GridBagLayout ile panelleri hizalama

Question

Ben java için tam olarak yeni değilim (bunu bir yıldır kullanıyordum) ama bu benim ilk adımı atıyor. Bir kerede hem soket hem de salıncak öğrenmek için çok basit bir sohbet istemcisi yapmaya çalışıyorum. Sorum şu: "Panellerimi doğru şekilde hizalamak için ne yapmalıyım?" Çok fazla şey denedim (kodumda olmasa da). Genellikle böyle bir şeyi kendi başıma yapıyorum, ama yardım istemek zorunda olduğum noktaya geldim. Wieghtx'i değiştirmem gerek mi? İstemcinin nasıl görünmesini istediğim, bunun gibi bir şey.

Bu

şu anda böyle görünüyor.

İşte benim kodudur.

package com.client.core; 

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


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); 

    //Panels 
    JPanel display = new JPanel(); 
    JPanel chat = new JPanel(); 
    chat.setLayout(new GridBagLayout()); 
    JPanel users = new JPanel(); 


    display.setBackground(Color.blue); 
    c.gridx = 0; 
    c.gridy = 0; 
    c.insets= new Insets(5,5,5,5); 
    window.add(display, c); 

    chat.setBackground(Color.red); 
    c.gridx = 0; 
    c.gridy = 3; 
    c.gridheight = 2; 
    c.gridwidth = 1; 
    c.insets= new Insets(5,5,5,5); 
    window.add(chat, c); 

    users.setBackground(Color.green); 
    c.gridx = 2; 
    c.gridy = 0; 
    c.insets= new Insets(5,5,5,5); 
    window.add(users, c); 

    //Buttons 


    //Text fields 
    JTextArea text = new JTextArea("DEREADFADSFEWFASDFSADFASDF"); 
    c.gridx = 0; 
    c.gridy = 0; 
    chat.add(text); 
    JTextField input = new JTextField("type here to chat", 50); 
    c.gridx = 0; 
    c.gridy = 1; 
    c.insets= new Insets(5,5,5,5); 
    chat.add(input); 


    add(window); 


} 

static class ActLis implements ActionListener{ 

    @Override 
    public void actionPerformed(ActionEvent e) { 
     // TODO Auto-generated method stub 

    } 

} 
} 

Answer 1

yapmanız ve muhtemelen bir çıkış olarak böyle bir şey isteseydim o zaman GridBagLayout

Answer 2

karıştırmasını istenen bir sonuç daha basit

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); 

Way verir ne olabilir:

Bu c gazel örneği, son ButtonPanel kaldırabilirsiniz gerçi bunu gerekmiyorsa:
