The following members of class QAbstractItemModel are obsolete. They are provided to keep old source code working. We strongly advise against using them in new code.
Resets the model to its original state in any attached views.
Note: Use beginResetModel() and endResetModel() instead whenever possible. Use this method only if there is no way to call beginResetModel() before invalidating the model. Otherwise it could lead to unexpected behaviour, especially when used with proxy models.
Instead you should use:
beginResetModel(); myData.clear(); endResetModel();
