如何在框架中水平划分三等份 java

Question

我使用 GridBagConstraints 将帧分成三部分，例如粉色背景的水平部分和黄色和蓝色背景的垂直部分，就像图像中那样，enter image description here

我正在使用以下代码来执行此操作，

 public Main() 
       {
           JFrame maFrame = new JFrame("The main screen"); //creating main Jframe
           maFrame.setSize(1000, 700);
           Container container = maFrame.getContentPane();
           container.setLayout(new GridBagLayout()); //setting layout of main frame
           GridBagConstraints cns = new GridBagConstraints(); //creating constraint

           JPanel headPanel = new JPanel(); //creating the header panel
           cns.gridx = 0;
           cns.gridy = 1;
           cns.weightx = 0.3;
           cns.weighty = 0.7;
           cns.anchor = GridBagConstraints.FIRST_LINE_START;
           cns.fill = GridBagConstraints.BOTH;
           maFrame.setLocationRelativeTo(null); //centering frame
           headPanel.setBackground(Color.YELLOW);
           container.add(headPanel, cns);

           JPanel panel = new JPanel();
           panel.setBackground(Color.BLUE);
           cns.gridx = 1;
           cns.gridy = 1;
           cns.weightx = 0.7;
           cns.weighty = 0.7;
           cns.anchor = GridBagConstraints.PAGE_START;
           cns.fill = GridBagConstraints.BOTH;
           container.add(panel, cns);

           JPanel panel1 = new JPanel();
           panel1.setBackground(Color.PINK);
           cns.gridx = 0;
           cns.gridy = 0;
           cns.gridwidth = 2;
           cns.weightx = 1.0;
           cns.weighty = 0.3;
           cns.anchor = GridBagConstraints.LAST_LINE_START;
           cns.fill = GridBagConstraints.BOTH;
           container.add(panel1, cns);     

           maFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //setting the default close operation of JFrame
           maFrame.pack();
           maFrame.setVisible(true); //making the frame visible
       }

我想把粉红色背景部分分成三部分，黄色背景部分分成两部分。我试过这样做。但它不适合我。我不想使用 splitpane 来执行此操作。是否可以使用 GridBagConstraints 来实现？你能给我一个想法吗？提前致谢。

简单的方法是使用 GridLayout 将 contentPane 分成两行，然后将底行分成两列。

import javax.swing.*;
import java.awt.*;
class JpanelSplit {
    JFrame frame;
    JPanel contentPane;
    JPanel pinkPanel;
    JPanel yellowPanel;
    JPanel bluePanel;
    JPanel twoPanelContainer;

    public JpanelSplit() {
        frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        contentPane = new JPanel(new GridLayout(2,1));
        pinkPanel = new JPanel();
        pinkPanel.setBackground(Color.PINK);

        yellowPanel = new JPanel();
        yellowPanel.setBackground(Color.YELLOW);    

        bluePanel = new JPanel();
        bluePanel.setBackground(Color.BLUE);

        twoPanelContainer = new JPanel(new GridLayout(1,2));
        twoPanelContainer.add(yellowPanel);
        twoPanelContainer.add(bluePanel);

        contentPane.add(pinkPanel);
        contentPane.add(twoPanelContainer);

        frame.setContentPane(contentPane);
        frame.pack();
        frame.setVisible(true);

    }

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