我有一个 GUI,其中有一个名为“listTable”的 JTable 容器。我想使用 AbstractTableModel 使用存储在链接列表中的数据填充 JTable。
基本上,我有一个 LinkedList 存储在 Processing.java 中。它包含从文本文件中检索到的所有数据。我创建了一个 AbstractTableModel 来告诉 JTable 如何填充。我现在要做的是用“链接列表的内容”填充 GUI_g 中的 JTable。
谁能告诉我该怎么做?
这是代码:
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);

chlblPanel.add(ch1Label);
chlblPanel.add(ch2Label);

listPanel.add(listTable);
