[Qt-interest] Custom SQLite Driver

[Neville Dastur]

I am writing a custom SQLite driver to use the encryption routines from 
wxSqlite. I have got the whole thing compiling and working by following 
the docs on writing your own driver 
(http://qt.nokia.com/doc/4.5/qsqldatabase.html#addDatabase-2) , but I am 
having a problem including a new method.

To set a password on the database the ReKey function needs to be called. 
I created a public method:
 void QSQLiteDriver::ReKey(const QString & key)

When calling QSQLDatabase m_db->driver()->ReKey("test"); the function 
ReKey can't be found.
 and

QSQLiteDriver *driver = m_db->driver();
driver->ReKey("test");

results in an invalid conversion.

What is this the best way of adding new functionality to a QSQLDriver.

Thanks
