idea 插件开发 单选框

以下是在IntelliJ IDEA插件开发中创建单选框的示例代码：

import com.intellij.openapi.ui.DialogWrapper;
import com.intellij.openapi.ui.Messages;
import com.intellij.openapi.ui.RadioButtonEnumModel;
import com.intellij.openapi.ui.ValidationInfo;
import org.jetbrains.annotations.Nullable;

import javax.swing.*;

public class MyDialog extends DialogWrapper {
    private JPanel myPanel;
    private JRadioButton radioButton1;    private JRadioButton radioButton2;
    private JRadioButton radioButton3;

    public MyDialog() {
        super(true);
        init();
        setTitle("My Dialog");
    }

    @Nullable
    @Override
    protected JComponent createCenterPanel() {
        return myPanel;
    }

    @Nullable
    @Override
    protected ValidationInfo doValidate() {
        if (!radioButton1.isSelected() && !radioButton2.isSelected() && !radioButton3.isSelected()) {
            return new ValidationInfo("Please select an option", myPanel);
        }
        return null;
    }

    @Override
    protected void doOKAction() {
        if (radioButton1.isSelected()) {
            Messages.showMessageDialog("You selected option 1", "Option Selected", Messages.getInformationIcon());
        } else if (radioButton2.isSelected()) {
            Messages.showMessageDialog("You selected option 2", "Option Selected", Messages.getInformationIcon());
        } else if (radioButton3.isSelected()) {
            Messages.showMessageDialog("You selected option 3", "Option Selected", Messages.getInformationIcon());
        }
        super.doOKAction();
    }

    public static void main(String[] args) {
        MyDialog dialog = new MyDialog();
        dialog.show();
    }
}

在这个示例中，我们使用了`JRadioButton`类来创建单选框，并将它们添加到一个`JPanel`中。我们还使用`DialogWrapper`类来创建一个对话框，并在其中显示这个面板。在`doValidate()`方法中，我们检查用户是否选择了一个选项。在`doOKAction()`方法中，我们根据用户选择的选项显示一个消息框。
