QActionGroup issue

[sajis997]

Hello forum,


I have just recently updated the qt to 4.8.

I have some .ui file from the previous version and i am continuing working on it. I am trying to crate a simple QActionGroup to the menu as follows:

H3DMainWindow::H3DMainWindow(QWidget *parent):
        QMainWindow(parent)
{
    setupUi(this);
 
    configureActions();
    configureMenus();
}
 
H3DMainWindow::~H3DMainWindow()
{
 
}
 
void H3DMainWindow::configureActions()
{
    m_actionEXAMINE = new QAction(tr("EXAMINE"),this);
    m_actionEXAMINE->setChecked(true);
 
    m_actionFLY = new QAction(tr("FLY"),this);
 
    m_actionWALK = new QAction(tr("WALK"),this);
 
    m_actionLOOKAT = new QAction(tr("LOOKAT"),this);
 
    m_actionNONE = new QAction(tr("NONE"),this);
 
 
    //create the action group and add the actions to the group
    m_navigationGroup = new QActionGroup(this);
    m_navigationGroup->addAction(m_actionEXAMINE);
    m_navigationGroup->addAction(m_actionFLY);
    m_navigationGroup->addAction(m_actionWALK);
    m_navigationGroup->addAction(m_actionLOOKAT);
    m_navigationGroup->addAction(m_actionNONE);
}
 
void H3DMainWindow::configureMenus()
{
    //configure the navigation menu
    menu_Navigation->addAction(m_actionEXAMINE);
    menu_Navigation->addAction(m_actionFLY);
    menu_Navigation->addAction(m_actionWALK);
    menu_Navigation->addAction(m_actionLOOKAT);
    menu_Navigation->addAction(m_actionNONE);
    menu_Navigation->addSeparator();
}

H3DMainWindow::H3DMainWindow(QWidget *parent):
        QMainWindow(parent)
{
    setupUi(this);

    configureActions();
    configureMenus();
}

H3DMainWindow::~H3DMainWindow()
{

}

void H3DMainWindow::configureActions()
{
    m_actionEXAMINE = new QAction(tr("EXAMINE"),this);
    m_actionEXAMINE->setChecked(true);

    m_actionFLY = new QAction(tr("FLY"),this);

    m_actionWALK = new QAction(tr("WALK"),this);

    m_actionLOOKAT = new QAction(tr("LOOKAT"),this);

    m_actionNONE = new QAction(tr("NONE"),this);


    //create the action group and add the actions to the group
    m_navigationGroup = new QActionGroup(this);
    m_navigationGroup->addAction(m_actionEXAMINE);
    m_navigationGroup->addAction(m_actionFLY);
    m_navigationGroup->addAction(m_actionWALK);
    m_navigationGroup->addAction(m_actionLOOKAT);
    m_navigationGroup->addAction(m_actionNONE);
}

void H3DMainWindow::configureMenus()
{
    //configure the navigation menu
    menu_Navigation->addAction(m_actionEXAMINE);
    menu_Navigation->addAction(m_actionFLY);
    menu_Navigation->addAction(m_actionWALK);
    menu_Navigation->addAction(m_actionLOOKAT);
    menu_Navigation->addAction(m_actionNONE);
    menu_Navigation->addSeparator();
}

To copy to clipboard, switch view to plain text mode 

But the action group is not working. I am supposed have radio button beside each of the actions, it shows something like this

As you can see in the attached image there is a menu called navigation and several items are added to the menu, But i am not getting the radio buttom beside each of them.


What am i missing ?

From the docs under QAction::setChecked()]:

Only checkable actions can be checked.

See QAction::setCheckable()
