How to refresh a QTableView after sorting the datasource object?

? Offline

I have a custom QTableView and QAbstractTableModel. The data is backed by a std::deque and must be sorted by a particular field. Since the actual data source has to be sorted, instead of using a proxy model I am using std::sort(). Inside my custom implementation of QAbstractTableModel::insertRows I must recall std::sort() to ensure that the newly inserted row is sorted. After calling std::sort() on the datasource, what is the proper call to make inside insertRows to refresh the view?

@bool MomentValuePairTableModel::insertRows(int32_t position, int32_t rows, const QModelIndex &)
{
beginInsertRows(QModelIndex(), position, position + rows - 1);

for (int32_t row = 0; row < rows; ++row)
{
std::deque<MomentValuePair>::iterator it = momentValuePairs.begin() + position;
momentValuePairs.insert(it, MomentValuePair());
}

endInsertRows();

// Sort the datasource.
std::sort(momentValuePairs.begin(), momentValuePairs.end());

// How to refresh the view?

emit numRowsChanged();

return true;

Hi,

You need to emit layoutChanged, see "this":http://qt-project.org/doc/qt-5/model-view-programming.html#resizable-models
