如何用GridBagLayout填充BOTH和CENTER面板？

伙计！我怎样才能正确放置椅子？在下面的图片的第二帧中，我张贴了我想要放置这些对象的圈子。如何用GridBagLayout填充BOTH和CENTER面板？

我已经使用了4个BorderLayouts放置标签和图像，以便不给GridBagLayout的过于复杂，然后我将它们添加到GridBagLayout的是这样的：

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);

如果我把他们带PAGE_START，LINE_START，LINE_END，PAGE_END，展示位置是正确的。不过，这并不表明我的整体形象:(

您可以使用占用多余的空间GridBagLayout看不见的组件和“推”的其他组件周围。我用Box.Filler那些计算机图标推到表板。

     table.setBorder(BorderFactory.createMatteBorder(1, 1, 1, 1, Color.GRAY));

    } 

    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); 
      } 
     }); 
    } 

}

这应该让你开始

非常感谢，真的！但我还有一个问题......我在下面添加了更多细节 – libburst

非常感谢我使用的填料rewrited我的代码，但我有这个问题：！

例如为左椅子，我放置填料，然后将leftChairPanel（用BorderLayout.NORTH一个JLabel一个BorderLayout的它conists，并在BorderLayout.CENTER图像），但我得到这...也许我使用了错误的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
