我把示例补充完整：
#include <QApplication>
#include <QWidget>
#include <QGroupBox>
#include <QRadioButton>
#include <QVBoxLayout>int main(int argc, char *argv[]) {QApplication app(argc, argv);QWidget window;window.setWindowTitle("Radio Buttons Example");QGroupBox *groupBox = new QGroupBox(QObject::tr("Exclusive Radio Buttons"), &window);QRadioButton *radio1 = new QRadioButton(QObject::tr("&Radio button 1"), &window);QRadioButton *radio2 = new QRadioButton(QObject::tr("R&adio button 2"), &window);QRadioButton *radio3 = new QRadioButton(QObject::tr("Ra&dio button 3"), &window);radio1->setChecked(true);QVBoxLayout *vbox = new QVBoxLayout;vbox->addWidget(radio1);vbox->addWidget(radio2);vbox->addWidget(radio3);vbox->addStretch(1);groupBox->setLayout(vbox);QVBoxLayout *layout = new QVBoxLayout(&window);layout->addWidget(groupBox);window.setLayout(layout);window.show();return app.exec();
}
