MouseListener 接口

MouseEvent類的對象應該實現(xiàn)這個接口。組件注冊。使用addMouseListener（）方法，該對象可以被注冊。

接口聲明

以下是聲明的java.awt.event.MouseListener接口：

public interface MouseListener
   extends EventListener

接口中的方法

繼承的方法

這個接口繼承的方法從下面的接口：

• java.awt.EventListener

MouseListener的示例

選擇使用任何編輯器創(chuàng)建以下java程序D:/ > AWT > com > yiibai > gui >

         public void windowClosing(WindowEvent windowEvent){

      panel.setLayout(new FlowLayout());        
      panel.addMouseListener(new CustomMouseListener());

      Label msglabel = new Label();

      panel.add(msglabel);

      controlPanel.add(panel);

      mainFrame.setVisible(true);  
   }
