事件触发问题，为什么触发不了mouseMoved

Question

键盘事件可以触发，但鼠标移动事件触发不了？？？就是进不了mouseMoved，为什么？？？
我用相同的方法作了个小例子，没问题，但一拥到这里就进不去。头痛。请大侠帮忙。import java.awt.Frame;import javax.swing.*;

    }}

Answer 1

public KVM_mouseMotionAdapter(KVMFullScreen adaptee) {
            this.adaptee = adaptee;
        }

Answer 2

if (e.getY() < 120) {
          adaptee.getContentPane().removeAll();
          toolbar=new KVMToolBar(adaptee.getInternalFrame());
          adaptee.getContentPane().add(toolbar,BorderLayout.NORTH);
      }
这段程序错！
换成System.out.println("haha");
