Sqlite3 window problem

[spirit]

on windows Qt also creates file with databasename in app directory.
but if you this like this

QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
db.setDatabaseName(":memory:");

QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
db.setDatabaseName(":memory:");

To copy to clipboard, switch view to plain text mode 

then the database will be allocated in memory.
