An alternative to fetching the object and accessing properties of this object, you could use the “role” functionality of the model.
- Reference <https://doc.qt.io/qt-4.8/model-view-programming.html> (search for “role”) return idx.data(FileTypeRole) not in self._excludes Each index carries a method called data which is shorthand for model.data(index, role) <https://doc.qt.io/qt-5/qabstractitemmodel.html#data>. In this case, this would call data on the proxy model, where you either forward it to the original model, or handle it explicitly. FileTypeRole = QtCore.Qt.UserRole + 1 def data(self, index, role): if role == FileTypeRole: return ".ma" The benefit being that you avoid the trap Justin mentioned of some day switching out the underlying object, or wanting to use the same proxy in other programs where exact objects differ. In this case, you may redirect differences in the model.
