Edit QStandardItem text remote when using proxyfiltermodel to filter data

[andsun]

Hi, I can't figure out how to change the text in my QTableView from code when I'm using a proxy filter.
Any help is appreciated

I am using a QTableView to hold a large amount of data within a QStandardItemModel.
I'm using a combobox to let the user filter the data to manageable size and a QProxyFilterModel to do the actual filtering.
Now when I want to change the filtered data with code, I don't understand how to get the say first filtered row and third column item to set new data to.

By pure chance did I find this, and after my modification, and it seems to work
ui->tblView->model()->setData(ui->tblView->model()->index(1,4,QModelIndex()), QString("Testar"), Qt::EditRole);

So if I got this right, since I set my QTableView Model to the proxymodel and filter with. The above tblView->model() returns the result from the filter as a model....
Also, using ->setData let min change the data as long as I'm using the QStandardItem in my model plus using Qt::EditRole.
