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

[Paul Dixon]

I have a model derived from QSqlQueryModel. If I give the model a
query, it seems my application can no longer perform database updates
using QSqlQuery. No errors are returned from the database when making
these failed updates. If I comment out the line giving the model a
query, updates work again.

Anyone got any idea what might have happened? I am using Qt4.5
