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 ActionListener{
	MyImageButton myButton;
	Image	trying;
	Toolkit toolkit;
	Test(){
		setBounds(0,0,100,100);
		try{
			trying =(toolkit.getDefaultToolkit()).getImage("try.GIF");
		} catch(NullPointerException e){} 
		
		myButton=new MyImageButton(trying,"ok");
		myButton.addActionListener(this);
		add(myButton);
		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 actionPerformed(ActionEvent e) {
		
		if (myButton==e.getSource()) { 
			System.out.println("this button is clicked");
		}
	
    }

}
