i need to use Alt+Ctrl+arrow keys combination

[prasad.ece2]

fine bro its working but the problem is as soon as i press Alt+Ctrl it going to default case (Use Only Arrow Keys), Alt+Ctrl+any arrow key it is going to default case only.

i have done as below

void CBoxViewItem::keyPressEvent(QKeyEvent* f_event)
{
  if(f_event->KeyPress)
  {
     QKeyEvent * keyEvent = static_cast<QKeyEvent *>(f_event);
 
         if(f_event->type() == QEvent::KeyPress)
        {
            if(f_event->modifiers().testFlag(Qt::AltModifier) &&  f_event->modifiers().testFlag(Qt::ControlModifier) )
            {
                switch(f_event->key())
                {
                case Qt::Key_Left: 
                    qDebug()<<"Alt + Ctrl + Key_Left"; 
                    break;
                case Qt::Key_Up: 
                    qDebug()<<"Alt + Ctrl + Key_Up"; 
                    break;
                case Qt::Key_Right: 
                    qDebug()<<"Alt + Ctrl + Key_Right"; 
                    break;
                case Qt::Key_Down: 
                    qDebug()<<"Alt + Ctrl + Key_Down"; 
                    break;
                default: 
                    qDebug()<<"Use Only Arrow Keys"; 
                    break;
                }
           }
       }
   }

void CBoxViewItem::keyPressEvent(QKeyEvent* f_event)
{
  if(f_event->KeyPress)
  {
     QKeyEvent * keyEvent = static_cast<QKeyEvent *>(f_event);
    
         if(f_event->type() == QEvent::KeyPress)
        {
            if(f_event->modifiers().testFlag(Qt::AltModifier) &&  f_event->modifiers().testFlag(Qt::ControlModifier) )
            {
                switch(f_event->key())
                {
                case Qt::Key_Left: 
                    qDebug()<<"Alt + Ctrl + Key_Left"; 
                    break;
                case Qt::Key_Up: 
                    qDebug()<<"Alt + Ctrl + Key_Up"; 
                    break;
                case Qt::Key_Right: 
                    qDebug()<<"Alt + Ctrl + Key_Right"; 
                    break;
                case Qt::Key_Down: 
                    qDebug()<<"Alt + Ctrl + Key_Down"; 
                    break;
                default: 
                    qDebug()<<"Use Only Arrow Keys"; 
                    break;
                }
           }
       }
   }
