[Qt-interest] QTreeView and QSortFilterProxyModel

[Alessandro Vanzulli]

Hi,

one question? How your filterAcceptsRow accept the group1row ??

It shall be discarded from the filter beacuse it does not match with your
filter criteria. Is it correct?If yes, the source of problem is located in
the filterAcceptsRow method.

Bye

Alessandro
