如何使JTable的单元格不可编辑,但可选择

Question

我在我的代码中重写了JTable类的isCellEditable()方法,使我的JTable的单元格不可编辑但可选,但单元格仍然可编辑.我该如何解决这个问题？

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

public class A extends JTable{

    JFrame frame = new JFrame();
    Object data[][] = {{"1","Jahanzeb"},{"2","Ahmed"},{"3","Shaikh"}};
    String col[] = {"#","Names"};
    DefaultTableModel tableModel = new DefaultTableModel(data, col);
    JTable table = new JTable(tableModel);
    JScrollPane scroll = new JScrollPane(table);

    public static void main(String arg[]){
        new A();
    }

    public A() {

        table.addMouseListener(new Click());
         table.setModel(tableModel);
        frame.setSize(500,500);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(scroll);
        frame.add(table);
        frame.setVisible(true);
    }


    @Override
    public boolean isCellEditable(int row, int column){
        return false;
    }

    class Click extends MouseAdapter{
        public void mouseClicked(MouseEvent e) {
            if(e.getClickCount()==2)
                System.out.println(table.getSelectedRow());
        }
    }
}

我相信你需要覆盖TableModel的isCellEditable()方法而不是JTable,如下所示:

public class NonEditableModel extends DefaultTableModel {

    NonEditableModel(Object[][] data, String[] columnNames) {
        super(data, columnNames);
    }

    @Override
    public boolean isCellEditable(int row, int column) {
        return false;
    }
}

也可以使用匿名类简单地覆盖该方法.

 DefaultTableModel tableModel = new DefaultTableModel(data, col) {

    @Override
    public boolean isCellEditable(int row, int column) {
        return false;
    }
}

这个问题演示了如何执行覆盖内联,如果你只需要实例化TableModel一次就很方便: 如何使JTable不可编辑
