Java Swing+；MIG布局、其他组件的动态增长和收缩

我想实现让组件划分总可用空间，这取决于它们是应该缩小还是增大。这应该是动态的，也就是说；我没有任何关于添加到屏幕上的组件数量的信息。组件应根据其特性保持其高度或增长：

+++++++++++++++++++++++++++++++++
|   +-----------------------+   |
|   |       don't grow      |   |
|   +-----------------------+   |
|                               |
|   +-----------------------+   |
|   |                       |   |
|   |       growy           |   |
|   |                       |   |
|   +-----------------------+   |
|                               |
|   +-----------------------+   |
|   |       don't grow      |   |
|   +-----------------------+   |
|                               |
|   +-----------------------+   |
|   |       don't grow      |   |
|   +-----------------------+   |
|                               |
|   +-----------------------+   |
|   |                       |   |
|   |       growy           |   |
|   |                       |   |
|   +-----------------------+   |   
|                               |
|   +-----------------------+   |
|   |       don't grow      |   |
|   +-----------------------+   |

我能够创建以下结果：

提供的资料如下：

---

第二个和第五个文本字段按预期增长。其他组件保持其预期大小，尽管它们的容器不会“收缩”，并被处理为将其空间与其他组件分开。第二个和第五个文本字段应该占用所有的“额外”空间。

经过一些测试，我可能已经找到了一个适合我问题中提到的要求的解决方案

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            createAndShowGUI();
        }
    });
}

private static void createAndShowGUI() {
    JFrame frame = new JFrame("MigLayout");

    JPanel panel =  new JPanel(new MigLayout(new LC().debug(1000).flowY().fillX()));

    // 1rd set of components
    panel.add(new JLabel("Titel"), new CC().grow());
    panel.add(new JTextArea(), new CC().grow().push()); // this component can use all the extra space

    // 2st set of components
    panel.add(new JLabel("Titel"), new CC().grow());
    panel.add(new JTextField(), new CC().grow());
    panel.add(new JLabel("Description"), new CC().grow());

    // 3nd set of components
    panel.add(new JLabel("progress"), new CC().grow());
    panel.add(new JProgressBar(), new CC().grow());
    panel.add(new JTextArea(), new CC().grow().push()); // this component can use all the extra space


    frame.getContentPane().add(panel);

    frame.pack();
    frame.setVisible(true);
} 

结果：

正如您可能注意到的，屏幕上的两个组件占用了所有额外的空间，而其他组件保留其默认大小

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            createAndShowGUI();
        }
    });
}

private static void createAndShowGUI() {
    JFrame frame = new JFrame("MigLayout");

    JPanel panel =  new JPanel(new MigLayout(new LC().debug(1000).flowY().fillX()));

    // 1rd set of components
    panel.add(new JLabel("Titel"), new CC().grow());
    panel.add(new JTextArea(), new CC().grow().push()); // this component can use all the extra space

    // 2st set of components
    panel.add(new JLabel("Titel"), new CC().grow());
    panel.add(new JTextField(), new CC().grow());
    panel.add(new JLabel("Description"), new CC().grow());

    // 3nd set of components
    panel.add(new JLabel("progress"), new CC().grow());
    panel.add(new JProgressBar(), new CC().grow());
    panel.add(new JTextArea(), new CC().grow().push()); // this component can use all the extra space


    frame.getContentPane().add(panel);

    frame.pack();
    frame.setVisible(true);
}
