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:

Qt Code: 
  1. H3DMainWindow::H3DMainWindow(QWidget *parent):
  2.         QMainWindow(parent)
  3. {
  4.     setupUi(this);
  5.  
  6.     configureActions();
  7.     configureMenus();
  8. }
  9.  
  10. H3DMainWindow::~H3DMainWindow()
  11. {
  12.  
  13. }
  14.  
  15. void H3DMainWindow::configureActions()
  16. {
  17.     m_actionEXAMINE = new QAction(tr("EXAMINE"),this);
  18.     m_actionEXAMINE->setChecked(true);
  19.  
  20.     m_actionFLY = new QAction(tr("FLY"),this);
  21.  
  22.     m_actionWALK = new QAction(tr("WALK"),this);
  23.  
  24.     m_actionLOOKAT = new QAction(tr("LOOKAT"),this);
  25.  
  26.     m_actionNONE = new QAction(tr("NONE"),this);
  27.  
  28.  
  29.     //create the action group and add the actions to the group
  30.     m_navigationGroup = new QActionGroup(this);
  31.     m_navigationGroup->addAction(m_actionEXAMINE);
  32.     m_navigationGroup->addAction(m_actionFLY);
  33.     m_navigationGroup->addAction(m_actionWALK);
  34.     m_navigationGroup->addAction(m_actionLOOKAT);
  35.     m_navigationGroup->addAction(m_actionNONE);
  36. }
  37.  
  38. void H3DMainWindow::configureMenus()
  39. {
  40.     //configure the navigation menu
  41.     menu_Navigation->addAction(m_actionEXAMINE);
  42.     menu_Navigation->addAction(m_actionFLY);
  43.     menu_Navigation->addAction(m_actionWALK);
  44.     menu_Navigation->addAction(m_actionLOOKAT);
  45.     menu_Navigation->addAction(m_actionNONE);
  46.     menu_Navigation->addSeparator();
  47. }
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 ?
