如何在作为BufferedImage（）的JFrame中添加JPanel

到目前为止我有这个： enter image description here

逻辑是：

a。）我将按下按钮'S'然后游戏将开始

b。）JTextArea将显示用户的对话（注意：我没有为了调试目的而禁用它）

c。）JTextField将是用户输入文本的字段。

我有这些工作代码：

package game;

//import 


public class Game extends JFrame {


public static final String SERVER_IP = "localhost";


public static final int WIDTH = 1200;
public static final int HEIGHT = 800;
public static final int SCALE = 1;


private final int FPS = 60;
private final long targetTime = 1000 / FPS;

private BufferedImage backBuffer;

public KeyboardInput input;
private Stage stage;

public String username = "";

public GameClient client;
public static Game game;

public static String message = "";

private Tank tank;

private javax.swing.JButton jButton1;
private javax.swing.JPanel jPanel1;
private javax.swing.JScrollPane jScrollPane1;
private javax.swing.JTextArea jTextArea1;
private javax.swing.JTextField jTextField1;

public Game() throws HeadlessException {
    setSize(1000, 1000);
    addWindowListener(new WinListener());
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setLocationRelativeTo(null);
    setResizable(false);
    setVisible(true);
    //setUndecorated(false);
    addKeyListener(input);
    setVisible(true);
}    
public void init() {
    this.game = this;
    input = new KeyboardInput();

    //this.setSize(WIDTH, HEIGHT);
    //this.setLocationRelativeTo(null);
    //this.setResizable(false);


  Dimension expectedDimension = new Dimension(900, 50);
  Dimension expectedDimension2 = new Dimension(100, 50);
   jButton1 = new JButton("jButton1");

jTextArea1 = new JTextArea(6,6);
jTextArea1.setBounds(0,200,200,200);
jTextArea1.setBackground(Color.BLUE);
//jTextArea1.setFocusable(false);
jTextField1 = new JTextField("jTextField1");
JPanel panel2 = new JPanel();
panel2.setLayout(new FlowLayout());
panel2.add(jTextField1);
panel2.add(jButton1);
panel2.setBackground(Color.BLACK); // for debug only
panel2.setPreferredSize(expectedDimension);
panel2.setMaximumSize(expectedDimension);
panel2.setMinimumSize(expectedDimension);
jPanel1 = new JPanel();
jPanel1.setLayout(new BoxLayout(jPanel1, BoxLayout.Y_AXIS));
jPanel1.add(jTextArea1);
jPanel1.add(panel2);
jPanel1.setBackground(Color.RED); // for debug only
jPanel1.setPreferredSize(expectedDimension2);
jPanel1.setMaximumSize(expectedDimension2);
jPanel1.setMinimumSize(expectedDimension2);
jScrollPane1 = new JScrollPane(jPanel1,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
setContentPane(jScrollPane1);

System.out.println("init");
revalidate();

    client = new GameClient(SERVER_IP, this);

    backBuffer = new BufferedImage(800* SCALE,600 * SCALE, BufferedImage.TYPE_INT_RGB);
}

    return stage;
}

public class WinListener extends WindowAdapter {

    @Override
    public void windowClosing(WindowEvent e) {
        disconnect();
        System.exit(0);
    }

}


public void disconnect() {
    Packet01Disconnect p = new Packet01Disconnect(username);
    p.writeData(client);
    client.closeSocket();
    System.exit(0);
}

我希望有人会帮我解决我的问题。

答案 0 :(得分：4)

  • 设置＆＃34; main＆＃34;容器布局管理器到BorderLayout
  • 点击此处，在GameInterface位置
    • 中添加BorderLayout.CENTER
  • 创建另一个（＆＃34;互动＆＃34;）容器并将其布局管理器设置为BorderLayout，将其添加到＆＃34; main＆＃34;容器BorderLayout.SOUTH职位
  • 将JTextArea换成JScrollPane并将其添加到您的＆＃34;互动＆＃34;的BorderLayout.CENTER位置容器
  • 创建另一个容器（＆＃34;消息＆＃34;），这可以使用GridBagLayout。在此处添加JTextField（将GridBagConstraints#weightx设置为0并将GridBagConstraints#weightx设置为1）并将按钮添加到下一个单元格（{{1设置为GridBagConstraints#gridx，1设置为GridBagConstraints#weightx）

注意：

0不是应该如何进行自定义绘画。相反，覆盖Graphics g = getGraphics();等组件的paintComponent并在那里执行自定义绘画！
