Switch widgets in a QTableWidget



  • Hi everybody, I'm trying to use a QTableWidget who contains QWidget (not QItems).
    I tried to switch two widgets using Drag&Drop but I found a problem:
    -When I call the cellWidget(row,col) method I get the instance of QWidget, but the QTableWidget kept the reference to that QWidget, so when I use setCellWidget in the same (row,col) it remove the QWidget.
    An example to clearify:

    @
    //dragEnterEvent

        previousRow = rowAt(event->pos().y());
        previousCol = columnAt(event->pos().x());
        previousWidget = cellWidget(previousRow,previousCol);
    

    //dropEvent

    QWidget *currentWidget = cellWidget(currentRow,currentCol);
    setCellWidget(currentRow,currentCol,previousWidget);
    setCellWidget(previousRow,previousCol,currentWidget);
    

    @

    When I do that, I remove both QWidget... I tried to set a null pointer to the cell (setCellWidget(row,col,0) after getting the cellWidget, but It didn't work...

    Any idea? Thanks!
