Java MouseListener for ComboBox

问题

How do I add a MouseListener to a ComboBox? I have tried:

comboBox.addMouseListener(new MouseAdapter() { 
    public void mousePressed(MouseEvent event) {
        System.out.println("ok");   
    }

    public void mouseReleased(MouseEvent event) {
        System.out.println("ok");   
    }
});

It doesn't seems to work. I need to make the program do something when I press on the ComboBox, for example for typing because it is editable.

For basic swing related questions (I assume you use swing here), check the swing trail of the Java tutorial.
