title: setSize not influencing size of button
body: <p>I have a sample code :</p>
  
  <pre><code>import java.awt.*;
  import javax.swing.*;
  import javax.swing.border.BevelBorder;
  
  public class AWT extends JFrame {
  
      public static void main(String[] args) {
          final JFrame frame = new JFrame();
          frame.setPreferredSize(new Dimension(600, 450));
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setBackground(Color.green.darker());
  
          Button btn_1 = new Button("Button 1");
          btn_1.setBackground(Color.green.darker());
          btn_1.setSize(40, 100);
          Button btn_2 = new Button("Button 2");
          btn_2.setBackground(Color.green.darker());
          btn_2.setSize(40, 100);
          Button btn_3 = new Button("Button 3");
          btn_3.setBackground(Color.green.darker());
          btn_3.setSize(40, 100);
  
          JPanel players = new JPanel(new GridLayout(1, 3));
          players.add(btn_1);
          players.add(btn_2);
          players.add(btn_3);
          players.setBackground(Color.green.darker());
          players.setPreferredSize(new Dimension(450, 80));
  
          JPanel game = new JPanel();
          game.setBorder(BorderFactory.createBevelBorder(BevelBorder.LOWERED));
          game.setBackground(Color.green);
          game.setPreferredSize(new Dimension(600, 370));
  
          JPanel content = new JPanel();
          content.setLayout(new BorderLayout());
          frame.setContentPane(content);
          content.add(players, BorderLayout.NORTH);
          content.add(game, BorderLayout.SOUTH);
          frame.pack();
   frame.setVisible(true);
      }
  }
