我对 java 并不完全陌生（我已经使用它一年了），但这是我第一次尝试摇摆。我正在尝试制作一个非常简单的聊天客户端来同时学习套接字和摆动。我的问题是“我必须怎么做才能正确对齐我的面板？”。我已经尝试了很多东西（虽然我的代码中没有它）。通常我自己做这样的事情，但我到了需要寻求帮助的地步。我需要改变重量吗？我希望客户看起来像这样。

这就是它目前的样子。

这是我的代码。

package com.client.core;

public class Window extends JFrame{

private int screenWidth = 800;
private int screenHeight = 600;

public Window(){

    //Initial Setup
    super("NAMEHERE - Chat Client Alpha v0.0.1");
    setResizable(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setSize(screenWidth,screenHeight);
    GridBagConstraints c = new GridBagConstraints();

    //Main Panel
    JPanel window = new JPanel();
    window.setLayout(new GridBagLayout());
    window.setBackground(Color.black);

如果您想要这样的输出：

您可以从此代码示例中获取帮助，但ButtonPanel如果不需要，您可以删除最后一个：

你可以做什么，并且可能会给出想要的结果

JPanel somethingHere = ...;
JPanel chat = ...;
JPanel userList = ...;

JPanel leftPanel = new JPanel( new BorderLayout() );
leftPanel.add( somethingHere, BorderLayout.CENTER );
leftPanel.add( chat, BorderLayout.SOUTH );

JPanel total = new JPanel( new BorderLayout() );
total.add( leftPanel, BorderLayout.CENTER );
total.add( userList, BorderLayout.EAST );

更简单然后搞砸GridBagLayout

到目前为止，这是我得出的结论。红框是我打算用 LWJGL 添加一个简单的 2D 头像界面的地方。

在此处输入图像描述

这是它的代码

package com.client.core;

import java.awt.*;
import java.awt.event.*;

import javax.swing.*;
import javax.swing.event.DocumentEvent;
import javax.swing.event.DocumentListener;


public class Window extends JFrame{

private int screenWidth = 800;
private int screenHeight = 600;

public Window(){

    //Initial Setup
    super("NAMEHERE - Chat Client Alpha v0.0.1");
    setResizable(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setSize(screenWidth,screenHeight);


    //Main Panels
    JPanel window = new JPanel(new BorderLayout());
    JPanel center = new JPanel(new BorderLayout());
    JPanel right = new JPanel(new BorderLayout());


    //Panels
    JPanel display = new JPanel( new BorderLayout());
    display.setBackground(Color.red);
    JPanel chat = new JPanel();
    chat.setLayout(new BoxLayout(chat, BoxLayout.Y_AXIS));
    chat.setBackground(Color.blue);
    JPanel users = new JPanel(new BorderLayout());
    users.setBackground(Color.green);


    //TextFields
    JTextArea chatBox = new JTextArea("Welcome to the chat!", 7,50);
    chatBox.setEditable(false);
    JTextField chatWrite = new JTextField();
    JScrollPane userList = new JScrollPane();
    JTextField userSearch = new JTextField(10);
    userList.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
    users.add(userList);
    users.add(userSearch, BorderLayout.NORTH);
    chat.add(chatBox);
    chat.add(chatWrite);
    chat.setBorder(BorderFactory.createEmptyBorder(1, 1, 1, 1));

    //Menu bar
    JMenuBar menu = new JMenuBar();
        JMenu file = new JMenu("File");
            JMenuItem exit = new JMenuItem("Exit");
            JMenuItem ipconnect = new JMenuItem("Connect to IP");
    file.add(ipconnect);
    file.add(exit);
    menu.add(file);


    //Main window adding
    right.add(users);
    center.add(display, BorderLayout.CENTER);
    center.add(chat, BorderLayout.SOUTH);
    window.add(center, BorderLayout.CENTER);
    window.add(right, BorderLayout.EAST);
    window.add(menu, BorderLayout.NORTH);
    add(window);




    //Listeners
    chatWrite.addKeyListener(new KeyLis());
    ipconnect.addActionListener(new ActLis());
    exit.addActionListener(new ActLis());
}







static class KeyLis implements KeyListener{

    @Override
    public void keyPressed(KeyEvent e) {
        if(e.getKeyCode() == KeyEvent.VK_ENTER){
            System.out.println("Message recieved.");
        }

    }

    @Override
    public void keyReleased(KeyEvent e) {
        // TODO Auto-generated method stub

    }

    @Override
    public void keyTyped(KeyEvent e) {
        // TODO Auto-generated method stub

    }



}

static class ActLis implements ActionListener{

    @Override
    public void actionPerformed(ActionEvent e) {
    if(e.getActionCommand() == "Exit"){
        System.exit(0);
    } else if(e.getActionCommand() == "Connect to IP"){
        System.out.println("Connecting....");
        JFrame frameip = new JFrame();
        JPanel panelip = new JPanel();  
        JButton buttonip = new JButton("Hello");
        frameip.add(panelip);
        panelip.add(buttonip);
        JDialog ippop =  new JDialog(frameip, "Enter IP", false);
    }


    }
}
}

我必须使用 GridBagLayout 构建类似的布局。下面的代码显示了我是如何实现它的。

在此处输入图像描述

import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class GridBagLayoutTest {
    public GridBagLayoutTest() {
    
    JFrame jframe = new JFrame();
    jframe.setLayout(new GridBagLayout());
    jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    jframe.setSize(800, 600);
    jframe.setVisible(true);
    
    // Left
    JPanel leftPanel = new JPanel(new GridBagLayout());
    leftPanel.setBackground(Color.YELLOW);
    
    GridBagConstraints gridBagConstraints = new GridBagConstraints();
    gridBagConstraints.fill = GridBagConstraints.BOTH;
    gridBagConstraints.weightx = .7f;
    gridBagConstraints.weighty = 1f;
    gridBagConstraints.gridx = 0;
    gridBagConstraints.gridy = 0;
    
    jframe.add(leftPanel, gridBagConstraints);
    
    JPanel leftTopPanel = new JPanel(new FlowLayout());
    leftTopPanel.setBackground(Color.RED);
    
    GridBagConstraints gridBagConstraints0 = new GridBagConstraints();
    gridBagConstraints0.fill = GridBagConstraints.BOTH;
    gridBagConstraints0.weightx = 1f;
    gridBagConstraints0.weighty = .7f;
    gridBagConstraints0.gridx = 0;
    gridBagConstraints0.gridy = 0;
    
    leftPanel.add(leftTopPanel, gridBagConstraints0);
    
    JPanel leftMiddlePanel = new JPanel(new FlowLayout());
    leftMiddlePanel.setBackground(Color.BLACK);
    
    gridBagConstraints0 = new GridBagConstraints();
    gridBagConstraints0.fill = GridBagConstraints.BOTH;
    gridBagConstraints0.weightx = 1f;
    gridBagConstraints0.weighty = .2f;
    gridBagConstraints0.gridx = 0;
    gridBagConstraints0.gridy = 1;
    
    leftPanel.add(leftMiddlePanel, gridBagConstraints0);
    
    JPanel leftBottomBottomPanel = new JPanel(new FlowLayout());
    leftBottomBottomPanel.setBackground(Color.PINK);
    
    gridBagConstraints0 = new GridBagConstraints();
    gridBagConstraints0.fill = GridBagConstraints.BOTH;
    gridBagConstraints0.weightx = 1f;
    gridBagConstraints0.weighty = .1f;
    gridBagConstraints0.gridx = 0;
    gridBagConstraints0.gridy = 2;
    
    leftPanel.add(leftBottomBottomPanel, gridBagConstraints0);
    
    // Right
    JPanel rightPanel = new JPanel();
    rightPanel.setBackground(Color.GREEN);
    
    gridBagConstraints = new GridBagConstraints();
    gridBagConstraints.fill = GridBagConstraints.BOTH;
    gridBagConstraints.weightx = .3f;
    gridBagConstraints.weighty = 1f;
    gridBagConstraints.gridx = 1;
    gridBagConstraints.gridy = 0;
    
    jframe.add(rightPanel, gridBagConstraints);
}


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