[Qt-interest] Does a QSqlQueryModel lock an entire sqlite database?

That was it! Thanks for the tip, I'm curious to know if its documented
somewhere and I missed it ;)

Anyway, during setData I ate the remaining data with

  while (canFetchMore())
     fetchMore();


And then updates worked. Is that the most efficient workaround though?
