Answer 1

돈 그리드를 만들 때 GridBagLayout을 사용하지 마십시오. GridLayout을 사용하십시오. 여기에는 1 열 및 0 (fo r 가변 수) 행. JTextFields에 대해서만 JPanel을 만들고, GridLayout을주고, 원하는 경우 GridBagLayout을 사용하여 기본 GUI에이 JPanel을 추가 할 수 있습니다. 그러나 여기서 핵심은 각각 자체 레이아웃을 사용하여 JPanels를 중첩하는 것입니다.

다른 제안, 내가 좋아하는 변수 참조 :

JTextField word1; 
JTextField word2; 
JTextField word3; 
JTextField word4; 
JTextField word5; 
JTextField word6; 
JTextField word7; 
JTextField word8; 
JTextField word9; 
JTextField word10; 

내가 생각하는 그녀 정말 여기 배열이나 ArrayList를를 사용하지 않습니다? 아니면 JTable 일 수도 있습니다.

또한 JTextArea를 JScrollPane에 추가했지만 JScrollPane이 아닌 JTextArea를 GUI에 추가합니다.

import java.awt.BorderLayout; 
import java.awt.GridBagLayout; 
import java.awt.GridLayout; 
import java.awt.event.ActionEvent; 
import java.awt.event.KeyEvent; 
import javax.swing.*; 

public class Gsb2 extends JPanel { 
    private static final int WORD_FIELD_COUNT = 10; 
    private static final int COL_SIZE = 10; 
    private static final int TA_ROWS = 40; 
    private static final int TA_COLS = 40; 
    private JTextField[] wordFields = new JTextField[WORD_FIELD_COUNT]; 
    private int rows; 
    private JTextArea stuffArea = new JTextArea(TA_ROWS, TA_COLS); 

    public Gsb2() { 
     JPanel wordFieldsPanel = new JPanel(new GridLayout(0, 1)); 
     for (int i = 0; i < wordFields.length; i++) { 
      wordFields[i] = new JTextField(COL_SIZE); 
      wordFieldsPanel.add(wordFields[i]); 
     } 

     JPanel wrapWordFieldsPanel = new JPanel(new GridBagLayout()); 
     wrapWordFieldsPanel.add(wordFieldsPanel); 

     JPanel buttonPanel = new JPanel(new GridLayout(1, 0, 5, 0)); 
     buttonPanel.add(new JButton(new MyAction("Restart", KeyEvent.VK_R))); 
     buttonPanel.add(new JButton(new MyAction("Exit", KeyEvent.VK_X))); 
     buttonPanel.add(new JButton(new MyAction("BONANZA!", KeyEvent.VK_B))); 

     JScrollPane scrollPane = new JScrollPane(stuffArea); 

     JPanel rightPanel = new JPanel(new BorderLayout(5, 5)); 
     rightPanel.add(wrapWordFieldsPanel, BorderLayout.CENTER); 
     rightPanel.add(buttonPanel, BorderLayout.PAGE_END); 

     setLayout(new BorderLayout(5, 5)); 
     setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5)); 
     add(rightPanel, BorderLayout.LINE_START); 
     add(scrollPane, BorderLayout.CENTER); 

    } 

    private class MyAction extends AbstractAction { 
     public MyAction(String name, int mnemonic) { 
      super(name); 
      putValue(MNEMONIC_KEY, mnemonic); 
     } 

     @Override 
     public void actionPerformed(ActionEvent e) { 
      // TODO add code 

     } 
    } 

    private static void createAndShowGui() { 
     Gsb2 mainPanel = new Gsb2(); 

     JFrame frame = new JFrame("Gsb2"); 
     frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); 
     frame.getContentPane().add(mainPanel); 
     frame.pack(); 
     frame.setLocationByPlatform(true); 
     frame.setVisible(true); 
    }

OK, OK, "경기 사양"에 사용 BoxLayout가 :

예를 들어

    private JTextField[] wordFields = new JTextField[WORD_FIELD_COUNT]; 
    private int rows; 
    private JTextArea stuffArea = new JTextArea(TA_ROWS, TA_COLS); 

    public Gsb3() { 
     JPanel wordFieldsPanel = new JPanel(new GridLayout(0, 1)); 
     for (int i = 0; i < wordFields.length; i++) { 
      wordFields[i] = new JTextField(COL_SIZE); 
      wordFieldsPanel.add(wordFields[i]); 
     } 

     JPanel wrapWordFieldsPanel = new JPanel(new GridBagLayout()); 
     wrapWordFieldsPanel.add(wordFieldsPanel); 

     JPanel buttonPanel = new JPanel(new GridLayout(1, 0, 5, 0)); 
     buttonPanel.add(new JButton(new MyAction("Restart", KeyEvent.VK_R))); 
     buttonPanel.add(new JButton(new MyAction("Exit", KeyEvent.VK_X))); 
     buttonPanel.add(new JButton(new MyAction("BONANZA!", KeyEvent.VK_B))); 
     buttonPanel.setMaximumSize(buttonPanel.getPreferredSize()); 

     JScrollPane scrollPane = new JScrollPane(stuffArea); 

     setLayout(new BoxLayout(this, BoxLayout.LINE_AXIS)); 
     setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5)); 
     add(wrapWordFieldsPanel); 
     add(Box.createHorizontalStrut(5)); 
     add(buttonPanel); 
     add(Box.createHorizontalStrut(5)); 
     add(scrollPane); 

    } 

    private class MyAction extends AbstractAction { 
     public MyAction(String name, int mnemonic) { 
      super(name); 
      putValue(MNEMONIC_KEY, mnemonic);

     frame.pack();

     frame.setVisible(true); 
    } 

    public static void main(String[] args) {

}
