Instead of fixed numbers, use an enum. So the code gets more readable

I think I commented on the preprocessor macro somewhere turn it into a static function.

this

m_model->item(FileTypes_T::Datasets, 0)->appendRow(columnData);

is known as the "train wreck" anti pattern. pointers must be checked before dereferencing (e.g. in function).

Ok good to know I will change it

@felix-salfelder now I'm checking if the item is available or not.
