderLayout.CENTER);
    list.addMouseListener(new MouseAdapter(){
        public void mouseClicked(MouseEvent e){
                 if(e.getClickCount==2) {}
        }
    });

}

}

比如如上建立JList，添加鼠标监听后，无法使用getclickcount()方法。而把JList单独拿出去新建个类就可以重写了。是不是因为跟MainFrame在一起所以没法重写mouseClicked方法？有没有办法在mainframe里用的？
