如何将复选框添加到 JTABLE Swing [英] How to add checkboxes to JTABLE swing

问题描述

有谁知道如何将 JCheckBox 放在 JTable 列中?像这样:

我从如何使用表格 >

提前致谢.

解决方案

1) JTable 知道 JCheckbox-in Boolean TableCellRenderers 和 TableCellEditor 默认情况下，然后有声明一些事情会适得其反，

2) AbstractTableModel 应该很有用，其中在JTable中需要减少/限制/改变嵌套和继承方法，默认实现在DefaultTableModel，

3) 考虑使用 DefaultTableModel，(如果您不确定如何工作)而不是 AbstractTableModel，

可以从简单的代码生成:

import javax.swing.*;导入 javax.swing.table.*;公共类 TableCheckBox 扩展 JFrame {private static final long serialVersionUID = 1L;私有 JTable 表；公共表检查框(){Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};对象[][] 数据 = {{购买"，IBM"，新整数(1000)，新双(80.50)，假}，{卖"，微软"，新整数(2000)，新双(6.25)，真}，{卖"，苹果"，新整数(3000)，新双(7.35)，真}，{"Buy", "Nortel", new Integer(4000), new Double(20.00), false}};DefaultTableModel 模型 = 新的 DefaultTableModel(data, columnNames);表 = 新 JTable(模型){private static final long serialVersionUID = 1L;/*@覆盖公共类 getColumnClass(int column) {返回 getValueAt(0, column).getClass();}*/@覆盖公共类 getColumnClass(int column) {开关(列){案例0:返回 String.class;情况1:返回 String.class;案例2:返回整数类；案例3:返回 Double.class;默认:返回 Boolean.class;}}};table.setPreferredScrollableViewportSize(table.getPreferredSize());JScrollPane scrollPane = new JScrollPane(table);getContentPane().add(scrollPane);}公共静态无效主(字符串 [] args){SwingUtilities.invokeLater(new Runnable() {@覆盖公共无效运行(){TableCheckBox 框架 = new TableCheckBox();frame.setDefaultCloseOperation(EXIT_ON_CLOSE);框架.pack();frame.setLocation(150, 150);frame.setVisible(true);}});}}

Does anyone know how to put a JCheckBox in a JTable column? Something like this:

I took this from How To use Tables

Thanks in advance.

解决方案

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override
            public Class getColumnClass(int column) {
            return getValueAt(0, column).getClass();
            }*/
            @Override
            public Class getColumnClass(int column) {
                switch (column) {
                    case 0:
                        return String.class;
                    case 1:
                        return String.class;
                    case 2:
                        return Integer.class;
                    case 3:
                        return Double.class;
                    default:
                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}
