manullayout.java

这一些程序都是实验之用

import java.awt.*;
public class ManulLayout extends  Thread{
	public static void main(String args[])throws Exception{
		Frame f=new Frame("Hello");
		f.setLayout(null);
		f.setSize(300,400);
		Button b=new Button("press me");
		b.setSize(150,30);
		for(int i=0;i<100;i++)
			{		
					Thread.sleep(60);
					
					if((b.getAlignmentX()+b.WIDTH)<(f.getAlignmentX()))
					b.setLocation(30+i*5,60+i);
					
					else
			 		  b.setLocation(300-i*2,400-i*2);
			 		
			 		f.add(b);
					f.setVisible(true);
			}
	
	}
}
