Java.enableEvents.processXxxEvent(XxxEvent e)

被监视器，enableEvents()搞得死去活来的-_-！

 

干脆就乱炖一下！

 

//test.javapackage myprojects.Test;import java.awt.*;import java.awt.event.*;import java.awt.Frame;public class Test {public static void main(String[] args) {// TODO: Add your code herefinal MyFrame f=new MyFrame("MyFrame");MyButton btn=new MyButton("ok");btn.fx=f;f.btnx=btn;/*btn.addMouseListener(new MouseAdapter(){public void mouseClicked(MouseEvent e){f.dispose();} });*/btn.fx.add(f.btnx,"North");btn.fx.setSize(400,400);btn.fx.setVisible(true);}}

 

//MyFrame.javapackage myprojects.Test;import java.awt.Frame;import java.awt.event.*;import java.awt.*;import java.awt.Button;public class MyFrame extends Frame {MyButton btnx=null;public MyFrame(String title){super(title);enableEvents(AWTEvent.MOUSE_EVENT_MASK); //激活鼠标事件enableEvents(AWTEvent.WINDOW_EVENT_MASK); //激活窗口事件//enableEvents(AWTEvent.MOUSE_MOTION_EVENT_MASK); //激活鼠标移动事件}public void processMouseEvent(MouseEvent e){ //鼠标点击窗口时关闭程序if(e.getID()==MouseEvent.MOUSE_CLICKED){this.dispose();}}public void processWindowEvent(WindowEvent e){ //关闭窗口if(e.getID()==WindowEvent.WINDOW_CLOSING){dispose();}}/*public void processMouseMotionEvent(MouseEvent e){ //鼠标进入窗口时btnx隐藏btnx.setVisible(false);}*/}

 

如果在A类中访问B类方法中的变量，可以在A类中创建B类型的实例。

 

//MyButton.javapackage myprojects.Test;import java.awt.Button;import java.awt.event.*;import java.awt.*;public class MyButton extends Button {MyFrame fx=null;public MyButton(String title){super(title);enableEvents(AWTEvent.MOUSE_EVENT_MASK);}/*protected void processMouseEvent(MouseEvent e){if(e.getID()==MouseEvent.MOUSE_ENTERED){setVisible(false);}if(e.getID()==MouseEvent.MOUSE_EXITED){setVisible(true);}}*/protected void processMouseEvent(MouseEvent e){if(e.getID()==MouseEvent.MOUSE_CLICKED){fx.dispose();}}}

 

好像明白了点点，不过脑袋还是粘糊糊的感觉~~
