Hi,

This mailing list is there for discussions about contributions to Qt.
For questions about Qt, there is the qt-interest mailinglist which you can use 
in the future.

Regarding your question, you can simply reimplement 
QSortFilterProxyModel::filterAcceptsRow.  And don't forget to call 
invalidateFilter when the filter changes.
