我的問題是,在我的代碼中,我在主類中創建了一個JTable。現在我正在創建一個線程完成一些任務,並收集一些數據,只要線程收集它們就可以填充JTable。這個線程應該運行一段時間。所以我可以通過創建的線程訪問主類的JTable。通過線程訪問父類對象
編輯:我在這裏提供我的代碼。
Test.java
package test;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.AbstractTableModel;
import java.awt.*;
public class Test implements ActionListener {
Thread t;
JTable table;
JScrollPane scrollPane;
JButton b;
JFrame frame;
public void body() {
frame = new JFrame("TableDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new FlowLayout());
table = new JTable(new MyTableModel());
table.setPreferredScrollableViewportSize(new Dimension(500, 70));
table.setFillsViewportHeight(true);
scrollPane = new JScrollPane(table);
frame.add(scrollPane);
b = new JButton("OK");
frame.add(b);
thread a = new thread(new MyTableModel());
t = new Thread(a);
frame.pack();
frame.setVisible(true);
b.addActionListener(this);
}
public static void main(String[] args) {
new Test().body();
}
@Override
public void actionPerformed(ActionEvent e) {
t.start();
}
}
class MyTableModel extends AbstractTableModel {
private String[] columnNames = {
"First Name",
"Last Name",
"Sport"
};
private Object[][] data = {
{
"a",
"a",
"a"
}
};
@Override
public int getColumnCount() {
return columnNames.length;
}
public int getRowCount() {
return data.length;
}
public String getColumnName(int col) {
return columnNames[col];
}
public Object getValueAt(int row, int col) {
return data[row][col];
}
public Class getColumnClass(int c) {
return getValueAt(0, c).getClass();
}
public boolean isCellEditable(int row, int col) {
if (col < 3) {
return false;
} else {
return true;
}
}
public void setValueAt(Object value, int row, int col) {
data[row][col] = value;
fireTableCellUpdated(row, col);
}
}
thread.java
package test;
public class thread implements Runnable {
MyTableModel model;
thread(MyTableModel model){
this.model = model;
}
@Override
public void run() {
Object aa = "new value";
this.model.setValueAt(aa, 0, 0);
System.out.println(this.model.getValueAt(0, 0));
}
}
什麼其實我是想在0,0 JTable的顯示屏幕上的價值應該從「一個「到」新價值「。
請給予一些幫助。
一些示例代碼? –
