使用JFace数据绑定单选按钮组的正确方法

// 创建数据模型
class MyModel {
    private String selectedValue;
    // getter and setter
}

// 创建单选按钮组
Button[] radioButtons = new Button[3];
radioButtons[0] = new Button(parent, SWT.RADIO);
radioButtons[0].setText("Option 1");
radioButtons[1] = new Button(parent, SWT.RADIO);
radioButtons[1].setText("Option 2");
radioButtons[2] = new Button(parent, SWT.RADIO);
radioButtons[2].setText("Option 3");

// 创建数据绑定
MyModel model = new MyModel();
ButtonGroupDataBinding binding = new ButtonGroupDataBinding(radioButtons);
binding.bindValue(JFaceDataBindingUtil.createValueBinding(model, "selectedValue"));

// 更新数据模型
model.setSelectedValue("Option 2");

// 获取选中值
String selectedValue = model.getSelectedValue();
