QGroupBox的使用

#ifndef MAINWINDOW_H#define MAINWINDOW_H#include <QMainWindow>#include <QGroupBox>namespace Ui {class MainWindow;}class MainWindow : public QMainWindow{    Q_OBJECTpublic:    explicit MainWindow(QWidget *parent = 0);    ~MainWindow();private:    QGroupBox *createFirstExclusiveGroup();    QGroupBox *createSecondExclusiveGroup();    QGroupBox *createNonExclusiveGroup();    QGroupBox *createPushButtonGroup();    Ui::MainWindow *ui;};#endif // MAINWINDOW_H

下面是cpp
