Adding a child of model

[_exp_]

When i add a child to model the subsequent offspring overwrites the previous , why??

void MainWindow::addChild()
{
    qDebug()<<"Slot activ";
    QModelIndex index = ui->treeView->selectionModel()->currentIndex();
    QAbstractItemModel *model = ui->treeView->model();
 
    if (model->columnCount(index) == 0) {
        if (!model->insertColumn(0, index))
        {
            return;
        }
    }
 
    if (!model->insertRow(0, index))
    {
        return;
    }
 
int column = ui->treeView->selectionModel()->currentIndex().column();
int row=ui->treeView->selectionModel()->currentIndex().row();
 
 
    model->insertColumn(column , index);
    model->setData(model->index(row, column, index), QVariant(linkWWW->text()), Qt::EditRole);
    qDebug()<<column;
 
    model->insertColumn(column +1, index);
    model->setData(model->index(row, column + 1 , index), QVariant(nameWWW->text()), Qt::EditRole);
    qDebug()<<column;
 
    model->insertColumn(column +2, index);
    model->setData(model->index(row, column + 2 , index), QVariant(tegWWW->text()), Qt::EditRole);
    qDebug()<<column;
 
    model->insertColumn(column +3, index);
    model->setData(model->index(row, column + 3 , index), QVariant(tegWWW->text()), Qt::EditRole);
    qDebug()<<column;
 
}

void MainWindow::addChild()
{
    qDebug()<<"Slot activ";
    QModelIndex index = ui->treeView->selectionModel()->currentIndex();
    QAbstractItemModel *model = ui->treeView->model();

    if (model->columnCount(index) == 0) {
        if (!model->insertColumn(0, index))
        {
            return;
        }
    }

    if (!model->insertRow(0, index))
    {
        return;
    }

int column = ui->treeView->selectionModel()->currentIndex().column();
int row=ui->treeView->selectionModel()->currentIndex().row();


    model->insertColumn(column , index);
    model->setData(model->index(row, column, index), QVariant(linkWWW->text()), Qt::EditRole);
    qDebug()<<column;

    model->insertColumn(column +1, index);
    model->setData(model->index(row, column + 1 , index), QVariant(nameWWW->text()), Qt::EditRole);
    qDebug()<<column;

    model->insertColumn(column +2, index);
    model->setData(model->index(row, column + 2 , index), QVariant(tegWWW->text()), Qt::EditRole);
    qDebug()<<column;

    model->insertColumn(column +3, index);
    model->setData(model->index(row, column + 3 , index), QVariant(tegWWW->text()), Qt::EditRole);
    qDebug()<<column;

}

To copy to clipboard, switch view to plain text mode 

the first child added to child_1 child_3
second child added to child_4 child_6
as a result of the second child of the first erased

Hi, probably the row that you use in the setData calls does not change.

tried to change the way
but it did not work

int row = rowCount(); // number of folders already in the model
  insertRow(row); // add a new row
  QModelIndex ind = index(row, 0); // index of the newly created item
  insertColumn(0, ind); // add a column for future children of the item

int row = rowCount(); // number of folders already in the model
  insertRow(row); // add a new row
  QModelIndex ind = index(row, 0); // index of the newly created item
  insertColumn(0, ind); // add a column for future children of the item

by some algorithm to change ???
