Sequence of inverted data row in Qtableview

Hi,
I have a problem reading data from a file and presenting it in a QtableView, the sequence of the data row is reversed. I am using the insertRow (int position, int rows, const QModelIndex & index) function of the AddressBook example in the QtableModel, that is, beginInsertRows (QModelIndex (), position, position + rows - 1); .... endInsertRows (). When calling the function insertRow () I put
int rowPosition = 0;
tableModel-> insertRows (rowPosition, 1, QModelIndex ());
rowPosition ++; // Number of rows I have added
but the rows are presented in an inverted order as in the figures.
How do I present the rows in the proper order?
thanks for help me.

The beginInsertRows() and endInsertRows() functions are for use inside the model implementation around the logic that populates the model's internal data structures.
The insertRows() function is a public API for manipulating the model content from outside the model.

Are you implementing a table model of your own, or are you simply populating a QStandardItemModel (or similar existing model)?

if you are doing the latter then this works:

Code:

---

#include <QApplication>
#include <QStandardItemModel>
#include <QTableView>
#include <QFile>
#include <QTextStream>
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
 
    QStandardItemModel model;
    model.setColumnCount(10);
 
    QFile file("test.txt");
    if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return 1;
 
    QTextStream in(&file);
    while (!in.atEnd()) {
        int row = model.rowCount();
        model.insertRow(row);
        double value;
        for (int col = 0; col < 10; ++col) {
            in >> value;
            model.setData(model.index(row, col), value);
        }
        in.skipWhiteSpace();
    }
 
    QTableView view;
    view.setModel(&model);
    view.show();
    return app.exec();
}
