Closing correctly sqlite connection?

Hi,
I want to delete a sqlite database, on linux and mac i have no problems, but in windows i can't delete the sql file because "It is in use". So my question is, how do you close in the right way the database?

Is this wrong?

Code:

---

db->close();
db->removeDatabase("QSQLITE");

---

QSqlDatabase::removeDatabase() is static so call:

Code:

---

{
  QSqlDatabase db;
  db.setDatabaseName("somename");
  //...
  db->close();
}
QSqlDatabase::removeDatabase("somename");
