How to update rowCount of QTableView with QSortFilterProxy?

Question

I have a QTableView with a custom QSortFilterProxy to be able to search my data over multiple Columns. That works great so far.

Now I would like to display the row count. I would like to have something like current displayed rows / total amount of rows in database.

It's absolutely no problem to get rowCount on program start, but I am not exactly sure how I could recalculate the currently visible rows when the data has been filtered through my QSortFilterProxy.

Any help appreciated. Thank you.

You can compare return values of rowCount() function of your source and QSortFilterProxyModel models. For example, suppose model is a pointer to your QSortFilterProxyModel, than:

int filteredRowCount = model->rowCount();
int allRowCount = model->sourceModel()->rowCount();
