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;

}

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

by some algorithm to change ???
