How do you add a QActionGroup to a QMenuBar?

Just wondering how to add a QActionGroup to a QMenuBar?

I know how to add a QAction, just can't find how to add a QActionGroup.

You need to setup the QActionGroup before its added, right?

Thanks in advance

Yeah I worked it out:

Qt Code:

Switch view

//////////////////
        // Setup menu bar.
        //////////////////
    QAction *menuAction;
    QActionGroup *menuActionGroup = new QActionGroup(this);
    QMenuBar *menuBar = new QMenuBar(this);
 
    QMenu *menu = menuBar->addMenu("File");
    menuAction = menu->addAction("Load");
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Load_Configuration()));
    menuAction = menu->addAction("Save");
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Save_Configuration()));
 
    menuActionGroup->setExclusive(true);
    menu = menuBar->addMenu("ComPort");
    menuAction = menu->addAction("No Port");
    menuAction->setChecked(true);
    menuAction->setCheckable(true);
    menuActionGroup->addAction(menuAction);
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Select_ComPort0()));
    menuAction = menu->addAction("Com 1");
    menuAction->setCheckable(true);
    menuActionGroup->addAction(menuAction);
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Select_ComPort1()));
    menuAction = menu->addAction("Com 2");
    menuAction->setCheckable(true);
    menuActionGroup->addAction(menuAction);
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Select_ComPort2()));

//////////////////
        // Setup menu bar.
        //////////////////
    QAction *menuAction;
    QActionGroup *menuActionGroup = new QActionGroup(this);
    QMenuBar *menuBar = new QMenuBar(this);

    QMenu *menu = menuBar->addMenu("File");
    menuAction = menu->addAction("Load");
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Load_Configuration()));
    menuAction = menu->addAction("Save");
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Save_Configuration()));

    menuActionGroup->setExclusive(true);
    menu = menuBar->addMenu("ComPort");
    menuAction = menu->addAction("No Port");
    menuAction->setChecked(true);
    menuAction->setCheckable(true);
    menuActionGroup->addAction(menuAction);
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Select_ComPort0()));
    menuAction = menu->addAction("Com 1");
    menuAction->setCheckable(true);
    menuActionGroup->addAction(menuAction);
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Select_ComPort1()));
    menuAction = menu->addAction("Com 2");
    menuAction->setCheckable(true);
    menuActionGroup->addAction(menuAction);
    connect(menuAction, SIGNAL(triggered()), this, SLOT(Select_ComPort2()));
