tooltipdemo.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 toolTipDemo extends JFrame {
  private JButton b1,b2;
   public toolTipDemo (){
     super("A toolTip test");
     b1=new JButton("Button1");
     b2=new JButton("Button2");
     b1.setToolTipText("This is button 1");
     b2.setToolTipText("This is button 2");
     Container contentPane = getContentPane();
     contentPane.setLayout(new FlowLayout());
     contentPane.add(b1);
     contentPane.add( b2);
     setSize( 200, 80 );
     setVisible( true );
   }
   public static void main( String args[] ){
     toolTipDemo app = new toolTipDemo();
     app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
   }
}
