No Sort Vertical Header

[wirasto]

By using QSortFilterProxyModel, then when sorting, the sequence of the vertical header in QTableView also changed. How do I not change order number in the vertical header when column sorted ?



Sorry, my english is bad

Reimplement headerData() on the proxy and always return the regular sequence of row numbers.

OK, I so confused. Can you give me example code ?

QVariant myProxy::headerData(int section, Qt::Orientation orientation, int role) const {
  if(orientation!=Qt::Vertical || role!=Qt::DisplayRole)
    return QSortFilterProxyModel::headerData(section, orientation, role);
  return section;
}

QVariant myProxy::headerData(int section, Qt::Orientation orientation, int role) const {
  if(orientation!=Qt::Vertical || role!=Qt::DisplayRole)
    return QSortFilterProxyModel::headerData(section, orientation, role);
  return section;
}

To copy to clipboard, switch view to plain text mode

That's can start from 0

So, i chane like this

QVariant MyProxy::headerData(int section, Qt::Orientation orientation, int role) const {
  if(orientation!=Qt::Vertical || role!=Qt::DisplayRole)
    return QSortFilterProxyModel::headerData(section, orientation, role);
 
  return section+1;
}

QVariant MyProxy::headerData(int section, Qt::Orientation orientation, int role) const {
  if(orientation!=Qt::Vertical || role!=Qt::DisplayRole)
    return QSortFilterProxyModel::headerData(section, orientation, role);

  return section+1;
}

To copy to clipboard, switch view to plain text mode 

Thank's for your sample code. Solved now.
