I have posted code above. Where I am calling pMenu->clear();

Qt Code: 
  1. QString strAg = "ITEM %1";
  2.     QMenu * pMenu = new QMenu;
  3.  
  4.     if(pMenu)
  5.     {
  6.     pMenu->clear(); //CLEAR DOES NOT WORK
  7.     disconnect(pMenu,0,0,0);
  8.  
  9.     for ( int item = 0; item < m_strItemList.count(); ++item )
  10.     {
  11.  
  12.    QAcrion * pAction = pMenu->addAction(strArg.arg(m_strItemList[item] )); //Adding Action to the Menu
  13.  
  14.     QSignalMapper* mapper = new QSignalMapper(pMenu);
  15.     mapper->setMapping(pAction, 1)
  16.     connect(pAction, SIGNAL(triggered()), mapper, SLOT(map()));
  17.     connect(mapper, SIGNAL(mapped(int)), this, SLOT(RunItem(int)));
  18.  
  19.     }
