[Qt-interest] How to make QTableModeView's view content update with it's Mode?

[Kermit Mei]

Hello, I defined my TasksMode which inherited from  QAbstractTableModel.
And the data(..) method defined like this:


QVariant TaskModel::data(const QModelIndex &index, int role) const
{
  if(!index.isValid())
    return QVariant();
  if(role == Qt::DisplayRole) {
    return 
taskInfo.value(freeRecite::manager.getActiveTasks().at(index.row()))
      .at(index.column());
  }
  return QVariant();
}

But, When I update the TaskModel (modify taskInfo), the tableView can't
show the new Item, but just delete the items which has been deleted from
taskInfo.  Why?  What's wrong with my code?

Thanks!
