jscrollbartest.java

java经典的源代码 我非常喜欢这个源代码 对于编程很有好处

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class JScrollBarTest extends JFrame {
  JScrollBar scroll1,scroll2;
   public JScrollBarTest (){
     super("A toolTip test");
     Container contentPane = getContentPane();
     contentPane.setLayout(new GridLayout(2,1));
     scroll1=new JScrollBar(JScrollBar.VERTICAL,0,10,0,200);
     contentPane.add(scroll1,BorderLayout.EAST);
     scroll2=new JScrollBar(JScrollBar.HORIZONTAL,0,10,0,100);
     contentPane.add(scroll2,BorderLayout.SOUTH);
     setSize( 200, 200 );
     setVisible( true );
   }
   public static void main( String args[] ){
     JScrollBarTest app = new JScrollBarTest ();
     app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
   }
}
