如何用GridBagLayout填充BOTH和CENTER面板？

夥計！我怎樣才能正確放置椅子？在下面的圖片的第二幀中，我張貼了我想要放置這些對象的圈子。如何用GridBagLayout填充BOTH和CENTER面板？

我已經使用了4個BorderLayouts放置標籤和圖像，以便不給GridBagLayout的過於複雜，然後我將它們添加到GridBagLayout的是這樣的：

c.fill = GridBagConstraints.BOTH/*PAGE_START*/; 
    c.weightx = 10; 
    c.weighty = 10; 
    c.gridx = 1; 
    c.gridy = 0; 
    panel.add(topPlayerPanel, c); 

    c.gridx = 0; 
    c.gridy = 1; 
    panel.add(leftPlayerPanel, c); 

    c.gridx = 1; 
    c.gridy = 1; 
    panel.add(t, c); 

    c.gridx = 2; 
    c.gridy = 1; 
    panel.add(rightPlayerPanel, c); 

    c.gridx = 1; 
    c.gridy = 2; 
    panel.add(bottomPlayerPanel, c);

如果我把他們帶PAGE_START，LINE_START，LINE_END，PAGE_END，展示位置是正確的。不過，這並不表明我的整體形象:(

您可以使用佔用多餘的空間GridBagLayout看不見的組件和「推」的其他組件周圍。我用Box.Filler那些計算機圖標推到錶板。

import java.awt.BorderLayout; 
import java.awt.Color; 
import java.awt.Dimension; 
import java.awt.GridBagConstraints; 
import java.awt.GridBagLayout;

public class GBLTableWithChairs extends JFrame { 

    public GBLTableWithChairs() { 
     setTitle("Table with chairs"); 
     setDefaultCloseOperation(EXIT_ON_CLOSE); 
     setLayout(new GridBagLayout()); 

     GridBagConstraints gbc; 
     Box.Filler filler; 
     JLabel label; 

     JPanel table = new JPanel(new BorderLayout()); 
     table.setBorder(BorderFactory.createMatteBorder(1, 1, 1, 1, Color.GRAY)); 
     table.add(new JLabel("<html>TABLE&nbsp;TABLE<br/>TABLE&nbsp;TABLE<br/>TABLE&nbsp;TABLE")); 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 1; 
     gbc.gridy = 1; 
     add(table, gbc); // to frame 

     JPanel leftChair = new JPanel(new GridBagLayout()); 
     filler = createHorizontalFiller(); 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 0; 
     gbc.gridy = 0; 
     gbc.fill = GridBagConstraints.HORIZONTAL; 
     gbc.weightx = 1.0d; 
     leftChair.add(filler, gbc); // to leftChair 
     label = new JLabel(UIManager.getIcon("FileView.computerIcon")); 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 1; 
     gbc.gridy = 0; 
     leftChair.add(label, gbc); // to leftChair 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 0; 
     gbc.gridy = 1;

     JPanel topChair = new JPanel(new GridBagLayout()); 
     filler = createVerticalFiller(); 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 0;

     gbc.gridx = 0; 
     gbc.gridy = 1; 
     topChair.add(label, gbc); // to topChair 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 1; 
     gbc.gridy = 0; 
     add(topChair, gbc); // to frame 

     JPanel rightChair = new JPanel(new GridBagLayout()); 
     filler = createHorizontalFiller(); 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 1; 
     gbc.gridy = 0;

     gbc.weightx = 1.0d; 
     rightChair.add(filler, gbc); // to rightChair

     gbc = new GridBagConstraints(); 
     gbc.gridx = 2; 
     gbc.gridy = 1; 
     add(rightChair, gbc); // to frame 

     JPanel bottomChair = new JPanel(new GridBagLayout()); 
     filler = createVerticalFiller(); 
     gbc = new GridBagConstraints(); 
     gbc.gridx = 0; 
     gbc.gridy = 1; 
     gbc.fill = GridBagConstraints.VERTICAL; 
     gbc.weighty = 1.0d; 
     bottomChair.add(filler, gbc); // to bottomChair

     add(bottomChair, gbc); // to frame 

     setSize(200, 200); 
     setLocationRelativeTo(null); 
    } 

    private Box.Filler createHorizontalFiller() { 
     return new Box.Filler(new Dimension(0, 0), new Dimension(0, 0), new Dimension(32767, 0)); 
    } 

    private Box.Filler createVerticalFiller() { 
     return new Box.Filler(new Dimension(0, 0), new Dimension(0, 0), new Dimension(0, 32767)); 
    } 

    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Runnable() { 
      @Override 
      public void run() { 
       new GBLTableWithChairs().setVisible(true); 
      } 
     }); 
    } 

}

這應該讓你開始

非常感謝，真的！但我還有一個問題......我在下面添加了更多細節 – libburst

非常感謝我使用的填料rewrited我的代碼，但我有這個問題：！

例如爲左椅子，我放置填料，然後將leftChairPanel（用BorderLayout.NORTH一個JLabel一個BorderLayout的它conists，並在BorderLayout.CENTER圖像），但我得到這...也許我使用了錯誤的GridBagConstraints填充？

JPanel table = new JPanel(new BorderLayout()); 
    table.add(t); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 1; 
    gbc.gridy = 1; 
    panel.add(table, gbc); 

    JPanel leftChair = new JPanel(new GridBagLayout()); 
    filler = createHorizontalFiller(); 
    gbc.gridx = 0; 
    gbc.gridy = 0; 
    gbc.fill = GridBagConstraints.VERTICAL; 
    gbc.weightx = 1.0d; 
    leftChair.add(filler, gbc); //alla sedia di sinistra 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 1; 
    gbc.gridy = 0; 
    leftChair.add(leftPlayerPanel, gbc); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 0; 
    gbc.gridy = 1; 
    panel.add(leftChair, gbc); //al mainPanel 

    JPanel topChair = new JPanel(new GridBagLayout()); 
    filler = createVerticalFiller(); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 0; 
    gbc.gridy = 0; 
    gbc.fill = GridBagConstraints.VERTICAL; 
    gbc.weighty = 1.0d; 
    topChair.add(filler, gbc); //alla sedia in alto 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 0; 
    gbc.gridy = 1; 
    topChair.add(topPlayerPanel, gbc); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 1; 
    gbc.gridy = 0; 
    panel.add(topChair, gbc); //al panel 

    JPanel rightChair = new JPanel(new GridBagLayout()); 
    filler = createHorizontalFiller(); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 1; 
    gbc.gridy = 0; 
    gbc.fill = GridBagConstraints.HORIZONTAL; 
    gbc.weightx = 1.0d; 
    rightChair.add(filler, gbc); //alla sedia di destra 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 0; 
    gbc.gridy = 0; 
    rightChair.add(rightPlayerPanel, gbc); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 2; 
    gbc.gridy = 1; 
    panel.add(rightChair, gbc); //al panel 

    JPanel bottomChair = new JPanel(new GridBagLayout()); 
    filler = createVerticalFiller(); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 0; 
    gbc.gridy = 1; 
    gbc.fill = GridBagConstraints.VERTICAL; 
    gbc.weighty = 1.0d; 
    bottomChair.add(filler, gbc); //alla sedia in basso 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 0; 
    gbc.gridy = 0; 
    bottomChair.add(bottomPlayerPanel, gbc); 
    gbc = new GridBagConstraints(); 
    gbc.gridx = 1; 
    gbc.gridy = 2; 
    panel.add(bottomChair, gbc); //al panel
