Listener分很多种:ActionListener,MouseListener,PopMenuListener,windowListener等等。 二、监听事件实现方式 1. 直接在控件中添加监听 如:给“保存按钮”添加ActionListener监听 1 saveCharaEditButton.addActionListener(new ActionListener() { 2 3 @Override ...
The class that is interested in processing a mouse wheel event implements this interface (and all the methods it contains). The listener object created from that class is then registered with a component using the component'saddMouseWheelListenermethod. A mouse wheel event is generated when the mo...
