How send result query database to List<QString>

[anda_skoa]

I am afraid I don't understand.
Your code already adds strings to the list, i.e. you already know how the << operator works.

Something like that?

list << query.exec("select kod_lekarstwa, nazwa from lekarstwo;");

exec() returns a bool.

You want to loop over the results. See the example in the documentation for QSqlQuery.
