swing Java鼠标事件在JTable中不起作用

Question

我在尝试在我的JTable工作上创建单击行事件时遇到问题。我已将该事件添加到JTable中，但当我运行程序并单击该行时，它不会显示消息

这是我的代码：

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.sql.SQLException;

import javax.swing.*;
import javax.swing.event.ListSelectionEvent;
import javax.swing.event.TableModelListener;
import javax.swing.table.DefaultTableModel;

public class listContacts extends JFrame {

public listContacts(){

    setLayout(new FlowLayout());

    String[] columnNames = {"GSD Number", "Scheduled Time"};
    Object [][] dataTable = {};

    DefaultTableModel listTableModel;
    listTableModel = new DefaultTableModel(dataTable, columnNames) {

        //Prevent user from editing the cells
        public boolean isCellEditable(int rowIndex, int mCollIndex){
            return false;
        }
    };

    int cont = 1;

    while(cont < 10){
        listTableModel.addRow(new Object[] {cont, cont + cont} );
        cont++;
    }


    JTable listTable = new JTable(listTableModel);

  //This is the code that adds the event to the JTable
    listTable.addMouseListener(new MouseAdapter() {

        public void rowClicked(MouseEvent e){
            JOptionPane.showMessageDialog(null,"You've clicked on this row");
        }

    });

    listTable.setCellEditor(null);

    JScrollPane pane = new JScrollPane(listTable);
    add(pane);
}


public static void main(String[] args) {
    listContacts tester = new listContacts();
    tester.setVisible(true);
    tester.setDefaultCloseOperation(EXIT_ON_CLOSE);
    tester.setSize(800, 200);
    tester.setTitle("Just a test");
}

}

有人能帮忙吗？提前谢谢

Answer 1

试试这个

listTable.addMouseListener(new MouseAdapter() {

    // Add this annotation to your method
    @Override
    public void rowClicked(MouseEvent e){
        JOptionPane.showMessageDialog(null,"You've clicked on this row");
    }

});

现在编译它。。。看看它是怎么失败的

rowClicked不是MouseAdapter继承的任何接口或类的方法，因此，没有任何东西可以调用它，因为对。。。这不在鼠标事件通知的合同要求范围内

更多细节请看How to Write a Mouse Listener和^{}

谢谢你，我听从了你的建议，把这个方法的名字改成了mouseClicked，活动就成功了。这是我的代码：

listTable.addMouseListener(new MouseAdapter() {

        // Add this annotation to your method
        @Override
        public void mouseClicked(MouseEvent e){
            JOptionPane.showMessageDialog(null,"You've clicked on this row");
        }

    });

再次感谢你的帮助
