how can I get indexes of multiple selected rows in QTableWidget

I have a table where user can select multiple rows, however I need to know indexes of top and last selected row, I tried playing with http://qt-project.org/doc/qt-5/QModelIndex.html so far I have this:

QItemSelectionModel *selections = this->ui->tableWidget->selectionModel();
QModelIndexList selected = selections->selectedRows(3);

But I have no idea how can I use QItemSelectionModel to reach the item of table. How can I do that? There is no function in TableWidget that returns item based on QModelIndex, only QPoint

In order to get the first and last item in the selection range you can simply sort that list. For example:

QItemSelectionModel *selections = this->ui->tableWidget->selectionModel();
QModelIndexList selected = selections->selectedRows(3);
qSort(selected);
QModelIndex first = selected.first();
QModelIndex last = selected.last();

And now let's get the first and last table items:

QTableWidgetItem *firstItem = this->ui->tableWidget->item(first.row(), first.column());
QTableWidgetItem *lastItem = this->ui->tableWidget->item(last.row(), last.column());

Is QTableWidget::item(int row, int column) together with QModelIndex::column () and QModelIndex::row (), respectively, of any help?
