java - 如何让两个 JPanel 水平拆分，每个 JPanel 始终占据屏幕的一半？

Question

如标题所述。我使用 BorderLayout() 将两个 JPanel 一个放在另一个之上。

import java.awt.*;
import javax.swing.*;

public class myForm(){
    public static void main(String[] args) {       
        JFrame myFrame = new JFrame("SingSong");
        myFrame.setLocation(100,100);
        myFrame.setSize(new Dimension(1024,800));
        myFrame.setLayout(new BorderLayout());
        JPanel jp = new JPanel();
        jp.setBackground(new Color(0x00FF00FF));
        JPanel jp2 = new JPanel(new BorderLayout());
        jp2.setBackground(new Color(0x00000000));

        jp.setPreferredSize(new Dimension(100,400));
        jp2.setPreferredSize(new Dimension(100,400));
        jp2.setLocation(0, 512);

        myFrame.add(jp2, BorderLayout.SOUTH);
        myFrame.add(jp, BorderLayout.NORTH);
    }
}        

它们各占一半，但我如何设置才能使它们始终各占 JFrame 的一半，即使在调整大小时也是如此？(P.S. 我通常使用更好的变量名，我只是把它作为 SSCCE 提了出来)

Answer 1

试试 GridLayout

JFrame myFrame = new JFrame("SingSong");
myFrame.setLocation(100, 100);
myFrame.setSize(new Dimension(1024, 800));

GridLayout layout = new GridLayout(2, 1);
myFrame.setLayout(layout);

JPanel jp = new JPanel();
jp.setBackground(new Color(0x00FF00FF));

JPanel jp2 = new JPanel(new BorderLayout());
jp2.setBackground(new Color(0x00000000));

myFrame.add(jp);
myFrame.add(jp2);

myFrame.setVisible(true);
