import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class SwingTester {
   public static void main(String[] args) {
      createWindow();
   }

   private static void createWindow() {    
      JFrame frame = new JFrame("Swing的GridLayout示例");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      createUI(frame);
      frame.setSize(560, 200);      
      frame.setLocationRelativeTo(null);  
      frame.setVisible(true);
   }

   private static void createUI(final JFrame frame){  
      JPanel panel = new JPanel();
      GridLayout layout = new GridLayout(0,3);
      layout.setHgap(10);
      layout.setVgap(10);

      panel.setLayout(layout);        
      panel.add(new JButton("按钮 1"));
      panel.add(new JButton("按钮 2")); 
      panel.add(new JButton("按钮 3")); 
      panel.add(new JButton("按钮 4")); 
      panel.add(new JButton("按钮 5"));    
      frame.getContentPane().add(panel, BorderLayout.CENTER);
