如何在JTable中将JRadioButton添加到组中

本文介绍了如何在JTable中将JRadioButton添加到组中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已使用渲染器和编辑器将单选按钮添加到 JTable 。我也创建了同样的组。我无法使用此原则实现排他性（只应选择1个单选按钮）。请参阅下面的代码并感谢您的回复。

渲染器和编辑器类：

class RadioButtonRenderer实现TableCellRenderer { public Component getTableCellRendererComponent（JTable table，Object value， boolean isSelected，boolean hasFocus，int row，int column）{ if（ if（ value == null）返回null; 返回（组件）值; } } 类RadioButtonEditor扩展DefaultCellEditor实现ItemListener { private JRadioButton button; public RadioButtonEditor（JCheckBox checkBox）{ super（checkBox）; } public Component getTableCellEditorComponent（JTable table，Object value， boolean isSelected，int row，int column）{ if（value == null）返回null; button =（JRadioButton）值; button.addItemListener（this）; 返回（组件）值; } public Object getCellEditorValue（）{ button.removeItemListener（this）; 返回按钮; } public void itemStateChanged（ItemEvent e）{ super.fireEditingStopped（）; } }

这是准备数据和分组的地方完成：

private void displayPhoneListShow（Person person）{ DefaultTableModel dm = new DefaultTableModel（）{ @Override public boolean isCellEditable（int row，int column）{ return true; } }; Object [] objects = new Object [3]; Object [] tableColumnNamesPhone = new Object [3]; tableColumnNamesPhone [0] =选择; tableColumnNamesPhone [1] =电话号码; tableColumnNamesPhone [2] =首选; dm.setColumnIdentifiers（tableColumnNamesPhone）; ListIterator< Phone> phoneList = person.getPhoneList（）。listIterator（）; while（phoneList.hasNext（））{ Phone phone = phoneList.next（）; objects [0] = new JRadioButton（（^））; objects [1] = phone.getPhoneNumber（）; objects [2] = phone.getPreferred（）; dm.addRow（objects）; } this.phoneTable.setModel（dm）; ButtonGroup group = new ButtonGroup（）; for（int row = 0; row< dm.getRowCount（）; row ++）{ JRadioButton radio =（JRadioButton）dm.getValueAt（row，0）; group.add（电台）; } phoneTable.getColumn（Select）。setCellRenderer（ new RadioButtonRenderer（））; phoneTable.getColumn（Select）。setCellEditor（ new RadioButtonEditor（new JCheckBox（）））; }

我仍然无法达到结果。我还尝试添加 ButtonGroup group = new ButtonGroup（）作为类变量，也是 RadioButtonRenderer 类的一部分为此组添加了按钮。但结果却无动于衷。

请建议。

解决方案

替代方案，使用 JComboBox 作为的图，Mac OS X：

图使用 DefaultTableCellRenderer 和 DefaultCellEditor ，Windows（见评论）：

I have added radio buttons to a JTable using renderer and editor. I have also created group for the same. I'm unable to achieve the exclusiveness (only 1 radio button should be selected) using this principle. Please see my code below and appreciate your response.

Renderer and Editor classes:

class RadioButtonRenderer implements TableCellRenderer { public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { if (value == null) return null; return (Component) value; } } class RadioButtonEditor extends DefaultCellEditor implements ItemListener { private JRadioButton button; public RadioButtonEditor(JCheckBox checkBox) { super(checkBox); } public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) { if (value == null) return null; button = (JRadioButton) value; button.addItemListener(this); return (Component) value; } public Object getCellEditorValue() { button.removeItemListener(this); return button; } public void itemStateChanged(ItemEvent e) { super.fireEditingStopped(); } }

This is where the data is prepared and the grouping is done:

private void displayPhoneListShow(Person person) { DefaultTableModel dm = new DefaultTableModel() { @Override public boolean isCellEditable(int row, int column) { return true; } }; Object[] objects = new Object[3]; Object[] tableColumnNamesPhone = new Object[3]; tableColumnNamesPhone[0] = "Select"; tableColumnNamesPhone[1] = "Phone Number"; tableColumnNamesPhone[2] = "Preferred"; dm.setColumnIdentifiers(tableColumnNamesPhone); ListIterator<Phone> phoneList = person.getPhoneList().listIterator(); while (phoneList.hasNext()) { Phone phone = phoneList.next(); objects[0] = new JRadioButton(("^")); objects[1] = phone.getPhoneNumber(); objects[2] = phone.getPreferred(); dm.addRow(objects); } this.phoneTable.setModel(dm); ButtonGroup group = new ButtonGroup(); for (int row = 0; row < dm.getRowCount(); row++) { JRadioButton radio = (JRadioButton) dm.getValueAt(row, 0); group.add(radio); } phoneTable.getColumn("Select").setCellRenderer( new RadioButtonRenderer()); phoneTable.getColumn("Select").setCellEditor( new RadioButtonEditor(new JCheckBox())); }

I am still unable to achieve the result. I have also tried adding ButtonGroup group = new ButtonGroup() as a class variable and also part of the RadioButtonRenderer class and added buttons to this group. But results were indifferent.

Please suggest.

解决方案

As an alternative, use a JComboBox as an editor for mutually exclusive choices within a row. For convenience, DefaultCellEditor offers a constructor especially for this. The result also makes more efficient use of horizontal space in the row. DependentColumn is an example, shown below. See also these other alternatives.
