Having a QSqlDatabase as a class member and avoid the connection still in use warning

Hi,

I have a class that has a QSqlDatabase as a private member.

Code:

---

private:
    QSqlDatabase m_database;

---

I use m_database in several functions of the class like:

Code:

---

QSqlQuery *query = new QSqlQuery(m_database);
 
..
 
delete query;

---

However in the destructor of the class I remove the connection with

Code:

---

m_database.close();
QSqlDatabase::removeDatabase("MyConnection");

---

But I always get the warning "MyConnection' is still in use, all queries will cease to work."

How can I avoid the warning?

Set the database object to an empty one before removing the database:

Code:

---

m_database.close();
const QString cname = m_database.connectionName();
m_database = QSqlDatabase();
QSqlDatabase::removeDatabase(cname);
