test.java

电脑编程技巧和源码。很不错的。

import java.awt.*;
import java.awt.event.*;

public class Test extends Frame implements SpeedListener{
	Speedbar speedbar;
	
	Test(){
		setBounds(0,0,200,100);
		
		speedbar=new Speedbar();
		speedbar.addSpeedListener(this);
		add(speedbar);
		enableEvents(AWTEvent.WINDOW_EVENT_MASK );
	}
	public void processWindowEvent(WindowEvent e){
		switch(e.getID()){
			case WindowEvent.WINDOW_CLOSING:
				dispose();
		}
	}
	public static void main(String argv[]){
		(new Test()).setVisible(true);
	}
	
	public void getSpeedValue(int value){
		System.out.println("the relevant value is"+value);
	
    }

}
