Why: because the layout algorithm could have a bad edge case if some columns are zero-width. (It keeps trying to fill the width of the view, but maybe it will never get there?) I ran into that while preparing for my QtWS talk about TableView. But I needed to subclass QSortFilterProxyModel anyway, to have sorting and filtering; so it was also not too hard to change the columns there by overriding mapFromSource and mapToSource. You could think of your QSortFilterProxyModel subclass as a “view model”, and use it do whatever corrections you need to make to the original model to make it presentable. At least that’s what I came up with for now. https://github.com/ec1oud/qps/blob/unsquashed/qtquick/sortfilterprocessmodel.cpp _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
