Copy selected rows of a table to a model

I want to make a new model containing only the selected rows of this table.
Appending the selected rows to the empty model named "selected_rows_model" (QSqlTableModel).

Code:

---

QItemSelectionModel *selectionModel = ui.devices_finder_tbl->selectionModel();
    if(selectionModel->hasSelection() ){       
            //QModelIndexList list = selectionModel->selectedRows();
             QModelIndexList list = ui.devices_finder_tbl->selectedIndexes();
            for(int i = 0; i < list.size(); i++)
            {
                QModelIndex index = list.at(i);
                selected_rows_model->insertRow(selected_rows_model->rowCount(), index);
            }
	}

---

But it's not working, this row:

Code:

---

selected_rows_model->insertRow(selected_rows_model->rowCount(), index);

---

is wrong.
Ho can I fix it?

QModelIndex is specific to the model, it cannot be copied/supplied to another model. You will have to create another new QModelIndex for the selected_rows_model.

How can I do this? Can you give me an example?

You can create a new QModelIndex using

Code:

---

QAbstractItemModel::index()

---

Here is a working example.

Code:

---

class SelectionCopier : public QObject
{
    Q_OBJECT
public:
    explicit SelectionCopier(const QAbstractItemView * from, QAbstractItemView * to, QObject * parent = 0)
        : QObject(parent)
        , mFromTable(from)
        , mToTable(to)
    {
        mToTable->setModel(new QStandardItemModel(mToTable));
 
        connect(from, SIGNAL(pressed(QModelIndex)), SLOT(copySelection()));
    }
 
protected slots:
    void copySelection()
    {
        const QAbstractItemModel * fromModel = mFromTable->model();
        QAbstractItemModel * toModel = mToTable->model();
 
        toModel->removeRows(0, toModel->rowCount());
        toModel->removeColumns(0, toModel->columnCount());
 
        QItemSelectionModel * selectionModel = mFromTable->selectionModel();
 
        if(selectionModel->hasSelection())
        {
            toModel->insertColumns(0, fromModel->columnCount());
 
            QList<int> rows;
 
            foreach(const QModelIndex & modelIndex, selectionModel->selectedIndexes())
            {
                if(!rows.contains(modelIndex.row()))
                {
                    rows.append(modelIndex.row());
                    toModel->insertRow(toModel->rowCount());
                }
 
                const int row = rows.indexOf(modelIndex.row());
                const int col = modelIndex.column();
 
                const QModelIndex index = toModel->index(row, col);
 
                for(int role = 0; role < Qt::UserRole; ++role)
                    toModel->setData(index, modelIndex.data(role), role);
            }
        }
    }
 
private:
    const QAbstractItemView * const mFromTable;
    QAbstractItemView * const mToTable;
};
