Swing的BorderLayout示例

BorderLayout類排列組件為五個區域：東，西，北，南和中心。

示例

import java.awt.BorderLayout;

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 BorderLayout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();
      BorderLayout layout = new BorderLayout();
      layout.setHgap(10);
      layout.setVgap(10);

      panel.setLayout(layout);
      panel.add(new JButton("中心"),BorderLayout.CENTER);
      panel.add(new JButton("行開始"),BorderLayout.LINE_START);
      panel.add(new JButton("行結束"),BorderLayout.LINE_END);
      panel.add(new JButton("東"),BorderLayout.EAST);
      panel.add(new JButton("西"),BorderLayout.WEST);
      panel.add(new JButton("北"),BorderLayout.NORTH);
      panel.add(new JButton("南"),BorderLayout.SOUTH);
      frame.getContentPane().add(panel, BorderLayout.CENTER);
   }
}
