SqlTableModel not updating AbstractProxyModel

[victor.fernandez]

You need either to call QSortFilterProxyModel::invalidateFilter() whenever your model changes or to set the dynamicSortFilter property to true (warning: slow).

But i'm not using QSortFilterProxyModel! I'm using QAbstractProxyModel... Shall I use SortFilter instead?
It's quite nonsense, since I don't need any of the features it provides (sort and filtering).

Well, if you do not use those features, they hopefully won't use too much processing power ;-)

The source model does not have to emit dataChanged() if only a new row has been added. That is what rowsInserted() is for.

[akiross]

Oops! You're so right! I forgot about rowsInserted.
Anyway that was just a test, the problem remains: view isn't updated correctly (both on row insertion and data changing)...

The signals and slots used by the model/view framework ensure that each view is updated appropriately no matter how many proxy models are placed between itself and the source model.

Am I supposed to forward the signals when using abstract proxy models?

[caduel]

Your proxy has to tell the view all the view needs to know.
So, unless your proxy does not show a row that has been modified or inserted, yes, you will need to forward those signals.

Ok, thank you
