给jtable添加单选框的代码

以下是给 JTable 添加单选框的示例代码：

import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableColumn;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class TestJTable extends JFrame {
    private JTable table;
    private JRadioButton radioButton1;
    private JRadioButton radioButton2;
    private ButtonGroup buttonGroup;

    public TestJTable() {
        setTitle("JTable with Radio Buttons");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(500, 300);
        setLocationRelativeTo(null);

        // Create the table model
        String[] columnNames = {"Name", "Age", "Gender"};
        Object[][] data = {
                {"John", new Integer(30), new Boolean(false)},
                {"Mary", new Integer(25), new Boolean(true)},
                {"Bob", new Integer(40), new Boolean(false)},
                {"Dan", new Integer(20), new Boolean(true)}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);

        // Create the table with the model
        table = new JTable(model);
        table.setAutoCreateRowSorter(true);

        // Set the checkbox column editor and renderer
        TableColumn column = table.getColumnModel().getColumn(2);
        column.setCellEditor(new RadioButtonEditor());
        column.setCellRenderer(new RadioButtonRenderer());

        // Add the table to a scroll pane
        JScrollPane scrollPane = new JScrollPane(table);

        // Add the radio buttons to a button group
        radioButton1 = new JRadioButton("Male");
        radioButton2 = new JRadioButton("Female");
        buttonGroup = new ButtonGroup();
        buttonGroup.add(radioButton1);
        buttonGroup.add(radioButton2);

        // Add the radio buttons to the content pane
        JPanel radioPanel = new JPanel();
        radioPanel.add(radioButton1);
        radioPanel.add(radioButton2);
        add(radioPanel, BorderLayout.NORTH);
        add(scrollPane, BorderLayout.CENTER);
    }

    // The RadioButtonEditor class
    class RadioButtonEditor extends DefaultCellEditor implements ActionListener {
        private JRadioButton button;

        public RadioButtonEditor() {
            super(new JCheckBox());
            button = new JRadioButton();
            button.addActionListener(this);
            button.setHorizontalAlignment(JRadioButton.CENTER);
        }

        public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
            if (value == null) {
                button.setSelected(false);
            } else {
                button.setSelected((Boolean) value);
            }
            return button;
        }

        public Object getCellEditorValue() {
            return button.isSelected();
        }

        public void actionPerformed(ActionEvent e) {
            fireEditingStopped();
        }
    }

    // The RadioButtonRenderer class
    class RadioButtonRenderer implements TableCellRenderer {
        private JRadioButton button;

        public RadioButtonRenderer() {
            button = new JRadioButton();
            button.setHorizontalAlignment(JRadioButton.CENTER);
        }

        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
            if (value == null) {
                button.setSelected(false);
            } else {
                button.setSelected((Boolean) value);
            }
            return button;
        }
    }

    public static void main(String args[]) {
        TestJTable frame = new TestJTable();
        frame.setVisible(true);
    }
}

该示例中创建了一个 JTable，其中包含一个带有单选框的 Gender 列。RadioButtonEditor 和 RadioButtonRenderer 类用于设置单选框的编辑器和渲染器。RadioButtonEditor 用于设置单元格编辑器，RadioButtonRenderer 用于设置单元格呈现器。该示例还包含使用按钮组的单选按钮。
