Don't use the undocumented QVariant::data() method designed for some Qt's internal purposes. Use QVariant::value():sqlite3* handler = v.value<sqlite3*>();
However, Scott's code fragment is almost identical to the one in the QSqlDriver::handle() documentation, so if this does not work, the docs should be updated...
Scott: Did you try something simpler than creating a function with the returned handler? I am not familiar with the sqlite API, but there should be some trivial call that would verify that the handler is valid. And does *handler look reasonable when viewed in a debugger?
