Hi, I tried to overload the setData() function as followed, but the behavior is the same which means that the view/delegate doesn't get updated:
bool ret = QStandardItemModel::setData(index, value, role); emit dataChanged(this->index(0, 0), this->index(rowCount(), columnCount())); return ret; I also tried: .) to update only the changed row => same effect: emit dataChanged(this->index(index.row(), 0), this->index(index.row(), columnCount())); .) calling a QTimer::singleShot(500) in the setData() => same effect .) deactivate the QSortFilterProxyModel and use only the QStandardItemModel => same effect .) various combinations from those points => same effect Do I need to do something special for the delegate and/or for the view?
