    @NOUElement.appendChild( xmlDocument.createTextNode(ui->tableWidget_5->rowCount().toString()));@

    @'((MainWindow*)this)->MainWindow::ui->Ui::MainWindow::<anonymous>.Ui_MainWindow::tableWidget_5->QTableWidget::rowCount()', which is of non-class type 'int'@

    Help please?

      Well, AFAIK there is no toString() function defined for integer type... You may be looking for QString::number()

        you are calling toString() on an integer ?!
        Edit: too slow :)

          Epic, I come from the visual basic edge of this world, you know? :P I'm not that familiar with C++. What can I do to put the rowCount in the Element? Somehow I have to convert it in a string.

            Okay, I've found it in the documentation.
            @QString numberOfRows = QString::number(ui->tableWidget_5->rowCount());@

            Thanks!

              Hi!
              Also you can:
              @QString numberOfRows;
              numberOfRows.setNum(ui->tableWidget_5->rowCount())@
              or
              @QString numberOfRows = QString("%1").arg(ui->tableWidget_5->rowCount());@
              or
              @QLocale loc;
              QString str = loc.toString(ui->tableWidget_5->rowCount());@
