Q: How to make MySql DataBase Conection with QML

Hi guys can any one give an example of, how to conect an MySql DB to QML, i know it's possible with C++, but i dont understand C++.

I have some code, witch i got from an project i downloaded but i dont understand it, so could some one at least explain me the code??

Code:

---

#include "connecttodatabase.h"
 
ConnectToDatabase::ConnectToDatabase()
{
}
 
void ConnectToDatabase::doConnect(QString driver, QString hostname, QString databasename, QString username, QString password)
{
    m_db = QSqlDatabase::addDatabase(driver);
    m_db.setHostName("localhost");
    m_db.setDatabaseName("ecolover");
    m_db.setUserName("root");
    m_db.setPassword("");
    m_db.open();
}
 
 
QSqlDatabase ConnectToDatabase::con() const
{
    return m_db;
}

Code:

---

#ifndef CONNECTTODATABASE_H
#define CONNECTTODATABASE_H
#include <QtSql/QSqlDatabase>
 
class ConnectToDatabase
{
public:
    ConnectToDatabase();
    QSqlDatabase con() const;
    void doConnect(QString driver, QString hostname, QString databasename, QString username, QString password);
private:
    QSqlDatabase m_db;
};
 
#endif // CONNECTTODATABASE_H
