'listTable'というJTableのコンテナを持つGUIがあります。AbstractTableModelを使用して、リンクリストに格納されているデータをJTableに入力したいと思います。
基本的に、Processing.javaにLinkedListが格納されています。テキストファイルから取得したすべてのデータが含まれています。JTableにデータを入力する方法を指示するAbstractTableModelを作成しました。ここで実行したいのは、GUI_gのJTableに「リンクリストの内容」を入力することです。
誰でもこれを行う方法を教えてもらえますか？
コードは次のとおりです。
GUI_g：
import java.awt.*;
import javax.swing.*;
import javax.swing.JTable;
public class GUI_g extends JFrame {
public void buildGui() {
JFrame frame = new JFrame("Hotel TV Scheduler");
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new BorderLayout(0,0));
JPanel chPanel = new JPanel();
chPanel.setLayout(new GridLayout(3,1));
JPanel listPanel = new JPanel();
listPanel.setLayout(new GridLayout(3,2,1,0));
JPanel infoPanel = new JPanel();
infoPanel.setLayout(new GridLayout(0,3, 1, 0));
JPanel addPanel = new JPanel();
addPanel.setLayout(new GridLayout(0,3));
JPanel chlblPanel = new JPanel();
chlblPanel.setLayout(new GridLayout(1,2));
JPanel tablePanel = new JPanel();
tablePanel.setLayout(new GridLayout(1,2));
JPanel rmvbtnPanel = new JPanel();
rmvbtnPanel.setLayout(new GridLayout(1,2));
JPanel centrePanel = new JPanel();
centrePanel.setLayout(new GridLayout(0,3));
// mainPanel.add(chPanel, BorderLayout.WEST);
// mainPanel.add(listPanel, BorderLayout.EAST);
mainPanel.add(centrePanel, BorderLayout.CENTER);
