My problem is to navigate the tab headers using keyboard for QTabWidget.
My whole code look like follows .

class ABC :: QObject 
{ 
      Public :
             ABC();
 }
 
void ABC::ABC()
{
   .......  
   .......   
  QTabWidget  m_pMasterTab = new QTabWidget();
    m_pMasterTab->installEventFilter(this);//event filter
 }
//Event filter
bool ABC::eventFilter(QObject * target, QEvent * event)
{
    int cnt = m_pMasterTab->count();
 
    if(event->type() == QEvent::KeyPress)
    {
        QKeyEvent *k = (QKeyEvent*)event;
        Qt::Key keyPressed = (Qt::Key)k->key();
        if(keyPressed == Qt::Key_Left)
        {
            int indx = m_pMasterTab->currentPageIndex();
            m_pMasterTab->setCurrentPage ((indx ==0)?cnt:indx-1 ) ;
        }
        if(keyPressed == Qt::Key_Right)
        {
            int indx = m_pMasterTab->currentPageIndex();
            m_pMasterTab->setCurrentPage ((indx+1)%cnt ) ;
        }
 
    }
    return QObject::eventFilter( object, event );
}

class ABC :: QObject 
{ 
      Public :
             ABC();
 }

void ABC::ABC()
{
   .......  
   .......   
  QTabWidget  m_pMasterTab = new QTabWidget();
    m_pMasterTab->installEventFilter(this);//event filter
 }
//Event filter
bool ABC::eventFilter(QObject * target, QEvent * event)
{
    int cnt = m_pMasterTab->count();

    if(event->type() == QEvent::KeyPress)
    {
        QKeyEvent *k = (QKeyEvent*)event;
        Qt::Key keyPressed = (Qt::Key)k->key();
        if(keyPressed == Qt::Key_Left)
        {
            int indx = m_pMasterTab->currentPageIndex();
            m_pMasterTab->setCurrentPage ((indx ==0)?cnt:indx-1 ) ;
        }
        if(keyPressed == Qt::Key_Right)
        {
            int indx = m_pMasterTab->currentPageIndex();
            m_pMasterTab->setCurrentPage ((indx+1)%cnt ) ;
        }

    }
    return QObject::eventFilter( object, event );
}

Looks like a double thread to me. And this is not related to Qt Designer either..
