Moving vs. copying in drag and drop

[lana]

I'm trying to learn how to do drag and drop. I wrote a simple program which is supposed to permit the user to sort items in a table. It almost does what I want, but when the user drops items at new locations, copies are made. I can't figure out how to change it so that the original item is deleted in addition to the copy being made. Can anyone offer me some assistance? Thanks!

QApplication app(argc, argv);
 
    QTableWidget table(5, 1);
    table.horizontalHeader()->setStretchLastSection(true);
    table.setHorizontalHeaderLabels(QStringList() << "Sort Items by Dragging");
 
    table.setSelectionMode(QAbstractItemView::SingleSelection);
    table.setDragEnabled(true);
    table.setAcceptDrops(true);
    table.setDropIndicatorShown(true);
 
    const char * labels[] = { "Item D", "Item B", "Item C", "Item E", "Item A" };
    for (int i=0; i < 5; ++i)
    {
        QTableWidgetItem * item = new QTableWidgetItem(labels[i]);
        item->setFlags(item->flags() & ~Qt::ItemIsDropEnabled);
        table.setItem(0, i, item);
    }
 
    table.show();
    return app.exec();

QApplication app(argc, argv);

    QTableWidget table(5, 1);
    table.horizontalHeader()->setStretchLastSection(true);
    table.setHorizontalHeaderLabels(QStringList() << "Sort Items by Dragging");

    table.setSelectionMode(QAbstractItemView::SingleSelection);
    table.setDragEnabled(true);
    table.setAcceptDrops(true);
    table.setDropIndicatorShown(true);

    const char * labels[] = { "Item D", "Item B", "Item C", "Item E", "Item A" };
    for (int i=0; i < 5; ++i)
    {
        QTableWidgetItem * item = new QTableWidgetItem(labels[i]);
        item->setFlags(item->flags() & ~Qt::ItemIsDropEnabled);
        table.setItem(0, i, item);
    }

    table.show();
    return app.exec();

To copy to clipboard, switch view to plain text mode
