如何使JTable的单元格不可编辑，但可选择 [英] How to make cells of JTable non-editable, but selectable

问题描述

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？

I have overridden the isCellEditable() method of class JTable in my code to make the cells of my JTable non-editable but selectable, but the cells are still editable. How do I solve this problem?

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());
        }
    }
}

推荐答案

我认为你需要覆盖TableModel的isCellEditable（）方法而不是JTable，如下所示：

I believe you need to override the isCellEditable() method of the TableModel rather than the JTable, like so:

public class NonEditableModel extends DefaultTableModel {

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

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

也可以简单地使用匿名类。

It is also possible to simply override the method using an anonymous class.

 DefaultTableModel tableModel = new DefaultTableModel(data, col) {

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

此问题演示了如何执行覆盖内联，如果你只需要实例化一次TableModel就很方便：
