Could you share that somewhere (preferably under LGPL, GPL or even BSD)? I was thinking of writing a wrapper class for that as well. A thing i also miss is having to ability to set filters in QSortFilterProxyModel without the need to subclass it. That would be possible if it takes a lambda as argument for filtering. > > Mathias Baumann schreef op 22-5-2015 om 18:16: > > Hello, > > > > I am using a QSortFilterProxyModel with QML.
