java - 请给出一个简单的例子，如何使用 MigLayout 模拟 BorderLayout？

Question

我希望布局的 WEST 和 EAST 部分具有恒定的宽度。如何使用 MigLayout 进行设置？

更新

以下代码不会像边框布局那样调整大小:

package testing.Test_MigLayout_01;

import javax.swing.JButton;
import javax.swing.JRootPane;
import javax.swing.SwingUtilities;

import net.miginfocom.swing.MigLayout;

public class App201210042244 
{

private class JFrame extends javax.swing.JFrame {

    {
        setLayout(new MigLayout());

        add(new JButton("1"), "dock east, width 120");
        add(new JButton("2"), "west");
        add(new JButton("3"), "center");
        add(new JButton("4"), "north");
        add(new JButton("5"), "south");

    }

}

public App201210042244() {
     SwingUtilities.invokeLater(new Runnable() {

            public void run() {
                JFrame jFrame = new JFrame();
                jFrame.pack();
                jFrame.setVisible(true);

            }
        });
}


public static void main( String[] args )
{
   new App201210042244();
}
}

窗口内部的大小保持不变:

Answer 1

panel.add(new JButton("1"), "dock east, width 120");
panel.add(new JButton("2"), "west");
panel.add(new JButton("3"), "center");
panel.add(new JButton("4"), "north");
panel.add(new JButton("5"), "south");

dock 关键字可以省略。

更新:

如果您希望在调整窗口大小时所有组件都展开:

panel.setLayout(new MigLayout("fill"));
panel.add(new JButton("1"), "dock east, width 120");
panel.add(new JButton("2"), "west");
panel.add(new JButton("3"), "center, grow");
panel.add(new JButton("4"), "north");
panel.add(new JButton("5"), "south");
