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??

Qt Code: 
  1. #include "connecttodatabase.h"
  2.  
  3. ConnectToDatabase::ConnectToDatabase()
  4. {
  5. }
  6.  
  7. void ConnectToDatabase::doConnect(QString driver, QString hostname, QString databasename, QString username, QString password)
  8. {
  9.     m_db = QSqlDatabase::addDatabase(driver);
  10.     m_db.setHostName("localhost");
  11.     m_db.setDatabaseName("ecolover");
  12.     m_db.setUserName("root");
  13.     m_db.setPassword("");
  14.     m_db.open();
  15. }
  16.  
  17.  
  18. QSqlDatabase ConnectToDatabase::con() const
  19. {
  20.     return m_db;
  21. }
