{
    QTableWidgetItem *item=filesTable->itemAt(point);
 
 
 
     QPoint globalpos=filesTable->mapToGlobal(point);
       QString cell=item->text();
       cout<<"EVENT GENERATED..."<<cell.toStdString()<<endl;
 
       QAction *pAddAction= new QAction("add",filesTable);
       QAction *pSplitAction= new QAction("SPLIT",filesTable);
       QMenu *pContextMenu = new QMenu( this);
       pContextMenu->addAction(pAddAction);
       pContextMenu->addAction(pSplitAction);
       pContextMenu->exec(globalpos);
 
   }

void MainWindow::ProvideContextMenu(const QPoint &point)
{
    QTableWidgetItem *item=filesTable->itemAt(point);
    
    
    
     QPoint globalpos=filesTable->mapToGlobal(point);
       QString cell=item->text();
