QTableView, QSortFilterProxyModel row selection

[SPlatten]

I have a QTableView this contains records from a database. I've implemented column sorting using QSortFilterProxyModel.

Before QSortFilterProxyModel, to get a row selection I used:

QItemSelectionModel* pobjModel(mptvSDrecs->selectionModel());
QModelIndexList objIndexes(pobjModel->selectedIndexes());

This worked, however now this doesn't return the correct row. Should I have changed something else?

This is how I added the filter model:

mptvSDrecs = new QTableview(this);
mpsiSDmodel = new QStandardItemModel(this);
mpsfpSDmodel = new QSortFilterProxyModel(this);
mptvSDrecs->setSelectionBehavior(QAbstractItemView::SelectRows);
mptvSDrecs->setStyleSheet(DataSets::mscszTableViewStyle);
mpsfpSDmodel->setSourceModel(mpsiSDmodel);
mptvSDrecs->setModel(mpsfpSDmodel);
mptvSDrecs->setSortingEnabled(true);

is there an example which demonstrates how to use these?

const QItemSelection proxySelect = mptvSDrecs->selectionModel()->selection();
QModelIndexList objIndexes = mpsfpSDmodel->mapSelectionToSource(proxySelect)->indexes();

Hi,

What you have selected there are the indexes from the proxy model.

From the top of my head you need to map that selection to the source model. Check QSortFilterProxyModel::mapSelectionToSource and QItemSelectionModel::selection.

QItemSelectionModel::selection

Thank you, is there an example which demonstrates how to use these?

Found https://stackoverflow.com/questions/18128722/convert-qsqlquerymodel-data-into-qvectors/18130955#18130955, do I need to sub-class QAbstractProxyModel ?
