[Qt-interest] QSortFilterProxyModel Question

There's a mapToSource function that can be used to get to the original internalId.

QSortFilterProxyModel could probably have been designed to keep the same
internalId as the source model, but the fact is QSortFilterProxyModel
does not do that :) It maintains a data structure of it's own to keep
track of nodes in the source model and the internal ids reference that
data structure.
